Part I Chapter 1 1.1.1. Overview The system 3".tiJxe4 (-7) can be success­

This chapter deals with various deviations from the main systems on the third and fourth moves. The gambit 3.�c4 tiJxe4 4.tiJc3 ( 1 2) was Morphy's favourite weapon against the Petroff Defence. Black can switch to the Four Knights Opening after 4".tiJc6 (CSS/ S). The critical move is 4".tiJxc3, although Black must play carefully (position 2). It is interesting that Morphy himself preferred not to accept the gambit and used to return the pawn by S".c6 (-2). The solid continuation 3.tiJc3 allows Black to switch to the Four Knights Opening. This book considers only the move 3 ... �b4, which has its own importance. Black, as it were, is playing the Ruy Lopez a tempo down. Nevertheless, this line looks reliable -

ful only against an unprepared opponent. The Cochrane Gambit is a boon for those players with a penchant for adrenalin (-8II, positions 8-10). For the sacrificed piece White gets two pawns and the initiative. Through the efforts of the Latvian master Vitolinsh this system has become popular. And yet, in my opinion, the gambit is only 90% correct; it hardly makes sense to try it against strong defensive players. Among the various systems of defence, the most promising are S".�e7 (-9) and S".cS (-l O­ II), though future practice might change this assessment. The Paulsen Variation (4.tiJc4) does not seem to be too dangerous for Black (-1214; positions II-IS). On the other hand, the knight's position on c4 (or e3 where it often moves) introduces original motifs into this type of position (position 14). This line can well suit those players who do not like to spend much time studying complex theory, and are looking for a handy system for White instead.

-

enough for Black. At the same time, by continuing 4.tiJxeS White normally obtains the bishop pair, and as modern practice shows, can hope for a small but stable ad­ vantage (positions S & 6). For those play­ ers who want to play this system with White, it is recommended that they see how the ensuing positions are treated by Shirov.

Chapter 2 1.2.1. Overview

There are several ways for White to devi­ ate from the most popul ar continuation

usually manages to solve his opening prob­

S . d4 . Thi s chapter will consider all the de­

prudence and attention. It is not by acci­ dent that Vladimir Kramnik i n a decisive game against the world champion Garry Kasparov, Grand Prix (New York) 1 995,

lems, he needs to play thi s line with great

viations, except S .Wfe2 (see Chapter 3 ) . After S .d3 ctJ f6 6 . d4 B l ac k can transform the game i nto the Exchange Variation of the French Defence (CO l ) by 6 . . . dS . We

chose thi s variation and was very close to winning. The most appropriate way to start

w i l l confine our analys i s i n thi s chapter

studying this system is to analyse game I and positions 1 9- 3 2 . The idea o f the continuation 5 .c4 (-20- 22) i s to i mpede the advance . . . dS . Although the normal developing move S . . . !ibe7 has proved an acceptable choice for B l ack,

only to those lines which are typical of the Petroff Defence. It i s i mportant to note that 6 . . . !ibe7 should be sufficient to equalise (­ I S ) . Thi s flexible continuation yields B l ac k v arious possibilities (-positions 1 6, 1 7 ) . The system S . ctJ c3 (- 1 6- 1 9) leads t o com­ plicated and interesting play. S harp posi­ tions with the kings castled on opposite sides are typical of thi s line. In my opin­

l ately he has often been sticking to 5 . . ctJ c6 .

(-22 ) . This move allows him to avoid the line 6 . d4 due to the great effectiveness of the advance 6 . . . dS (- 1 48 ; see also position 3 7 ) . The continuation 6 . ctJ c 3 leads to vari­ ation 2 1 .

ion, the best idea for B l ac k i s to exchange on c 3 (- 1 8 - 1 9) . Although nowadays B l ack

Chapter 5 1.5.1. Overview this line is treated together with the varia­ tion 9 . . . CLla6 (-48-49 ) . The ensuing pawn structure determines the character of the forthcoming struggle. White usually tries to occupy e5 and to develop an initiative on the queen-side, while B lack seeks his counterchances on the kingside (positions 77-7 8 ) . White has the better chances, but the game is double-edged. The alternative l O . . . ig4 gives the game a different shape (positions 79-8 1 ) . White has not been able to gain an advantage after l 1 .c5 ic7 1 2 .CLle5 ixe5 1 3 .de CLlxc 5 , or in the case of an immediate 1 1 .CLle5 . 9 .CLlc3 is a less popular continuation nowa­ days due to the variation 9 . . . CLlxc3 l O.bc dc (-game 2). Note B lack' s precise defence in the recent game Kamsky - B areev, Linares 1 99 3 (-54). The second part of thi s chapter deals with the ' tabia' of the S taunton S ystem (9.cd cd l O.CLlc3 CLlxc3 l 1 .bc ig4 1 2 .EJ:b 1 ) ( -game 3). B l ack has two main continuations : l2 ... b6 and 12 ... CLld7 . In the first case, as the games Short-Timman, Hilversum (ml4) 1 989 (po­ sitions 8 5 -86) and Oll-Akopian, Manila 01 1 992 have shown, l 4. c4 is not dangerous for B l ack (-57). Instead, variations with the exchange sacrifice 1 4.h3 a6 1 5 .hg ( l 5 .!::l x d5 ! ? - 5 8 ) seem to be more promis­ ing for White. The ensuing positions are very complex and require thorough pre­ liminary preparation. A study of the games S hort - Gelfand, Brussels, cml7 , 1 99 1

This chapter consists of two parts. The first covers White's various possibilities on the mo v e (!::l e I , Wlc2, CLlc3 ) , except for the continuation 9.cd, which is the topic of the

9th

second part. The difficulty in studying the vast amount

of material is intensified by possible trans­ positions of moves. For instance, the mod­ em 'tabia' of the system occurs after both 9.lUc3 ctJxc3 l O.bc ig4 I I .cd cd, and 9 . cd

cd l O.ctJxc3 CLlxc3 l 1 .bc. In such cases we do not treat these lines separately; in par­ ticular, both of the above-mentioned lines are analysed in the second part of this chap­ ter, since the author considers the move order used in the second part to be more precise (thereby W h i te avoids the line 1 0 dc (-52-55 , game 2 ) . The recent practice of this variation does not promise White a big advantage. Thus , after 9 !::l e I , B lack h a s three satisfactory continuations : 9 . . . ig4 (-42, position 7 1 ), ...

Black has a choice between protecting his knight by 9 . . .f5 or sacrificing a pawn after 9 lUa6. According to modem theory, i n the second case B lack gains sufficient com­ pensati on (-46-47 , positions 7 5 - 7 6 ) . If White declines the sacrifice by 9 . a 3 , then 10 .f5 I I . CLlc3 leads to a position which can also occur i n the line w here B lack chooses to protect the pawn (9 . . . f5 l O.CLlc3 ltJa6 I I .a3 ). For the sake of convenience, ...

ation 1 4 . . . ctJ b6 l S .c4 ctJ xc4 requires prac­ tical testing (-64) . The acceptance of the sacrifice l S . . . dc leads to a situation where B lack must pay attention to the various tactical threats of White, who can exploit the active position of his rook on the fifth rank (-positions 92-96). The S taunton System was very popular in the late eighties and early nineties, when it was practised by many leading grand­ master s . It i s sufficient to mention the names of S hort, Timman , Anand, Ivan­ chuk, Kamsky, S alov and B areev.

(-game 3 ) and Ivanchuk - B areev, Linares 1 993 (-positions 87 -89) can help to disclose the subtleties of the variation. Very interesting positions occur after 1 2 . .. ctJ d7 . After 1 3 .h3 ( 1 3 . a4 ! ? -42 3 ) ihS White has tried three continuations. The first of these, 1 4J:%xb7 (-62), leads to a complicated situation in which the white rook is separated from its main forces. The less adventurous 1 4. a4 yields B l ack counterplay on the c-file (position 9 1 , -63 ) . The sharpest move 1 4.E1bS requires espe­ cially careful play by B lack. The continu-

This i s the most dynamic continuation. White immediately attacks the b-pawn and plans to threaten the dS-pawn after I'M. S uch sharp play is fully j ustified by the existing pawn structure. Indeed, if Black completes his development, it will be easier for him to attack the c 3-pawn along the c­ file, than for White to play against Black's maj or weakness - the dS-pawn. The text move also contains a hidden tactical sub· tlety. It seems that it would be convenient for White to include the moves 1 2.h3 �hS. but in this case after 1 3 .gb 1 b6 1 4J1bS B l ac k repl i e s 1 4 . . . a6 I S . g xdS ixh2+ 1 6 . l2l xh2 iWxdS .

In this case White obtains a mobile centre, but Black has no problems in completing his development with 14 . . . ctJ c6 followed by 1'lad8 (-58).

Part II Chapter 1 11. 1 . 1 . Overview

Thi s chapter i s important for Black if he wi shes to play the system 3 . . . ed. He h a s to take into account the fact that after 4.�c4 White can switch to the Urusov Attack in the B i shop ' s Opening (ECO C24/6- 1 1 ) , We offer two recommendations (- 1 5 ) which may allow the successful handling of thi s system without profound theoreti­ cal knowledge . Another deviation - Steinitz ' s move 5 .'tWe2 - is less dangerous for B lack. He can choose between the sharp 5 . . . �b4 ( - 5 ) and the more cautious 5 . . . l2l c5 (-6-7 ) , After 5 .�b5 the best choice for B l ack is to switch to the Ruy Lopez.

Thi s small chapter deal s with 3 . . . d5 and other deviations from the main l ines of the 3 . . . exd4 system, which is analysed in Chap­ ter 2. The continuation 3 . . . d5 is not dangerous for White. He can transpose into the 3 . . . l2l xe4 system (-Chapters 3 -7 ) b y playing 4 . l2l xe5 l2l xe4 5 .�d3 . Other continuations : 4 .�g5 (-2) and 4 . ed (- 1 -2) also give White promi sing play. Those who dislike long theoretical l i nes might prefer Tal ' s move 5 .�b5 (-3-4). However, after this B l ack can switch to the Ruy Lopez (ECO C/65 ( 1 )) by playing 5 . . . l2l c6 ! ? and l ater to the sys­ tem C84 (ECO), which are not considered in thi s book.

Chapter 4 11.4.1. Overview

T h i s and the n e x t c h apter a n a l y s e the 5 . . . ctJ d7 system, which i s currently the most popul ar for B l ack. The first section of chap­ ter 4 (44-5 2 ) summarises White ' s alterna­ tives on move 6. The second section (5563) deal s with B l ack's deviations from the main l i ne (which is covered in Chapter 5 ) . Modern practice has shown that after 6 .Vff e 2 (this main alternative is analysed in l ines 48-5 2 , positions 3 0-3 3 and game 2), B l ack gains sufficient compensation for the pawn . In my opinion, if White is trying for an opening advantage, he has to opt for 6 . ctJ xd7 and follow the main line. There are many i nteresting alternatives for B l ack. The cautious continuation 7 . . . 1e7 gives him a reasonable position (-54-5 5 , positions 3 6-40), although precise play will enable White to keep the initiative.

My attempts to rehabilitate the pawn sacri­ fice in the 7 . . . 1d6 l i ne have not been very successfu l (-56-5 8 , positions 4 1 -42). Al­ though B l ack definitely has active possi­ bilities, I have been unable to obtain full compensation for the pawn (-5 8 ) . Perhaps, it would be helpfu l to analyse the ending Sveshnikov - Zaitsev (-343 ) . Those who prefer gambit play might try the dubious 7 . . . Vff f6 (-59-60, positions 4344) . The recently popul ar line 7 . . . g 6 was put i nto question after the games Anand Huebner (position 48), Rozentalis - I van­ chuk, Debrecen European tch 1 992 (-388) and J . Polgar - Skembri s, Moscow 01. 1 994 (-62 ) . B l ack must search for new defensive methods .

Chapter 6 11.6. 1 . Overview

This chapter and the next are devoted to the 5 . . . �d6 system, or symmetrical v aria­

tion. In chapter 6 the various deviations on moves 6- 1 0 from the tabia of the symmetri­ cal variation are covered . The best choice for White i s t o go for the tabia. However, it requires painstaking work involving the studying of long theoretical lines. If he does not have particularly strong ambitions in the opening stage, he can play for a knight exchange at e4 by ctJ d2 (-76

and 7 8-79, positions 6 1 -66), or ctJc3 (-465 , 80-8 3 , positions 67 -69) . S i nce B lack i s currently experiencing a crisis i n thi s tabia, he may consider choos­ ing the variation 7 . . . ctJc6 ( - 8 5 , position 70). However, my personal experience has been unsuccessfu l : losses in games against Tim­ man (Linares c m ( 8 ) 1 992 -game 4 ) and Ivanchuk (Horgen 1 99 5 ) , along with only one draw, but thi s against Kasparov (Horgen 1 99 5 ) .

The main di lemma when playing sym­ metrical positions is deciding when to de­ viate from the move repetition. The early development of the queen's knight leaves open an additional possibility, in contrast to 6 . . . 0-0 7.c4 ctJ c6, but in my opinion it does not allow Black to achieve equality. 7.ctJxe6 The simplest reaction to 7 .c4 is 7 . . . ctJxd4 8.�xe4 �xe5 9.cd 0-0, since 1 O.�xh7+? xh7 I I :&h5+ g8 1 2 .'&xe5 is bad in view of 1 2 . . . ctJ c2 (-476). 7 . f4 is possible (with change of colours it is analogous to 7 . . .f5 in variation 83 ) . The text move dam­ ages Black's pawn structure. 7...be 8.e4 Other moves are weaker: 8.1:'l:e l �xh2+=; 8.'&e2 a-a ! 9.�xe4 1l{ih4 ! � or 8.ctJd2 ctJxd2 9.�xd2 0-0 1 O.c4 dc= (-477). It i s impor­ tant for White to drive the bi shop back from its active post at d6.

8...0-0 If 8 . . .'&f6, then 9 .�xe4 de 1 0.lLlc3 and it becomes hard for B lack to cope with all his pawn weaknesses. In particular, after 10 . . . 0-0, I l .c5 �e7 1 2.lLlxe4± is unpleas­ ant. The prematurely active 8 . . . �h4 does not promise much because of 9 . g3 �h3 (9 . . . lLlxg3 ? ? 1 0. fg �xg3 1 1 . �e2+ +- ; 9 . . . �f6 1 O.�xe4 ! de I l .lLlc3 �f5 1 2. f3 ! 479.) l O.c5 ! �g4 ( l O . . . �e7 1 1 .�f4± Xc7) 1 1 .�e2 ! �xe2 1 2 . �xe2 �e7 1 3 . f3 lLlf6 14.�f4± -78. It might be interesting to com­ pare thi s variation with (49 8/8 . . . c5/B 2 ) , where the same position with reversed col­ ours occurs and the extra tempo allows White to start an attack. 9.c5! 9.lLlc3 is inconsi stent, since after 9 . . . lLlxc3 IO.bc dc Black maintains his bishop on its ideal post. After the text move the defects of the pawn structure become more eivdent, since the bishop does not have any squares on the b8-h2 diagonal . 9...�e7 10.lLlc3 a

A powerful continuation. White increases his pressure in the centre. The exchange at c3 is unattractive for Black, since he will be deprived of counterplay against the d4pawn. If l O.lLld2, then 1 O . . . �f6 and 1 0 . . .

lLlg5 ! ? are possible ; 1 O.f3 is less precise because of 1 0 . . . lLlg5 I l .lLlc3 E1e8 ! which prevents �e3 and obtai ns a good game . (Kasparov - Yusupov, Horgen 1 995 -529/ 1 0. f3/C ) . 10...f5 The drawback of this move is evident: the important e5 square is weakened. Instead of 1 0 .. .f5 two other continuations deserve attention: 1 0 . . . �f5 1 1 . �c2 �g6 1 2 .lLle2 lLlg5 and 1 O . . . �f6. In this line Ivanchuk demonstrated a strong idea against me in the same tournament: 1 1 .�c2 ! The strength of this move can best be seen in the varia­ tion I l .lLlxe4 de 1 2.�xe4 �a6, when B lack solves his problems. Now after 1 1 . . . �xd4 1 2 .lLlxe4 de 1 3 .�xe4 �a6 White has the unpleasant 1 4.E1d l (-530/ 1 0 . . . �f61D) . 1l.lLle2 After 1 1 .f3 White would have to reckon with 1 1 . . . lLlx c 3 1 2 .bc f4 ! , when B l ack seizes space on the kingside. 1l...�f6 I I . . . a5 ! ?, aiming for the strategically fa­ vourable exchange of light-square bishops, doesn't help much because of 1 2.�a4 �a6 1 3 .lLlf4 �d7 1 4 .�xa6 E1xa6, and White oc­ cupies the key eS-square after 1 5 . lLld3 �f6 1 6.f3 lLlg5 1 7 .�xg5 �xg5 1 8 .lLle5 . 12.�a4!± This is the ideal post for the queen: from here it offers good protection to the d4pawn and simultaneously exerts pressure on Black's weak a7- and c6-pawns. 12...�d7 1 2 . . . �d7 , preserving the possibility of exchanging the light-square bishops by a7-a5 and �a6, deserves consideration. However, during the game 1 2 . . . �d7 1 0 0ked somewhat artificial to me. 13.f3 lLlg5 14.lLlf4

Timman's play in this game is exemplary. Not only does White arrange his forces in the optimal way, but at the same time he effectively controls his opponent's coun­ terplay. White's last move is an i mportant link in his plan (the knight is eventually transferred to e5) and i s also a prophylac­ tic against l 4 . . .COe6, which will be met by l 5 .COxe6 �xe6 l 6 .Ei:e l iWd7 1 7 .�f4 fol­ lowed by �e5 . 14 iWe7 15.�d2 (-532) l 5 .COh5 COe6 l 6.COxf6+ ( 1 6.�e 3 ?

A serious mistake. B lack did not realise what was coming. 1 7 . . . a5 ! was essential. when l 8 .h4 COn 1 9.COe6 is no longer dan­ gerous, since after 1 9 . . . �xe6 20.Ei:xe6i2ld8 the h4-pawn falls. If 1 9.COxd5 ? ! , then 19. .. cd 2o.iWxd7 �xd4+ . White can continue 1 9. h5 ! ? or 1 9 .93, maintaining his advan­ tage, but this line was the lesser evil . 18.�a6! White fixes the weakness at a7, creates the threat of �b7 , and with tempo vacates the square d3 for his knight. 1 8 . . . Ei:ab8 19 .cod3 h4 20 .COeS± f4?

This mistake changes Black's position from difficult to hopeless. 20 . . . h3 2 l .g3 f422.g4 was somewhat better, although in this case he is totally deprived of any counterplay.

Afterword New ideas in the Petroff Defence

The theory of the Petroff Defence is not static and new ideas arise constantly. The Murey System was recently developed fur­ ther (- games 1 -3 ): White looks for defi­ ciencies in Black's original setup along two main l i nes: 5 . d5 (game 2) and 5 . c!tJ xe5 (game 3). Timman became one of the main proponents of thi s system, but even he was not entirely able to solve certain complex defence problems . Black's general crisis in system 3 . d4 (C43 ) deepened o n account o f White's important findings in the quiet line 5 . . . c!tJ d7 6 . c!tJ xd7 ixd7 7 .0-0 ie7 (game 4). However, the author managed to rehabili tate the l i ne 5 . . . c!tJd7 6 . c!tJ xd7 ixd7 7.0-0 id6 (game 5 ) . It should be noted that preci sely thi s line was chosen by Karpov against Kamsky during their World Championship Match in

1 994. Nowadays it is the most promising line in this system. Black's positions seem reliable in the sys­ tem 3 . c!tJ xe5 (C42) . Thus, in the line 8 .c4 a new 'tabia' arises after 8 . . . c!tJ f6 (game 6). Thi s line leads to very interesting positions with manifold possibilities for both sides . Those who prefer the more aggres s i ve 8 . . . c!tJ b4 will have to reckon with a new sys­ tem: 1 1 . c!tJe5 (game 7 ) . Interest in the Petroff Defence is, generally speaking, quite stable. It is worth noting, however, that this old opening has recently won some new adherents: even as con­ vinced a "Sicilian" as Vladimir Kramnik has recently included it in his repertoire !
