Dear readers, You are holding in your hands book nine of the series "Opening for White According to Anand - l.e4". We continue in it the analysis of the Super Opening, which we know as the Sicilian Defence. In this book, we begin analyzing variations arising after the moves V tlf3 tt:lc6. Meanwhile, it is worth mentioning that in parts 2 and 3 we deal also with systems arising after 2 . . . e6. In answer to 2 ... tt:lc6, just like after the majority of the basic lines, I recommend the most principled answer for White - 3.d4. In fact, recently, mostly because of Black's successes in the Chelyabinsk varia­ tion, many strong players prefer to fight for the advantage with White by playing 3 . .!bS, or 3 .tt:lc3. Still, Black usually equalizes in these side­ lines. Anand however, is not afraid at all of the Chelyabinsk variation, so we will follow his example. The first part of the book is devoted to some rarely played moves for Black after the practically forced line 3 . . . cxd4 4.tt:lxd4. If we take into account the fact that from the point of view of common sense we will analyze the "early Dragon" - 4 . . . g6 in one of our next books together with the "true Dragon" variation - then the only moves for Black, which deserve separate analysis are 4 . . . 1fNb6 and 4 . . . eS. The queen-move is quite insidious: experienced Sicilian players use it often with the idea to avoid the comparison of extensive theoretical knowledge. We sug­ gest against it an aggressive plan for White, including castling long and it is not the most popular indeed; nevertheless, it is the most dangerous weapon for him.

6

The variation 4...eS S.liJbS d6 - is "the younger brother" of the Che­ lyabinsk variation and it has been tested even at the highest level. I see no sensible reasons to call that opening system the Kalashnikov varia­ tion, although that name is gaining in popularity and it is universally accepted. It is very important to know well the theory of it, but still White can rely on obtaining the advantage. In the second part of this book we begin analyzing variations con­ nected with the order of moves: 2.liJf3 liJc6 3.d4 cxd4 4.liJxd4 e6 S.liJc3.

As a rule, the move S...liJf6 is like an invitation to the Chelyabinsk vari­ ation and the game transposes to it after 6.liJdbS d6. That will be the subject however of our next book, while here we analyze some not so popular replies for Black on move six. After them, as a rule, there arise much simpler positions and White maintains his advantage against all of them. The correct approach here for White is not to go for more than the position can really provide. The variation S...a6 needs a special treatment by White. Black is try­ ing to play the Paulsen system, avoiding the aggressive plan for White connected with castling long. The number of the adherents to that move-order has increased lately. Still, Black's task in that line is far from easy. There are plenty of new ideas in the principled variation for White - 6.liJxc6 bxc6 7.id3 and that enables him to be optimistic for the future. Meanwhile, the pawn-structure in that line is quite specific and that introduces plenty of strategical nuances, so it is essential for White not only to be well acquainted with the theory, but also to under­ stand profoundly the arising positions. Finally, in the third part of our book, we deal with the basic tabia of the Paulsen system: 2.liJf3 liJc6 3.d4 cxd4 4.liJxd4 e6 S.liJc3 Vlic7. It is amazing that the peak of interest towards that variation at the begin­ ning of the

2 1st century is due mostly to Anand,

who began to play like

that regularly with Black and he had excellent results. His opponents, belonging to the world elite, started gradually to find the antidote to that system and Vishy decided quite reasonably that there were some other acceptable systems for Black as well. The system is still quite popular though. I recommend to White an aggressive set-up, which as we will see later, has become nowadays an almost universal plan in numerous lines of the Sicilian Defence. It includes ie3, followed by Vlid2, castling long and a kingside attack. All that is too schematic, since

7

Black has numerous plans at his disposal, but White can rely on ob­ taining the advantage thanks to our interesting analyses in many varia­ tions. In particular, I believe that the principally new idea (11.�d4!?) in the main line might become the subject of lively theoretical discussions in the forthcoming years. I hope that the new book would help the White players against the Sicilian Defence to create more problems for their opponents and it would help to clarify why the Super Opening is so popular after all.

I

wish my readers won many beautiful games in the future!

J;ib6 (Chapter 2) and 4 . e5 (Chapters 3-4). They have a com­ mon idea - Black is attacking im­ mediately his opponent's knight on d4. The first two moves are not so popular anymore presently, but the move 4 . . . e5 still can be encountered in super high-level tournaments, including Wijk aan Zee and Linares. We have also analyzed in the first chapter of this book numer­ ous lines for Black on move four, which are only very seldom played nowadays. ..

White preserves some edge in this position, mostly thanks to his better pawn-structure. It might be also essential that his bishop is stronger than Black's knight.

Conclusion Black has many possibilities at his disposal on movefour, but that should not make you change the correct evaluation of his prospects. His moves can be divided in two not so equal categories: 4 ... d5 (vari­ ation c) and all the rest. The correct appraisal of the second group has been made long ago and that is - Black has serious difficulties. In variation a, he falls behind in development considerably, while in variation b, his pawn-structure presents Mite with a clear advan­ tage. Meanwhile, it is essential that Mite's bishop manages to occu­ py the a2-g8 diagonal and his knight on d4 not only does not retreat from the centre, on the contrary - it is redeployed to a more active position. Our negative evaluation of the rest of Black's possibilities, which have been mentioned in short at the beginning of the chapter, should not put you in any doubt about that too. Concerning variation c, Black manages to simplify the position in­ deed, but only at the price ofcompromising his pawn-structure on the queenside. That type ofplaying seems not to be so attractive to the ad­ herents to the Sicilian Defence nowadays. Infact, Mite does not risk anything and the maximum that Black can rely on is a draw, since he has practically no chances of seizing the initiative whatsoever.

l.e4 cS 2. tiJj3 tiJc6 3.d4 cxd4 4. tiJxd4 Yfff b 6 S. tiJ b3 Conclusion We have analyzed the move 4 . . . Vfff b 6 in this chapter - Black repels White's knightfrom the centre with the idea to transpose to some ba­ sic lines of the Scheveningen variation, or the Paulsen system, except that White has won a dubious tempofor the retreat ofhis knight away from the centre. After theforced move S. tiJ b3, Black plays either a) S. . . e6, o r b) S. . . l:lJf6. In variation a), Black does not exert pressure against the centre and therefore White can begin his actions in the centre and on the kingside after 6. tiJc3 Yfff c7 7/4, without being afraid of the move ib4. Later, his plan includes occupation of space on the kingside according to the scheme ofthe Keres Attack - with the help of the pawn-advance g2-g4-gS and he usually castles long. Black's main problem is that he has no safe place for his king. On the kingside White has everything ready for his attack there. In the centre, Black's king impeded the co­ ordination of his pieces, while ifhe castles long he has no counterplay in sight. Meanwhile, White has active possibilities on both sides of the board. In variation b) Black exerts immediate pressure against the cen­ tre and White must play the move 7. Vfff e2!? in order to proceed with his actions in the centre and on the kingside. He prepares castling long and he fortifies his e4-pawn. After the natural moves 7. . . ib4 8.id2 0 - 0 9.a3, Black has two possibilities: b3a) 9 . . . i.xc3 and b3b) 9 . . . ie7. In variation b3a) Black presents his opponent with the two­ bishop advantage, trying to prove that White's pieces on the kingside are misplaced. Black has problems to develop his queenside however and that becomes quite obvious in the main line. White sacrifices the exchange and he destroys the pawn-shelter of Black's king having a very powerful initative. In variation b3b) Black retreats his bishop to the e7-square with the idea to exploit later the move a2-a3 as a target for his queenside attack. After 1 0 . 0 - 0 - 0 , Black's best move seems to be 1 0 . . . dS, entering a position of the type of the French Defence The wonderful idea of GM D.Rogozenko - 13. ie3 Yfff c7 14. Vfff hS!? bS lS. id3 - puts under doubt the entire defensive concept by Black, since White's chances are clearly superior in a middle game with actions on both sides of the board, because of his lead in development and our analysis proves that convincingly.

He weakens the en­ tire complex of dark squares in his camp by giving up his dark­ squared bishop and that involves a definite strategical risk. Still, it is not so simple for White to ex­ ploit that, because he makes sev­ eral moves with one and the same piece and he falls behind in devel­ opment considerably.

of his pieces by exploiting the vul­ nerability of the dark squares on Black's queenside. He must try to create new objects for attack and to break thus his opponent's defence. He activates his bishop, creating the unpleasant threat 2 2 .f4 in the process. Meanwhile, he has the possibility to create an isolated pawn for his opponent at an opportune moment with the move '!e3xd4. It is rather difficult for Black to parry White's threats. His attempt to do that with the move 21.. .f5, can only worsen his situation - after 2 2 .'!d3 Black will be paralyzed to protect his central pawns, while in case of 22 . . .f4, he simply loses a pawn - 23.,ixd4 exd4 24 . .!g6 �e7 25.�e4±

Conclusion The variation 4 . . e5 5. tLl b5 a6 - is not such a frequent guest in the contemporary tournament practice. Still, it remains interesting, be­ cause ofits strategical complexity. Black weakens his pawn-structure at an early stage of the game and in addition he presents his opponent with the two-bishop advantage. His hopes are based on his lead in development in order to manage to either create some counterplay in the middle game, or to repair the defects of his position. That plan has a certain drawback - White can enter an endgame (That decision is usually quite unpleasantfor Black, from the psychological point of view.). The point is that Black's chances of equalizing are connect­ ed with the possibility to push d6-dS, but the game is opened after that, usually infavour of White, because of his powerful bishops. The pawn-structure remains asymmetrical and that is infavour of White too, particularly if he maneuvers skillfully. Black is faced with a dif­ ficult defence. White's advantage is due to long-term strategicalfac­ tors and he only needs to watchfor someforced lines and tricks, while he follows his plan. He must also be careful not to change the pawn­ structure - especially on the kings ide. .

This order of moves became fashionable at the end of the 80ies of the last century and it was quite interesting for the theory of the Sicilian Defence. The position resembles a lot the Chelyabinsk variation. It arises sometimes via a transposition of moves, but meanwhile I would like to point out the important difference: Black delays the development of his king's knight, preventing thus White's move .tgS and he pre­ serves the possibility to continue at some moment with the ma­ neuver .tf8-e7-gS, as well as with the pawn-advance - f7-fS. This system, just like the Chelyabinsk variation, became modern mostly thanks to the profound analyses and the vast experience of GM Evgenij Sveshnikov.

6. tL) lc3 White can make use of the fact that his knight is still not on c3 and he can play 6.c4. This move used to be considered as the best, but subsequently, Black found his way and White began to have problems maintaining his advan­ tage. The main drawback of the move with the c-pawn is that the d4-square is weakened irrevoca­ bly. 6 a6 Black repels his opponent's knight to the edge of the board and that looks quite logical. After 6 . . . tLlf6, there arises the basic position of the Chelyabinsk variation - see 4 . . . tLlf6 (Book 10). Black has also tried 6 ... .te6, but then White plays 7.tLldS. In case of 7 .. J'k8, White follows with 8.c4 a6 (If 8 . . . tLlf6, then 9.tLlxf6+ �xf6 1 0 . .te3 and it is sufficient for Black to play neither 10 . . . �d8 11.y;![d2 a6 12.tLlc3;t Ivanovic Gostisa, Belgrade 1988, nor 10 . . . �g6 11.f3;t and White has a stable advantage thanks to the vulnera­ bility of Black's d6-pawn.) 9 .tL)bc3 (Notice that the knight was not . . •

Now, Black has numerous possibilities. White's knight on dS is very powerful, so Black is usually trying to neutralize it im­ mediately.

Sometimes Black tries the move cl) 8 .ie7, with the idea to avoid the pin along the h4-d8 diagonal, but still he most often chooses the lines : c2) 8 tOge7, or c3) 8 tOce7.

Now, White's initiative is quite real. He controls the d5-outpost and he has a passed pawn. In the game Janetschek - Petschar, Austria 1991, after: 17 . . . lLla5 18.tLlcb4 hC1 19.1MI'xc1 ib7, White could have increased his advan­ tage with the help of the line: 2 0 . Elxa3 Elc8 21.1MI'e3±.

9.c4! That is the only way for White to fight for the advantage. Black is practically forced now to act in a gambit style. 9 . . . lLld4 He sacrifices a pawn, relying on his quick development and his future pawn-majority on the kingside in order to obtain suffi­ cient compensation. We will see however, that after a precise play by White, Black's hopes would be in vain. About 9 . . . tLlxd5 1O.exd5 lLld4 11.cxb5 - see 9 . . . tLld4. The line: 9 . . .

This situation is quite typical for that system. Black has some compensation for the pawn in­ deed, but it is only enough to contain his opponent's initiative a bit. White cannot develop eas­ ily his forces and he has problems starting the realization of his ex­ tra material, but still he has made the first step towards accomplish­ ing that goal. Meanwhile, it is es­ sential that Black's e6-square has been compromised. c3) 8

This is an original line and it has numerous adherents. It owes its popularity to some chess play­ ers from the city of Omsk in Rus­ sia (Vladimir Shcherbakov and Marat Makarov, who played it regularly at the beginning of the 76

80ies of the last century. The idea of the retreat of the queen's knight to e7 for Black is not to lose a tempo after the trade on dS. His other knight will be developed lat­ er to f6 and it will exert pressure from there against White's central pawn. 9.c4 That is the best move for White. He plays sometimes 9.AgS, but in that case, the pin along the h4-d8 diagonal is not so annoying for Black as in the Chelyabinsk variation. 9 tDxd5 It is useless for Black to play: 9 ...

For example, it is slightly prema­ ture for him to play 11 .. .f5, in view of 12 . .td2 . Now, White would counter 12 . . . gb8 with 13 . .ta5 �e7, Alves - Balabaev, corr. 2000, 14.�a4+ ! ? i.d7 15.�a3;l;, while in case of 12 . . . a5, Toth - Kaman, Hungary 1995, it is very strong for White to continue with: 13.�b3 ! ? llJf6 14.�b6;l; - and the exchange of queens is definitely in favour of White in similar situations. Black plays much more often 1l . . . ,te7 (That move is more flex­ ible in comparison to 11 .. .f5.) and White should better react to that with 12 . .td2 . Black has numer­ ous possibilities here, but White maintains his advantage in all the variations: Black loses his castling rights after: 12 . . . .tf5? ! 13.,ta5 �b8 14. llJb6 ga7 15.�a4+ @f8 16.i.e2± Da­ niliuk - Amurskij, Armavir 1995.

Black's other possibilities are not played so often, but still they are interesting and we will deal with them in details: His attempt to attack his op­ ponent's central pawn with 15 . . . if5 - after 16.a5 Eib5 (If 1 6 . . . �d7, as it was played in the game Ko­ tsur - Fedorov, Istanbul 2000, then 17.ttJb6 �b7 1B.Eicl±; it is in­ sufficient for Black to opt for: 16 . . . .ie4 17.ttJb6 Eixb6 1B.hb6 �aB 19.if3± Sherzer - Gostisa, Buda­ pest 1990.) 17.ttJb6 Eixb2 1B . .ixa6 - Now, Black's rook is isolated from the rest of his forces and it comes under attack.

Chapter 4 move - lS . . . Elb4 in the game Mo­ tylev - Shabalov, Bermuda 2 0 03 and there followed: 16 . .id2 'ZlxdS 17.hb4 'Zlxb4oo.

Conclusion The system with the early pawn-advance e7-e5 is often played in the contemporary tournament practice and it is one of the most prin­ cipled in the theory of the Sicilian Defence. Black gives up the central d5-outpost indeed, but he tries to compensate that with rapid mobili­ zation offorces and occupation of space on the queenside. In the main line (7. . . b5), Black has problems lately, therefore the adherents to that variation have started playing more often the other lines (7. . . ie7 and 7. . . i e6), which can be considered as not so well an­ alyzed. As we have seen in this chapter - liVhite obtains the opening advantage with a precise play. The arising positions are rather sharp and quite various strategi­ cally. It is too dangerous to play only common sense moves for both sides, so we advise our readers to study thoroughly the variations in this chapter. We will mention that the pawn-structure, which is typical for this system, can be encountered in some other schemes in the Sicilian De­ fence - that is for example the Chelyabinsk variation and some lines of the Najdorf variation. We will study these variations in our next volumes. 82

Taimanov Variation 5 a6 . . .

Black often uses different or­ ders of moves in the Sicilian De­ fence and that enables him to avoid certain systems, which do not make him too enthusiastic (the reasons for that are usually just subjective). Still, there come moments in which Black must make key decisions and that is the case now. In Chapter 5, we have analyzed predominantly some sidelines af­ ter which White has no problems to maintain his advantage. In Chapter 6, we are dealing with some rare lines, which Black resorts to after 5 . . . tbf6 6.tbdb5;

while to his main line - 6 . . . .tb4 (If we do not count the move 6 . . . d6, which after: 7 . .tf4 e 5 8 . .tg5 leads to the Chelyabink variation - it will be dealt with in the next book of our series) we devote our Chapter 7. That is a reliable varia­ tion, but it has a serious drawback - Black is trying to solve his open­ ing problems in a too simple fash­ ion. He manages to obtain a free game indeed, but instead White has some long-lasting pluses like the two-bishop advantage and a superior pawn-structure. As a rule, it is too difficult for Black to neutralize completely these two factors. The next chapter marks the beginning of the analysis of the Paulsen system - which is one of the most reliable in the Sicilian Defence. It is in particular a basic opening weapon in the "Black" opening repertoire of Vishvana­ tan Anand and Sergey Rublevsky. In Chapters 8 and 9, we analyze 83

the Taimanov variation: S . . . a6 6.tZlxc6 bxc6 7.!d3.

84

That relatively old system of development is presently very fashionable again and Black must consider it after some other orders of moves too (for example in the variation 2 . . . e6 3.d4 cxd4 4.ltJxd4 a6 S.ltJc3 Wic7 6.!d3 ltJc6 7.ltJxc6). Black has a good pawn centre indeed; nevertheless, White has the initiative, because he controls more space.

We will analyze in this chap­ ter all the moves for Black, which have been tested in practice, except the most popular: (5 . . . lDf6, 5 . . . a6 and S . . . �c7): a) 5 . . . d5? ! , b) 5 J.c5? ! , c) 5 �b6? ! , d) 5 .tb4? ! , e) 5 lDxd4? ! , f) 5 d 6 (without the transposition to the Najdorf and the Scheveningen variations). 111e re are some other moves too, which have been played only very seldom: S ... J.e7? - 111i s passive move enables White to obtain a sta­ ble advantage with energetic play. 6.lDdbS! d6? (about 6 . . . a6 7.lDd6+ ixd6 8.�xd6 - see S . . .

Conclusion We have analyzed some not so popular lines in this chapter. In variation a), Black opens the centre, but he remains behind in de­ velopment. White occupies the e-file and he impedes the mobiliza­ tion of his opponent's forces. In variations b), c) and d), Black has great problems in connection with the vulnerability of his pawn on d6. In variation e), Black enhances his opponent's development and then he is forced to create weaknesses in his position. The move 5. . . d 6 has only seldom any separate importance and w e have analyzed it in variation f). The game usually transposes to the Scheveningen variation; otherwise White exploits the delay of the development of Black's knight onf6, or its deployment to the e7-square and he seizes the initiative on the kingside.

In this chapter we will ana­ lyze a) 6 a6? ! - that move forces White to check from the d6-square, which he intended to do anyway and b) 6 . . . �c5 - this move is played with the idea - in answer to the check on d6 to con­ tinue with �e7 and to obtain a lead in development with a pur­ posefully deployed dark-squared bishop. The next chapter will be devoted to the more popular (and obviously better) move - 6 . . . �b4. The most often played move in that position is - 6 . . . d6 - and it is used mainly to eliminate the lines for White, in which he de­ velops his bishop to bS (1.e4 cS 2.ltJf3 lDc6 3.�bS, or 3.ltJc3 lDf6 4.�bS), transposing after 7.!f4 eS (It is too bad for Black to play 7 . . . ltJeS, because White follows with 8.�d4, winning a pawn: 8 . . . a6 9.lDxd6 hd6 lOJ�d1 or 9 ... §'xd6 1O.heS) 8.�gS a6 9.lDa3 bS, to the "starting" thematic position of the Chelyabinsk variation of the Sicilian Defence. It will be ana­ lyzed thoroughly in our Book 10. Black cannot play 6 . . . dS?, be­ cause of the simple tactical opera­ tion: 7.exdS exdS 8.lDxdS lDxdS • • .

Contrary to the Paulsen­ Kan Variation (2 . . . e6 3.d4 cxd4 4.lDxd4 a6) Black has played the active move lDc6, instead of a6, and it is fruitless for White to con­ tinue with his calm development. For example after 6.�e2, Black obtains a very good game by play­ ing simply 6 . . . �b4, attacking his opponent's e4-pawn. White must fight for the advan­ tage by exploiting the temporary weakness of the d6-square and he can do that in two possible ways: 6.lDxc6 bxc6 7.eS lDdS 8.ltJe4, es­ tablishing firm control over the d6-square, but falling behind in development, or by playing the move that I recommend to you 6.lDdb5 With the idea to follow with �f4, threatening checks from the d6 and c7-squares.

Chapter 6 9 . WfxdS - and White wins a pawn, for which Black has no compen­ sation whatsoever. For example after: 9 . . . tLlb4 1O:�c4, White is threatening a double attack on the c7-square. Black reaches a much worse version of the starting position of the Chelyabinsk variation after: 6 . . . b6? 7.,if4 eS 8.,igS±, or 6 . . . ,ie7? 7.,if4 e S (or 7 . . . 0 - 0 B.ic7 WfeB 9.tLld6 ,ixd6 1O.,ixd6 tLle7 ll. tLlbS+-) 8 .igS - and he cannot even repel White's knight from bS, because he has not played the move d6 yet. Black has tried several times the not so purposeful move here - 6 . . . Wfb6 (His queen is attacking nothing from that square and it only comes under attack.) 7.,ie3 WfaS B .,id2 WfdB? 9.if4 eS 1O.igS ib4, Svidler - Karasev, St. Peters­ burg 1999, 11.tLld6+ hd6 (11 . . . mfB 12.,ic4± WfaS 13.0-0 ixc3 14. bxc3 Wfxc3 1S.ixf6 gxf6 16.WfhS+-; 1l ... me7 12.ixf6+ gxf6 13.tLlfS±) 12.Wfxd6± with the threats tLlbS, or tLldS. It is better for Black to opt for: B . . . Wfb6 9 .if4 eS lO.ie3 (It is not so convincing for White to continue with: 1O.igS a6 11.ixf6 axbS 12 .igS ib4 13.id3oo) 10 . . . WfaS 11.f3 and White has the edge, because Black's d6-square is quite vulnerable, while the pawn-sacri­ fice 11...dS is not quite correct, be­ cause of White's simple reaction: 12.exdS tLlb4 13.mf2 its 14.d6±, or 13 . . . a6 14.a3 axbS (14 . . . tLlxc2 1S.Wfxc2 axbS 16.ixbS±) 1s.ixb5± 102

a) 6 a6? ! This is not a good move for Black - he simply forces White to play tLld6 and that leads to the disappearance of the important dark-squared bishop for Black. 7. tLld6+ hd6 8.Wfxd6 ..•

Now, Black must either repel or exchange White's queen on the d6-square. His basic moves are - al) 8 . . . �a5 and a2) 8 . . . �e7. Black has also tried in prac­ tice: B . . . bS - This move seems to be useful (Black must develop his queenside somehow. . . ), but on the other hand he weakens his queen­ side and later White can exploit that with the move a4. 9.a3 (White is threatening b4.) 9 . . :�e7 10.if4 tLlhS 11.�xe7+ tLlxe7 12.id6 tLlf6, Tian - Onufreichuk, Sydney 1996 and here White's simplest line would be: 13.a4 bxa4 14.f3± with the idea to follow with tLlxa4 and then depending on circumstances tLlb6, or tLlcS; It is useless for Black to play B . . . h6, because White does not intend to develop his bishop to gS anyway. 9.it4 �e7 10 .0-0-0

4. 0,xd4 e6 S. 0, c3 0,f6 6. 0, dbS ib4 7.a3 hc3 8. 0,xc3 As for the two-bishop advan­ tage - Black has good chances to exchange one of the bishops (the one on the d3-square) either for a bishop (ic8-f5), or for a knight (0,c6-e5). He will contain the ac­ tion of the other bishop with his pawns somehow (d4, h6). Finally, the weakness of Black's isolated d5-pawn (or d4) is not so great, since knights are much more effective, in the fight against an isolated pawn, than bishops are. Still, the evaluation of the posi­ tion as better for White stands; he must take care of his opponent's ideas and counter them adequate­ ly, for example, he must keep his bishops from being exchanged. The most natural move for Black in that position is - b2) 1 0 0 - 0 , while the only way in which he can hope to exploit ad­ vantageously the fact that neither side has castled is - bl) 1 0 d4.

This is the main line for Black and the entire system with the move 6 ... i.b4 owes its resurrec­ tion to it during the years 2 0 0 12003, when it was tested even at the highest level.

Black provokes the move f2-f3, which weakens the e3-square and later he can exploit that with the ma­ neuver ttJf6-d5-e3.

White has neutralized his opponent's activity in the centre. Black's pieces have been forced to retreat to passive positions and White's stable positional advantage is obvious.

Chapter 7 Conclusion The order of moves, which we have analyzed in the last two chap­ ters - l.e4 c5 2JiJj3 lLl c6 3.d4 cxd4 4. lLlxd4 lLlf6 5. lLl c3 e6 - enables White, contraryfor example to the Paulsen variation, to play 6 . lLl db5, exploiting the weakness of the d6-square. As you have seen in our chapter 6, these lines, in which Black al­ lows his opponent to deploy a piece (a knight and after its exchange the queen and sometimes the bishop) on the d6-square, they all lead to a worse position for Black. That is not surprising, because whenever Black's pawn is on d7, he has great problems to develop his queenside; meanwhile White also has the two-bishop advantage. It is a little better for Black (naturally with the exception of the moves 6 . . . d6 and 6 . . . !J.b4) to play 6 . . . !J.c5, after which it is pointless for White to check on d6. In the main line - 7. !J.f4 0 - 0 8. !J.c7 Wfe7 9. !J.d6 hd6 1 O . Wixd6 lLle8 11. Wfxe7 lLlxe7 12. 0 - 0 - 0 j5 13. lLl d6 lLlxd6 14. '8xd6 fxe4 15. lLlxe4 - Black ends up in a slightly worse endgame with a bad light-squared bishop. The evaluation of the system 6 . . . !J.b4 7.a3 !J.xc3+ 8. lLlxc3 d5 9.exd5 exd5 is more complex. Black presents his opponent with the two-bish­ op advantage and he complies with the isolation of his central pawn. Still, Black has afree development and a powerful counterplay. In the main lines after: 1 0 . . . d4 11. lLl e2 !J.j5, as well as: 1 0 . . . 0 - 0 11. 0 - 0 d4 12. lLl e2 !J.g4, or 12 . . . Wfd5, White can maintain his advantage only by a very precise play. His chances are to either attack Black's d4-pawn (Wfd2, '8adl, often - b4 and !J.b2), or to play on the kingside (!J.g5, lLlg3, doubling rooks along the e-Jile). White should better try to keep both his bishops on the board, since that would provide him with a better endgame. Black had good results at the beginning of the 21st century in the variation - 12 . . . !J.g4 and that on the highest possible level. Presently however, White has found a correct order of moves and that enables him to maintain his advantage.

Conclusion We have started analyzing in this chapter the variation with 5. . . a6, introduced i n the tournament practice during the 6 0 ies of the last century, by the grandmaster from Saint Petersburg M. Taimanov. At first, Black's main idea used to be the piece set-up - 0,ge7, Jollowed by 0,xd4, after which his king's knight was usually perfectly placed on c6 and that was instructively demonstrated by Mark Evgenievich in numerous games. Later, White managed to counter that scheme quite convincingly and Black began to use that order of moves in order to avoid the development of White's pieces according to the following active set-up : ie3, Wd2 and 0 - 0 - 0 . In that case, Black is prepared to meet 6. ie3 with the simple reaction 6 . . . 0,f6 and White cannot play 7. Wd2, because of the active move 7. . . ib4 and then he will be faced with a difficultfight to equalize. White exchanges knights on c6 and he not only prevents thus Taimanov's set-up, but he has a quite effective scheme of development in mind. Naturally, that exchange has some advantages and some drawbacks for White. He acquires a lead in development and he has good prospects of occupying additional space on the kingside and in the centre. Meanwhile, the main drawback of that exchange is that Black obtains an elastic pawn-chain and he can handle it in the centre any way he pleases. Black's queen rook also gains an immediate ac­ cess to the semi-open b-file. In variation a, Black continues with the move 7. . . e5 and he simul­ taneously follows the opening principles and he ignores them. On one hand, he prevents his opponent from occupying space in the centre, but on the other hand he makes a sixth move out of seven with a pawn in the opening and that is naturally harmful to his development. White obtains an advantage without too much of an effort. He completes his development with the moves 0 - 0 and We2 and then as a rule hefol­ lows a plan connected with 0,c3-a4 and the advance ofhis c-pawn. As a result of that, Black's pawn-chain on the queenside is destroyed and White can create additional targets there with the move c4-c5. In case Black counters White's move c4-c5, by advancing c6-c5 himself - then he weakens the important central dS-square. 175

Chapter 8 In variation b), Black's seventh move 7. . . d6, seems to be quiteflex­ ible, but somewhat passive. He is trying to postpone the final decision about his future plans and depending on White's scheme of develop­ ment, Black can continue with e6-e5, or d6-d5. White's pieces set-up is simple then - he castles, he plays .f2-f4 and he places his queen on el. (Black can force, with a precise order of moves, his opponent to play Whl, but that move is favourable for White anyway.) Later, White creates the threat e4-e5 and that compels Black to clarify the situation in the centre. White's pieces are so harmoniously deployed that he has no problems to start active actions irrelevant of the possible pawn­ structure in the centre. It seems more precise for Black to play 7. . :f1c7, which we have analyzed in variation c). He thus prevents White's occupation of the centre and he develops a piece. Meanwhile, just like in variation b, Black preserves the possibility to choose the eventual pawn-structure in the centre. In variation el), he allows his opponent to accomplish the important central break e4-e5, which is connected with a pawn­ sacrifice, but White's pieces become tremendously active after that. Black places his pawn on the e5-square in variation c2), but White then has active prospects on the kingside. In variation c3), White ob­ tains a space advantage on the kingside and in the centre. Instead, Black has the pawn-tandem c5 and d5, but White counters that with the move b2-b3, preventing his opponent from occupying additional space on the queenside. The future of White's knight becomes quite important then. Strangely enough, the ideal squarefor it seems to be dl, since it can be transferredfrom there to f5 (after White pushes f4f5 and he sacrifices his bishop on that square), as well as to the e4, or d3-squares (after White pushes c2-c4). In general, we have to mention that Black's different and rather complicated possibilities in that variation do not help him obtain a satisfactory game and his objectively best line is the move 7... d5, which we deal with in our next chapter.

Chapter 9 14..e�·e2 The placement of the queen on that square is not less active than on g3. The pawn-advance cS-c4 for Black is now impeded. His a6pawn might be hanging at some moment and he lacks space on the kingside and in the centre. 14 0 - 0 The other replies for Black are not any better: 14 . . . i.f8 ! ? - He transfers his bishop to a more ac­ tive position. 1S.c4 ! i.g7? !

White's prospects are better in that position, because he has a space advantage in the centre. Meanwhile, he has good chances of organizing a kingside attack, while on the queenside he can easily cope with Black's possible counterplay.

Conclusion We have analyzed in this chapter the main line of the variation: 5. . . a6 6. lLlxc6 bxc6 7. i.d3 - 7. . . d5. After the natural move 8. 0 - 0 , Black plays most of all the following lines: B . . . i.d6 - variation a). This move is usually a loss of time, because Blackfails to prevent the pawn-advance e4-eS; B . . . '&c7 - variation b). Here,just like in variation a), Black is try­ ing to impede White's control over the e5-square, but he does not suc­ ceed. The correct plan for White, after he places his pawn on eS, was best demonstrated by Anand in his magnificent game against Svidler at the World Blitz Championship. B . . . lLlf6 - variation c). This move seems to be the most logical. Af­ ter 9 . l3 el, Black's main replies are: 9 . . . i.b7 - variation el) and 9 . . . i.e7 - variation c2). In variation cl), after the natural moves 1 0 . i.f4 i.e7, 194

4 . tiJxd4 e6 S. 0.c3 a6 6. 0.xc6 bc 7. id3 dS 8. 0 - 0 White has the pleasant choice between 11. Wif3, Jollowing Anand's ex­ ample and 11.e5 0. d7 12. 0.a4, so in both cases White has a dangerous initiative on the kingside, while Black's counterplay has been impeded considerably. In variation c2, Black tries to complete his development with natural moves, but after: 10 .eS 0.d711. Wig4, he isforced to weak­ en the dark squares on the kingside with 11 . . . g6 (White's task is much easier after Black's other moves.). Here, the move 12. 0. a4, used to be quite unpleasantfor Blackfor a long time, but after the best line for him - 12 . . . Vff aS, it looked like the game should end in a draw after the best defence. Therefore it seems that the move 12.b3 is more logical. It is always usefulfor White in all the variations and then the move 12 . . . Vff aS leads to a diffic ult positionfor Black. In case h e plays something else, White develops hisforces according to the scheme: 0. a4, ih6, he pushes c2-c4 and he has a powerful pressure in the centre and on the kingside, while Black has problems creating any counterplay.

Part 3 Paulsen System 1 . e4 c5 2 . �f3 �c6 3 . d4 cxd4 4 . �xd4 e6 5 . � c3 Y!?1c7

This is no doubt a more flex­ ible line for Black than 5 a6. Now, the popular scheme con­ nected with capturing on c6, fol­ lowed by .td3 (see Chapters B and 9) is not so effective anymore, because Black has played a move, which is much more useful from the point of view of mobilization of forces. There are no objective drawbacks to that move-order. It is too difficult for White to exploit the fact that the b5-square is not controlled by Black yet, since it is considered that in the variation: 6.ltJdb5 YNbB 7 ..te3 a6 B.Ab6 axb5 9.ltJxbS .tb4+ 1O.c3 .ta5 1l.ltJc7+ Vffx c7 12 .hc7 hc7 13.Vffg4 wfB Black obtains a promising posi­ tion. Naturally, if we have in mind that on his next move Black will • • •

most probably follow with a7-a6, White can still try to transpose to the already mentioned scheme with ltJd4xc6. The point is howev­ er, that White has an only move, which is reasonably connected with that idea - 6.f4. In that case, he must at first consider the vari­ ation 6 ... ltJxd4 7.YNxd4 a6, and secondly, even in case of 6 . . . a6 7.ltJxc6, Black has the possibility to change the course of the game with the line 7 . . . Vffx c6. In general, it is worth men­ tioning that the Paulsen system is quite reliable and that is based on the solid pawn-structure d7e6-fl. It is tremendously difficult for White to organize an attack against it; meanwhile the open a3fB diagonal presents Black with additional possibilities. In fact, after the classical move 6 . .te2 , be­ sides the Scheveningen schemes, Black can choose the variation: 6 ... a6 7. 0-0 ltJf6 B ..te3 .tb4 - and presently, there have not been found any clear paths for White to claim an advantage against it. 6 .te3 With that move, White choos.

es another system of develop­ ment, which is becoming univer­ sal in the Sicilian Defence - that is the set-up 'lWd2 , 0-0-0, f3, g4 etc. Here, once again, the move­ order chosen by Black, presents him with additional possibilities and if White wishes to maintain the initiative, he must show right from the first moves of the game flexibility and inventiveness. Chapter 10 is devoted to the move 6 . . . ltJf6 ! ? Black is trying to exploit maximally the advantages of his move-order in that scheme of development. He increases his pressure against the centre, try­ ing to save a tempo for the move a7-a6. In case he manages to ac­ complish comfortably the plan connected with �b4 and d7-dS, then White should simply forget about his dreams of obtaining an advantage in the opening. The de­ fects of Black's set-up can be em­ phasized only with the move 7.f4 ! and h e cannot already enter the standard schemes of the Paulsen system anymore. In Chapter 11, we have dealt with some seldom-played lines for Black after 6 . . . a6 7.Wfd2. Tour­ nament practice has shown that he has no chances of equalizing in that case. It has become evident that Black should better develop his

king's knight first - 7 . . . ltJf6 8. 0-0-0 - and in Chapter 12 we have analyzed different variations with the exception of 8 . . . �b4. White has excellent prospects then too: after 8 . . . bS, he can disrupt the coordination of his opponent's forces with the move 9.if4, while after the move 8 . . . ie7, Black practically loses the advantages that the Paulsen sys­ tem provides for him. There be­ gins a double-edged play on the different sides of the board and White's prospects are superior as a rule. White has more problems to obtain an advantage in the main line. After 8 . . . ib4 9.f3, Black has at his disposal several equally strong lines and we can mention among them 9 . . . ltJe7 and 9 . . . ltJ aS - we have devoted to them Chap­ ter 13, as well as 9 . . . ltJeS 10.ltJb3 bS - which is the most important position of the entire variation. That is the critical line and White can develop his initiative in nu­ merous ways, but Black in his turn can organize various counterplay in many lines. In Chapter 14, we suggest a cardinal solution of that problem - after 11.Wfd4 White is trying to enter an endgame. He does not plan to obtain a great ad­ vantage then, but Black's counter chances are minimal indeed.

Still, after: 7.tLldb5 Wlb8 8.f4 a6 9.e5 axb5 10.exf6 b4 1l.tLlb5 b6oo, there arises a com­ plex and quite unclear position, in which Black has a compact pawn-mass in the centre and his centralized king is relatively safe.

Chapter 1 0 S.Rublevsky, this move creates maximal problems for Black. White's attempt to develop his pieces, following the habitual system, without paying attention to the actions of the opponent, would not provide him even with a minimal advantage after for example: 7:�d2 i.b4 8.f3 ttJxd4 9.'lWxd4 hc3+ 1O.bxc3 O-O! (or 10 . . . eS !?). In the diagrammed position, Black has most often played the obvious move a) 7 d6, and sometimes the more aggressive try b) 7 i.b4. He has also tested in practice: 7 . . . a6? ! - Black remains behind in development after that move and he ends up with an isolated pawn on dS : 8.eS ttJdS 9.ttJxdS exdS, Fransson - Carlsson, Stock­ holm 1994 and here White must complete his development in or­ der to capitalize on the defects of Black's position. 10.i.d3 d6 (It is worse for Black to play: 10 . . . ttJxd4 11.hd4 i.cS 12 .i.xcS 'lWxcS 13.'lWf3± and his queen is out of actions.

Conclusion We have started analyzing in this chapter the Paulsen system, which begins with the move 5. . . Vic7. White answers that with 6. !e3, with the idea to prepare castling long as quickly as possible. He in­ tends to deploy his pieces according to the scheme of the "English At­ tack" in the Sicilian Defence - !e3, Vlfd2, 0 - 0 - 0 , .13. Black plays 6 . . . lLlf6 and h e thus prevents that set-up, but h e exposes himself to other dangerous lines. White's aggressive move - 7/4 puts Black's choice of development to a serious test. In variation a), we have analyzed Black's answer 7. . . d6, which prevents mechanically the pawn-advance e4-e5, but in that case, there arises an unfavourablefor Black line of the Scheveningen varia­ tion. In variation a1), Black tries to organize some counterplay on the queenside by playing 8 . . . a6. Still, in a position with opposite sides cas­ tling, White dominates in the centre and his initiative developsfaster 220

In that case, Black mustfind a series ofprecise moves in order to enter an endgame, in which, despite the simplifications, his defence is not easy at all. In variation a2), Black saves a tempo for the move a7-a6, trying to complete the development of his kingside as quickly as possible. White needs then to waste a tempo for the preparation of his pawn-offensive on the kingside with the move 1 0 . 'iJ.g1, since in answer to 1 0 .g2-g4, the above-mentioned exchange operation in the centre provides Black with a good game. After 1 0 . 'iJ.g1, Black cannot obtain counter chances on the queenside without the move a7-a6 and that leads to unfavourable positionsfor himfrom variation a1). After 10 .. .tiJxd4,Jollowed by l1 . . . eS, White maintains a slight, but stable ad­ vantage in the middle game. In variation b), we deal with the contemporary aggressive linefor Black - 7. . . 1i.b4. He is ready to present his opponent with the two­ bishop advantage, but he might create weak pawns for him on the queenside. In that variation, the idea of GM E.Inarkiev for White to develop his bishop on g2 is quite unpleasant for Black. White's pres­ sure on the long diagonal is very effective, moreover that the defect of the doubled pawns on his queenside is more than compensated by the tremendous effect of the pressure on the semi-open b-file.

Conclusion With the exception of the move - 7. . . ltJf6, which is analyzed in the next chapters, we have dealt in this chapter with all sensible seventh moves for Black. The most logical seems to be - 7. . . bS. He prepares his queenside counterplay, delaying his piece-development. After the natural move B. O - O - O, Black has two main lines: a) B . . . ltJxd4, or b) B. . . b4. In variation a), Blackfalls behind considerably in his develop­ ment and that enables White to organize a powerful attack. It is prac­ tically impossible to memorize all concrete moves in the main line of the variation, but that is hardly necessary. After 2 0 . ltJ dS!! White's attack develops in a quite naturalfashion. In variation b), White has a powerful initiative, thanks to his advantage in the centre. It is worth noticing the maneuver i.e3-a7-d4, with the help of which Whiteforces his opponent's rook to either occupy the not so favourable b7-square, or to go back to aB.

Conclusion We have started analyzing in this chapter the main linefor Black 7. . . lLlf6. After the natural move B. O - O - O, Black replies usually - B . . . ib4. That move is dealt with i n the next chapters. The seldom-played moves enable White to obtain an obvious ad­ vantage in the centre and to develop a powerful initiative most often on the kingside. In variation a), Black plays the standard move B . . . b5 and he starts his queenside counterplay. White's powerful argument - 9. if4 poses serious problems to Black then. Ifhe plays 9 . . . lLl e5 -variation a1), he tries to hold his position in the centre, but White can organize a pow­ erful kingside initiative with precise moves. After 9 . . . �b6 - variation a2), it is not advisable for White to go into an endgame with 10 .e5 �xd4!, since Black would obtain then good counter chances because ofhis powerful pawn-centre. It is much easierfor White to develop his initiative after playing - 1 O . lLl b3. Later, he brings his king to safety on b1 and he attacks on the kingside. In variation b), we have analyzed the strongest linefor Black - B . . . ie7. Its main drawback is that i t is somewhat passive. White's king­ side pawn-assault is obviously faster than Black's counterplay then.

That is Black's most active line. He is trying to prove that White's queen is not well placed on d2 ; meanwhile his bishop sup­ ports the pawn-advance d7-dS, moreover that White's next move seems to be forced. 9.f3 This move is obligatory, but that does not mean that it is bad, since it is a part of White's plan anyway.

White has a powerful centre, his pieces dominate over the entire

board and his king is much closer to the centre and to the queenside, where the actions will develop. 17 lbd7 The further course of the game will indicate - that move is hardly necessary. Black had better play immediately 17 ... i.d7, but that would not have changed the evalu­ ation of the position. White would have proceeded with the same plan as in the game - 18.mb2±. • . •

Conclusion In this chapter, we analyze the move 8 . . . i.b4, which is no doubt the most aggressive for Black. After the forced reply 9.f2-.f3, i.lack has numerous possibilities at his disposal. The main lines arise after 9 . . . lb e5. They will b e dealt with in the next chapters. Some rarely played moves, including a natural reply like 9 . . . 0 - 0, lead Black to rather difficult positions. Meanwhile, White is not sup­ posed to do anything extraordinary. Either he obtains a stable ad258

S.ttJ c3 "Wc7 6. ie3 a6 7. "Wd2 tDf6 8. 0 - 0 - 0 ib4 9.j3 vantage in the endgame, or he develops a powerful initiative on the kingside. The standard pawn-advance for the Sicilian Defence - a) 9 . . . bS turns out to be premature in that situation. White places his knight under three attacks with his move 11 and he disrupts the pawn-shelter ofhis king deliberately on his next move. He gains some time however in order to organize some concrete threats. White thus obtains a con­ siderable advantage with an energetic play in the centre and on the kingside. Black is not well-preparedfor the immediate counter strike in the centre - b) 9 . . . d5. After the natural move 1 0 .a3, he is faced with the unpleasant choice between perishing quickly in the complications and defending a difficult endgame without any counterplay. White had great problems for a long time trying to cope with the move c) 9 . . . tD e7, connected with the preparation of the thematic pawn-advance d7-dS. White's most powerful argument here is the move - 1 0 . tD de2!. In variation cl), we have analyzed Black's most natural move 1 0 . . . dS, with which he practically wins a pawn byforce. Hefalls behind in development though and his pawn-structure on the kingside is destroyed, so that he has problems finding a reliable shel­ ter of his king. In variation c2), Black is trying to organize some coun­ terplay on the queenside with the move 10 . . . bS. White has a powerful maneuver with his bishop then and he forces his opponent to advance his e-pawn, as a result of which Black's d7-pawn becomes very weak for a long time. In variation d), we analyze the line 9 ... tD aS, which was introduced into the tournament practice by Anand. It did not become so popular though, since Black was practically forced to give up his bishop for White's knight on c3. Black's dark squares are weak then and he must trade queens in order not to come under attack on the dark squares. In the endgame then, Black is doomed to a long and laborious defence without chances of obtaining any counterplay.

Conclusion The variation, which we have analyzed in this chapter, is probably one of the key-lines for the evaluation of the entire idea of the aggres­ sive development - �e3, �d2, 0 - 0 - 0 in the Taimanov system of the Sicilian Defence. After 1 0 ... b5, White has a great choice of possibili­ ties. Black's counterplay seems to be sufficient in the main lines, ac­ cording to the contemporary theory. Therefore, I suggest a new move and an original idea, connected with it. 269

Chapter 14 By playing 11. Yff d4, White is trying to exchange queens and that seems to be rather unpleasantfor Black, since he can hardly avoid it. The trade of Black's dark-squared bishop on c3 turns out to be quite favourablefor White. The defect of his pawn-structure is compensat­ ed by his complete dominance over the dark squares, moreover that White usually advances easily c3-c4 in most of the cases and his ad­ vantage becomes overwhelming. If Black refrains from exchanging on c3 then White succeeds in trading queens. The arising positions then are clearly advantageousfor White.
