Then you wi l l a l ready know the main principles by which we are gu ided . We have held severa l thematic sess ions of the school , devoted to a particu lar aspect of improvement in chess. The a im of the sessions was not to convey specific infor mation - for this we had too l ittle t ime. It was far more important to d iscover the deficien cies in the pupils' play and to help them to eradicate them, to demonstrate the most effective ways of studying chess , and to acquaint them with general mechanisms, ideas and methods of play. You now have before you the th i rd book (there are five in a l l ) . I t is based on our work at the th i rd session of the school , devoted to the problem of improving endgame and technical mastery. During recent years the regu lations for tournaments and matches have changed sign ificantly - now games are hardly ever adjourned . Previously, after taking play into an end ing , you could investigate its subtle ties in home analysis, whereas now you have to act d i rectly at the board . Without an excellent knowledge and, what is even more important, understanding of the laws of the endgame, it is not easy to cope with this task, especial ly if account is taken of accumulated fatigue from the preced ing battle. And yet endgame mistakes are the last in the game - it is no longer possible to repair them! It is clear that today the importance of endgame and techn ical mas tery has grown sharply. I n my bookcase there are numerous weighty tomes devoted to the theory of endings . Is it conceivable to assimi late and remember a l l the information conta ined in them? It turns out that it is not at al l necessary to do th is . After read ing the fi rst part of this book, you wi l l see that 'your ' system of endgame knowledge can and should be compact, easy to assimi late and remember, and you wi l l learn how to develop it, by making the acqua intance of certa in important sections of the theory of rook and minor piece endings. The second part of the book is devoted to an analysis of compl icated practical endings. Such an analysis helps to deepen and consol idate endgame knowledge, and aid the development of tra its of character and th ink ing necessary to every player. The techn ique of converting an advantage is a stumbl ing-block for many players. To ra ise your techn ica l mastery requ i res developing in yourself certa in important ski l ls i n seeking and taking decis ions, moreover not purely chess , but, so to speak, 'psycholog ical chess' decis ions. The question of how to improve your techn ique is examined in the th ird part of the book. Here are both the 'theory ' of this question , and. 1 .:.b1 1 ! c:Ji;a2 2 .l:te1 ! 3 c:Jl;e7 aS c:Ji;b3 3 . . . a4 is hopeless : 4 c:Ji;d6 a3 5 c:Ji;c5 c:Ji;b2 6 l:.e2+ (6 c:Ji;b4 a2 7 l:te2+ c:Ji;b1 8 c:Ji;b3 is a lso good , or 7 . . . c:Ji;c 1 8 l:.xa2 c:Ji;d 1 9 c:Ji;c3) 6 . . . c:Ji;b1 (6 . . . c:Ji;b3 7 l:.xe3+) 7 c:Ji;b4 a2 8 c:Ji;b3. 4 c:Ji;d6!

Why is this? Fi rstly, they occur more often than other types. A good half of a l l the endings that occur in practice are rook endings. Second ly, here there exists a fa i rly deta i led theory of positions with a smal l amount of materia l (for example, rook and pawn against rook) , which may a lso be repeated in our games. This theory should be mas tered . I n other types of endgame the situations with a min imal number of pawns are either qu ite simple, or not very important. This means that there a knowledge of exact positions is hardly ever requ i red - it is l i kely that you wi l l never need it. I t is sufficient to know the typical ideas and methods. But in the rook endgame you cannot get by without studying a considerable number of exact positions. I offer for your attention one of the sections of rook endgame theory - endings with a pawn on the rook's fi le . As usual , we wi l l beg in our analysis with the s implest cases . And in genera l , we wi l l not delve too deeply into theory - we wi l l merely pick out the most important positions and the ideas involved with them. 1) Stronger side's king in front of the pawn A draw is inevitable. The only way to try and free the king from imprisonment is by playing the rook to b8. But then the black king wi l l stand guard in place of the rook. 1 l::th2 'it>d7 2 l::th8 �c7 3 .l::i.b8 �c1 (of course, 3 . . . l::th 1 is a lso possible) 4 �b2 �c3, and White cannot strengthen h is position . Let us move the king and rook one fi le to the right. The Theory and Practice of Rook Endings ctJ 39 Now White wins, s ince the black king does not succeed in reach ing c7. 1 .l:!.h2 c5 . With the black king at d6 it is no longer possible to escape via c5 , and a d ifferent route has to be found . 3 .Mb8 .Ma1 4 'it>b7 .l:!.b1 + 5 'it>c8 l:!.c1 + 6 'it>d8 l::!.h1 7 .U.b6+ �c5 This is the only subtle moment.

The wh ite rook is tied to the pawn and cannot move from a8. I f 1 'it>b6 , then 1 . . . ltb1 + . The king has no shelter from the vertical checks. After driving it away, the rook returns to a 1 . I should mention that other, more compl i cated and less rel iable systems of defence also exist: the black king may hide ' i n the shadow' of its wh ite opponent (say, at c3) , or, with the black rook on the 7th rank - ' in the shadow' of its own rook. We merely mention these ideas, but we wil l not study them. Sometimes they a re sufficient for a d raw, sometimes not. Let us add a wh ite pawn on h5. Noth ing has changed . B lack does not pay any attention to it . I t is also a d raw with a wh ite pawn on g5. But with a pawn on f5 White wins. After 1 f6+ �f7 ( 1 . . . '1t>xf6 2 :fa+ ; 1 . . . �h7 2 f7) 2 .l:!.h8 Black loses h is rook. I t is no accident that I have 'chewed over' these elementary cases in deta i l . You should have a very clear impression of them , and should a lways remember and make use of them when considering more compl icated positions. Khaunin - Fridman Len ingrad 1 962 In the game there fol lowed 1 . . . hxg3 2 hxg3? g4+! 3 fxg4, when a d raw was inevitable , s ince White was left with a knight's pawn (whether one or two is of no particu lar importance) . He cou ld have won by 2 h7 3 h4! 40 � The Theory and Practice of Rook Endings gxh4+ 4 �h3 �g7 5 f4 , when the f-pawn advances with decisive effect. 3) Stronger side'srook in front of the pawn ; pawn on the 6th rank The ma in d ifference between this position and the previous ones is that the wh ite king now has a shelter against vertica l checks - at a7. It heads for there, in order to free the rook from having to defend the pawn . But the black king is unable to run to the queenside: 1 . . . ci;f7? 2 'it>e4 (2 a7? 'itg7 is prematu re) 2 . . . cJ;;e7 3 a7! 'itd7(f7) 4 .l:!.h8. 2 . . . .l:!.a5 ( instead of 2 . . . �e7) is a lso hope less: 3 �d4 'it>g7 4 'itc4 �f7 5 'it>b4 .Ua 1 6 'it>b5 l:tb 1 + 7 'itc6 .l:!.a 1 8 'it>b 7 .l:!.b 1 + 9 'it> a 7 'ite7 1 0 l:tb8 �c1 1 1 'it>b7 (but not 1 1 .Ub6? 'itd7) 1 1 . . .l:tb 1 + 1 2 'it>a8 .l:!.a 1 1 3 a 7 , and a situation that is fami l iar to us arises: the black king does not reach c7 in time. I n view of this analysis , Siegbert Tarrasch considered this position to be won . But later (in 1 924) a saving plan was found . I t is based on the fact that the a6-pawn provides the king with a shelter against vertical checks, but not against horizontal checks. The rook must be transferred to f6 . 1 . . . .Uf1 +! 2 'it>e4 .Uf6! It is important to attack the pawn , in order not to release the rook from a8. The result ing posit ion is known in endgame theory as the 'Vancura posit ion' (from the name of its d iscoverer - Joseph Vancura) . What can White do? If a6-a7 there a lways fol lows . . Jla6 (of course, the black king wi l l not move from g7 and h7) . I f the pawn is defended by the k ing, there fol lows a series of checks , and then the rook returns to f6 . For example: 3 'it>d5 l:tb6 4 �c5 l:tf6! (the best square for the rook ! ) 5 �b5 .l:!.f5+! etc. I f in the d iagram we move the wh ite king to f4 , we obta in a position which was analysed in 1 950 by Pyotr Romanovsky. 1 . . . .l:i.f1 +? 2 'it>e5 .l:lf6 is now bad because of 3 .l:!.g8+ ! . But a l l the same there is no other p lan - only the switching of the rook to the 6th rank . Therefore let us p lay 1 . . . l:tc1 ! . If 2 'it>e5 there fol lows 2 . . .lk6 - and we reach Vancura's d rawn position . Wh ite must take the oppor tun ity to remove h is rook from a8: 2 l:tb8 .l:!.a1 3 .l:r.b6 (weaker is 3 .Ub7+ 'it>f6 4 a7 'it>e6). With the rook on a8 Black's king was t ied to the kingside, but now it can head towards the pawn . But this must be done cautiously: he loses after the hasty 3 . . . �f7? 4 .'it>e5 �e7 5 . .l:!.b7+ 'it>d8 6 .a7 . Correct is 3 . . . .l:r.a5! 4 We4 'it>f7! 5 'it>d4 (if 5 .l:!.h6, then 5 . . . 'it>g7 ! , but not 5 . . . cl;e7? 6 a7 Wd7 7 l:th8 ! ) 5 ... 'it>e7 6 'it>c4 �d7 7 ci;b4 Ua1 , and the draw is obvious . Note that the k ings had a race to reach the queenside. I f the wh ite king had been closer to the pawn , Black's king might not have arrived in t ime. This means that the attempt to switch the rook to the 6th rank cannot be delayed - this p lan must be carried out as soon as possib le. The system of defence examined by us is very important. In particular, th is is how the defence should be arranged when the opponent has two extra pawns - 'a' and 'h ' . The Theory and Practice of Rook Endings ltJ 41 The h-pawn does not help White - the draw is just as elementary as in the previous example. If 1 'it>b5 there fol lows 1 . . . .l:.f5+. After driving away the king , the rook contin ues its watch of the 6th rank . If the wh ite pawn is repositioned at a5, the black rook would be placed on the 5th rank, and so on . Now let us analyse a position with a- and g pawns. 1 . . . 'it>h7! 2 �h5 Threatening 3 .l:!.a7+ �g8 4 g6 and 5 'it>h6. 2 . . . .l:!.h6+! 3 'it>g4 3 gxh6? - stalemate! 3 . . . .l:!.b6 Strangely enough , in books on the endgame this posit ion is not ana lysed . I t had to be stud ied independently. White wins. The main reason is that the black rook does not have the important f6-square , and the 6th rank proves too short . 4 �5 Again threatening 5 l:Ia7+ . 4 . . . 5 �6 6 'it>e5 6 'it>f7 .:tb7+! is pointless. �b5+ l:f.b6+ 6 . . . .l:!.c6 Of course, B lack does not have time to captu re the g5-pawn: 6 . .

See how, making use of the ideas we have just examined , I was able to save a difficult ending against an ex-world champion. Karpov - Yusupov Linares 1 99 1 I t i s Karpov to move. What possib i l it ies does he have? Black must seriously reckon with 'it'c3-c4 ( immediately, or after the preparatory 4 1 a6). But, after exchang ing queens, h e can give a check on d1 and place his rook beh ind the passed pawn - this is a very important defensive resource, typical of rook endings. On prophylactic g rounds it makes sense to remove the king beforehand from the fi rst rank : 4 1 'lt>g2!? . Now after the exchange of queens the black rook does not come to the rear of the passed pawn . Even so, B lack ga ins sufficient counterplay, by continu ing 4 1 . . . cS 42 �c4 'ifxc4 43 .l:!.xc4 �c7 fol lowed by . . . �f7-e6-dS, or 42 a6 lia7 43 'i!VaS (43 l:!.a4 f4) 43 . . .'ir'c6(d6) . 41 a6 'iia2 The pawn has to be halted . In the g iven instance it is not the rook that is placed behind it , but the queen . I thought for a long t ime about the possib i l ity of continu ing the fight in the middlegame, but I d id not find anyth ing convincing and I decided not to avoid the exchange of queens. 42 'ii'c4+ Anatoly Karpov d id not th ink for long over this move.

Even grandmasters sometimes 'flounder' in stand ard theoretica l endings. Here is a tragic comic example. Szabo - Tukmakov Buenos Aires 1 970 For White it is sufficient simply to wait, keeping the a5-pawn under fi re , in order not to release the rook from the a-fi le .

He analyses the ending of a game by the winner of the championsh ip , Stuart Rachels, against g randmaster Dmitry Gure vich . It would appear that none of them, includ ing the commentator, was fami l iar with the ideas of the g iven endgame. Rachels - Gurevich USA Championsh ip , Long Beach 1 989 Mi les writes: 'S ince rook and a- and h pawns vs rook is often drawn , it is hard to bel ieve that White should win th is .

Subsequently you no longer have to think, s ince you wi l l be acting in accordance with theory. Remember: this is how Yusupov acted in his game against Karpov.

In these last two examples both the moves and the comments made by grandmasters make a comic impression , for one s imple reason - they were not sufficiently fami l iar with the basic theory of rook endings. Our next step should probably be an analysis of positions that are closely l i nked with the type of endgame a l ready stud ied - namely, endings in which each side has two or th ree pawns on the kingside and one has an extra passed pawn on the queenside (usual ly a rook's pawn ) . Such a situation often occurs in practice . But th is is a l ready another topic, and here we wil l merely mention it. I wi l l restrict myself to one example, in which the same idea was used as we saw in the Karpov-Yusupov game, but d id not see in the Rachels-Gurevich end ing : the sacrifice of a pawn to transpose into a theoretical ly d rawn position . Bakul in - Dvoretsky Moscow Team Championship 1 974 Reckoning that if 1 8 . . . �e6 the reply 1 9 tt:Jc5 was unpleasant, I wanted to play 1 8 . . . tt:Jc6. But my sense of danger operated and I began to have doubts about the position ar is ing after 1 9 c4 d4 20 tt:Jc5 b6 21 tbd3. Wh ite creates a pawn majority on the queenside, he securely blockades the d4- pawn , and he contro ls the e-fi le . The advantage is on his side: perhaps not a great advantage, but an enduring one. When I showed th is ending to Rafael Vagan ian , an expert on the French Defence, he assessed the position as unfavourable for Black. By accu rately defending , one can probably avoid defeat, but th is is a d ifficult and thankless task. Being an active player, I usual ly avoided this type of passive de fence , and endeavoured to fi nd a way of sharply changing the course of the play, of forcing events , either with the aim of clarifying the situation , or, on the contrary, of compl icating the play as much as possible. Returning to the rook move to e6, I qu ickly found the forcing variation which occurred in the game. 1 8 . . . l:!.e6!? 19 tt:Jc5 �xe1 + 48 � The Theory and Practice of Rook Endings 20 l:ixe1 �c8! 20 . . . lt:Jg6 21 lt:Jxb7 .l::tb8 22 lt:Jc5 �xb2 23 l:te8+ lt::lf8 is not worth considering - the p in on the kn ight is extremely dangerous. For example, Wh ite can p lay 24 g3 f6 25 lt:Jd7 �f7 26 l:txf8+ 'it;e7 27 �b8 . 21 l:l.xe7 'it>f8 As you see, combinative vision sometimes helps even when playing 'ted ious' end games. 22 .l:f.xb7 In the event of 22 l:ie2 l:l.xc5 the position is roughly equa l . 22 . . . 23 c3 24 �f1 24 l:tb3?? d3 25 'it>f1 .l:te5 ! . 24 . . . 25 bxc3 26 l:.xa7 .l:txc5 d4 dxc3 �xc3 Uc2 I knew for sure that th is was a draw, and a fa i rly simple one, and so without hesitation I went in for the exchanging combinat ion. Of course , had I not made a previous study of this type of endgame, I would hard ly have decided to give up a pawn . Who knows how the game would have ended after 1 8 . . . lt:Jc6 , whereas as it was I easily made a draw. Thirty years later I realised that endings of this type were by no means as harmless as I then thought. In 2003 in the theory of rook endings with an extra pawn on the wing a revolution occurred, and positions which had seemed completely drawn proved to be won or at the least very dangerous. You can find these new ideas in my articles or those of grandmaster Carsten Muller in the ar chives of the internet site Chesscafe. com, and also in my book Dvoretsky's Endgame Manual from the same publisher. If I had known about the future discoveries, I would perhaps have rejected the combination (in favour of 1 8 . . . l:l.e8!? followed by 19 . . . 'it>f8), and at the least I would have played the endgame more carefully. However, my decision to sacrifice a pawn was taken not only on purely chess grounds - it was i nfluenced , as wel l as the subse quent play, by certa in extraneous factors . At that time I was teaching in the chess department of the I nstitute of Physical Cu lture . We were p lann ing to hold a tourna ment on the Scheveningen system : stu dents (candidate masters) against masters, and I had to find some opponents for our students. The Moscow Team Champion ship, held in the Centra l Chess Club , attracted nearly a l l the Moscow masters , and th is was the most convenient place to hold d iscussions . After transposing i nto a comparatively s imple ending soon after the start of play, I ga ined the opportun ity, by making my moves without much thought, to rush to the other boards and press players who were stro l l ing about to take part in our tournament. Because my attention was d ivided , some of my moves were not the most accurate , but I nevertheless gained a draw. 27 g3 g6 28 g7 29 'it;t3 h5 30 h4 'it>f6 31 'it>e3 �c3+ 31 . . . We6 or 31 . . .

Such 'trifles' sometimes decisively affect the result of the game, and on no account should they be disregarded . Unfortunately, in a t ime scramble I commit ted a sign ificant inaccuracy. 38 Wf2 .:d3 Of course, the king must not be a l lowed to go to e3. 39 a4 c3 39 . . . .l:ixh3? would have lost: 40 l:!.c5 l:!.b3 4 1 .l:ixc4 .l:ixb2+ 4 2 We3 . After the inevitable fa l l of the e4-pawn White ach ieves an ideal construction - his rook defends both pawns along the 4th rank , not a l lowing any counterplay. The king can calmly approach the a-pawn. There was also the interesting move 39 . . . Wf7 with the idea after 40 .l:ic5?! 'i.t>e6! of supporting the passed e-pawn with the king . 40 a5 c3 4 1 b4 ! is stronger (but not 4 1 bxc3 .l:ixc3 with a draw). After 4 1 . .

On the last move before the t ime control Jan Timman makes a decisive mistake.

The 1998 No. 5-6 issue of the magazine Shakhmaty v Rossii published an extensive article by Alexey Kuzmin, in which the grandmaster pointed out a number of mis takes in the analysis of the Yusupov Timman ending. It turns out that 40 ... e3+ would not have saved Timman. White suc ceeds in breaking through decisively with his king: 41 ..ti>f3! 1hc3 42 l:!.e5 l:ta3 43 �f4! .!:!.xa4+ 44 �g5, and the resulting ending with two pawns against one is won. This means that there is no reason to criticise his choice on the 38th move. Moreover, the alternative 38 a4?! would in fact have thrown away the win. The variation considered by Yusupov - 38 ... 'iJ.d3 39 a5 c3 40 bxc3 e3 4 1 �f1 l:f.xc3 42 a6 .l:!.a3 43 l:!.b6 Wf7 44 g5 e2+ 45 Wxe2 11xh3 46 .l:tf6+ 'it>g7 4 7 .l:i.c6 �f7 48 �d2 l:!.g3 49 a 7 'iJ.a3 50 .l:!.c 7 + 'it'e6 51 Wc2 Wf5 52 Wb2 etc. is unconvinc ing. Instead of the incorrect 5 1 ... Wf5? Black should hold his ground: 5 1 ... �d6! 52 �g7 Wc5 53 �b2 l:f.a6 54 Wb3 .:ta1 , and White is unable to strengthen his position. He in turn could have successfully forced events ear lier: 4 1 a6! (instead of 4 1 �f1) 4 1 ... '1J.d1 + 42 Wg2 e2 43 a7 l:f.a1 (43 ... 'iig 1 + 44 �f3) 44 l:f.e5 l:f.xa7 45 l:f.xe2. But this happened only as a result of Black's mistake 40 ... e3?. According to Kuzmin's analysis, by playing 40 ... '1J.xc3! 4 1 a6 'iJ.a3 42 .l:!.b6 Wf7 43 h4 e3 he would have gained a draw. I n conclusion , here is a very compl icated , purely analytical end ing . Yusupov - Mestel Esbjerg 1 980 This interesting position with an unusual wh ite pawn configuration on the kingside arose immediately after the adjournment. Only a win offered me chances of taking fi rst place in the tou rnament and achieving the 56 c3 White has an extra piece in play - his k ing. This factor wi l l tel l , for example, if Black plays 'accord ing to the ru les' (but in fact routinely): 43 . . . .l:!.a8? - placing h is rook behind the passed pawn . In this case there fol lows 44 l::td2, then .l:!.a2 and 'it>xc4, and the a-pawn wi l l be lost. Black cannot defend in this way - he is clearly too late with his counterplay. The best chance was 43 . . . e5! . Jonathan Mestel d id not play this , because he was afra id of 44 .l:td2 'i¥te6 45 'it>xc4 . But after 45 . . . .l:i.c8+ 46 'it>b5 l:ta8!

As a rule, the necessary basic knowledge is made up of a small number of rather s imple positions, but they must be understood in every deta i l and fi rmly remembered . A successfu l ly developed system of basic endgame knowledge provides a rel iable guide in the analysis of more compl icated situations and helps them to be more successfu l ly understood . How this occurs , I wi l l show using an example of endings with opposite-colou r bishops. Connected passed pawns Let's d iscuss in detai l the fol lowing elemen tary ending. after a bishop check) , then 'it>e5 and f5-f6 . I n order to counter this p lan , B lack must take control of the e6-square. But from where , d 7 or b3? We wi l l consider both poss ib i l it ies. After 1 . . . i..b3? the position is lost. F i rst Wh ite g ives a verifying check with his bishop, i n order to determine the position of the enemy king . I n so doing it is important that the bishop should prevent the king from wedging itself between the pawns after White plays e5-e6. Hence , 2 i..g5+ ! . Next the white king makes a by-pass manoeuvre to the aid of the e-pawn, on the opposite side to where the oppo nent's king has moved. For example: 2 . . . 'it>f7 3 'it>d4 i..a2 4 �c5 i..b3 (4 . . . i..b 1 5 e6+ and 6 f6) 5 �d6 and 6 e6+ . Or 2 . . . 'it>d7 3 �f4 i..a2 4 i..h4 i..f7 5 �g5 �e7 6 �h6+ �d7 7 �g7 i..c4 8 'it>f6 and 9 e6+ . After the pawns have reached e6 and f6 , even if the threat of f6-f7+ is parried , Wh ite repeats the same procedure : a verifying check with the bishop and a by-pass by the king . It is incorrect to play 2 il.b4+? �f7 ! (Black's only hope is to provoke a prematu re e5-e6+ and wedge h is k ing between the pawns) 3 �d4? i..c2 ! 4 e6+ �f6 5 e7 i..a4 with a draw. As soon as the pawns are blockaded on squares of the same colour as their bishop, the draw becomes obvious. Thus, with h is bishop on b3 Black loses. On the other hand , 1 . . . i..d7! 2 i..g5+ �f7 1eads to an easy draw. Subsequently B lack waits, moving his bishop between c8 and d7. I n order to prepare e5-e6 , Wh ite wou ld need Wh ite is threatening to play e5-e6 (perhaps to make a by-pass with his k ing from the left, From the Simple to the Complicated l2J 65 but this is impossible, s ince the king is tied to the defence of the f5-pawn. The fol lowing ru le suggests itself: the bishop should be positioned such that, while preventing the advance of one pawn, it simultaneously attacks the other. We wi l l use the ideas from the basic position just examined for an analysis of other positions. F i rst some comparatively s imple ones. Let us sh ift a l l the pieces one rank forward . What has changed? After a l l , with the king on f8 White's only plan - a by-pass with the king from the r ight - is impossible: the edge of the board prevents it. But it is Wh ite to move , and he shuts the opponent's king in the corner by 2 .il..c4 ! and then carries out the standard manoeuvre - the by-pass with the king from the left: 'it>h5- g4-f5-e6-f7. After 1 . . . if..f8 ! the by-pass is no longer possib le , but what about the threat of zugzwang? I n order to put the opponent in zugzwang, Wh ite must deprive the king of the g8-square by playing 2 if..c4. But after In the event of 1 . . . .i.b4 there is no d iffer- 2 . . . .i.xh6! 3 �xh6 th ings end in sta lemate . ence . White wins in exactly the same way (a check and a by-pass by the king); moreover, here , as it is easy to see , both checks at b6 and b5 are equal ly good . After 1 . . . .1i.d8 2 if..g6+ (or 2 .i.b5+) 2 . . . �f8 3 Wf5 Black loses because of zugzwang - in contrast to the previous position , he no longer has a waiting move with h is bishop. (see diagram) The proximity of the edge of the board introduces new features into the evaluation of the position . Let us verify 1 . . . if..b2. I f B lack could also manage to play 2 . . . Wg8 and 3 . . .'it>f8 , the draw would become obvious . I n a l l the situations examined earl ier the 66 � From the Simple to the Complicated weaker side was a 1m1ng to g ive up h is bishop for the two pawns . Here, of course, this fami l iar plan of defence wi l l no longer save him. Does this mean that B lack is doomed? It turns out that he is not - wing pawns can sometimes be stopped without resorting to the bishop sacrifice . 1 . . . i.d1 ! 2 �h4 (otherwise g4-g5 cannot be played ) 2 . . . � 3 g5 �e6! 4 g6 'itf5!

And if 5 g7, then 5 . . . .ib3 and 6 . . . .ig8 , with a secure l ight-square blockade of the enemy pawns. The fol lowing example is much more d iffi cult. M. Henneberger 1 9 1 6 The black bishop i s not i n its best position (the place for it is at e7 or dB). In the basic theoretical position , with which we began , against such a bishop White won easi ly. I f we reason logical ly, on ly one factor, d istin guishing the g iven posit ion from the basic one, can prevent the implementation of the standard winning plan - the proxim ity of the edge of the board . Let us see! 'Accord ing to the ru les' Wh ite should give a check on h5 , to control the g6-square . The black king should move to e7, forcing the wh ite king to make a by-pass to the right, where there is l i tt le space for manoeuvring. 1 i.h5+ �e7! (after 1 . . .

Even so , t he resources for playing for a win are not yet exhausted .

Let's set it up with colours re versed , so that it wi l l be easier to draw an analogy with ideas that are a l ready known to us . The wh ite b ishop occupies an ideal position , whereas on the h3-c8 diagonal the black bishop is not it its best place. Without the e2- pawn the win would not be i n doubt, but here White constantly has to reckon with the threat of the d ivert ing sacrifice . . . e2-e1 'ii', after which for an instant the bishop loses control of important squares in front of its pawns. The question is whether or not Black is able to make use of th is resource . 68 w From the Simple to the Complicated 1 �e3 Threatening both the capture of the e2- pawn, and the march of the king to f6 . After 1 . . . il..g4 (1 . . . il..h3? 2 �xe2) 2 �f4 B lack is unsuccessfu l with 2 . . . e 1 'ik 3 il..xe1 il..h5 (with the threat of 4 . . . il..f7 ) 4 e6+ �d6 5 �e4, whi le if 2 . . . il..h3 3 �g5 e 1 'ik 4 il..xe1 il..g2 , then 5 e6+ �d6 6 il..b4+ �xd5 7 e 7, and the pawn queens. But what else can he do? 1 . . . �c7 ! ! The key idea of B lack's defence! I t i s important that the pawn should not advance to e6 with check (for example, after 2 �xe2 Si.e4 ). Without the e2-pawn White would reply 2 e6, but here this leads to an immed iate draw: 2 e6 il..xe6 3 dxe6 e 1 'ik 4 il..xe1 �d6 (Black's moves can also be interposed) .

F ina l ly, after 2 il..a5+ �d7 3 �f4 the main defensive idea in such endings proves possible - the switching of the bishop to f7 : 3 . . . Ji.g6! and 4 . . . il..f7 (4 e6+ ct>d6) . After moving the pieces around for a short whi le, we decided that the endgame was drawn and hence that Timman's study was incorrect, s ince it conta ins a second solu tion . Later, when I was on my own , I again set up the pieces and found another attempt to play for a win , based on zugzwang. 2 il..e1 'it>d7 3 il..a5!

As you see, the analysis proved to be rather difficult, and fu l l of by no means obvious manoeuvres by both sides. But even so, at the basis of the analysis were ideas which we derived from the basic theoretical posi tion . Separated pawns General ly speaking , the further apart the pawns are, the more d ifficult the defence. When I was young I learned a humorous rule for assessing such endings: if you can reach both pawns with the fingers of one hand , then the position is d rawn ; if you can't (the distance between the pawns is too great) the position is won ! Alas, such a gu ide is too imprecise to be trusted . In fact, here there exist many different situations which it is not at a l l necessary to study and remember. The outcome usual ly depends on the possibi l ity of a breakthrough by the stronger side's king to the pawn being stopped by the bishop, i n order to queen it. But the fol lowing ending should defin itely be included in our system of basic knowledge.

Averbakh 1 954 I n the fi rst edition of the monograph on chess endings ed ited by Averbakh, the analysis of this endgame conta ined a seri ous mistake - it was d iscovered by Yusupov, when I i nvited h im to try and solve th is position . However, Averbakh h imself cor rected the mistake in a subsequent ed ition . 1 'it>c3 i.f1 2 'it>d4 .lte2 3 �e5 'it>d7 Now it is wrong to play 4 'lot>f6 i.d3 5 a6? i.xa6 6 �xg6 'it>e8 , when the fami l iar Berger-Kolterman ending is reached (with reversed colours) . The correct plan is to p lay for zugzwang. From d3 the bishop defends the g6-pawn along one d iagona l , and along the other it prevents the advance of the a-pawn ; there fore it has no moves. The wh ite king must not be al lowed to reach e 7 - this means that, apart from d7, the black king also has two other squares: e8 and d8. The first can be taken away from it by placing the white king on f7, and the second by moving the bishop to c7. 4 .ltc5 i.f1 5 i.b6 .te2 6 .tc7 i.d3 7 'it>f6 'it>e8 8 'it>g7 'it>d7 9 'it>f7 , and Black is i n zugzwang.

This means that the working methods described in this book have stood the test of t ime. I hope that they wi l l a lso prove su itable for you . 8 PART I Endgame Theory Mark Dvoretsky How to Study the Endgame Many young players 'flounder' when it comes to playing endings. They would not be averse to improving their endgame mastery, but they don't know exactly how to do this. I n chess l iterature practica l ly noth ing is said about methods for the independent study of endgame theory. We wi l l now endeavour to partly fi l l this gap . Two main ways of improving in the endgame can be d isti ngu ished : I . The study of theory (development of erudition , en richment of the store of end game knowledge) . I I . Improvement in the genera l technique of endgame play. It stands to reason that these two d i rections are closely inter-connected , and progress in one of them invariably leads to progress in the other. However, let us nevertheless consider them separately. I . THE STUDY OF THEORY To expand your store of knowledge you need to make a systematic study of various types of endings. Here the tradit ional d ivi sion by material is qu ite appropriate. By successively examin ing , for example, pawn, kn ight and queen endings we ass imi late the specific featu res of these types of endgame. Al l endgame positions can be arb itrari ly d ivided into 'exact' and 'problematic' . Posi t ions which are fami l iar to us , i n wh ich we know beforehand the evaluation and correct plan of action , we cal l 'exact' . Note that they are fami l iar to us, and not to the theory of endings in genera l . Different players have d ifferent stores of exact positions. Al l rema in ing positions belong to problem atic. I n them we do not demonstrate our knowledge, but fight, seek the best moves , and ca lculate variations - in short , we play. A na"ive opin ion is prevalent, identify ing the mastery of endgame theory with a knowl edge of numerous exact positions. But is a large store of specific knowledge real ly necessary? After a l l , exact positions (apart from the most elementary) occur rather rarely in practice . More often a player has to fig ht in problematic situations. He should study the general endgame laws which apply in them and the most common regu larities, p laying methods and typical evaluations . Al l this, together, of course, with the most important exact positions , is what comprises the integra l system of our endgame knowledge. I must once again emphasise: the store of positions which you need to know exactly is How to Study the Endgame CLJ g comparatively smal l . Only in rook endings do you need to have a fi rm knowledge of several dozen specific positions; in other types of endings - much fewer. When studying them it is often not necessary to delve into compl icated analyses - it is sufficient merely to remember the main conclusions. Take, for example, rook endings with f- and h-pawns. They occur qu ite rarely, but never theless they do occur, so that it would be useful to obta in some impression of them. However, i t is hard ly advisable to study the entire theory of this type of endgame - it is just too compl icated . What, then , from this theory should the practica l player add to his armoury? Above a l l , the information that such endings are normally d rawn . I t is usefu l to examine a practical ending , demonstrating the main defensive ideas. Gl igoric - Smyslov Moscow 1 947 The black rook is excel lently positioned on the 5th rank , preventing the wh ite king from advancing.

We now know where Black should place h is rook. And the king, as was shown by l lya Maizel is , is best kept at f7 unti l there is a danger of it being driven onto the back rank . Then i t can stand at g7 and subsequently even at h6, attacking the wh ite pawn. I t stands to reason that by no means a l l positions with f- and h-pawns are drawn . The most important exception has a l ready been mentioned several times - when Black's king is cut off on the back rank , he normal ly loses. 1 f6 l:!.a1 2 l:l.g7+ 'it>h8 2 . . .

Endings with many pawns After studying for many years the theory of endings with opposite-colour bishops, I observed several ru les which , as it tu rned out, apply in nearly a l l such end ings and greatly help in confidently find ing your way in them. Before tu rn ing to a description of my theory of endings with opposite-colour bishops, I wi l l show an example i n which , despite its s impl icity, nearly a l l the rules that we wi l l be ta lk ing about are d isplayed . From the Simple to the Complicated 71 Textbook example If it is White to move he saves h imself by 1 c5! i..xc5 2 �b3 e5 3 �e6 'l,;c7 4 'it>e4. Later he s imply p lays h i s bishop up and down the h3-c8 d iagona l . 1 . Drawing tendencies. This i s perhaps the best-known property of endings with opposite-colour bishops. Here it is some times possible to save the game when you are 2-3 pawns down (as, for instance , i n the example just examined ) . And remember the endings with two connected passed pawns - in what other type of endgame may such an enormous material and positional advan tage prove insufficient for a win? The consequences of this rule a re obvious : the stronger side should be extremely careful both when transposing into an ending with opposite-colour bishops, and when playing such an ending - here it is easy to run into a drawing counter chance. And for the weaker side, trans posing into an ending with opposite colour bishops is sometimes a last resort - here the chances of a draw are sharply improved. I I . Fortress. A fortress is a system of passive defence, consisting in the construe- tion of an impregnable position , in which it is sufficient to stick to wait ing tactics since everything is securely blockaded and de fended . The main theme in endings with oppo site-colour bishops is the theme of the fortress. The weaker side aims to con struct a fortress, while the stronger side aims to prevent its construction or (if it has already been constructed) find a way of destroying the opponent's defences. I n the textbook example the conclud ing position constitutes a fortress. Wh ite does not seek any active counterplay, but s imply wa its , and the opponent is u nable to do anyth ing . When playing end ings , an abi l ity to analyse positions logical ly, by th inking in p lans and schemes, is very important. The role of logical th inking is especia l ly great in endings with opposite-colour bishops. In the majority of cases they should not be 'p layed ' , but 'constructed' - fi rst look for the arrangement of pieces and pawns which makes the position impregnable, and only then verify by calcu lat ing variations whether it is possi ble to achieve the p lanned set-up and whether it is i ndeed impregnable. The fol lowing mechan isms constitute either the most important genera l methods of constructing and destroying a fortress , or featu res of the most typical and frequently occurring types of fortresses. I l l . Arrangement of the pawns. There is a wel l-known principle which prescribes that pawns should be placed on squares of the opposite colour to those on which you r own bishop moves. In endings with opposite colou r bishops th is pr inciple remains val id for the stronger s ide ( it is especia l ly impor tant with regard to connected passed pawns). But, contrary to the general rule, the weaker side should keep his pawns on From the Simple to the Complicated squares of the colour of his own bishop - in this case it is usual ly possible to ensure that they are securely defended . I ndeed , a pawn defended by the bishop can be attacked only by the enemy king , wh ich means that it remains invul nerable. In other types of endings such a pawn may be attacked not only by the king, but a lso by another piece (knight or l i ke-colour bishop) . I n the textbook example the weaker s ide's pawn is on a l ight square - the colour of its own bishop, and this factor ensures the sol id ity of the fortress constructed by White . I n the in it ial position the stronger side, with his dark-square bishop, has only the one pawn on e6 correctly placed on a l ight square. If B lack were able to approach it with his king , he would then play . . . f6-f5 and easily convert h is materia l advantage. The only way to draw is to force the e-pawn to move onto a square of the colour of its own bishop. IV. Nuances in the position are more important than material . I n endings with opposite-colour bishops the number of pawns on the board is often of far less importance even than seemingly insign ificant changes in the placing of the pieces or pawns. Therefore in endings with opposite-col our bishops, positional pawn sacrifices constantly occur. Thus in the textbook example Wh ite happi ly sacrifices a th ird ( ! ) pawn in order to achieve a 'trifle' - sh ift the black e-pawn one step forward . V. Principle of one diagonal . Both for the stronger, and the weaker side it is very important that the bishop should defend its own pawns and restrain the enemy pawns 'without being torn', along one and the same diagonal. In the concluding position of the textbook example the bishop on the h3-c8 d iagonal defends the h3-pawn and stops the two enemy pawns on f6 and g5. But in the Averbakh position analysed earl ier the bishop defends the g6-pawn along one diagonal and restra ins the passed a5-pawn along another. Such a situation is unfavourable for Black. In the solution and the false trail you saw two typical ways of exploiting the defects of a 'torn ' bishop: zugzwang and diversion. VI. Pawns 'under attack' . A typical defensive procedure is an attack on the opponent's pawns by the bishop. I n th i s way either they are forced to move onto less favourable squares of the colour of their own bishop (as in the textbook example) , or the opponent's king is tied to the defence of the pawns (as in the basic position with two connected passed pawns or the Berger Kolterman ending) . End ings very often occur where the stronger side has a passed pawn . I t must be blocked by the king (fi rst system of defence) or the bishop (second system of defence) . VII . F irst system of defence - the weaker side's king blocks the opponent's passed pawn , and the bishop defends its own pawns. This is the basic and usual ly the most rel iable method of defence. Attempts to destroy the first system of defence always involve creating a sec ond passed pawn, often by means of a pawn breakthrough. VI I I . Second system of defence - the bishop stops the passed pawn (or some times two , along the same d iagona l ) , whi le the king , expressed in footbal l language, engages i n 'zonal defence' - it protects its pawns and restricts the activity of the opponent's k ing . Attempts to destroy the second system of defence always involve breaking From the Simple to the Complicated ttJ 73 through with the king to its passed pawn (sometimes after a preparatory diver sionary attack on the opposite wing). We wil l now do some tra in ing in the employment of this theoretical foundation for the analysis of specific endings. We wi l l try t o approach them in a logical way: we wi l l point out which system of defence has been employed or should have been employed by the weaker side and in what way it may be possible to try and destroy this fortress, whether the pawns are correctly placed , whether it isn 't possible to put the oppo nent's pawns 'under attack' , whether, in order to carry out some idea, it is possible to sacrifice a pawn or two , and so on . Fuchs - Kholmov Dresden 1 956 Black wi l l probably obta in a passed pawn on the queenside, but itwi l l be blockaded by the opponent's king (fi rst system of de fence). The only winn ing chance is to create a second passed pawn . For this B lack needs to play . . . f7-f6 , . . . 'it>f5 and g6-g5, then exchange on h4 and win the h-pawn. In t he game Ratmi r Kholmov successfu l ly carried out th is p lan and won . I n a book h e wrote on the endgame, N ikola i Krog ius considered th is outcome to be perfectly logica l . I n fact the position is , of course , d rawn - this is clear at fi rst g lance, it being sufficient only to remember the draw ing tendencies with opposite-colour bish ops. How can one expla in such a bad mistake in eva luation , made by a player who at one t ime was qu ite a strong grandmaster? I n my view, by a change of profession : one by no means fine day Krog ius decided to ' re qual ify as a manager' , fi rst in h is native Saratov, and then in Moscow - he became head (and , it should be mentioned , a very nasty head ) of the Chess Admin istration of the USSR Sports Committee . Apparently Caissa is a jealous woman who seeks vengeance when she is betrayed . 43 . . . f6! 44 'it>d2 White's objective is to defend the kingside with h is bishop and not a l low the opponent to create a second passed pawn there. For the moment the move in the game does not yet spoil anyth ing , but it was simpler to play 44 d5! 'it>xd5 45 'it>d3(d2) fol lowed by i.e3- b6-d8 (the f6-pawn 'under attack' ) . The d raw would then be obvious - after moving h is k ing to f5 and playing . . . g6-g5 , B lack would be u nable to make any further progress. 44 . . . 'it>f5 45 .if4? Now the opponent inevitably obta ins a passed pawn on the kingside. Meanwh i le the 'pawns u nder attack' procedure cou ld a lso have operated successfu l ly here: 45 .ih6! g5 (45 . . . '1t>g4 46 .ig7 f5 47 .ih6 or 47 d5) 46 i.g7 ! , preventing 46 . . . '1t>g4 . 45 d5! i.xd5 (45 . . . g5 46 d6 i.c6 47 .id4) 46 i.d4 or 46 i.b6 g5 47 .id8 was a lso good . I t is evident that procedures in the playing of endings with opposite-colour bishops, such 74 � From the Simple to the Complicated as the sacrifice of one's own pawns or attacks on the opponent's , were unknown both to the national master Fuchs, and to grandmaster Krog ius. 45 . . . 46 i.c7 47 i.d8 48 gxh4 49 i.xf6+ 50 'it>e3 51 i..e7 g5 'it>g4 gxh4 'it>xh4 'it>g4 i.d5 b5 White resigned - in the opin ion of Krogius , because of the variation 52 i..d8 h4 53 f3+ i.xf3 54 'it>f2 h3 fol lowed by the switching of the king to the queenside (on the h3-c8 d iagonal the black bishop defends its own pawn and restra ins the wh ite d-pawn) .

And yet White's 45th move was a funda mental mistake: instead of find ing and erecting a secure fortress, he a l lowed the opponent to compl icate the play advanta geously. Bogoljubow - Ed. Lasker New York 1 924 White should win thanks to h is powerfu l pair of connected passed pawns. I t was s implest to bring the king to the centre : 36 �f2 . Apparently Efim Bogoljubow was striving to play as safely as possible - he wanted to prevent . . . a7-a5 and with this a im he decided to exchange the rooks.

Remember the need to exercise caution when transposing into an ending with oppo site-colour bishops , in view of the inherent d rawing tendencies.

The sacrifice of a pawn is a common phenomenon in end ings with opposite colour bishops. 38 axb4 39 d4 i.a6! i.d3! This is a lso a standard defensive procedure - an attack on the enemy pawns.

Taking into account the principle 'nuances in the position are more important than mate ria l ' , we should a lso check 38 'it>f2 !? ( instead of 38 axb4 ) , in order not to a l low a blockade of the central pawns. However, after 38 . . . bxa3 there is no win for White - the a-pawn diverts the bishop from its control of the squares in front of the connected passed pawns.

I wi l l merely show one way (I would not assert that it is the only one, but in my view it is the s implest) of ga in ing a draw.

Grandmas ter Igor Khenkin was afra id that the end game was lost, s ince White has two extra pawns. I n fact it is a s imple draw, and in establ ish ing th is we are helped , apart from the genera l gu ide ( 'drawing tendencies' ) by a qu ite specific one. If Wh ite g ives up h is g3- pawn, we obta in the wel l-known d rawn situation from the Berger-Kolterman game. But if he advances it to g4, Black rep l ies . . . g6-g5, and blocks all the enemy king's approaches to the upper half of the board . Here is an approximate variation : 47 �xh3 �6 48 �g4 ii.d6 While there is t ime, it is usefu l to force the opponent's pawn to stand on a square of the colour of its bishop. 49 b5 i..c7 50 �d5 ri;e7 76 � From the Simple to the Complicated 51 �c6 52 �f3 53 g4 54 'it>e3 55 �d3 56 �c4 f6 �e7 g5 �b6+ 'it>d6 �e5 The draw is obvious - there is nowhere for the wh ite king to break through . Vakhidov - Timoshchenko Tashkent 1 982 For the moment B lack is not threatening to play 1 . . . g3 in view of 2 g5! and 3 �g8 - he is plann ing 1 . . . g5! and only then 2 . . . �g3. Now White has to decide how he wi l l defend his kingside pawns and which piece wi l l hold back the enemy passed pawn on the queenside. In the game he chose the fi rst system of defence: he switched his bishop to the defence of hispawns, and kept his king on the queenside. 1 .i.b3 g5! 2 .i.d1 2 h4 gxh4 3 g5 does not work: 3 . . . �g3!

But the bishop is real ly very passive soon it wi l l not have a single waiting move. If the king can a lso be deprived of its mobi l ity, a zugzwang situation could result . This aim, strangely enough , is qu ite ach ievable: the wh ite king is g radual ly pushed to b3 and the black king wi l l occupy the d3-square , from where it continues to tied down the oppo nent's bishop and at the same time threat ens to support its passed pawn . But if the pawn were sl ightly further away - on the a fi le - a d raw would become inevitable. 5 ..td1 'it>g3 6 �f3 'it>f2 7 'it>c2 b4 8 �b3 ..tc3 9 �c4 h6 1 0 �d3 ..te1 1 1 �c4 ..td2 12 �d3 �c3 (zugzwang ! ) 1 3 �c4 �e3 (again zugzwang! ) .

Now let us try to set up the second system of defence - use the king for the defence of the kingside. But this plan too is not a ltogether rel iable - after a l l , the bishop wi l l have to perform two tasks: not only conta in the enemy passed pawn , but also defend its own e4-pawn , and along a d ifferent d iago na l . This means that here too a zugzwang position is qu ite l i kely. 1 ..td5 g5! 2 'it>e2 h6 3 ..tb7 ..tc5 4 ..td5 a6 5 ..tc4 (5 ..tb7 b5 6 a5 b4 7 ..txa6 �xe4 is no better) 5 . . . b5! 6 axb5 a5 (Black happily sacrifices a pawn for the sake of creating a passed pawn ) 7 ..td5 a4 8 ..tc6 a3 9 ..td5 ..tb6.

Is the in it ial position rea l ly lost for White? Let's use our knowledge of opposite-colour bishops to guess where a saving l ine might nevertheless be concealed . First of al l one should usual ly check the basic system of defence - the fi rst . But how to securely defend the kingside with the bishop, and prevent there the creation of a second passed pawn? The manoeuvre of the b ishop to f3 solves this problem , but it inevitably leads to zugzwang. I s there no other way? Remember the procedure 'pawns under attack' and for the sake of implement- ing it let us be prepared to sacrifice a pawn ! 1 g5! ! �xg5 2 ii.g8! h5 2 . . . h6 comes to the same th ing . 2 . . .t>f6 3 �c4 also does not achieve anyth ing . 3 ii.f7 h4 4 'it>c4 The d raw is obvious, s ince now the bishop easily copes with the defence of the king side.

I n conclusion I offer a few exercises , in the solving of which you wil l tra in yourself in the practica l appl ication of your theoretical knowledge.

Nimzowitsch-Tarrasch (Kissingen 1 928). Black must decide how to combat the threatened attack by the king on h is kingside pawns. The 'active' 39 . . .f4? is hopeless: 40 Jl..g5 e3 (40 .. .f3 41 g4) , and Wh ite has a pleasant choice between 41 fxe3 and 4 1 f3 e2 42 Ji..h4 fol lowed by �g 1 -f2 . F i rst let us see what happened in the game. 39 . . . c4? Moving the pawn onto a square of the colour of its own bishop is , in genera l , a sound positional idea ( imaginethat White were to play c2-c4 , b2-b3 and a2-a4 - then the b6· pawn would be transformed into a serious weakness) . The move made by Black is not bad in itself, but for the reason that it does not help to solve the main problem of the position - the defence of the kingside pawns. 40 'it>g3 �c8 41 'it>f4 'it>d7 42 j;_b4 �e6 43 Jl..c3 Ji..d7 I f Black keeps his bishop at g6 and uses his king to stop the future passed pawn on the queenside (fi rst system of defence) , at an appropriate moment White will attack the bishop by h3-h4-h5 and obta in a second passed pawn. For example, 43 . . . ii.g6 44 g5 �d5 45 g3 b5 46 h4 �c6 4 7 b3 cxb3 48 cxb3 'it>b6 49 a4 bxa4 50 bxa4 'it>a6 51 a5 �b5 52 h5 ii.e8 53 �xf5 ii.xh5 54 �xe4 with an easy win . Therefore Black leaves his bishop on the queenside. Unfortunately for h im , h is king cannot s imultaneously defend the h7- and f5-pawns, and therefore his bishop wi l l be 'torn' between the defence of the f5-pawn and the struggle against the opponent's passed pawn . 44 g3 b5 45 �g5 �f7 46 h4 Jl..c8 47 �h6 �g8 48 b3 cxb3 49 cxb3 f4 This is a l ready desperation in a hopeless position .

From the Simple to the Complicated 4J 81 As usual , we shou ld fi rst look for a possib i l ity of setting up the fi rst system of defence - leave the king on the queenside and ensure the defence of the pawns by the bishop.

Therefore it is usefu l to be able to evaluate them quickly and accurately. The winning plan is obvious: march the king over to the rook's pawn . The opponent has to e l iminate the pawn on the other wing and then rush with his king to the corner, in order to stop the rook's pawn . I n which cases does he manage to do this? Here White wins: 1 'it>d5 'it>f6 2 'it>c6 'it>xf5 3 'it>b6 'it>e6 4 'it>xa6 'it>d7 5 'it>b 7. Now let us shift the queenside pawns back by one rank. I t is easy to see that the position has become drawn : 1 '>t>d5 'iM6 2 'it>c5 'it>xf5 3 'it>b5 '>t>e6 4 'it>xa5 'it>d7 5 'lt>b6 '>t>c8. I f, say, the kings and the f-pawn are sh ifted one rank down or to the left, Black again loses . But what happens if the queenside pawns are a lso sh ifted down? Of course, if you have the position in front of you , it is easy to g ive an answer to any such question . But i n practice such situations often arise at the end of lengthy variations, which you have to calculate , and to lengthen the calculation by several more moves may prove d ifficult. I t would be desirable to learn to determine the evaluation of the position immed iately, on fi rst looking at it. A s imple method of rapid evaluation was suggested by Walther Bahr in 1 936. To me this ru le seems not a ltogether conven ient, and besides it does not extend to cases where the king is not to the side of the passed pawn , but in front of it. I n connection with th is I should l i ke to offer a somewhat The Arithmetic of Pawn Endings lLJ 83 different method of rapidly eva luating such positions. 1 ) The fi rst rule coincides with Bahr 's analogous ru le : if the rook's pawn of the stronger side has crossed the middle of the board, the position is always won. It follows that from a s ingle g lance at the fi rst diagram it may be concluded that the position is won . 2 ) We wil l ca l l the position in the second diagram 'norma l ' . This is what makes i t such : a) between the queenside pawns there passes the invisible demarcation l ine , sepa rating the upper and lower halves of the board ; b) the black king , which is a iming for the c8- square, reaches there without loss of time. Th is happens because the passed pawn has already crossed the key h3-c8 d iago nal , or is on this d iagona l . A 'normal' position is drawn. 3) Each sh ift ing of the kingside pawn one square down from the h3-c8 d iagonal is equivalent to a tempo in favour of White . For example, the pawn on f4 g ives one tempo in favour of White , and the pawn on e4 g ives two. One further tempo for the stronger side may be given by having h is king not to the side of the passed pawn, but in front of it . But each shifting of the queenside pawns one square down compared with the 'nor mal ' position g ives the defending side a tempo. With the pawns on a3/a4 B lack has one tempo in h is favour, and with the pawns on a2/a3 he has two . White wins only if the sum of tempi, calculated in this way, is in his favour. The formulation suggested by me looks rather compl icated and cumbersome, but if you learn it thoroughly you will find it very easy to use. With White to move , it is a win : 1 a5! (the pawn has crossed the middle of the board ) . With B lack to move , i t is a d raw: 1 . . . a5! , and a 'normal ' position arises. Wh ite wins: he has two tempi (the g2-pawn is two squares lower than the g4-square) , whi le B lack has only one. But if the queenside pawns are sh ifted down one rank , the score becomes 2-2 and the position is now d rawn . 84 \t> The Arithmetic of Pawn Endings Here, of course , it is White to move (with Black to move he has to concede the opposition and White can queen his f-pawn) . Wh ite wins, s ince the score is 3-2 in h is favour (two tempi are g iven by the pawn on f3 and another one by the position of the k ing in front of the pawn) . He wins by 1 'ite4! 'ite6 2 'itd4(d3). It would be a blunder to play 1 'ite3? 'ite5(f5) , s ince then a position with a tempo ratio 2-2 is reached (the wh ite king is no longer in front of the pawn , but to the side of it) , and this means a d raw. One more usefu l deta i l . Let us suppose that White's passed pawn is a rook's pawn , and his k ing is in front of it , but the enemy king is confin ing its opponent to the h-fi le . This situation is equivalent to the one in which the king is to the side of the pawn. Accord ing to the afore-mentioned ru le, this should be a d raw. And i ndeed : after 1 . . . �5 2 'ith5 (2 'itg3 'itg5 - a 'normal ' position) B lack does not play 2 . . . 'iii>f6? 3 'itg4, when White acqu i res an extra tempo, since his king is in front of the pawn , but 2 . . . 'itf4! 3 h4 (3 'itg6 'itg3) 3 . . . 'itf5 4 'ith6 'itf6 5 �h7 'itm(f5) 6 h5 'itt6 ! etc. Now let us examine some more compl icated endings, i n which a mastery of the rule suggested by me sign ificantly eases the calculation of variations. Privorotsky - Peterson Riga 1 967 Black's positional advantage is obvious. His p lan is clear: . . . 'itg6-f5-e4 and then an attack by h is bishop or king on the queenside pawns.

The only way! Otherwise Black h imself would have played 8 . . . h4! , then picked up the a3-pawn and won , s ince his pawn on the other wing has crossed the m iddle of the board . But after the move in the game a 'normal ' position arises, and th is means a draw. 8 . . . 9 'it>d3 10 'it>c3 'it>b3 'it>xa3 We have reached the last of the textbook examples that we analysed .

I f White does not evaluate them ' mechani cally' , by using the ru le g iven above , but tries to work out the variations to the end, he each time has to calculate some ten more moves, and this is not at a l l easy. The players in the fol lowing ending faced even more compl icated problems. Matanovic - Botvinn ik Belgrade 1 969 In h is notes Mikhai l Botv inn ik analyses two courses of action for Wh ite : 43 .l:td5 and 43 l::td6+ 'it>e7 44 l:f.a6.

After studying it you wi l l have a better understanding of the theory of rook endings with connected passed pawns. Zlotnik - Vulfson Moscow 1 983 The adjourned position ; it is my move . The national master Anatoly Donchenko sug gested an excellent idea for Black. Usual ly with an advantage you are recommended to avoid pawn exchanges, but this is an exception to the ru le. 1 . . . g4! Black wants to tie the enemy rook to the defenceof the g3-pawn . 2 l::th4 is obviously hopeless, and therefore I stud ied , in the main , 2 hxg4 .l:i.xg4 . Things are difficult for White : noth ing is g iven by 3 .l:i.h6+ l:i.g6, and so he is forced to play 3 l:th3, but here the rook is exceptional ly passive . But here Boris Zlotnik unexpectedly made a move which I had overlooked in my analysis. 2 'it>b2 The idea is clear - to avoid the capture of the g3-pawn with check. The move is an interesting one, and duri ng the game it seemed to me to be very strong . But after a thorough analysis I began to have doubts about its strength . The point is that when Black e l iminates the g-pawn and obta ins a position with connected passed pawns, the basic method of defence is to try and wedge the king between the pawns and blockade them. But here the king , in solvi ng a partial problem ( involving the g3-pawn), voluntari ly moves away from the queenside pawns. 2 . . . 3 �xh3 4 l::th8 gxh3 .l::tg4 With h is rook on h3 White , natural ly, cannot hope for success, and so he activates it. Typical Endings with Connected Passed Pawns CZJ 89 Black's reply is forced , s ince if 4 . . . .Uxg3? there fol lows 5 .l::!.a8 with an immed iate d raw. 4 . . . aS Passed pawns must be pushed . S .l::!.c8 Aga i n it is not possible to capture on g3 because of 6 .l:!.c6+ fol lowed by 7 l:tc5 . I a lso reckoned with 5 .l:!.a8 , to force one of the pawns to advance and a l low the king more quickly to wedge itself between them. But I th ink that in this case too White would not have been able to save the game. 5 . . . .l:f.g5 The rook defends the pawns from the side. I n such situations this is the best place for the rook . Now the black king is free to go where it wants. 6 g4!? Now the capture of the pawn leads to a typical drawn position with connected passed pawns , one which occurs qu ite often : 6 . . . .!::!.xg4? 7 .l:!.c6+ rJ; e 7 8 .l:!.c5 l:tb4+ 9 'itta3 a2 . Black cannot strengthen h is position , since his king has n o shelter from the side checks. 6 . . . �e6? 6 . . .cj;>e5! suggests itself. Why d id I reject th is move? The reason was a psychological one. My opponent was the national master Zlotn ik , a chess teacher in the I nstitute of Physical Cu lture . I g reatly respected h im , and to me he was an expert. When you play such a person , a defin ite complex appears , you beg in to fear everyth ing , and therefore i t can be d ifficult to make an active move. Besides, I did not consider that the position was one where every tempo counted , I thought my king would a lways be able to go over and capture the g4-pawn , and for the moment it would not be bad to help the queenside pawns . What would have happened after 6 . . . rJ;e5 ? Let us try to provoke the advance of one of the pawns: 7 l:!.a8 . Black repl ies 7 . . . a4 , and if 8 �a3(c3) , then s imply 8 . . . .l:txg4. The king has not managed to reach b4 and after 9 l1b8 l1g3+ 1 0 �a2 .l:!.b3 Black wins. I f 8 �b8 ( instead of 8 �a3) , then 8 . . . �d4 9 �a3 �c5 1 0 lk8+ �b6 1 1 llb8+ �c6 1 2 lk8+ �b7 and 1 3 . . . I:txg4 with a win . The fact that his king is cut off along the 6th rank does not concern Black - his rook wi l l free the king by . . . l:tc4-c6 . Thus, 6 . . . 'it>e5 was a very good move, but I played differently. 7 l:tc1 White wants to place his rook behind h is passed pawn . 7 . . . �d6? 7 . . . �d5 was far stronger. 8 .l:f.g1 I should l i ke to dwel l on this position in more deta i l . (see diagram) White has succeeded in sign ificantly activat ing h is rook. If h is pawn were on g5 , he would undoubtedly be able to draw. But with the pawn on g4 h is rook has not so many squares for manoeuvring . Black now has two plans for playing for a win : 90 � Typical Endings with Connected Passed Pawns 1 ) play his king to the help of the queenside pawns; 2) fi rst capture the g4-pawn with the k ing, and only then return to the queenside. We wil l fi rst examine the simpler p lan , involving 8 . . . 'it>c5. I t is obvious that if Black can place his pawns on a4 and b4 he wil l win easi ly. Therefore White's objective is to hinder the advance of the pawns, lu re the rook away from g5 as soon as possible and begin advancing his passed pawn . First let us analyse 9 Wb3 . If 9 . . . b4 (with the threat of 1 O . . . 'i!i>b5) there fol lows 1 0 'it>a4 'it>b6 1 1 .l:!.f1 .l:!.xg4 1 2 .l:!.f5 ! with an immediate draw. Let us verify 9 . . . a4+ 1 0 'it>a3 'it>b6! 1 1 'it>b4 (preventing 1 1 . . . 'it>a5) 1 1 .. Jie5! . Against the threat of 1 2 . . . l:te3 White has two defences: 12 l:tg3 and 12 'it>c3 ( 12 'it>a3 .l:te2 is unsu itable, since the k ing remains in a mating net). After 1 2 .l:!.g3 .l:!.e4+ 1 3 'i!i>a3 'i!i>a5 (with the threat of 14 . . . .l:!.e2) 14 'i!i>b2(a2) b4 the black pawns reach their goal sooner than the g pawn . No better is 1 3 'i!i>c3 b4+ 14 'it>d3 a3! 1 5 'it>c2 .l:!.e2+ etc. Let us examine 1 2 'i!i>c3. Here the win for Black is not obvious. I n lessons devoted to the technique of converting an advantage, an important principle has been mentioned : to make use of any opportun ity to improve even slightly your own position and weaken the oppo nent's. Here Black can move his king forward , but in this case the wh ite pawn advances and there is no longer a win. The only way to the goal is to interpose the check 1 2 . . . .l:!.c5+ ! . If 1 3 Wb2, then 1 3 . . . .l:!.g5, and the b-pawn advances to the 4th rank. I n the event of 1 3 'it>d4 Black can either advance h is pawn immed iately, or fi rst play 1 3 . . . .l:!.g5 . There only remains 13 Wb4 l:tc4+ 1 4 'it>a3 . The d i rect 1 4 . . .a5? does not ach ieve anyth ing : 1 5 'i!i>a2 b4 1 6 g5 b3+ 1 7 'it>a 1 ! a3 1 8 g6 b2+ (for 1 8 . . . a2 and . . . 'i!i>b4-a3 Black is just one tempo short) 1 9 'i!i>b 1 Wb4 20 g7 'it>b3 2 1 .l:!.g3+ 'i!i>b4 22 .l:!.g 1 . The correct move is 1 4 . . . .l:!.c2! (with the threat of 1 5 . . . 'it>a5) 1 5 'it>b4 .l:!.b2+! (nothing is g iven by 1 5 . . . l:tf2 1 6 'it>c3 ; fi rst the position of the wh ite king must be clarified ) , and 1 6 Wa3 l:tf2 1 7 Wb4 .l:!.f3 is bad for White , while after 1 6 Wc3 there fol lows 1 6 . . . a3 1 7 g5 b4+ 1 8 Wc4 a2 1 9 lla1 ( 1 9 g6 .l:!.b1 ) 1 9 . . . b3 20 g6 l::tb1 21 g7.

[Nowadays, for the analysis of both opening and endgame positions, increasing use is made of computers. John Nunn and Graham Burgess checked the concluding position of this variation on a computer, and it tran spired that after 24 "YIVb8+ Black cannot avoid perpetual check. For example, with the king on h7 there follows 1 "Y/Ve4+ 'lt;g7 2 'le7+, and with the king on c8 - 1 'ii'g4+ rttb8(b7) 2 'ii'b4+. Nevertheless, Black has a way to win - but instead of 21 . . . I:.xa1 ? he should play 21 . . . b2!. Here is the analysis by Nunn and Burgess: 22 gB'fi (22 l:lxa2 .l:i.c 1 + 23 'lt;d4 b1"YIV 24 ga"fk 'ikb4+ with a quick mate or win of the white queen) 22 .. .1J.c1+! 23 Wd5 (23 J:!xc 1 bxc1"fk+ 24 'lt;b3 'ilb 1 + 25 Wc4 'fib5+) 23 . . . .l:!.c5+ 24 'it;d6 .l:!.c6+! 24 . . . bxa1"ik? is premature: 25 "fibB+ 'lt;a6 26 'laB+ 'it;b5 27 "YIVb7+ 'lt;c4 28 "ilif7+ 'it;b4 29 'lb7+ 1:.b5 30 "ike4+ 'it;b3 31 "ilie6+! with perpetual check. 25 cJ,;d7 After 25 cj;d5 bxa 1"YIV 26 "YIVb8+ 'lt;a5 27 'fa7+ 'it;b5 28 "ilib8+ I:.b6 29 'ii'e8+ 'it>b4 30 'ffB+ 'it;b3 the checks come to an end. 25 . . . bxa 1"YIV 26 "YIVb3+ No better is 26 "ikb8+ 'it;a5 27 "ik a8+ 'it>b4 28 'lb7+ 'it;a3 29 "ilia7+ 'it;b3 30 "ilib7+ 'it;c2! 31 "ilixc6+ "Y/Vc3 32 "Y/Va4+ 'it;b233 ikb5+ 'it;c 1 34 "YIVf1 + 'lt;c2. 26 . . .

Besides, Wh ite's defence can be improved at the very start of the variation . I nstead of 9 Wb3?! we can play more cunn ingly - 9 Wa3! , so that the pawn should move to a4 without check. 9 . . . a4 (no better is 9 . . .b6 1 1 Wb4 leads to a position of mutual zugzwang , and with Black to move. 1 1 . . . .l:te5 is pointless, since 1 2 . . . l:Ie3 is not a threat and White can s imply advance h is pawn. After 1 1 . . . Wa6(c6) 1 2 .l:!.g 1 .l:te5 the move 1 3 . . . l:te3 i s n o longer deadly and again 1 3 g5 can be played . Let us try 1 0 . . . Wc6!? 1 1 Wb4 Wb6. Now it is Wh ite who is in zugzwang. We a l ready know that he loses after 1 2 .l:!.g 1 .l:!.e5; let us see whether 1 2 .l:!.g2 l:Ie5 1 3 Wa3! helps h im . The d ifference compared with the position of the rook on g 1 is immediately apparent: after 1 3 . . . Wa5 14 g5 the black rook cannot invade at e2 . B lack is forced to advance h is pawn : 14 . . . b4+ . 92 � Typical Endings with Connected Passed Pawns To where should the king move? The outcome depends on this. Of course, 1 5 'it>a2! , so that the a-pawn should advance without check. All the same Black plays 15 . . . a3 (but now without gain of tempo ! ) 1 6 g6 'it>a4. Threatening 1 7 . . . b3+ with mate . White loses after 1 7 .l:.g 1 b3+ 1 8 'it>a 1 a2, but he finds the defence 17 Zig4! l:te2+ 18 'it>a1 ! . And now 18 . . . a2 is dangerous only for Black: 1 9 g7 'it>a3 20 .l:!.g3+ b3 21 .l:!.xb3+! 'it>xb3 22 g8'it'+. Thus we have establ ished that in the event of 8 . . . '1t>c5 White gains a draw. In the game I moved my king the other way. 8 . . . 'it>e5 You see , the king has nevertheless reached e5, but instead of going there immed iately it has wasted time, by wandering about on the e6- and d6-squares. 9 'it>b3 White intends by Ua 1 to force the advance of one of the pawns, and then to establ ish his k ing between them. 9 . . . 'it>f4 1 0 Ita1 Here I did not bother to ponder over which pawn to advance , and this was a mistake - one pawn move leads to a win , and the other to a draw. Let us first see what happened in the game. 1 0 . . . 1 1 'it>b4 1 2 .l:!a3?! a4+? 'it>xg4 My opponent embarks on a ru inous course. He probably thought that he would be able to restrict my king along the 3rd rank, but in fact his rook is badly placed here . 1 2 . . . 'it>f4 1 3 .Uc3?? Any move along the 3rd rank loses - the rook should have moved off it. 1 3 . . . .Ug3 My rook goes to b3, after which the pawns queen of the i r own accord . B lack won easi ly. But how should my opponent have de fended? Let us assume that we do not know the theory of endings with such a pawn arrangement - let us try acting simply by using common sense . Let us ask the question : 'What does Black want?' Undoubtedly, to take his king to b2, after which it wi l l be possib le to g ive up the b5-pawn and queen the a-pawn . Let's try and h inder the movement of the king, by cutting it off along a fi le . 12 .l:!.f1 .l:!.f5 1 3 .l::!.e 1 'it>f4 1 4 1:te2 .l:!.e5 1 5 1:td2 �e3 1 6 ltd 1 .l:t.g5 1 7 .l:!.d8 �e4 1 8 .:td 1 1:tf5. It is important not to place the rook on e5 - then a check on e 1 wi l l d rive the king away. 1 8 . . . l:td5 is premature in view of 1 9 Ite1 + . Black must play for zugzwang. The white king on b4 is ideal ly placed , so the position of rook must be improved . 1 9 �d2 Itd5 20 .Uc2 (now 20 11e2+ 'it>d3 is hopeless for White) 20 . . . 'it>d3 2 1 .l:tc8 (21 l1h2 is also not bad ) 2 1 . . . 'it>d2 22 l:tc7 'it>d 1 . (see next diagram) Up to this point White has not been in any particu lar danger, and he could have de fended in various ways . But here he must make an accurate move (23 .:tc3 or 23 l:f.h8), s ince Black has created the concrete threat Typical Endings with Connected Passed Pawns ttJ 93 23 . . . l:.d2 . For example, 23 'R.c7? l:td2 24 l:.c3 (24 �xb5 a3 25 �b4 a2 26 l:ta7 �c1 ) 24 . . . .U.b2+ 25 �a3 .l:.b1 . After 26 l:th3 there follows 26 . . . �c2 with the threat of 27 . . . .l:.b3+, while if 26 l:tc8 , then 26 . . . �d2 , and the king approaches the pawns. I t has acqu i red an excellent shelter from the s ide checks at a5 . This is one of the important winn ing posi tions. And now - the main d rawn position , which it is also essential to know. H. Kasparian Could we have reached this position? Quite possibly. Wh ite could a lways have placed his rook on the 3rd rank. The only plan to play for a win is 1 . . . �c2 2 l:th2+ l:td2 3 l:th3! ( it is important to control the a3-square) 3 . . . �b2 . At fi rst sight White is in trouble Black intends 4 . . . .l:1d4+ and 5 . . . a3 . But let us verify: 4 .l:.g3 l:td4+ 5 �c5! (5 �xb5? a3 6 .l:.g2+ �c3 7 .l:.g3+ .l:ld3) . If the rook goes to e4 , it is now possible to capture the b5-pawn and after 6 . . . a3 to begin side checks. The king has to step onto the d-fi le , but then the rook attacks the a-pawn and this leads to a draw. This was Kasparian 's conclusion. I n this position I d iscovered another curious subtlety: B lack can try 5 . . . :1d 1 ! . Again it is not possible to capture on b5, and 6 �b4 is necessary, but then there fol lows 6 . . . l:.b1 . Now it is essentia l to take the pawn: 7 �xb5! a3 8 �a4 a2 9 l:tg2+ , and the king is deprived of the important b 1 -square - draw! [There is another way to draw: 6 .l:tg2+ �b 1 7 1:tg3 or 6 . . . �c3 7 �xb5 a3 8 �a4 - Dvoretsky.) Let us return to the position after White's 1 Oth move. We have seen that 1 O . . . a4+? leads to a d raw. Let us now analyse 1 O . . . b4! 1 1 �a4 ( 1 1 'R.g 1 .l:.x:g4 is hopeless) 1 1 . . . �xg4. This pawn configuration is obviously stronger than a4-b5, s ince after the sacrifice of the a5-pawn the remain ing b-pawn is more dangerous than the a-pawn , and affords more winn ing possib i l it ies. For the moment the black king is free to approach the queenside ( 1 2 .l:.f1 1:tf5 etc. ) . Let us see what methods of defence White has against pawns on b4 and a5. The first: playing for stalemate. (see diagram) If the black king goes to c3 , there fol lows llc2+ ! . But this mechanism is easi ly de stroyed - playing the black rook to the 2nd rank proves decisive. 94 � Typical Endings with Connected Passed Pawns The second: the attempt by White to place his own king in the way. The drawback to the position of the king on b3 is that it comes under check along the 3rd rank. 1 . . . 'it>d4 2 1:!.a2 l:te3+ 3 'it>a4 (forced) 3 . . .'�c3, or 2 l:!.a4 l:!.e3+ 3 'it>b2 'it>c4! 4 .l:.xa5 l:!.e2+, and a won position, well known in theory, is reached . Black wins in roughly the same way with the enemy rook on a8 ( instead of a 1 ) : 1 . . . 'it>d4 with the idea of . . . .Ue3+ . The third : to cut off the black k ing along What is the s implest way to win here? Let's improve the position of the rook: 1 . . . l:!.e5. The threat is 2 . . . .l:.e3+ , l ift ing the blockade of the pawns . Both 2 l:.d 1 + 'it>c5 3 'it>a4 .l:!.e3 and 2 'it>a4 'it>d3 (not immediately 2 . . J:te3? 3 'it>xa5 b3 4 'it>b4) 3 .l:tc8 (or 3 'it>b3) 3 . . . 1:!.e3 4 l:.c7 'it>d2 are hopeless for White . You see that the key square for the king in th is type of ending is d4 - it is very important to occupy it! And after this - accord ing to ci rcum· stances : if the wh ite king is at a4, the route . . . 'it>d4-c3-b2(c2) becomes possible. With the king on b3 it comes under checkand the black king can then go to c5 and b5. I t a l l seems to be very s imple, but look at the fol lowing position : the fi le. What is the evaluation? Draw! The king Typical Endings with Connected Passed Pawns ltJ 95 cannot break through anywhere. We arrive at a general ru le for this type of end ing : - If the black king is cut off in i ts own half of the board , the position is d rawn ; - But if it breaks through into the opponent's ha lf of the board , the position becomes won . A general conclusion for this type o f ending also suggests itself: Black's plan of moving his king towards the white pawn and capturing it leads to a win , whereas the plan o f playing the king to the help of the queenside pawns only d raws. However, later analysis sometimes intro duces serious corrections into seemingly establ ished conclusions. On one occasion I looked more carefu l ly at the position after 8 . . .�e5. Why did White play 9 �b3 ? The immediate 9 J:ia1 ! was far more log ica l . Now the reply . . . b5-b4 is no longer possible, and after 9 . . . a4 1 0 'lt>a3 (not 1 0 �c3 .l:!.xg4 1 1 .l:!.b 1 l:ic4+) White need not fear 1 O . . . l:!.xg4 1 1 .l:!.b1 with an immediate d raw. Black repl ies 1 0 . . .'it>d5 , but 11 'it>b4 �c6 1 2 l:Lg1 leads to an already fami l iar d rawn position . The number of mistakes that the two players made in this endgame! The reason was an inadequate knowledge of the theory of rook endings. They had no 'beacons' by which they could be gu ided . Thus in the game the moving of the king to the kingside (alas, rather belatedly) should have led to a d raw. Then I again returned to the position after 8 . . . 'it>c5 9 'lt>a3.

From the examples demon strated below, you wi l l see that i n the USSR Cup (the club team championship of the country) in 1 976 in Tbil isi our Burevestn ik team was indeed lucky. But when you have by no means the most impressive l i ne-up , competitive good fortune alone is not enough to win by an enormous marg in (before the last round we were a l ready T'h points ahead of our nearest riva ls) . Our success was largely secured by the friendly atmosphere reigning in our team , the benevolence and mutual help. An important role was a lso played by our superiority i n the analysis of adjourned positions (although from the exam ples g iven below you would probably not say this) - when they were resumed the resu lts of a good dozen games came as a pleasant surprise to us . On the even ing before the adjournment day our leader Vasi ly Smyslov adjourned h is game against Mikhai l Tal in what was a dangerous position for h im . At a team meeting he said that the fol lowing day he would need help with the analysis . 'Of course, of course, let's look at the position together, ' grandmaster Ta imanov offered his services. 'Thank you , Mark Evgenevich , but I would l i ke to work with Mark lzrai levich , ' Smyslov repl ied . Of course , it is flattering to have the reputation of being a good ana lyst, a lthough at t imes it is sl ightly onerous - after al l , my game was a lso adjourned . But the fol lowing morning Smyslov and I sat down to look at his position . After three hours of exception a l ly i ntensive work my head was l itera l ly spl itting , but on the other hand it appeared that we had found a way to save the game. Tal - Smyslov Tbi l is i 1 976 Of course, it is unfavourable to play 42 g5? .l::i.xh5 43 tt::lf6+ �g6 , and therefore Tal 's sealed move was obvious . 42 tt::lxd6 cxd6 Now the capture of the b6-pawn a l lows Black to activate h is king : 43 .l::i.xb6 �h6! 44 .l:!.xd6+ (44 f4 !? exf4 45 .l:!.xd6+ also does not win ) 44 . . . �g5 45 f3 e4 ! with counterplay sufficient for a d raw, for example: 46 .l:!.g6+ 'it>f4 47 fxe4 a4. Wh ite must play more sharply. 43 .l::i.xd6! We have a choice between 43 . . . b5 44 .l::!.a6 a4 and 43 . . . .l::i.b 1 . In both cases the opponent sends his k ing forward . The queenside 98 � Adventures on Adjournment Day pawns do not advance very qu ickly - during th is t ime danger impends over theblack king. The fol lowing variation is an instructive one, i l lustrating the typical ideas in the position and the d ifficulties facing Black. 43 . . J�tb1 44 'it>f3!

Even in such sharp endings, where every thing can depend on a single tempo, sometimes it is not worth immed iately delving into the mass of variations . You should fi rst logica l ly weigh up the situation and look for a p lan , a general idea , which should be carried out. What, do you th ink, is this idea? It turns out that Black should switch his rook to the 8th rank. Fi rstly, from here it covers the king - to checkmate it the opponent wi l l have to br ing forward his king and both pawns, and this demands time. Secondly, it may be possible to place the rook behind its own pawn and advance it, while g iving up the other. So, the general p lan has been found . It is merely necessary to firid the most accurate way of implementing it. 43 . . . b5 As Tal commented after the game, 43 . . . .Ub1 was nevertheless possible, but only in connection with the plan indicated above : after 44 'it>f3 a4 45 'it>e4 Black should play 45 . . . .l:tb4+ ! 46 'it>f5 .l:!.f4+ 4 7 'it>g5 .Uf8 . 44 �a6 45 'it>e3 a4 We considered 45 'it>f3 to be more accurate. Tal was concerned about the reply 45 . . . a3, but in th is case Black loses: 46 c.t>g2 .Ua1 47 g5 b4 48 g6+! (not 48 �a7+? Wg8 49 g6 Iic1 50 h6 l:!.c8) 48 . . . Wh6 49 .l:!.a7 with the decisive th reats of 50 l:th7+ or 50 g7 'it>h7 51 h6 and 52 l'la8 . Therefore Smyslov would have played as in the main variation of the analysis - 45 . . Jlc1 ! . But after the move in the game Black acqu i res an add itional possib i l ity. 45 . . . lle1 + 4 6 'it>f3 46 . . . �c1 46 . . . e4+ 4 7 'it>f4 �e2 was also qu ite possi ble. We analysed sharp variations such as 48 'it>g5 �xf2 49 �a7+ 'it>g8 50 h6 e3 51 'it>g6 �f8 and d id not see how Wh ite could win. But on the other hand the main plan of defence a lso seemed sufficient for a draw, so that it was not easy for Smyslov to make a choice . He real ised perfectly wel l that, i n view of the lack of t ime for ana lysis, in any branch a mistake cou ld creep in . The on ly question was, where was this more prob able? 47 c.t>e4 �c4+?! Adventures on Adjournment Day C2J 99 This was how we intended to switch the rook to the 8th rank. True, in this way the position of the wh ite king is improved , although the e5-pawn remains invul nerable. We rejected 47 . . . J:!.c8 ! , because we considered that Black was lost in the position arising after 48 'it>xe5 .l:!.b8 49 g5 b4 50 .U.a7+ 'it>g8 51 �a4 b3 52 l1a 1 b2 53 l:!.b1 . Not long before the resumption Vasi ly Vasil ievich came up to me. 'You know, ' he said , ' i t would appear that White's three pawns do not win . ' 'That can't be so ! ' I said in su rprise , and I tried to refute h is conclusion , but without success. Here is the key position . 1 . . . l:tb3+ 2 'it>d4 ( 2 'it>d2 .U.b4 3 f5 .i:i.b5) 2 . . . J:.b4+ 3 Wc3 l:txf4 4 l:txb2 .U.h4! with a draw. The discovery made by Smyslov is instruc tive and pretty, and I th ink that it is of considerable importance for the theory of rook endings. But we no longer had t ime to verify it thoroughly. {Many years later grandmaster Carsten Muller nevertheless found a winning plan for White. He suggested 2 '>t>e4 l:!.b4+ 3 �f5 l:!.b5+ 4 '>t>e6 (4 �g4 l:i.b4 is hopeless) 4 . . . 1:!b6+ 5 �d5 l:!.b5+ 6 �c6 l:!.b4 7 f5 tlg4 8 h6+ rtlh7 9 l:!.xb2 l:i.xg5 10 l:!.f2 etc. If Black waits: 7 . . . .U.b8 8 h6+ �h 7, the most accurate is 9 Wd5!

Without waiting for advice , he sa id that he would th ink about i t once more at the board . And he made h i s choice in favour of the main variation , which we had planned from the very start. Alas, it was here that a mistake had crept i n . 48 'it>f5 49 'lt>g5 50 h6! .l:!f4+ l:i.f8 Here it a l l became clear to Smyslov. I n our analysis we had somewhere g iven a check on a?, after which there is no win . In sharp endings such as this , every tempo is precious - White leaves the king on h7, in order to advance h is pawn to g6 with check. 50 . . . b4 51 l:txa4?

After this White is left with a single target - the e4- pawn . The impression was that Black could fa i rly easi ly solve the problem of its defence.

As you see , not real ly so much and not rea l ly so d ifficult! Let us see how another, rather more ex tensive section in our system of endgame knowledge is constructed - the theory of endings, in which a rook fights against pawns. A basis for study can be provided by any endgame manual , for example, l lya Maizel is's monograph Ladya protiv peshek (Rook against pawns) , publ ished in 1 956 ( in contrast to opening books, those on the endgame hardly date at a l l ) . Here some 400 How to Study the Endgame ltJ 1 1 positions are examined . Clearly we are not able to study and remember all this informa tion . We need to select the most important key endings for practical purposes. But how to choose the most important material? This is the main problem . What tel ls here is the player's i ntel lect , and h is abil ity to work with books , to general ise, and to draw conclusions. He is a lso helped by the knowledge (even if incomplete) that he already has, and by h is own practica l experience in the g iven field . The play i n endings with rook against pawns is dynamic in character, and every tempo has a decisive influence on the outcome. It fol lows that here there is no large-scale strategy, battle of plans, or deep regu larities (as , say, in endings with opposite-colour b ishops). There are also hardly any exact positions, by relying on which we could avoid the need for concrete calculation . The main role is played by a knowledge of typical techniques, which help the correct move to be found more qu ickly and variations to be calculated more certa in ly. The procedures are best mastered with the help of elementary positions, in which they are employed and where their action is not obscured by extraneous analytical deta i ls . Subsequently the exact pattern of the position my be forgotten , but the impression of the techn ique wi l l remain . Sometimes such a posit ion - the conveyor of the technique - is s imu ltaneously an exact position which is important for us ; in this case, of course, we should memorise it . So, using some very simple schemes, let us examine the main ideas which apply in endings with rook against pawns. Cutting off of the king White wins, by playing 1 .l:tg5! . When the pawn reaches a3 , it can be e l iminated by llg3 (or with the pawn on a2 - by l:.g 1 and l:r.a 1 ) . If it is B lack to move , then 1 . . .'it>b5(c5) ! leads to a draw - as it is easy to see, cutting off the king along the 4th rank by 2 l:tg4 does not ach ieve anyth ing . Promotion of the pawn to a knight 1 l:.h2+ 'it>c1 2 'it>c3 b1lD+! 3 'it>d3 lb a3 4 l::ta2 lbb1 1 with a draw, but not 4 . . . lbb5? ( in end ings with kn ight against rook, the knight should not be separated from the k ing) . A draw also results from 1 . . . 'it>b1 2 'it>b3 'it>a 1 ! 3 l:txb2 - sta lemate. But with a 12 � How to Study the Endgame bishop's pawn or a central pawn only the promotion to a knight saves Black. However, with a rook's pawn this idea no longer helps. 1 'it>b4(c4) a2 2 'it>b3 a 1 4J+ 3 'it>c3, and Black is in zugzwang. I t is usefu l to note that if B lack also had a pawn on b5, a l l the same this would not save h im: 3 . . . b4+ 4 'it>xb4 4Jc2+ 5 'it>c3 tt:Je3 6 'it>d3 4Jd5 7 .Uh4 'it>b2 8 .Ud4, and the knight, which is separated from the king , is soon lost. 6 l:.h4! ( instead of 6 �d3) wins even more quickly: 6 . . . �a2 (6 . . . 4Jd 1 + 7 'it>d2 4Jb2 8 .l:i.b4 'it>a2 9 �c2 'it>a 1 1 0 l:.b8 ; 6 . . . 4Jd5+ 7 �b3 'it>c 1 8 .l:!.c4+ �b 1 9 .Ud4) 7 .l:.a4+ �b 1 8 .Ue4 4Jf5 9 .Ue5 4Jd6 1 0 b3 c1 1 1 .i.:i.c5+ 'it>b 1 1 2 .Ud5. Stalemate We have already examined one very impor tant practical instance of stalemate . Here is another example (wh ich , incidental ly, consti tutes one of the few 'exact' positions that it is usefu l to memorise) . I t is hopeless to play 1 . . . a2? 2 .l:.b8+ 'it>a3 3 'it>c2! a 1 4J+ 4 'itc3 'it>a2 5 .Ub7 with zugzwang. The only way to save the game is 1 . . .

As you see, when learn ing new ideas one can sometimes repeat material that has been covered earl ier ( in this case - promo tion of the pawn to a knight) . An intermediate check to gain a tempo The diagram position arose in the game Korchnoi-Kengis (Bern 1 996) . B lack re signed , after calculating the fol lowing forced variation .

By not al lowing the enemy king to approach the pawn , Black ga ins a draw. It is i ncorrect to play 1 . . .'1t>b 1 ? 2 'lt>b3 a 1 lD+ 3 'lt>c3. Now let us examine a sl ightly more compl i cated example. 1 . . . a5? does not work i n view of 2 .l:!.h5! - we a l ready know this idea. But 1 . . . 'it>b5? is also bad : 2 W a5 3 'lt>e6 'it>c4 (3 . . . a4 4 'it>d5) 4 .l:ta8 ! 'lt>b4 5 'it>d5 a4 6 'it>d4 'lt>b3 7 'it>d3 a3 8 .l:tb8+. The only saving move is 1 . . . '1t>c5! , preventing the approach of the enemy king to the pawn. Outflanking The ideas of 'shoulder-charge' and 'out flanking' are vividly expressed in a famous study by Richard Reti ( 1 928) . 1 l:td2(d3) 1 ! d4 2 .l:i.d1 ! 'it>d5 3 'it>d7! , and Black is i n zugzwang: if 3 . . . '1t>c4 4 'lt>e6, or 3 . . . '1t>e4 4 'lt>c6. 1 .l:td 1 ? is a mistake : 1 . . . d4 2 'it>d7 (2 'lt>f7 'lt>e4 3 'it>e6 d3) 2 . . . '1t>d5! (Black prevents the outflank ing) 3 �c7 'it>c5! (3 . . . '1t>c4? 4 'it>d6! d3 5 'it>e5) , and it is Wh ite who ends up in zugzwang . Let us now turn to positions in which a rook fights against two connected passed pawns. Mate threats to the opponent's king I f the pawns are far advanced (two black pawns on the 3rd rank , or one on the 2nd rank and the other on the 4th ) , then the rook is unable to stop them. However, sometimes 14 � How to Study the Endgame it is possible to save the game, by pursu ing the opponent's king when it is p inned to the edge of the board . B. Horwitz, J.

I should mention , i ncidental ly, that d ifferent players can single out d ifferent ideas and ru les, depending on their experience and knowledge. I n the above example attention should be paid to the manoeuvre with which the black king escapes from the checks (after 1 l:.xb3?) . But you can a lso d isregard it , if this idea is a l ready wel l known to you . The best position for the rook i s beh ind the more advanced pawn 1 .S.g6!

Thus the system of defence with the bishop on b7-a8 runs in to a far from obvious refutation . Black could have stuck to another l ine of defence with h is bishop on g2-h 1 .

I hope that they will also appeal to you . Their beauty l ies in the unusual amount of work carried out by the wh ite knight, the paradoxical manoeu vres of the wh ite pieces, and above al l the precision and depth of logic behind these manoeuvres. Before enjoying the solutions , try to find the answers yourself. I should warn you before hand: the problems are very d ifficult , and you wi l l most probably have to move the pieces on the board (perhaps only the second example might be solved in you r head ) . But even so, don't b e in a hurry to make moves - first reason to yourself about the final and intermed iate aims of both sides, the plans they wi l l carry out, any important intermediate positions, and so on . N. Grigoriev 1 932 A knight can stop a rook's pawn, if it succeeds in 'touching' any square in its path (apart from the corner square h1). In the g iven instance it is clear that the knight wi l l aim for the h2-square . How to reach it seeing as the black k ing stands in its way? Here are some logical considerations, which wi l l make it easier to find the solution . The knight can reach h2 via g4 or f1 . Each of these routes can be control led separately by the black king . I t is necessary to create a 'double attack' - by threaten ing to go to h2 by both ways . The kn ight can reach f1 via d2, and g4 via e5. Do you see the intersection point of these two routes? 1 tt'lb4! h5 2 tt'lc6! Not 2 tt'ld5+? 'itof3 ! , and the pawn cannot be stopped .

It turns out that B lack can save a very important tempo by avoid ing the attack on the knight and satisfying h imself with merely restrict ing its mobi l ity : 1 . . .b4 'itf5 3 'it>xb5 h5 , and the pawn queens. This means that i n reply to 1 . . . 'it>e6 White must immedi ately tackle the h-pawn with his knight.

'it>d2? 2 lt:Jf4 (2 tt'le5 �d 1 3 lt:Jf3 is a lso good ) 2 . . . 'it>d 1 3 Wg2 . He must play 1 . . . 'it>d 1 ! 2 lt:Jf4 (2 lt:Je5 lt>d2 3 lt:Jf3+ �c3) 2 . . . 'it>d2 ! , and if 3 'it>g2 , then 3 . . . d 3 ! with a draw. From this the fol lowing conclusions can be drawn : if Wh ite plays We 1 , then with the knight on d3 Black must reply . . . 'it>c2 ! , whi le with the knight on f4 , e5 or c5 the correct rep ly is . . . 'it>c3 ! . The position with the knight on c5 , b lack k ing on c3 and wh ite k ing on e 1 is one of mutual zugzwang . The fol lowing step i n our logical analysis of the position is to clarify the importance of the e4-square for the kn ight . Let us suppose that the kn ight stands on e4 , the wh ite k ing on d 1 , and the black king on b3. Then if it is Wh ite to move 1 �c1 ! is decisive. But things are no easier for Black if it is h im to move : if 1...Wb2 there fol lows 2 tt:Jc5 ! 'it>c3 (2 . . . �b1 3 tt'le6) 3 �e1 ! , and the afore-mentioned position of mutual zugzwang is reached with Black to move . Thus the knight must be brought to the e4- square. This is not at a l l easy to ach ieve , seeing as White constantly has to watch out for . . . d4-d3 . 1lLle1 �b2 2lt:Jd3+ �c3 Noth ing is changed by 2 . . . �b1 3 tt:Jc1 �b2 4 tt'la2 , whi le 2 . . . �b3 shortens the solution : 3 tt'lf4 Wb2 (3 . . .

As you remember, 4 . . . �b3? 5 �c1 ! �xa2 6 'it>c2 is bad for Black. He is forced to move his k ing along the 1 st rank , away from the c3- and c4-squares. 4... �b1 5 lt:Jb4 'it>b2 6lt:Jd5 'it>b3 6 . . . 'it>b1 ? loses immediately to 7 lt:Jc7 �b2 8 lt:Jb5. 7lt:Jc7!

One of the most common and serious is poor techn ique in the conversion of an advantage. Even champions some times suffer from th is i l l ness - it is sufficient to remember the 1990 match for the world championship between Garry Kasparov and Anatoly Karpov. How frequently after an unsuccessfu l game do we state with vexation to our opponent, trainer, ora casual spectator: ' I had a completely won position ! ' But it is pointless complain ing about fate - it is better to th ink about the causes of the mistakes made, and endeavour to understand what playing or personal deficiencies are behind your er rors . I wi l l now dwel l briefly on the main factors which h inder the normal conversion of an existing advantage. I . Tiredness to wards the end of a game It is clear that after several hours of intensive struggle a player becomes tired . But some become more t ired than others . I t is in the last few minutes that the fate of a game is often decided , and therefore many additional points can be gained by a p layer who reta ins a sufficient reserve of energy towards the end of a round . The play of grandmaster Yusupov is a lways time and energy on solving the problems wh ich confront h im in the fi rst half of a game. But for its later part he often lacks strength, and here he makes serious errors . It was only for th is reason , for example , that he did not win h is Candidates semi-fina l match in 1989 against Karpov. Yusupov constantly outplayed h is formidable opponent, but was u nable to convert th is into wins on account of t iredness towards the end of a game. Here is one of the most annoying examples. Karpov- Yusupov Candidates Match , 6th Game, London 1989 deep and interesting , and he spends much Yusupov saw that in the variation 38 . . . a3? Converting an Advantage ttJ 1 1 3 39 .l:la6 .Uf2+ 40 'it>e1 a2 41 f5 he would not have time to win the rook: 4 1 . . . .Uxh2 42 f6 l:ih 1 +? 43 'it>e2 a 1 'i!V 44 .l::!.xa 1 .l::!.xa 1 45 f7. Therefore he played 41 ... 'it>d7 , and after 42 f6 'it>e6 43 .l:ta8 ! 'i.t>xd6 44 f7 .l::!.xf7 45 .U.xa2 lt>e5 46 lla6 the players agreed a d raw. Yet Black could s imply have captured the pawn: 38 . . . l:txh2! 39 .l:.a6 39 f5 .Uf2+ and 40 . . . .l:txf5 . 39 . . . l:.f2+ 40 'it>e1 .l:txf4 41 'i.t>e2 .U.e4 With an easy win , for example : 42 .l:ta5 (otherwise . . . h6-h5-h4) 42 . . . '1t>d7 43 l:.d5 h5! 44 IIxh5 'it>xd6. Why d idn 't Artur play this? By h is own admission , at that moment his mind had simply switched off, and he d id not see any other possib i l it ies apart from 38 . . . a3?. I f you are let down by ti redness, perhaps i t means that a l l is not wel l with your physical preparation? The prescription in such cases is clear - you must do more physica l exercise and devote more t ime to sport , i n particu lar exercises for stamina (for exam ple, slow but long-distance runn ing) . Con sider devising a rational dai ly reg ime during a competition , enabl ing you to relax properly and regain your energy before a new game. F inal ly, a lso during a game you can husband your strength , by using for relaxation those brief minutes of respite when it is your opponent's turn to move . However, a l l these are fa i rly serious questions , demanding a special d iscussion , and not just a brief mention . II. Insufficiently stable nervous system Throughout a game it is very important to mainta in fu l l concentration and u nbroken attention to everything that is happening on the board . But it is not everyone's nervous system that is ready for such prolonged tension . Often a player composes h imself only at especia l ly important moments of the strugg le , but when the main problems seem to h im to be resolved , he loses his vig i lance and beg ins act ing carelessly. It is here that mistakes usual ly occur. Mestel - L. Popov Olympiad , Malta 1 980 White is a sound pawn to the good , but he now has to resolve a d ifficult problem: what posit ion to go in for, so that the opponent wi l l have the least in the way of counter chances. The fol lowing possib i l ities suggest themselves: a ) 25 .l:te 1 .l:I.d2 (25 . . .'it'c5 is less accurate in view of 26 'iWa6! .Ud2 27 .l:.e2) ; b ) 25 'i�Nxc6 .l:.xd 1 + 26 .i.xd 1 'iVxa2 (stronger than 26 . . . 'i�Nxe5 27 'ifa6! ) 27 'ifb5 'iVa 1 28 �e2 a5 , and it is not easy for Wh ite to strengthen h is position ; c ) 25 .Uxd8+ 'i!Vxd8 26 'ii'xc6 'i�Nd2 ; d ) 25 .l:I.xd8+ 'i!Vxd8 2 6 �xa7 'iVd2 . I n every case Black reta ins cou nterplay, and the outcome remains unclear. Jonathan Mestel found an excel lent solu t ion . 25 .l:.xd8+! 'i�Nxd8 1 1 4 � Converting an Advantage 26 i.c4! ! The bishop wi l l securely defend the king from f1 . For the moment the queen remains on b?, from where it defends the b2-pawn. The a?- and c6-pawns are weak, and soon White is sure to create a passed pawn on the queenside. 26 . . . �d2 27 i.f1 'lt>g7 27 .. .'ti'c2 was more tenacious, preventing the fol lowing strong move by the opponent. 28 a4! aS 29 'ir'b6 h5 Black's last fa int hope is to break up the wh ite king's defences by the advance of h is g- and h-pawns. He no longer has any other possibi l it ies. 30 'ii'xa5 i¥xb2 31 'ir'b4 li'a1 32 a5 g5 33 a6 g4 It is clear that Black's position is completely hopeless. But it is very dangerous, in bel ieving th is , to weaken your attention and stop checking variations. For example, if Wh ite plays 34 'ii'b8 'ii'c1 35 a?? (35 'ii'b6! is correct) , then after 35 . . .'!"i'le3! 36 fxe3 'ii'xe3+ 37 'it>h 1 "it'c1 (e1 ) 38 'it'h8+ (38 'ii'b6 �xf1 + 39 �g 1 li'a6 with equal ity) 38 . . . 'it>xh8 39 a8'6'+ 'it>g? 40 'ii'a6 "ii'xc3 Black ga ins qu ite good saving chances - at any event, a lengthy struggle sti l l l ies ahead. 34 'ii'b?! was strong , ensuring the advance of the pawn whi le reta in ing the option, in case of necessity, of defending the bishop from a6. 34 g3 ! also came i nto considera tion , after which Black does not have a s ingle sensible move . 34 'it'b6 h4 35 a7?! Was it worth a l lowing the open ing up of White's own king position? 35 g3 ! would have g iven an elementary win . 35 . . . g3 ! 36 ii'a6? Here it is - relaxation when only one step away from victory! 36 fxg3 hxg3 37 h3 would have won , for example , 37 .. .'i!Va2 38 'lt>h1 tt'lh4 39 ii'a6 'ii'f2 40 a8'ii' tt'lf3 41 'i!V8a7 c5 42 'i!Vxf?+ ! 'i£txf7 43 'ii'b?+ and 44 'i!Vxf3. However, such a variation is too compl i cated for a player in time-trouble . In any case , with more accurate preceding play the game could have been concluded far more s imply. 36 . . . gxf2+ 37 'i£txf2 I n the event of 37 Wh 1 'ii'c1 38 a8'it'? White, paradoxical ly, even loses - after 38 . . . tt'lg3+! 39 hxg3 hxg3 there is no defence against mate by the queen on h6 . 37 . . . i¥xc3 Aga in mate is threatened . 38 i.d3 Draw. 39 i.e2 40 We1 41 Wf2 'i!Vd2+ 'iid4+ i¥c3+ How can the nervous system be tra ined to endure prolonged tension? Here too it is probably not possible to get by without Converting an Advantage ttJ 1 1 5 physical preparation ( 'healthy in body, healthy in mind ! ' ) ; self-tra in ing exercises or even yoga are probably usefu l . Specific chess training is a lso possib le . You can practice playing specia l ly selected exercises, i n wh ich you have to find a long series of the only correct moves. Try conducting ind i vidual games or even entire tournaments with the aim of concentrating to the maxi mum throughout the entire game. Ill. Time-trouble Nearly every player can remember depress ing instances of t ime-trouble adventures, in which the fru its of all the preced ing work were ru ined. But even so I wi l l show you one more example, together with an instructive assessment of his own actions , which was given in his notes by an ex-world champion . Alekh ine - Tylor Nottingham 1 936 Black's posit ion is, of course, completely hopeless. If 46 . . . '>i'xd5 there fol lows 47 ::l.d1 + '>i'e6 (47 . . . '.i?e5 48 i..c6) 48 '>i'c3 . Tylor tries h is last time-trouble chance.46 . . . tbxa4 47 '>i'd3?? Regarding this Aiekhine writes in the tou rna ment book: An awful move, the fact that White was very short of time is, to my mind, as little to be considered as an excuse, as for instance the statement of the law-breaker that he was drunk at the moment that he committed the crime. The inability of an experienced master to deal with the clock should be considered as grave a fault as a miscalcula tion. White would have won by 47 i..xa4 .U.Xb 1 48 '.i?xb 1 '>i'xd5 , and now, if there is noth ing better, 49 �e8!? We5 50 h5 Wf4 (50 . . . gxh5 5 1 �xh5) 5 1 hxg6 hxg6 52 i..d7 (Aiekhine) . 47 . . . 'it>xd5 48 i..c4+ '>i'd6 49 l:!.xb7 tbc5+ 50 We3 tbxb7 Soon the players agreed a d raw. Aga in I wi l l not speak in deta i l about how to combat t ime-trouble . I wi l l merely mention two main methods: 1) 'anti-time-trouble' games; 2) time-study of games, with a subsequent analysis of the reasons for getting into time-trouble. Points are lost not on ly in your own time trouble , but also in the opponent's. This happens because a player often d isregards a wel l-known principle of how to act in such s ituations . If you have the better position, never play on the opponent's time trouble. Act exactly as you normally would, not even remembering about your opponent's lack of time. Why? By playing qu ickly, so as not to a l low the opponent to th ink over his moves, you essential ly d rive yourself i nto the same time trouble as h im . But in a d ifficult situation the opponent is fu l ly composed and mobi l ised , whereas you , by contrast, l u l led by your advantage i n t ime and position , are awa iting the fa l l of his flag and are unable to play at fu l l i ntensity. 116 � Converting an Advantage I n the hope of exploiti ng this psycholog ical effect, in d ifficult situations some players del iberately get themselves into time-trou ble, and there they often change the unfavourable course of the play. Mark Tseitlin - Makarychev Krasnoyarsk 1 98 1 Only 1 4 moves have been made, but Black's position is d ifficult , and in addit ion he had already spent nearly a l l the t ime on his clock - he had just 6 ( ! ) m inutes left for 26 moves. Obviously it is important for Wh ite to develop h is rook at c1 as soon as possib le , in order to create pressure on the c-fi le . However, after the immediate 1 5 l:tac1 he has to reckon with 15 . . . h6 . 15 h3 !? looks strong , and after the retreat of the knight - 1 6 l:tac1 . Black would probably have repl ied 1 5 . . . h6, i ntending to create compl ications after 1 6 ..tf4 cxd4 ! . But Wh ite can very wel l waste a tempo: 1 6 ..ltc1 ( 1 6 hxg4 hxg5 1 7 l:lac1 i s also not bad ) 1 6 . . . tt::lf6 1 7 ..lte3 cxd4 1 8 tt::lxd4 fol lowed by .l:!.ac1 . An unhurried method of playing, when you simply strengthen your position without allowing any counter-chances, is the most unpleasant for an opponent who is in time-trouble. 1 5 dxc5 tt::lxc5 1 6 h3 Before placing his rook on c1 , Tseitl in wants to drive away the knight . I n the event of the immed iate 1 6 l:.ac1 he was concerned about the reply 1 6 . . .'ilt'f5 , when Black ac qu i res tactica l ideas associated with the weakness of the f2-point. The fol lowing combinative variation is i nteresting : 1 7 e4! tt::lxe4 1 8 tt::lxe4 'ifxe4 1 9 tt::ld4 (the bishop at c4 is u nder attack) 1 9 . . .'iVe5 20 ..tf4 'ifh5 21 h 3 tt::lf6 (21 . . . tt::lxf2 is worse: 22 �xf2 e5 23 g4! 'iih4+ 24 ..tg3 �f6+ 25 �g 1 ) 22 g4! tt::lxg4 23 hxg4 'ifxg4 24 'it'g3 'ii'xg3 25 .bg3 ..txa2 (25 . . . ..ta6 26 b4 .l:.ad8 27 tt::lb3) 26 ..txb7 .l:1ad8 27 tt::lc6 . The concluding posi t ion is undoubted ly in Wh ite's favour, but the outcome is sti l l not clear - too many pawns h ave been exchanged . 1 6 . . . tt::lxf2 !? Th is p iece sacrifice is B lack's best practical chance . If 1 6 . . . i.xc3 the s imple 1 7 hxg4 ..tg7 1 8 l:tac1 would h ave fol lowed . 1 7 �xf2 i.xc3 1 8 bxc3 tt::le4+ 1 9 �g1 ? Th is is what Sergey Makarychev had to say: Such a disdainful attitude to one's own material can be explained only by the opponent's time-trouble. In the event of 19 Converting an Advantage lZJ 1 1 7 d6 35 lixc8 ti:'Jxf6 36 Uxc5 �xc5 37 g4 with a serious advantage. B lack's play can be improved on the 28th move , by placing his rook not on c5, but more actively on e3. And instead of 26 . . . g5 it probably makes sense for him to choose 26 . . . L'De2!? . 24 . . . 25 Jl..e3 26 il..xd4 27 Ua1 White resigned. Uad8! Uxd4 'ifc2 l:l.xe5! I t is curious that on a l l the moves that we have seen , Makarychev spent just three minutes - one half of h is reserve of t ime. 1 1 8 Converting an Advantage IV. Inadequate knowledge of endgame theory In the majority of cases the conversion of an advantage has to be carried out i n the endgame. It is clear that, if you are not fami l iar with theory, you are much more l ikely to make a mistake. Wolff - Browne USA Championsh ip , Durango 1992 It is qu ite possible (although not i nevitable) that Black wi l l lose h is e-pawn , and therefore it is usefu l to have some i nformation about endings with two pawns against two on the same wing. The most important conclusion is this: by placing h is pawns on h5 and g6, Black sets up an impregnable fortress - the opponent's k ing is unable to approach h is pawns. (see diagram) It obviously makes sense for Wh ite to prevent the erection of th is defensive sys tem, by playing g3-g4! But ifit is B lack to move, he should play . . . h7-h5 ! . But, a las , neither player knew this position . 50 'it>g2?! �d4?! 51 �f3?! g6? A strange move, wh ich sign ificantly worsens Black's position . H is king is now forced to retreat to the edge of the board (and yet he cou ld have kept it at f6) , and the h-pawn for ever remains backward . 52 'it>e4 �f6 53 l:ta7+ 54 g4! At last! 54 . . . 'it>g8 �c3 Why g ive up the e6-pawn without a fight? 54 . . . h6 55 .l:tb7 �f8 suggests itself. 55 l:!.e7 i..f6 56 l:lxe6 'it>f7 57 Ua6 57 . . . �c3? Black should have placed his bishop on h4 Converting an Advantage lZJ 1 1 9 and played . . . h7-h6 . If Wh ite's pawn were at h3 , there would be a ltogether noth ing that he could do ( I once found this fortress i n the course of a joint analysis with Boris Gu lko of one of h is adjourned positions) . With the pawn on h2 it is possible to march the king to h3 fol lowed by 'it>g3 and h2-h4 . However, this plan is not easy to carry out, and a lso in reply to h2-h4 White has to reckon with the strong reply . . . h6-h5! 58 .l:i.a7+ 'it>g8 59 l:Id7? If during the game Patrick Wolff had known about the system of defence with the bishop on h4 , he would u ndoubted ly have played 59 h4! fol lowed by 60 h5 . 59 . . . .if6 60 'it>f4 .ib2? 60 . . . h6! . 61 �c7?! 61 h4! . 6 1 . . . 62 g5 .if6 .id4 63 h4 .ib2 64 �g4 .ie5?! 64 . . . .i.a3 ! 65 h5 gxh5+ 66 �xh5 .ib4 was more tenacious. For many years this posi t ion was considered drawn , but in 1 993 the chess composer Noam Elkies nevertheless found a winn ing p lan . 65 l:tc6! .ii.b2 66 l:!.a6 .ii.c3 67 .t!.a4! 68 h5! .ie5 .ic3 No better is 68 . . . gxh5+ 69 �xh5 i.d6 (the threat was 70 .Ua8+ 'it>g7 71 l:!.a7+ 'it>g8 72 �h6) 70 .Ua8+ �g7 (70 . . . i.f8 71 g6) 7 1 .!:!.a?+ Wg8 7 2 g 6 hxg6+ 7 3 'it>xg6. (see diagram) Another important theoretica l position ! B lack loses, if his king will be shut in the corner (with a l ight-square bishop, by contrast, it would be a draw). As is not d ifficult to see, fleeing from the dangerous corner does not work in view of the u nfortunate position of the bishop: 73 . . . �f8 74 �f6 'it>g8 (74 . . . �e8 75 'it>e6) 75 l:!.g7+ �h8 (75 . . . �f8 76 l:!.d7) 76 Wg6 and wins . 69 h6 � 70 .Uc4 i.e5 71 �3 i.d6 72 .l::!.c8 'it>e6 73 .t!.h8! �5 74 l:!.xh7 �xg5 75 lid7 Black resigned . I n the second issue of the American Chess Journal grandmaster Wolff gave an excel lent commentary on this endgame. By studying his analyses, you , for example, wi l l learn how White wins if he remains with a pawn on h5 or g5 against a black pawn on h7 . Al l th is is very i nterest ing and usefu l , but nevertheless not essentia l . Whereas the fortress with black pawns on g6 and h5 should defin itely enter you r store of end game knowledge. Why in particu lar th is position? F i rstly, here it is sufficient to learn the assessment of the 1 20 � Converting an Advantage position and the basic idea of the defence (not to al low the king to approach the pawns) - you don't have to remember any compl icated variations. Second ly, th is as sessment (draw! ) is automatica l ly trans ferred to positions with a wh ite h- or g-pawn against a pawn on g6 (after a l l , Wh ite can play g3-g4 and capture on g4 with the pawn or a piece) . And above a l l , th is position is the most un iversal and informative . Very often the pawns of both sides have not advanced further than the 2nd or 3rd rank , and then it is clear that Black should aim to play . . . h7(h6)-h5 ! , and White - g2(g3)-g4 ! . One of the methods of converting an advantage is to transpose into an endgame position that is known to be theoretica l ly won . Larsen - Torre I nterzonal Tournament, Len ingrad 1 973 The simplest way to win is to sacrifice the c5-pawn. After 78 'i.t>g5! .Uxc5 79 'it>g6 fol lowed by 80 l:!.h8+ we reach an elemen tary theoretica l ending, which is completely hopeless for Black, s ince h is king is on the ' long' side of the pawn . 78 .U.c7?! Bent Larsen decided to keep both of h is extra pawns, which , of course , is a lso good enough to w in . Why then should h is decision be criticised? Wel l , because after 78 'it>g5! the game would have concluded - theory, wel l known to Larsen , would have begun. Here it would no longer be possib le to go wrong. But after the move chosen by h im , p lay contin ues in an u nfami l iar position , which means that the probabi l ity of a mistake remains . 78 . . . 79 .l:!.c6 80 .l:!.d6+ 81 f6+? �d8 c.t>d7 'it>e7 And here is the decisive mistake , which leads to a draw.

V. Poor technique in the conversion of an advantage We wi l l consider this problem in more detai l . Grandmaster Igor Zaitsev once suggested a deep and val id idea : Technique is the art of the past' . If th is is so, then a rel iable way of improving your technique is to study classic models , and , above a l l , examples from the games of p layers who were famed for their mastery in this field . P layers , such as Akiba Rubinste in , Jose Raul Capablanca , Alexan der Alekh ine , Tig ran Petrosian , U lf Anders son . . . When playing through their games, th ink about why they were able so easi ly and Converting an Advantage t2J 1 2 1 natural ly to exploit even a seemingly imper ceptible advantage, and you wi l l g radual ly beg in to notice their approach to such situat ions, those principles of converting an advantage which they consciously or sub consciously fol lowed , and the techniques wh ich they employed . We wi l l now examine the most genera l of these principles and methods . Maximum restriction of the opponent's counterchances It is very important for every player to possess 'prophylactic thinking' - the ability to constantly ask yourself: 'What does my opponent want, and what would he do now if it were his move?' But the role of prophylactic th inking increases par ticularly when convert ing an advantage, when the maximum restrict ion of the oppo nent's possib i l it ies, the e l im ination of the sl ightest counterplay or any usefu l opera tions to improve h is own position , becomes probably the main princip le . I wil l show two examples from my own games . Dvoretsky - Butnoris Kiev 1 976 nent has a bad dark-square bishop, and as a consequence - weaknesses on the l ight squares. How can I strengthen my position? The p lan of playing the knight from d2 to d5 suggests itself: f2-f3 , i.e3-f2 and tt:'ld2-f1 - e3. It would seem that it can be begun with either 22 f3 , or 22 tt:'lf1 . I t a lso makes sense to play 22 g3 , depriving the enemy knight of the f4-square . Wh ich of these three continu- ations is the most accurate? White must carefu l ly look to see what active resources the opponent has, and how he is intending to play. The move 22 . . . tt:'lf4 should not concern us too much - after 23 g3 tt:'le6 the knight does not create any threats from e6 and does not control the weak d5-square, for which Wh ite is a im ing . The attempt to create cou nterplay on the kingside with 22 . . . 'ife6 ! fol lowed by 23 . . .f5 looks more serious . For example, 22 g3 'ii'e6 23 'it'b3 f5 ! , and there is no time for 24 'ilt'xb7? in v iew of 24 . . .f4 . Or 22 tt:'lf1 'it'e6 (with ga in of tempo! ) and 23 . . . f5 . I n the second variation White has an interes t ing tactical resou rce : 23 'il:Vb3 f5 24 exf5 gxf5 25 i.xh6! jLxh6 26 .l:!.d6 �f7 27 .l:!.xh6, although after 27 . . . tt:Jdf6 h is rook is stuck in enemy territory, and 28 tt:'lfe3! f4 29 tt:'lf5 'ike6 30 tt:'lh4 e4 leads to a rather tense situation . And in genera l , when you have such a sol id positional advantage, why calculate such compl icated variations? After 22 f3 'YWe6 23 �b3 the capture on b7 is now seriously threatened , and Black is forced to d ivert either his rook, or his queen, to the defence of the pawn . I t is th is move order, therefore , that enables White to be fu l ly prepared for the opponent's counterplay. 22 f3 ! tt:'lf4 23 g3 tt:Je6 24 tt:'lf1 f6?! 25 'i!tg2! Another accurate move . 25 i.f2? is prema- Of course, Wh ite stands better. The oppo- ture in view of 25 . . . tt:Jg5 fol lowed by . . .

Usual ly, when we look at a game, we do not pay any attention to modest moves such as 22 f3 ! and 25 'it>g2! . And yet it is thanks to them that events have developed in the desirable, qu iet way for Wh ite , and the opponent has not gained the sl ightest opportun ity to activate h is game or compl i cate the play. But few are happy to defend passively without any counterchances, and in such cases new mistakes or inaccuracies are l ikely, making it easier for the stronger side to convert h is advantage. 27 . . . tDb8 28 tt:Jb6 'iie6 29 ii'a4! tt:Jb5 30 .l:!.d5 l::txd5 31 tt:Jexd5 Threatening 32 c4 tt:Jd4 33 'i*'xe8 ! . 31 . . . .l:!.d8 32 'ii'c4 �c6? 32 . . .

Zakharov - Dvoretsky Ordzhon ikidze 1 978 Black clearly has a great positional advan tage. When I ask, how he should continue in th is position , usual ly either 29 . . . .l:!.c2 or 29 . . .f6 and 30 . . . .l:!.c4 is suggested . And indeed , why not - seeing as Wh ite has no cou nterplay? But nevertheless, th ink how you would play if it were White to move. And then you wi l l fi nd an idea which promises qu ite good chances of a successfu l defence - the manoeuvre tt:Je5-g4-e3 with the a im of exchanging the mighty kn ight on d5 . This knight dominates the position , cementing together Black's queenside and making the rook at b5 a passive, inoperative piece . But Converting an Advantage ttJ 1 23 in the event of the kn ight exchange, the rook wi l l immediately be transformed - after a l l , i t is attacking the b6- and g5-pawns. It becomes clear what the best move is . 29 . . . h5 ! Black reta ins a l l the advantages of h is posit ion and prevents the opponent's on ly promising idea .

' The inherent a im wh ich a player should fol low when trying to convert an advantage is not to win as qu ickly as possib le . As yet no one has offered prizes for the smal lest number of moves. You should endeavour to play with the utmost safety, exploit ing a l l the resources of your posit ion and completely restrict ing the active possib i l it ies for your opponent. I t is not a misfortune i f you h ave to make an extra dozen moves on the board , if thanks to th is you make your task easier and reach your goal more su rely. In a sharp midd legame you may be tempted by the image of t iger, swiftly h u nt ing down its quarry and tearing it apart , but when converting an advantage in the endgame you should rather imitate a python , slowly suffocating its victim . The principle ' do not h u rry! ' was fi rst formulated (but not expla ined to a sufficient degree) i n instruct ional material on the endgame prepared by the Soviet master Sergey Belavenets . I n fact, beh ind th is brief formula are concealed various aspects of endgame techn ique, some of which we wi l l encounter in the fol lowing examples. 'Do not hurry!' does not imply that you can carelessly squander tempi. On the contrary, every opportunity to gain a tempo should definitely to taken into account and exploited. Leonhardt - Spielmann San Sebastian 19 12 One must possess great presence of mind, to not seize the booty immediately, but do this after several strong preparatory moves. The anticipation of victory often hinders the objection evaluation of a position. It is to this factor that I prescribe the loss of a half point in what was a very important game for me - the most annoying instance in my chess career. This was at the finish of the San Sebastian tournament of 1912, at a moment when I had excellent chances of winning first prize. For me it was sufficient to win against Leonhardt . . . (Rudolf Spielmann) . The game went: 46 . . . c;t>xd4? 47 g6 It transpires that Black is i n zugzwang . I should mention that here the zugzwang is 1 24 � Converting an Advantage mutual - any move by White worsens h is position . 47 . . . 48 l:td7 49 g7 'it>d3 d4 After advancing h is passed pawn to the 7th rank, Wh ite easily parries all his opponent's attempts . For example: 49 . . .

After 47 .l:!.c7+ 'it'xd4 Black captures the pawn with ga in of tempo, thanks to the attack on g5. S ince 48 .l:!.b7? .l::!.xg5 49 .l:txb4+ 'it'c3 is bad for Wh ite , he has to reply 48 .l:i.g7 . Now another tempo can be won by 48 . . .'it>c3 ! 49 ki.c7+ 'it>d3. Look at the posit ion after 50 ki.g7 : as yet Wh ite has not done anyth ing usefu l , whereas Black has e l iminated the pawn and placed his king on d3 . And yet, contrary to Spielmann's op in ion , even here he apparently did not have a win . For example: 50 . . . d4 5 1 g 6 .l:tc2+! ( 5 1 . . . b3 52 'it>b 1 ! , but not 52 �b7? b2+ 53 'it'b 1 .l:txg6 54 'it'xb2 'it'd2) 52 'it'b1 ! (52 'it'd 1 ? .l::!.c6 53 l:tg8 'it>c3 54 g7 Itc7) 52 . . . .Uc6 53 'it>b2!

If the opponent is deprived of counterplay, before changing the pattern of the play and initiating decisive action you should first strengthen your position to the maximum, by making all moves that are even slightly useful. Reti - Romanovsky Moscow 1 925 28 .l:!.c4! White is p lann ing 'it'f3 and e2-e3. It is very important that, after the black bishop moves, the c5-pawn remains en prise. It wi l l have to be defended by the rook, but then the white bishop wi l l occupy an active position on d5 , the k ing wi l l obta in the excel lent square e4, and the rook may be switched along the 4th rank to the kingside. 28 . . . 'iit>f8 29 'it>f3 30 e3 lieS .i.c3 It would have been better to play the bishop to b2. Converting an Advantage ctJ 1 25 31 a4! Method ical ly p layed ! This move does not come d i rectly into White'sp la n , but in itself it is usefu l - it is clear that the pawn stands better at a4 than at a2 . The opponent wi l l no longer have counterplay involving the switch ing of his rook to a6, and if Wh ite should somehow be able to capture the a 7 -pawn he wi l l obta in a passed a-pawn . I t is not clear whether these considerations wi l l p lay any role, but th is is not important . Any opportu nity to strengthen the posit ion even s l ightly should be exploited . 31 . . . �e7 32 �d5 l1c7 33 l:i.h4! The black king is ready to go to d6, defending the c5-pawn , and therefore there is no longer any point in keeping the rook at c4 . It is switched to the kingside to support the pawn offensive on that part of the board . 33 . . . h6 34 'it>e4 �f6 35 l1h5 Now Black must do someth ing , s ince g3-g4, h2-h4 and g4-g5+ is threatened . He should probably have played 35 . . . g6! 36 fxg6 (36 l:lxh6? ;t>g5) 36 . . . 'it>xg6 37 l1f5 a5! (prevent ing a4-a5-a6 fol lowed by l1f5-f2-a2-a5- b5). The outcome would have remained unclear, although Wh ite could have devel oped his i n itiative by h2-h4-h5+ and .Uf5- f1 -h 1 -h4-g4. I checked a pretty attempt to prevent the clos ing-up of the queen side by 37 a5? ! . The capture of the rook leads to an immediate mate: 37 . . . �xh5?? 38 Wf5 . Black has a d ifficu lt position after 37 . . . .l:td7 38 g4 .Ud6 39 .tc4 . U nfortunately, there is a spectacu lar refutation : 37 . . . c4 ! ! , and 38 dxc4? is not possible in view of 38 . . . 'it>xh5 39 �f5 e4 40 .txe4 .Uc5+. 35 . . . l1d7?! Pyotr Romanovsky tr ies to solve the prob lem by tactical means, but the combination he has prepared meets with a spectacu lar refutation . 36 g4 Of course, not 36 h4? g6 and the wh ite rook is trapped . 36 . . . 37 .Uxh6! 38 l1h7 g6 Wg5 �xg4 Now it is clear what Romanovsky had i n m ind . I n t he event o f 39 fxg6?? f5 or 39 �e6 fxe6 40 .Uxd7?? gxf5 White is unexpectedly mated . I f 39 f6 Black was intending 39 . . . �g5 . However, after 40 �xf7! �xf6 4 1 �xg6 .l:lxh7 42 �xh7 he most probably is unable to save the ending with opposite-colour bish ops. Wh ite attacks and captu res the a7- pawn (perhaps after fi rst playing h is bishop to c4) , after which one of the two passed pawns , a- or h-, is bound to decide the outcome. But with the pawn on a2 such an end ing would certain ly be drawn . Richard Reti found a prett ier and more convincing solution . 39 �e6! fxe6 39 . . . .l:te7 40 .l:lxf7 .l:lxf7 4 1 fxg6+ . 40 fxg6! l1d8 41 .l:lxa7 'itg5 1 26 Converting an Advantage 42 g7 43 a5 'it>h6 The passed a-pawn comes decisively into play.

In cases when one side's advantage is insufficient for a direct win, it makes sense to manoeuvre, without changing the pattern of the position, in order to set the opponent various problems, even if they are not too compl icated . And on ly when , after fai l ing to withstand the prolonged pressure , he blunders or makes some error, can you then turn to decisive action . Such tactics of sett ing the opponent an endurance test can sometimes a lso make sense in positions with a big advantage. By provoking h im into making a mistake , you can make it sign ificantly easier to convert your advantage. Mikhai l Botvinn ik remembers : In 1936 in Moscow during the 3rd Interna tional Tournament I witnessed the resump tion of the Capablanca-Ragozin game. The ex-world champion had an extra pawn and hence a won endgame. To my surprise, however, Capablanca did not undertake any positive action, but stuck to waiting tactics. Finally his opponent made an inaccuracy, and the Cuban won a second pawn and soon the game. 'Why didn't you immediately try to convert your material advantage?' I ventured to ask the great chess virtuoso. My companion condescendingly smiled: 'It was more practi cal to wait. ' Dvoretsky - Cooper Ph i ladelph ia 1 990 Wh ite u ndoubtedly has an appreciable positional advantage.

'i!Vh4 there fol lows simply 24 '.t>g2 and 25 lLlf3 . 23 . . . g5 24 '*'e3 h4 After 25 f4 !? the h4-pawn is , of course, doomed . But in th is case the wh ite k ing becomes somewhat exposed , which may g ive the opponent some counter-chances . For the moment I preferred not to change the pattern of the posit ion and I tried to ach ieve success in positional manoeuvring , by tying the black pieces to the defence of the weak g5-pawn . Especia l ly, s ince the possibi l ity of f2-f4 wi l l never run away. 25 ltJf3 'it>g6 26 'ikd3+ 'it>h6 Here I noticed that I could win a pawn by 27 'id2 (with the threat of 28 ltJxh4) 27 . . .

(see diagram) White has the advantage. But what is it better to play: 38 ..lkxd4 or 38 f6 ? When you have a choice between advan tageous positions with different material balances, all other things being equal you should choose the one in which the material balance is the most usual, the most standard. Here you will have more 1 28 � Converting an Advantage Dvoretsky - Baikov Moscow Championsh ip 1 972 experience and hence there is less chance of a mistake in the evaluation of the position or the subsequent play.

Moreover, on a more carefu l examination of the result ing position it becomes clear that the advantage has now passed to the opponent. The simple captu re on d4 is much safer. 38 �xd4 iVa4? 38 . . . ttlb5! was much stronger. In reply 39 �c8? does not work in view of 39 . . .

I saw it, of course, but I wondered whether it wouldn ' t be possib le to ach ieve even more . After noticing that 40 b3? is refuted by 40 . . . ttlxe5 , I for some reason completely forgot about the same possib i l ity in reply to 40 .l:Ie4 and I considered only 40 . . .'�xc2.

The situation has completely changed - Wh ite's position is absolutely hopeless, not on ly because of the opponent's extra pawn , but also in view of the dangerous position of the wh ite king. However, on the resumption I managed to confuse matters and save the d raw. I regarded my b lunder on move 40 as merely an inexpl icable 'eccentricity' . But when I showed the game to ex-world champion Tig ran Petrosian , he took a qu ite d ifferent view of th ings. 'How do you expla in why you avoided transposing into the endgame? You were in no doubt that it was won . But if you see an elementary solution , why then calculate variations and get involved in an exchange of blows?' The moral of this sad episode is obvious . Always give preference to the simplest way of converting your advantage, in which case the probability of a making a mistake will be minimal. Avoid unneces sary complications, and never play 'for brilliancy'. Converting an Advantage '2J 1 29 Any 'trifles', capable of facilitating the conversion of an advantage, should without fail be taken into consideration. If, for example , you do not have much t ime left to the t ime control , make use of every opportun ity to repeat moves. And after the time control has been reached , defin itely adjourn the game, if you have a winn ing position . I f you don't do th is , because of ti redness you may make a m istake and spoi l your position . This last p iece of advice has ceased to be topical i n view of the change in the rules of chess competitions - games are no longer adjourned . The fol lowing example is never theless sti l l instructive : it shows that over confidence in success, combined with a certain haste and inaccuracy, is capable of having a negative effect on the play of even such a player, deserved ly famed for his fine techn ique, as Anatoly Karpov. Karpov - Korchnoi World Championship Match , 22nd Game, Baguio 1 978 White's position is absolutely won . Karpov should have sealed h is next move , after which his opponent would probably not have bothered to resume the game. But for some reason the world champion made a few more moves at the board , and i n the end he squandered his entire advantage. 41 .l:l.xd6 lt:lxd6 42 .Jtc7?! Wh ite avoids the obvious 42 .l:txa4 because of the reply 42 . . . h5 , which of course, however, does not change the evaluation of the position . In pri nciple, the desire to find the most accurate way of exploiti ng your advantage is commendable, but in so doing you must accurately check the variations, which Karpov d id not do. I ncidenta l ly, a s imi lar mistake was made in h is commen tary by M ikha i l Tal , who recommended 42 .l:ld4 lt:lc8 43 .Jtc5 . I nstead of 42 . . . lt:lc8?

The princip le of two weaknesses This princip le is essentia l ly one of the consequences of the more genera l ru le of converting an advantage, which we have just been d iscussing - 'do not hu rry! ' . If the opponent is condemned to passivity, don't try to achieve success at one point alone - to hold it the defensive resources may prove quite adequate. Play more widely, and try to exploit weaknesses (and if possible - create new ones) on different parts of the board - then it will be much more difficult to defend.

But I wasn't quite able to complete the strategic picture - at the decisive moment I failed to display the necessary know-how. What was the prob lem facing Black? I will allow myself to quote Bondarevsky: 'White's pieces are tied to the weakness at c2, but a single weakness he is able to defend. Korchnoi was faced with the problem of starting play on the kingside, so as to create a new weakness in the enemy position. ' I realised that the move of the h-pawn appeared too routine to be the best. And 1 rejected 29 . . . g5 on account of the concrete variation 30 "illd2 f6 31 "ille1!, when White neutralises his opponent's advantage. But the best move- 29 . . . f5 (suggested by Flohr) completely escapedmy attention! The point of the move is not only that after the exchange on g4 White's f- and g-pawns will be further weakened; a/so of considerable importance is the fact that, after the ex change of queens, Black can create an outside passed pawn by . . . g7-g6 and . . . h6- h5. 29 . . . 30 'it>h2 31 hxg4 32 g5! h5? hxg4 g6?! Now a draw becomes the most probable result: the pawn position is fixed on both the queenside, and the kingside. (Korchnoi) . The game ended in a draw on the 51 st move. Exchanging Grandmaster Kotov remembered for a long t ime the advice g iven to him by the experienced master Vlad im i r Makogonov at the i nternational tournament in Venice in 1 950. Don't sharpen the play - what for? Ex change the queens, and arrive at a position where each side has a rook and two or three minor pieces left. Which piece should you exchange, and which should you keep? There are few modern players who can solve this question correctly. They under stand tactics, but in this you are superior to them. When try ing to convert an advantage you constantly have to th ink about the advisabil ity of this or that exchange. One of the most general gu ides is g iven by the fol lowing rule: Having a material advantage, the stronger side should aim to exchange pieces, whereas the weaker side should aim to exchange pawns.

It should be remembered , however, that the ru le we have just formulated is too genera l to be trusted uncond itional ly - in chess such universal laws do not exist. This is merely one of the gu ides; the concrete features of the position often d ictate a completely d ifferent course of action . Eh lvest - Andria nov Tal l i nn 1 98 1 The passed a-pawn promises Black defin ite counter-chances, but even so Wh ite's mate rial advantage should be sufficient for a win .

I nstead of the incorrect exchange, White could have activated h is k ingside pawns: 36 g4!? (threaten ing g5-g6-g7) . But it was safer fi rst to centra l ise the k ing : 36 f3 ! a4 37 'it>f2, and only then play g2-g4 . Such strategy would have been in accordance with a principle of endgame play, formulated by Aaron N imzowitsch : 'The advance must be a collective one/ '. V I . Lack of concrete action at the decisive moment Let us suppose that your opponent has no real cou nterplay and that you , i n accordance with the principle 'do not hurry! ' , are accumu lating advantages l ittle-by-l ittle . But against tenacious resistance by the opponent you wil l probably be unable to win the game by technique alone - at some point you wil l certa in ly have to switch from positional manoeuvring to the precise calculation of variations, and seek a concrete way to the goa l . Many players stumble at this point, with various factors playing their part. There is carelessness, ar is ing in anticipation of a qu ick win , about which we have a l ready spoken . There is the fu l ly understandable aim to act 'with every comfort' , not exces sively exerting yourself, and not subjecting yourself to the r isk of making a mistake in forcing play. There is the d ifficulty of deter m in ing that turn ing point , when you have Converting an Advantage ctJ 1 37 already extracted the maximum from play ing accord ing to the pr inciple 'do not h urry! ' , which means that i t i s t ime to find a concrete variation , one which exploits the advantage gained and advantageously changes the character of the play. I have noticed that bri l l iant positional players such as, for example, Salo F lohr or Anatoly Karpov, would successfu l ly convert an ad vantage against opponents i nferior to them in class. They manoeuvred , suppressed al l active possib i l it ies by their opponents , and when the latter fa i led to withstand the pressure , they made mistakes and them selves broke up their positions . But against opponents of equal class they often d id not manage to convert even a big advantage . For the reason that, when faced with tenacious resistance, you cannot afford to miss an appropriate moment for concrete and precise action , and this is by no means the strongest aspect of such positional p layers .

It wou ld be possible to expand further the store of typical ideas, but for a start it is sufficient to l im it ourselves to these, the ones most used . Some of the ideas mentioned operate not only in endings of the g iven type. Thus, for example, the rook should be placed to the rear of the more advanced pawn in nearly every case, when it is fight ing against two connected passed pawns. Alekhine - Tartakower Vienna 1 922 Alexander Alekh ine analyses the natural continuations 36 'it>c2 , 36 �c4. 36 g5 and 36 l:th2, and shows that they are sufficient for a d raw at best. There is only one way to win . 36 .ti.d5! ! White's fantastic move finds a precise explanation , from the standpoint of typical ideas for such endings. The variations springing from this rather unlikely move (it attacks one solidly de fended pawn and allows the immediate advance of the other) are quite simple when we have descried the basic idea: The black pawns are inoffensive: 1) When they occupy squares of the same colour as their bishop, for in that case White 's king can hold them back without difficulty, by occupying the appropriate white square, for example 36 . . .f2 37 l:!.d1 e4 38 'it;c2 j)_f4 39 �f 1 and 40 'it>d1. 16 w How to Study the Endgame 2) When the rook can be posted behind them, but without loss of time, for example 36 ... e4 37 'af5 Ji..g3 38 g5 e3 39 'ii.xf3 e2 40 .U.e3 (Aiekh ine) . I t makes sense to also examine endings which are closely l inked to those being stud ied . I n the g iven instance - sharp rook endings, transposing into endings with rook against pawns. In them we encounter ideas with which we are a l ready fami l iar. Alekhine - Bogoljubow World Championship Match , 1 9th Game, 1 929 In the game there fol lowed 70 .. .

'it>e4! The black king must be placed in the path of the opponent's k ing. Of course , we wi l l also meet new ideas which operate in sharp rook endings. The most important of them is inteference. We have a l ready encountered it in the analysis of the Mar6czy-Tarrasch ending. Now we wi l l examine a far more compl icated exam ple.

Thus we should bu i ld up our theory of the endgame in the most economical way, by s ing l ing out the most general ly used tech n iques and the most important exact posi tions. How best to ass imi late and consol i date this material is another matter. Here one cannot get by without a fami l iarity with addit ional examples, i nclud ing compl icated practical endings (such as the one we have just been ana lysing) . I t is usefu l to try and solve a series of tra in ing exercises on the g iven topic. And above al l , I recommend that you analyse i ndependently those endings which you happen to encounter. What does an i ndependent analysis of endgame positions g ive us? 1 ) We learn new ideas and methods, expandir;�g our system of knowledge, and we refine the information we a l ready have. 2 ) After analysing a large amount of mate ria l , we have a better u nderstanding of what featu res are typical and important and should therefore be i ncluded in the 'system' , and which are accidental i n character. As a result we form our endgame impressions most clearly, economical ly, at the same t ime without omitt ing anyth ing important. 3) I t improves our analytica l mastery. 4) At times some players ga in the impres sion that they largely u nderstand the secrets of chess and that to find the best move in the majority of cases is no problem . They only need not to b lunder, and to obta in the open ings they want. Analysis helps to rid themselves of such i l l us ions, and shows what an enormous wealth of ideas is sometimes concealed in the seemingly most modest position . I t guards against superficial ity, and a ids the development of such important tra its as precision , accuracy, industriousness, and so on . 5) An analysis of you r own games enables deficiencies i n you r play to be objectively diagnosed . 18 � How to Study the Endgame 6) AnalysisA serious mistake , after which Black fa l ls s ign ificantly beh ind in development and ends up in a d ifficult position .

Wh ite has an und isputed advantage . He is a pawn up , the black king is stuck in the centre , and the d7- and e6-points are obviously weak. But note that a l l these factors are not constant, but temporary. I magine that Black plays . . . bxc5 and . . . d7- d6 - then he wi l l consol idate h is position . This means that Wh ite must act swiftly and decisively. 1 6 li.d2? An instructive commentary on the move 1 38 � Converting an Advantage made by Flohr was g iven by grandmaster Isaak Boleslavsky: In this position could White really not find anything better than the strictly positional doubling of rooks? If White really wanted to play positionally, he should have continued 1 6 li:Jd4 ii..xc5 17 'ika4 ( 1 7 'ir'c1 !? - Dvoretsky), and to avoid the worst Black must exchange on d4. But the position demanded other measures, and after the energetic stroke 1 6 b4! White would have gained an irresistible attack. Here are some sample variations: 1) 1 6 . . .Chc6 17 cxb6 ( 1 7 l:td2 is a lso not bad - Dvoretsky) 17 .. . axb6 18 'ikb3 li:Jxb4 (if 1 8 . . . ii..xb4 both 1 9 c5 and 1 9 a3 are strong , and even 19 ii.xe6+ !

After the move made by White, the picture changes amazingly rapidly. I should also add that after 1 6 b4 ! li:Jxc4 the move 1 7 'ir'xa 7 is the strongest - 1 7 'i'b3 (hoping for 1 7 . . . b5? 1 8 ii.xe6+!

The entire game convincingly i l lustrates a wel l-known aspect of Ste in itz 's theory - the player with an advantage must attack, as otherwise he risks losing his advantage. I n th is clear formula the word 'attack' must be interpreted broadly - often it is necessary to find some precise variation , forcing combination etc. , i n short - a concrete and energetic way to exploit your advantage. Petrosian - Spassky World Championship Match , 1 2th Game, Moscow 1 969 23 l:.c1 A natura l move, reta in ing for White a serious positional advantage. I ndeed , the c6-pawn is weak, the knight has an excel lent square at c5 , and the bishop at h5 is out of play. But couldn't Wh ite have played more accu rately - 23 i.h3 ? After a l l , after 23 . . . l:.b7 24 l:tc1 .l:.c7 compared with the game White has ga ined a tempo - he has brought out h is b ishop to a more active position . I f instead 23 . .

I n the event of 2a . . . .te4 29 .txe4 dxe4 30 �f2 Black's position is hopeless in view of the weakness of h is c6- and e4-pawns.

Wh ite also had another promising possibi l ity: 27 tt:'lc3!? , emphasising the vulnerabi l ity of the opponent's centra l pawns . The idea of g3-g4 and f3-f4 could have been put i nto effect sl ightly later. 27 '.t>f2 f6!? 28 e3?! Petrosian continues strengthening h is posi tion , but now his advantage is somewhat reduced , s ince the black bishop is included inthe defence of the queen side pawns . But meanwh i le White sti l l had a concrete way of achieving a won position : 2a tt:'lc5 ! .l:!.e7 (or 2a . . . a5 29 tt:'le6 l:!.cca 30 .th3 with the unavoidable 31 tt:'ld4) 29 tt:'la6 .tea 30 a4! tt:'ld6 31 e4, and Black loses a pawn . 28 . . . .tf7 29 .tf1 30 l:!.c3 tt:'ld6 30 .ta6!? came into consideration . 30 . . . �f8? A far from obvious mistake . Black should have taken control beforehand of the impor tant f4-square , by playing 30 . . . g5 ! . After 3 1 tt:'lc5 a 5 3 2 l:!.dc1 .l:te7 fol lowed b y . . . .tea it would not be easy for Wh ite to strengthen his position . 31 tt:'lc5 a5 32 l:!.dc1 .l:!.e7 33 .th3 Wh ite has prevented the important defen- sive move 33 . . . .tea (34 tt:'le6+ and 35 tt:'ld4) and created the threat of 34 tt:'ld7+ . 33 . . . .Uaa7 B lack is only just hold ing on . One senses that it is time to find a concrete way to break through the opponent's defences. And there is such a way. After 34 tt:'ld3 ! .tea 35 .!Llf4 White is threaten ing both 36 tt:'le6+ fol lowed by 37 tt:'ld4 or 37 tt:'lda , and 36 l:!.xc6 .txc6 37 tt:'lg6+.

However, we nevertheless do not have the right to say that Wh ite's position is defin itely won . Even in a seemingly d ifficult situation one can usual ly find resources , enabl ing defeat to be avoided or at least the opponent's task to be s ign ificantly compl i cated . That is a lso the case here . For example, there is a clever exchange sacri fice : 35 . . . l:!.a6 !? 36 tt:'le6+ l:!.xe6 37 .txe6 f5 3a g4 g6 39 gxf5 gxf5 40 .Ug 1 �e7, and the unfortunate position of White's bishop means that t he conversion of h is material advan tage is problematic. I nstead of 36 tt:'le6+, i t is probable that 36 a4! is stronger - subse quently the knight may be switched to d4 not only via e6, but also via e2. Converting an Advantage lZJ 1 4 1 Often the best defence is active defence. I recommend checking 35 . . . a4 ! . Here is an approximate variation : 36 .:.xc6 .i.xc6 37 t:Llg6+ (37 l:txc6 axb3 3a axb3 .l:.a2+ 39 'i!tg 1 :xe3) 37 . . .

For the moment the outcome of the game remains unclear - B lack's counter attacking resources should not be under estimated . Even so, the manoeuvre of the knight to f4 was the correct p lan . Petrosian played a weaker move . 34 a4?! The position can be unhurriedly embel l ished , if during this time the opponent is not able to do anything to strengthen h is defences. This is not the case here. I t is dangerous to abuse the principle 'do not hurry! ' . Apparently Petrosian was i ntending 35 tiJd3 .iea 36 CiJf4 'i!tf7 37 tiJe2 fol lowed by CiJd4 and he wanted to prevent the opponent from replying 37 . . . tiJb5. Genera l ly speaking , it is usefu l to fix the black pawn on a5 and to deprive the knight of the b5-square . But if th is is played , it should be after the switching of the kn ight to f4 , and therefore now Boris Spassky forestal ls the main danger. 34 . . . g5 1 The f4-square is taken u nder contro l . 35 l:.d1 An exchange sacrifice came i nto considera tion - 35 tiJd3 .tea 36 .llxc6 .i.xc6 37 llxc6 tOea 3a tiJc5 .

On the resumption the game ended in a draw. Transformation of an advantage The best way of exploit ing an advantage sometimes i nvolves a favourable change in the character of the position , giving up some advantages that you a l ready have in favour of others . Such a method is ca l led 'transfor mation of an advantage' . Taimanov - Stein 34th USSR Championsh ip , Tbi l is i 1 966/67 Black has a great positional advantage. He has securely blocked the opponent's central pawns, the bishop at g2 is 'bad ' , and the wh ite knight a lso lacks mobi l ity. The most natu ra l p lan , which Leonid Stein undoubt edly had in m ind , i nvolves the advance of the queenside pawns. 1 42 � Converting an Advantage 26 'it>f1 White intends to reinforce h is centra l pawns by taking h is king to e3 and if necessary placing h is bishop on f1 . H is rooks would then be freed to take action against Black's queenside pawn offensive. At this moment it probably seemed to Stein that the conver sion of h is advantage by normal methods would not be so easy. If the opponent makes an unexpected move, hindering the implementation of your plans, it is useful to ask yourself: 'What may be the drawback to the opponent's move?' But even after asking yourself such a question , it is not easy to come to the decision found by Stein - it is very much not in keeping with the unhurried character of the preced ing play, and with Black's intended plan . 26 . . . f5 !? By opening the f-fi le , on which the wh ite king stands for a moment, Black creates a th reat to the d3-pawn . Of course , such a move , freeing White's bishop and knight , could only be made by a h igh ly dynamic, non routine player. 27 exf5 �xf5 28 'lt>e2 I would have preferred to part with a pawn immediately, by returning with the king to g 1 . 28 . . . lbg4!

Petrosian - Bann ik 25th USSR Championsh ip , R iga 1 958 Wh ite unexpectedly offered an exchange of bishops. 1 8 it.c5! Why? Here is Petrosian's explanation : Before deciding on this move, i t was essential to thoroughly weigh up everything 'for ' and 'against'. It looks illogical, since White voluntarily exchanges his 'good' bishop for the opponent 's 'bad ' bishop, instead of exchanging it for the knight (1 8 ..txb6+) and consolidating his advantage. But on a deeper investigation of the position it be comes clear that after the possible ex change of rooks on the d-file and the transfer of his king to e6, Black covers his vulnerable points and sets up an impregna ble position. In this case his 'bad' bishop would play an important role. For my part I should comment that after 1 8 g4 .l:xd 1 + 1 9 l:txd 1 l:td8 20 l:txd8 'it>xd8 2 1 it.xb6+ axb6 22 Wc2 White a lso reta ins excel lent chances of success.

Lothar Vogt cou ld have exchanged either the rooks , or the bishops. Try to estimate ( I mean estimate - to ca lculate everything is not possible and you have to trust your i ntu ition ) whether one of the exchanges (or both) offers real istic chances of saving the game. If you r answer is positive, th is g ives grounds for seeking an a lternative move to the one chosen by White in the game. F i rst let us examine the bishop ending: 33 . . J:te8 34 ltxe8+ i...xe8. In the magazine 64 - Shakhmatnoe oboz renie ( 1 996 No. 1 2) , grandmaster Igor Zaitsev suggested a clever breakthrough plan : 35 b4! ? b6 (Black loses immediately after 35 . . . axb4? 36 aS or 35 . . . i...xa4? 36 bxa5 fol lowed by 37 i...xb7) 36 b5 i...f71 ( it is important to forestal l Wh ite's main threat c4-c5) 37 �d2 �g7 38 �d3 , restricting 1 50 � Converting an Advantage himself to the variation 38 . . . h6 39 c4 'it>f6 40 c5 'iite5 41 cxb6 'iitd6 42 'iite3 �b3 43 �c6 �xa4 44 b7 'it>c7 45 b6+ 'iitb8 46 �xa4 . Here I do not agree with h im - Black's resources are not yet exhausted . To say noth ing of the attempt, by sacrificing the h7- pawn with 38 . . . 'it>f6 , to bring the king to the queenside as qu ickly as possible in order to h inder c4-c5, he can also play more accurately in the course of the plan exam ined by Zaitsev. 38 . . . h5 39 c4 'iitf6 40 c5 'it>e7! (but on no account 40 . . . 'it>e5? - the place for the king is not in the centre, but in front of the pawns) 41 cxb6 'iitd8 ! . How can White win here? I t is not possible to queen a pawn : 42 �f5 �b3 43 'iitd4 �xa4 44 'it>c5 �d 1 45 �d6 �f3 - the bishop has arrived just in t ime. And the position arising after 42 'it>e3 �b3 (42 . . . 'it>c8) 43 �c6 'it>c8 44 b7+ 'it>b8 45 b6 .ii.d 1 is drawn . The main continuation is 35 �xb7 �xa4 36 c4. Black avoids an immed iate loss by playing 36 . . . i.b3 37 c5 �g7 . If 38 c6 , then 38 . . . i.d5! 39 �a8 �e6 ! . I n the event of 38 'iitd2 'iitf6 39 'iitc3 Black finds the excel lent manoeuvre 39 . . . �d 1 ! with the idea of . . . i.f3 . I t is not apparent how White can win . For example, after 40 c6 �f3 4 1 'iitc4 h 5 4 2 �a8 �e7 4 3 'it>b5 i t i s bad to play 43 . . . 'it>d6(d8)? 44 «t>b6 h4 45 c7 or 43 . . . h4 44 gxh4 g3? 45 c7! (now it is clear why the king avoided the d4- and c5-squares - so that after 45 . . . g2 the pawn should not queen with check), but Black continues 43 . . . h4! 44 gxh4 «t>d6! , l u ring the king to b6 where it wil l be checked , and then 45 . . . g3 (analysis by Zaitsev) . I n the event of 38 �c8 ! Black has two possib i l it ies: a ) 38 . . . h5 39 c6 h4 40 gxh4 g3 41 �h3 �e6 42 �g2 'it>g6 43 �d2 �h5 44 'it>e3 'it>xh4 45 'it>d4 'it>g5 46 Wc5 �f4 4 7 'it>b5 'it>e5 (after 47 . . . 'it>e3 48 'it>xa5 Wf2 49 �h 1 the king does not manage to return to the queenside in time) 48 'it>xa5 'iii>d6 49 b4 , and White should apparently win . b ) 38 . . .f6 39 i.xg4 'it>e5 ( in th is way, i n Zaitsev's op in ion , B lack ga ins a draw) 40 'it>d2 Wd5 4 1 'ito>c3 i.a2 42 b4 axb4+ (or 42 . . . «t>c6 43 i.f3+ 'ito>b5 44 �e2+ 'ito>c6 45 bxa5 'ito>xc5 46 'it>d2 ) 43 'it>xb4 'ito>c6 44 .ii.f3+ 'ito>c7 45 'it>c3 , and there is noth ing to be done against the decisive breakthrough of the king to the king s ide. And th is means that the exchange of rooks most probably would not have saved Black. How can the defence be improved? The best saving chances i n such situations are usual ly promised by transposing into a rook ending (everyone knows the saying : ' rook endings are never won' ) . And so, 33 . . . �xe4!? 34 .l::txe4 . However, after 34 . . . .l:!.g8? (34 . . . h5? 35 l::te5) 35 Wd2 !? with the idea of 'it>e3-f4 Black is condemned to complete passivity and should certain ly lose. In rook endings you should aim to activate the rook. After 34 . . . .l::tf1 + 35 'it>d2 .l:!.f2+ 36 Wd1 (36 �d3 .l::tf3+ 37 .l::te3 .l::tf2 38 b3 'it>g7) 36 . . . h5 ! 37 .l::te5 .l::th2 38 .l::txa5 'it>g7 fol lowed by . . .

There is a lso another way of transposing Converting an Advantage LtJ 1 51 into a rook end ing : 33 . . .l:tf1 + 34 �d2 l:tg1 35 i..xc6 bxc6 36 l:txa5 l:tg2+ 37 'it>d3 l:'l.xg3+ 38 �e4, and now either 38 . . . l:tg 1 39 l:'l.c5 .Uf1 !

(4 1 . . . �f1 would appear to be worse : 42 I:tg5 c5 43 l:'l.xg3 .Ua 1 44 '.te4 I:txa5 45 'it>d5 , and Wh ite is threatening 46 c4 fol lowed by 'it>c6-b6) 42 a6 l:f.f1 , and the position is most probably drawn . I n the rook endgame Black would have retained good drawing chances. This factor casts doubts on the p lan beg inn ing with 33 ..ie4 , and forces us to seek other ideas. Here is a suggestion by grandmaster Viorel Bologan . 3 3 .Ug5! I n the fi rst instance , as we know, 33 . . J:U3 must be prevented . 33 . . . �xa4 34 I:txa5! An unexpected change of d i rection ! I n h is commentary Smirin considered only 34 l:'l.xg4 �c6 with a probable draw. 34 . . . �c6 34 . . . �e8!? would seem to be more tena cious , aiming at the fi rst conven ient opportu n ity to play . . . h7-h5 . 35 �g5! The rook resembles an annoying fly. 35 . . . �f3 35 .. ..!:!.g8 36 l:f.h5 is no better. 36 l:f.h5 The immediate 37 'it>d2 !? �f6 38 b4 is also good . 36 . . . 37 �d2 I:tf7 After ski lfu l ly tying down the enemy pieces , White now wants s imply to strengthen h is position by advancing h is queenside pawns. I n reply to 37 . . . �c6 noth ing is g iven by 38 b4 .i::tf2+ (but not 38 . . . .Uf3? 39 b5) 39 �e 1 �g2 40 b5 �f3 41 .Uxh7+ 'it>g8, but 38 �h4! is not bad . Such a p lan for convert ing an advantage (domination and the absence of cou nterplay for the opponent) is fu l ly i n the spirit of Anatoly Karpov. From the viewpoint of the practical player, it is very important that here practical ly nothing needs to be ca lculated ( in contrast to the 33 �e4 variation , where one has to delve both into the b ishop, and the rook endgame), and this means that the probabi l ity of mistakes is reduced . I ncidenta l ly, the fina l conclusion about there being on ly one solution to the in it ia l end game position (and a lso about there being only one winn ing method in the bishop ending) is fu l ly i n accordance with Zaitsev's view: My many years' experience of analysis have convinced me that in tense, balanced positions there cannot be two ways to win. The same thought was a lso expressed by another experienced analyst, i nternational master Gavri i l Veresov: In positions on the border between a draw and a loss, we normally find there is only one solution. 7 . Smyslov - Botvinnik (World Champion ship Match , 3rd Game, Moscow 1 954) Although Black has three pawns for a piece, his position is d ifficult. Vasi ly Smyslov could have decided the outcome in the middlegame, by breaking up the opponent's pawn cha in and open ing l ines for h is p ieces by h2-h3. 27 Wkg2!

Here the game was adjourned , and the players agreed a draw without resuming . 8. Dvoretsky - Zilberstein (Ordzhonikidze 1 978) To where should the rook move , e2 or d 1 ? But isn't it a l l the same - after a l l , i n both cases White remains a sound pawn to the good? But you should not approach the conversion of an advantage so frivolously - otherwise very often disappointment wi l l await you . You should try to d iscover the d ifference between moves and choose the one which is in some way better, more accurate than the other. If 26 l:!.e2 there fol lows 26 . . . �c8 , when 27 .l::!.e6 .l::!.c2 is pointless . Having an obvious advantage, you don't want to compl icate the play and weaken your queenside pawns by 27 a3 i..f8 . The normal continuation is 27 g3 Wf7. We note that the black king prevents our rook from becoming active on the e-fi le, whereas the black rook on the c-fi le , a long way from the wh ite k ing , is very active and it restricts the wh ite pieces . I myself wanted to seize the c-fi le , Therefore I began checking 26 l:td 1 . 26 �d1 ! 'it>f7 Black hardly has the right to sacrifice a second pawn by 26 . . .

Now 27 . . . i..d2 is poi ntless in view of 28 .l:!.c7+ and 29 g3. White wants to calmly strengthen h is position by g2-g3, l:!.c2 , and Wg2-f3 ; his rook is constantly th reatening to break into the opponent's position along the c-fi le .

'it>d6? 40 e5+ does not help , and therefore the reply 39 . . . l:.d8+ is forced . After 41 'it>c3 the threat of c4-c5 has become more serious, s ince now the c5-pawn may be defended by the king .

It remains to verify 39 h4. The reply 39 . . . .l:!.h8! suggests itself (39 . . . f5? 40 exf5+ is bad for Black). Wh ite plays 40 g3, preparing 41 l:!.h2 and 42 g4 . How can th is p lan be countered?

We have establ ished that White does not ach ieve anyth ing with the d i rect implemen tation of any of our intended plans. How can he nevertheless continue playing for a win?

It is s ign ificant that Jose Raul Capablanca a player with bri l l iant i ntuit ion - was unable to come to the correct decision , suggested by Alekh ine - a player with a tota l ly d ifferent way of th ink ing . A move such as 39 h3 ! ! cannot be cal led intu itive , based on 'general considerations' - it cou ld be found only after a deep and very concrete penetration i nto the secrets of the position . Many years ago I was help ing Botvinn ik by giv ing some lessons at h is schoo l . On one occasion , at the request of Mikha i l Moisee vich , I prepared an extensive endgame lesson for the young Garry Kasparov, which included in particular an independent analy s is of the Capablanca-Aiekhine ending. Garry found another way of foresta l l ing the switch ing of the black rook to the 5th rank the move 39 g3! ! . It appeals to me perhaps even more than Alekh ine's recommenda tion , s ince it conta ins an add itional active idea : 40 h4 ! . And there do not appear to be any drawbacks : for example, if 39 . . . g5 there Lessons from One Particular Endgame ctJ 1 6 1 i s a pleasant choice between 4 0 h 4 a n d 40 l:.f2 with the threats of 41 .l:.f5 or 4 1 d4? c5+ . 42 . . . f6! The main danger has been e l iminated - if 43 g4 there is the reply 43 . . . g5+ ! . The play takes on a manoeuvring character. Capa blanca ski lfu l ly sets his opponent one problem after another, so that Alekh ine is required to defend with exceptional care . 43 l:tc2 l:f.e5 Otherwise after 44 c5 the rook would have been cut off from the kings ide and would no longer have been preventing White from playing g3-g4 and h4-h5 . 44 c5 A double-edged move , but otherwise the position cannot be strengthened . Wh ite restricts the mobi l ity of the enemy rook , but his own rook wi l l be tied to the defence of the c5-pawn. 44 . . . l:th5 45 l:.c3 Threaten ing an exchange of pawns advan tageous to White : 46 lta3 l::txc5 47 l:.xa7. 45 . . . aS! 46 .l:.c2 l:te5 47 l:lc3 l:1h5 48 g7! Wh ite's subtle manoeuvres have forced the black king (which is obl iged to control the g6-square) to move away from the centre . Capablanca sees that the most appropriate moment for transforming h is advantage has arrived . He g ives up h is extra pawn , but activates h is rook to the maximum and drives the opponent's k ing onto the back rank . 51 .l:td4!

I n Alekhine's opin ion , Black is able to hold the position , but at any event he would have had to defend accurately.

With what topic should the ending of the Capablanca-Aiekhinegame be l inked? Af ter a l ittle thought you wi l l see that there is no clear answer - in the process of studying the ending various aspects have come to l ight, identica l ly important for the practical player. Let's remember what we have seen: 1 ) Excellent example of a practical rook endgame. Among the numerous evalua tions and methods typical of this type of ending , with which the two players operated , I wi l l s ingle out a comparatively less trivial idea , which is very clearly expressed here. An open l ine , for wh ich a rook should a im , may be not only a fi le , as usua l , but sometimes also a rank . 2) Model example of accurate defence. I t is i nstructive to fol low how Alekh ine, without losing his presence of mind in a d ifficu lt situation , move by move patiently resolved the problems facing h im . 3) Various aspects of the problem of converting an advantage. Here we can mention : the importance of looking for and foresta l l ing the opponent's cou nter-chances (at the very start of the ending) ; the maximum strengthening of Wh ite's position before changing the pattern of the play; the timely transformation of an advantage (the Lessons from One Particular Endgame lZJ 1 63 5 1 st move) ; fi nal ly, the need at some point (the 56th move) to abandon positional manoeuvring and choose a concrete course, involving precise calcu lation . 4) Demonstration of the importance of prophylactic th inking. Without it, of course, it is not possible to find the bri l l iant solution to the position on the 39th move . And subsequently too Alekh ine's defence was based on taking account of al l the oppo nent's active plans and forcefu l ly opposing them. 5) Grounds for reflection about chess players with an intu itive way of th inking. We have seen which decisions are d ifficult for them or a ltogether inaccessib le . The conclusion suggests itself, that even if you possess splendid intuition , you should de velop in yourself the abi l ity to constantly delve into the concrete deta i ls of the position and if necessary to accurately ca lculate variations . For a chess player it is very important to evaluate objectively the strengths and weak nesses of a forthcoming opponent. A source of such evaluations is provided by an analysis of games played by h im. Some of them wi l l prove especia l ly i nformative. I n the 1 920s Alekh ine was preparing for h is due l for the world crown against Capablanca . This is what he recorded for h imself after the New York tournament of 1 924: I took home with me from this tournament one valuable moral victory, and that was the lesson I learned from my first game with Capablanca, which had the effect of a revelation on me. Having outplayed me in the opening, having reached a won position in the middlegame and having carried over a large part of his advantage into a rook ending, the Cuban then allowed me to neutralise his superiority in that ending and finally had to make do with a draw. That made me think, for Capablanca had cer- tainly been trying very hard in this game, so as to draw nearer to Dr. Lasker, who was in the lead, and who had won against me the previous day. I was convinced that if I had been in Capablanca 's position I should certainly have won that game. I had finally detected a slight weakness in my future opponent: increasing uncertainty when con fronted with stubborn resistance! Of course I had already noticed Capablanca committing occasional slight inaccuracies, but I should not have thought that he would be unable to rid himself of this failing even when he tried his utmost. This was an exceedingly impor tant lesson for the future! Later, in a famous a rticle 'The 1 927 New York tou rnament as a prologue to the battle in Buenos Aires for the world championsh ip ' , Alekh ine once again emphasised the ro le that the game with Capablanca had played for h im : This game, incidentally, was the starting point for my understanding of Capablanca 's chess individuality. I wi l l a lso g ive some other assessments by Alekh ine of the style of h is h istoric oppo nent, wh ich are confi rmed by the ending we have examined . They may seem exces sively sharp, but to some extent th is is expla ined by the very tense personal rela t ions which developed between the two champions. But objectively these assess ments seem to me to be just (of course, only 'on a grand scale' - taking i nto account the very h igh standard of play in question) . . . . Capablanca is by no means an excep tional master of the endgame; his skill in this stage of the game is mainly of a technical character and other masters in certain fields of the endgame surpass or used to surpass him (for example, Rubinstein in rook end ings). . . . In Capablanca's games with the years one observes increasingly less delving into 164 � Lessons from One Particular Endgame the details of the position, and the reason for this is his unshakeable (I am talking all the time about the period before Buenos Aires) confidence in the infallibility of his intuition. The saddest thing for Capablanca is that this system of his of operating with 'good' moves almost without exception proved sufficient, since to a great extent he was opposed in the positional sense by a more or less helpless weapon. On account of this 'lack of punishment' in employing not the best moves, he, on the one hand, got out of the habit of that concentration of thought during a game, which alone can give a guarantee against possible elementary oversights, and on the other hand- his self-confidence grew immeasurably and turned almost into self worship . . . ltJ 1 65 Mark Dvoretsky G randmaster Tech n i q ue I n August 2005 I gave a lectu re in the London Chess Centre and showed the fol lowing position , taken from the magazine 64 Shakhmatnoe obozrenie - the ending of the game was publ ished there with notes by the winner Evgeny Najer.

In th is way Black solves his opening problems - in fact, it is now h is opponent who has to act carefu l ly, to avoid getting into d ifficu lt ies. 12 exd5 ( 1 2 e5 is dubious in view of 1 2 . . . tt:leB 1 3 tt:lxd5 e6 1 4 tt:lc3 .1Lxe5) 1 2 . . . tt:lxd5 1 3 tt:lxd5 e6 14 .i.h6 exd5 1 5 .1Lxg7 'it>xg7 1 6 cxd5 ( 1 6 tt:lb5!?) 1 6 . . .

And in genera l , looking in a computer database, I saw that in most of the games where th is variation occurred there was effectively no play - the contestants agreed a draw somewhere between the 1 1 th and 23rd moves. 1 66 � Grandmaster Technique In the summer of 2003 I publ ished an article in the Russian newspaper Shakhmatnaya nedelya and on the Chesscafe site (it was also publ ished somewhere else on the I nternet) with a suggestion that a ru le should be introduced forbidding conversations be tween players during play and , hence, premature draw agreements . Two years later my suggestion was successful ly adopted at the super-tournament in Sofia . Its un iver sal adoption would , I am sure, not only lengthen games, butalso lower the percent age of draws. As we wi l l now see , even in such a qu iet and seemingly l ifeless situa tion , where a draw is indeed the most probable outcome, it is possible to seek resources and pose problems for the oppo nent. 17 .. .'it'e5 1 8 'it'd4 tt:Jc6 1 9 'if xeS+ tt:Jxe5 20 �ac1 We have reached the position in the fi rst d iagram. The at fi rst sight mysterious move found by grandmaster Najer is the strongest - it was thanks to it that he won the game. 20 . . . b6! ! Let us try and reproduce Black's logic. F i rst he probably checked 20 . . . tt:Jd3 and real ised that after 21 .l:r.xc8 .l:r.xc8 22 .l:r.d 1 the position was equa l . Then h is attention was drawn to the possibi l ity of 20 . . . .l::.xc1 21 �xc1 �d8 with the idea of 22 . . . �d2 . Najer is an experienced player and he knows that in the fi rst instance you must check active repl ies by the opponent - in the given case 22 �c7 . There appears to be noth ing better than 22 . . . .l:r.d2 23 �f2 .l:r.xa2 24 .l:r.xb7, but here Black's advantage is of a purely academic natu re, and he has practica l ly no chances of success. As was confi rmed by the game Li Ruofan-Rowson , 2004 . But after . . . b7-b6 in this variation Black would remain a pawn up, s ince from a2 his rook defends the a7-pawn . 21 .l::tfd1 ? ! After the game Valery Yandemirov sug gested that he should have played 21 f4. Of course, advancing the f-pawn is not some th ing that one wants to do - one can decide on this move only after employing prophy lactic th inking and clearly appreciating the danger threaten ing White. 21 . . . 22 .l:r.xc1 .l:r.xc1 .l:r.d8 Now after 23 �c7 .l:r.d2 the only way of avoid ing the loss of a pawn is 24 tt:Jc3 (bad is 24 tt:Jc1 ?? .l:r.d 1 + 25 �f2 �xc1 ) , wh ich al lows the unpleasant pin 24 . . . .U.c2 . The situation after 25 tt:Jb5 .t!.xa2 26 �xa 7 �b2 looks dangerous for Wh ite: the b3-pawn is under attack, and he has to reckon with the manoeuvre . . . tt:Jd3-f4(e 1 ) . He shou ld probably have restricted h imself to the accurate move 23 .l:r.c2 . But one does not want to place the rook passively, especia l ly s ince after 23 . . . .l:r.d 1 + 24 'it>f2 tt:Jd3+ the king has to be moved to the side - 25 'iitg3 , s ince in the event of 25 'it>e3?! tt::le1 26 .l:r.c7 tt:Jxg2+ 27 'it>f2 .U.d2 28 .t!.xa7 ctJf4 29 'it>e3 .l:r.xe2+ 30 'it>xf4 l:!.xh2 White comes out a pawn down . It is qu ite probable that after 23 �c2 , and perhaps also after 23 l:!.c7 , the position would objectively have remained drawn . But it is one th ing to calmly analyse at home, Grandmaster Technique ttJ 1 67 and with the aid of a computer, and qu ite different to take a decision at the board . A forced draw is not apparent, defending is unpleasant - in such a situation it is easy to lose your bearings. 23 tt::lc3? A serious mistake! Wh ite wants to exchange the rooks, but fa i ls to take account of the fact that the black k ing wi l l be the fi rst to reach the centre . In a knight ending a more active king is a very important factor. 23 . . . �d2 24 .Ue1 ?! Obviously, when he made h is previous move , Wh ite was intending the manoeuvre .l::!.e 1-e2 . Of course , the enemy rook on the 2nd rank cannot be tolerated , but he should have exchanged the rooks in a sl ightly more favourable way: by 24 �f1 (with the same idea : �e 1 -e2) 24 . . . tt::ld3 (24 . . . f6? 25 tt::le4) 25 .l:td 1 .l:txd 1 + 26 tt::lxd 1 �f6 27 tt::lc3 �e5 . I n the game this same position was reached with Black to move . White can make use of h is extra tempo by playing 28 g3 (28 'it>e2 is evidently weaker: 28 . . . tt::lf4+ 29 �f2 a6 30 g3 'it>d4! 31 tt::le4 l2Jd5) . But here too Black has a pleasant choice between 28 . . . a6 29 'it>e2 'it>d4 30 Wd2 tt::le5 31 tt::le2+ �c5 32 �e3 �b4 and 28 . . . �d4!? 29 tt::lb5+ �c5 30 tt::lxa7 tt::lc1 31 �e1 tt::lxa2 32 �d2 tt::lb4 (and 33 . . . tt::ld5) with an appreciable advantage. 24 . . . tt::ld3 25 .Ue2 26 tt::lxe2 27 tt::lc3 28 �f1 l:txe2 �6 'it>e5 a6 From the previous note it fol lows that 28 . . . �d4 was also possib le, but in th is situation the move in the game is , of cou rse, more accurate . 29 �e2 30 �d2 tt::lf4+ If 30 �2. then 30 . . . �d4 is strong, as is the suggestion of Carsten Mu l ler: 30 . . . f5 !? , and if 31 g3? �d4 ! . 3 0 . . . 3 1 tt::la4 32 'it>e2 33 tt::lc5 33 . . . tt::lxg2 tt::lh4 b5 a5! Najer was not satisfied with the variation 33 . . . �f4 34 tt::lxa6 tt::lxf3 35 tt::lc7 tt::lxh2 36 tt::lxb5, i n which the play becomes sharper. I n advancing h is a-pawn he undoubtedly foresaw the tactical subtlety on the fol lowing move , which sign ificantly faci l itates the conversion of his advantage . 168 Grandmaster Technique 34 a4 'it>d5! I n this way Black ensures the safety of h is important a5-pawn . 35 tt:Jb7 'it>c6 36 tt:Jd8+ 36 tt:Jxa5+ Wb6 37 b4 bxa4 was completely hopeless for Wh ite . 36 . . .

I t was pleasant for m e to read the fol lowing comment by Najer about the move 20 . . . b6 ! ! : A useful move, from which one can identify a pupil of Mark Dvoretsky or at least a careful reader of his books. Evgeny Najer twice participated in my tra in ing sessions and has stud ied my books - obviously, his work has not been in va i n . I th ink that the grandmaster's comments were evoked by the close s imi larity of this ending with one of the examples g iven in my book School of Chess Excellence 3 - Strategic Play, which I should now l i ke to show you . (see diagram) Black's positional advantage is determined by the active placing of his pieces. But it is rather frag i le : the sl ightest inaccuracy, and it wi l l evaporate . Which is what happened in the game: 28 . . . h5? 29 '.tc1 ! l::tf5 30 l::txf5 tt:Jxf5 31 tt:Je4 g4 32 tt:Jc5+ We5 33 tt:Jxb7 tt:Je3 Draw. A very important principle in the conversion of an advantage is the maximum restriction Stean - Hort Biel 1 98 1 of the opponent's possib i l it ies, and the suppression of any cou nterplay, any useful operations a imed at improving his own position . To put th is pr inciple successfu l ly i nto effect, use must be made of 'prophylac tic th ink ing ' . Let us ask ourselves what White wants to play. H is choice is l im ited . There is no point in attacking the kn ight : 29 �d2 lle1 + 30 'it>b2 �e5. Obviously the only sensible operation is to bring the k ing to the centre : �b1 -c1- d2-d3 . I t is th is that shou ld be prevented . 28 . . . l::te 1+ ! 29 'it>b2 h5 Grandmaster Technique ltJ 1 69 Having foresta l led the opponent's i ntention , Black can now calmly strengthen h is posi tion . I t is not easy for Wh ite to defend. For example, if 30 �f8 there fol lows 30 . . . .l:!.g 1 3 1 .!:!.f2 �e5 32 ll'le2 � e 1 33 ll'lxd4 'i£txd4, and the dominating position of B lack's king guarantees h im a great advantage in the rook ending . But a completely d ifferent interpretation of the position is a lso admissible. The black king is far more active than its wh ite opponent, which can be especial ly percepti ble in a pawn or knight ending (Mikha i l Botvinn ik once remarked : 'A knight end game is the same as a pawn endgame' ) . Artur Yusupov suggested 28 . . . .l:i.f5 !? . Wh ite repl ies 29 �xf5 (29 �d2 .l:i.f1 + 30 �b2 '.te5 is unfavourable for h im) .

Once when I was looking through Chess lnformator, an ending annotated by one of my pupi ls , Alexey Dreev, caught my eye.

U nfortunately, th is entire variation is a comedy of errors , at the basis of wh ich is Dreev's natura l , but in the g iven instance incorrect striving to defin itely place his rook behind the opponent's passed pawn . After 9 g5 B lack saves the game by 9 . . . l:th 1 ! (the place for the black rook is to the rear of the more advanced pawn) 1 0 g6 llh5+!

In 1 976 the USSR Championship was held in Moscow. I n the very fi rst round my friend Boris Gulko adjourned h is game against grandmaster Taimanov in a compl icated rook end ing. Before the resumption h e asked m e to join in the analysis. In order to figure out precisely some very intricate variations, we had to turn to the theory of the rook endgame with f- and h pawns. The elementary information about these endings, wh ich was g iven above, was not sufficient for us. However, the necessary positions cou ld not even be found i n books on the endgame, so that we had to supp lement 'officia l ' theory with our own analyses. Here is a very important key position that we found (see diagram). White's king is cut off on the back rank. Does th is mean that he is bound to lose? It turns out that the answer is no. After a l l , the black king too is not wel l placed - it is cut off on the h-fi le. 1 'lt>g1 ! h4 2 l:tg8 f3 3 llf8 'lt>g3 (or 3 . . . l:i.g2+ 4 'it>f1 'lt>g3 5 l:tg8+ 'lt>h2 6 l:If8) 4 l:tg8+ 'it>f4 5 l:tf8+ 'lt>e3 6 l:te8+ 'it>d3 7 l:td8+ 'it>e2 8 l:te8+ 'it>d1 9 l:tf8(e3) with a draw.

To prevent the king from being pushed onto the back rank , the wh ite rook must guard the 2nd rank , where it is too passively placed . Black wins easi ly, by advancing h is pawns. Alas, a mistake crept i nto our analysis. By continu ing 49 .Ua5! ( instead of the losing king moves) White exploits the long-range power of h is rook and draws by d riving the opponent's king to a less good position : 49 . . . 'it>g4 50 �a4+!

And now 36 . . . �f4 , 36 . . . ll'lf3 or 36 . . . h5 . The conclud ing position of the variation is very promis ing for B lack. But is it won? Couldn't Wh ite have played more accurately some where earl ier? I t is clear that here everyth ing hangs by a thread : the sl ightest add itional improvement to the defence, and the game wi l l end i n a d raw. Black's play can be improved . One is struck by the fact that he delayed sl ightly - h is kn ight d id not immediately reach the neces sary square f5 . Of course, it is desirable to capture on f5 with the knight . It is th is that expla ins the recommendation by Vadim Zviagintsev: 28 . . . h6 !? (a mysterious move at fi rst sight, wou ldn 't you agree! ) 29 �c1 .l:i.f5. After 30 llxf5 l2Jxf5 3 1 'it>d2 (31 l2Je4 is now pointless - the g5-pawn is defended) 31 . . . ll'lh4 Black must win . However, the exchange on f5 i s not essen tial - 30 lbd 1 ! (but not 30 lbe4 We5) is far more accurate for White . For example: 30 . . . .l:i.xf2 3 1 ll'lxf2 ll'lf5 32 ll'ld3, intending 33 lbc5+ or 33 �d2 ll'lh4 34 ll'le1 . Little is changed by 30 . . . We5 31 �d2 �xf2+ 32 lbxf2 lbf5 33 �d3, s ince if 33 . . . lbh4 there is 34 lbg4+ or 34 g3 fol lowed by lbg4+. We see that the position of the pawn at h6 is far from idea l . 1 70 � Grandmaster Technique And yet Zviagintsev's idea is logical - simply it must be put into effect s l ightly d ifferently. I suggest another mysterious move - inciden ta l ly, the same one that Najer made. 28 . . . b6 ! ! 29 Wc1 llf5! White's position is d ifficult : 30 llxf5 tt'lxf5 or 30 tt'ld 1 llxf2 31 lbxf2 tt'lf5 32 tt'le4 h6, threatening either to attack the g-pawn (33 . . . tt'lh4 or 33 . . . tt'le3), or to penetrate with the king onto the 4th rank . As you see, the s imi larity with the Yande mirov-Najer endgame is not restricted to the fact that in both cases the key to the position was an imperceptible pawn move. Here there was also the identical nature of the material and the pawn structure , and also the highly important role played by the activity of the king in a knight ending - a recurrent theme of Black's play in both examples. However in the Stean-Hort game funda mental ly d ifferent approaches to exploit ing the advantage were possible. Which one do you l ike more? The fi rst is purely techn ical (restriction of the opponent's plan ; unhurried improvement of the position ) , but it does not demand deep calculation and therefore it enables time and energy to be saved . The second approach - the transit ion into the knight ending - is much more concrete and requ i res carefu l checking . The qu iet pawn move on the queenside, preparing the exchange of rooks in the most favourable version , can be found only as a result of delving thoroughly into the secrets of the position . There are two aspects to the process of converting an advantage. On the one hand , it demands accuract and methodical play, and on the other hand - an abi l ity some where to cut short the manoeuvring , and find and ca lculate a concrete way to the goal . I t is not easy to sense which is more correct at a particu lar moment. I n the given example both approaches seem to me to be equal ly good , but th is does not often occur. I I I t can happen that a position looks (and i ndeed is) completely won , and yet a player does not manage to convert it i nto a win . Very often (if of course, th ings do not occur in severe time-trouble) the cause is a loss of concentration and insufficient attention to those few resources wh ich are sti l l avai lable to the opponent or which suddenly occur. A very important ski l l , enabl ing th is type of mistake to be avoided , is prophylactic th ink ing , about which I write in l iteral ly every book of mine . The essence of it is that you need to put yourself in your opponent's place , constantly asking yourself the ques tion : what can he undertake , and what would you do in his place if it were him to move? I n some of the examples g iven below the employment of prophylactic th inking ena bled a player to find the optimal ways of exploiti ng an advantage, which at fi rst sight were far from obvious.

Before bring ing the king back, it is important to place the rook on d2.

I I . IMPROVI N G YOUR TECHN IQUE I w i l l now ta lk about how you can improveyour techn ica l mastery. For this you need to study problems which are common to a l l (or to many) types of endings. Problems, such as the enhanced role of the king in the endgame, zugzwang (and a very important specific instance of it - mutual zugzwang, and correspond ing squares) , the advisabi l ity of this or that exchange, and so on. I t is especia l ly important to sense the spirit of the endgame, to develop the optimal mood for playing it, and to understand the psychologi cal chess laws which apply here. Al l th is is best stud ied by analysing practical endings, played by great masters of the endgame. As an example, let us look at a game by grandmaster Ulf Andersson . Andersson - Franco Buenos Aires 1 979 English Opening 1 tDf3 tDf6 2 c4 g6 3 lDc3 d5 4 cxd5 tDxd5 5 e4 lDxc3 6 dxc3 Andersson l ikes and knows how to play the endgame, and so a l ready in the open ing he happily exchanges the queens . 6 . . .

I n the endgame one should carefu l ly watch for the opponent's ideas and if possible frustrate h is plans. Here Black wanted to equal ise the game completely with 1 2 . . . i.c5. 1 2 . . . lt:Jb6?! An inaccuracy! The only defect of B lack's position is that his bishop is more passive than the opponent's. He should have tried to exchange it, by playing 1 2 . . . h5 !? fol lowed by . . . i.h6.

This unhurried manner of play is typical of Andersson . Just in case he improves the posit ion of h is king and awaits a conven ient moment for the further strengthen ing of h is position . This is the way to convert an advantage in the endgame - by do ing everyth ing possible to restrict the oppo nent's possib i l ities, and then, without hu rry ing , look for new breaches in h is defences. To many the rule 'do not hurry' may seem paradoxical, but in fact it is seen in practi cally all the endings of games by the great masters of the endgame. Look carefully at the endings of Capablanca and Flohr, and you will see with what slowness, sometimes bordering on tedium, they convert an advan tage (Sergey Belavenets) . 26 . . . .1L.d8?!

Black resigned . '>t>d7 A player's endgame technique is based on a mastery of the whole arsenal of ideas he has accumulated - from understanding the spirit of the endgame and its most general laws, to minor techn iques which he encounters when studying his own or other players' games. To i l lustrate this , I wi l l acqua int you with one ending of my own , broken up into elementary components . F irst we wi l l examine four ' i ntermed iate products ' , which , incidenta l ly, are qu ite instructive in themselves . 1 ) It is wel l known that in the endgame the role of logical th inking increases . One must be able to compi le p lans, outl ine a scheme for arranging the pieces, and so on. A classic example is provided by the fol lowing ending . Capablanca - Ragozin Moscow 1 936 This is what Jose Raul Capablanca writes about this position : White 's plan is to prevent the advance of the c-pawn (after which the b-pawn could become weak) and to control the entire board up to the fifth rank. This is achieved by moving the king to e3 and by placing the rook at c3, the knight at d4, and the pawns at b4 and f4. After he has attained such a position, White will be able to advance his queenside pawns. The fol lowing moves are easy to understand - Capablanca consistently carries out h is plan . 33 ttJd4 .l:tb7 34 b4 �d7 35 f4 �e7 36 �f2 .l:ta7 37 .l:tc3 �d6 38 .l:td3 '>t>e7 39 '>t>e3 .l:ta4 40 .l;tc3 'it>d6 41 ti.d3 '>t>e7 42 ti.c3 �d6 The requ i red arrangement of the pieces has been ach ieved . Now Capablanca wants to regroup h is forces, by playing h is knight to c3 (or c5) . 43 ttJe2 g6 44 .l:td3+ 45 �d4? �e6 In winn ing positions even h igh ly experi enced players sometimes involunta ri ly relax and make tactical oversights, risking losing the fru its of their correct strategy. That is the case here : White's last move is a serious inaccuracy (45 f5+ ! gxf5 46 ttJf4+ or 46 . . . 'it>e7 46 ttJc3! was correct) , which cou ld have been exploited by 45 . . . �b5 ! . I n the event of 46 .l:te3+ �d6 Black creates the th reat of 47 . . . c5+ , whi le after 46 ttJc3 �xd3 47 ttJxa4 �f1 he regains h is pawn. 45 . . . 46 .l:te3+ 47 ttJc3 .l:ta6? �d6 How to Study the Endgame .Qj 29 The queenside pawns are now ready to advance.

This is fu l ly in the spirit of an important principle in the conversion of an advantage - the 'princip le of two weaknesses' . After creating a second weakness in the opponent's position , by playing against it and then , in case of necessity, again switching the attack to the first weakness, you convert you r advantage i n the most methodical way. I n the broad sense of the word , a weakness i n the opponent's position can be not only a vulnerable pawn or a badly placed piece, but also our own passed pawn, which he is forced to blockade, or an invasion square , which he has to cover. 53 . . • g5 54 .Ud6+ 55 fxg5 56 .llg6 57 l::i.xg5 58 4Jd4 59 .llg7+ 60 l:tg6+ 61 lLlb5 62 4Jd6+ 63 h4 Black resigned . 'it>b7 hxg5 l:i.f8 f4 :l.c8 �b6 'itb7 .U.f8 'it>b8 2) You will have noticed , of course , that when playing the endgame Capablanca twice repeated moves. Here is what Sergey Belavenets writes about th is : The repetition of moves in the endgame plays an important role. Disregarding the fact that it gains time for thinking, it can be mentioned that, by repeating moves, the active side acquires certain psychological gains. The defender, whose position is inferior, often cannot withstand it, and he creates a further weakening which eases his opponent 's task. In addition, repeating moves enables the position to be clarified to the maximum extent. We know that some upholders of 'pure ' chess will severely criticise us for this advice. But we cannot refrain from advising players: sometimes repeat moves in the endgame. In the struggle every chance has to be exploited, and there is nothing ugly or unethical in repeating moves. 3) Let us examine an example from one of my own games. (see diagram) White has an obvious advantage, but for the moment the invasion points are securely defended . 30 � How to Study the Endgame Dvoretsky - Kikiani Kiev 1 970 35 . . . i.d8 I d id not even beg in to examine 36 tt'lbc5 seriously, s ince I noticed an opportun ity to gain a tempo by a simple triangulation manoeuvre with the bishop. 36 i.a7! .l:!.a8 37 i.e3 Threatening 38 tt'lbc5 . 37 . . . 38 i.b6 i.e7 If now 38 . . . i.d8 the move 39 tt'lbc5 gains in strength - the b7-pawn is not defended . 38 . . . .l:!.ab8 We have reached the position with which we began, but with White to move. 39 g3 The 'do not hurry' principle in action : whi le the opponent is unable to do anyth ing , al l the evensl ightly usefu l moves should be made. Why not, just in case, take away the f4-square from the knight? 39 . . . i.d8 40 i.a7 41 i.e3 .l:!.a8 White is not averse to repeating his ma- noeuvring , the opponent does not know what he should fear i n the fi rst instance .

There wil l no longer be a more convenient moment for the p lanned i nvasion at c5: the black rook is not defending the b7-pawn, and the bishop is stuck at d8 . 42 . . . l:tb8 43 tt'ld7 tt'lxd7 44 .l:!.xd7+ .l:!.e7 45 tt'lc5 'itoe8 46 l:!.xe7+ cJ;;xe7 47 l:Id7+ 'it>e8 48 l:!.xh7 tt'lc7 49 h4 gxh4 50 gxh4 Black resigned . 4) Let us examine another endgame by Capablanca.

After the move in the game Black wi l l no longer have any counterplay. Now, fol lowing the example of the Capa blanca-Ragozin ending , White outl ined a scheme for the deployment of h is pieces. Obviously, the knight must be played to e4 , the king brought up to f3 , the rook placed on a6 and the b ishop on the c1 -h6 diagona l , and , final ly, the pawn advanced to f5 . 30 4Jd2 i.e7 31 4Je4 4Jd7 32 .l:ta6 'i;f7 33 'i;f3 4Jb8 34 l:ta8 35 i.c1 36 .l:!.a6 37 f5 38 gxf5 4Jd7 4Jb6 4Jd5 gxf5 The plan has been successfu l ly carried out. 38 . . . �d7 Here I saw that the triangulation method for gain ing a tempo, found two rounds earl ier i n the game against Kikian i , m ight aga in come in usefu l . The only d ifference is that here the tempo is won not by the bishop, but by the rook. 39 l:Ic6 40 .l:!.h6! 41 l:Ia6 �c7 'it>g7 �f7 I t is now White's turn to move . 42 i.h6 .l:!.c8 42 . . . l:td7 is now bad because of 43 l:Ia8 and 44 �h8, winn ing the h7-pawn . 43 �a? �c7 44 �a6 I f 44 �a8 there is the reply 44 . . . .l:i.c6 , and so the rook returns to a6. I n the event of 44 . . . l:Ic8 White would probably have played 45 i.g5!? , but it did not prove necessary to weigh up this move. 44 . . . 4Jc3? Belavenets was right - Black cou ld not withstand the pressure , and he h imself avoids the repetition of moves. Now White carries out a curious ci rcu lar manoeuvre with h is kn ight , resembl ing that which Capablanca made against Yates . 45 4Jd2 ! 4Jd5 46 ttJc4 �f6 47 4Je5+ was threatened . 47 4Jd6+ �e7 48 4Je4 After making four successive moves, the knight has retu rned to where it began . But B lack's defences are now completely d isor ganised . The threat is 49 4Jxf6 4Jxf6 50 �g5. If 48 . . . �f7. then 49 �d6 is decisive . 48 . . . �h8 49 �e6+ 50 i.g5+ Black resigned . �d8 Thus by reflecting on the games of great players and the recommendations which they g ive in their commentaries, and by considering your own competitive experi ence, you can sharply improve you r techni cal mastery.
