PREFACE The first volume has been published not so long ago and I would like to present to the readers the second volume of out three-volume work, devoted to the building of a practical repertoire for White after the move l.d2-d4. In the first volume, we have analysed the openings for White af ter Black's classical response - l.. .d7-d5. In the second volume, we deal with systems for Black connected with fianchettoing of his dark squared bishop. These openings are very complicated and as a rule, there arises after them a complex multi-pieces middle game in which White must know thoroughly numerous typical resources. In this book, we pay most attention to the Gruenfeld Defence (part 1) and to the King's Indian Defence (part 2). In the process of choosing systems against these opening, the author has emphasized on the prin ciple of reliability. Against the Gruenfeld Defence, we analyse the Mod ern Exchange variation with i.e3 and �d2 , in which there often arises a transfer into an endgame, slightly preferable for White. Against the King's Indian Defence, our main opening weapon is the Averbakh sys tem, which has been thoroughly analysed. Black can hardly begin there any active actions on the kingside. It is also worth mentioning that is reply to the move l . . .d6 (parts 3 and 4 of the book), we analyse 2 .e4, therefore this book will be use ful also to the readers who like beginning their games with the move l.e2-e4. In our third and last volume, which will be published at the begin ning of the year 2014, we will analyse thoroughly the Budapest Gambit, the Benko Gambit, the Benoni Defence, the Dutch Defence and some rarely played lines for Black on moves 1 and 2 as well as one of the most popular defences for him against White's move one with his queen's pawn - the Nimzowitsch Defence. The author wishes to express his deepest gratitude to Margarita Schepetkova and Ekaterina Smirnova for their invaluable help in the creation of this book.

Part l The Gruenfeld Defence l.d4 �f6 2.c4 g6 3.�c3 d5
After this move there arises the Gruenfeld Defence. It was in troduced to the tournament prac tice by the Austrian grandmaster E.Gruenfeld back in the year 192 2 . I t was a revolutionary opening at the time. Instead of occupying the centre with his pawns, Black presents it completely to his op ponent. Still, after a while, it turned out that White's task was not simple at all. Yes, he can oc cupy the centre with his pawns without any problem, but then Black's pieces exert powerful pressure against it (ig7, cS, lt:Jc6 and eventually !g4). A single im precision by White may lead not only to the loss of the opening ad vantage, but Black may seize the 8
initiative altogether. The Gruenfeld Defence was in cluded in the repertoire of many world champions. M.M.Botvinnik contributed greatly to the devel opment of its theory and he not only played it in the most impor tant games, including the match es for the world championship, but in 1979 he, together with Y. Estrin, wrote a book devoted to this opening. We must also mention that the Gruenfeld Defence was played by R.Fischer and G.Kaspa rov. The contribution of Kasparov should be particularly empha sized, because he played it for many years and not only in tour nament games, but also in his nu merous match-games against A. Karpov. Presently, during the comput er era in chess, the Gruenfeld De fence has become a part of the opening repertoire of many play ers and this is not surprising at all. The centre is usually opened and the game is almost forced, so all this can be analysed extensive ly and very precisely by comput ers.
Among the contemporary grandmasters we should mention P.Svidler who was champion of Russia many times and used this opening during his entire chess career as well as M.Carlsen. It is also worth noting that in the last world championship match be tween V.Anand and B.Gelfand, the last one chose the Gruenfeld Defence as his main opening weapon against l.d4 and Anand was so unsuccessful in this opening with White that at the end of the match he began to play l.e4. As a main opening weapon for White, we will analyse a line in
which after the exchange on dS, White at first occupies the centre with e2-e4 and then fortifies his d4-pawn with the moves lt:\f3 and ie3 . In the first and second chap ters, we will analyse variations, which are not so popular in the contemporary tournament prac tice. The third chapter will be de voted to the variation with 8 . . 1M/aS, which is considered to be the best for Black by the modern the ory. In this chapter we will see all the responses for him with the ex ception of 9 . . . 0-0. This move will be analysed in Chapter 4. .

l.d4 lL!f6 2.c4 g6 3.lL!c3 d5 4.cxd5
This is the most logical move for White. He exchanges on dS and forces the enemy knight to occupy this square in order to at tack it with the move e2-e4, occu pying the centre with his pawns.

Naturally, it is better for Black to exchange the knight; other wise, he will lose a tempo to re treat is away from the centre. . Still, sometimes h e plays 5 . . . tt:lb6? ! too. The best for White would be to play immediately 6.h3 ! This move prepares tt:lf3 and prevents .ig4. 6 . . . .ig7 7.tt:lf3 0-0 8 . .ie3 c6 (It is not preferable for Black to advance his flank pawns: 8 ... a5 9 ..ie2 a4 10.0-0 a3 ll.bxa3 10

After the trade of the dark squared bishops, he will have chances of attacking on the king side. The potential weakness of the a2-pawn cannot be sufficient compensation for Black.) 9 . .ie2 .ie6. Black is preparing the ex change of the light-squared bish ops. 10.0-0 .ic4 ll.E:cl tt:l8d7 12.a4 aS 13.b3 he2 14.\Wxe2 e6 15.E:fd1 E:c8 16.-igS 1We8 17.e5± and in the game A.Petrosian Taimanov, Tallinn 1980, White obtained a great advantage. Black is practically helpless against the manoeuvre tt:lc3-e4-d6. These two examples are quite sufficient to understand the main defect of the move 5 . . . tt:lb6, since after it Black is incapable of exerting pressure against his opponent's pawns on d4 and e4. White completes ef fortlessly his development and maintains an advantage in the middle game thanks to his power ful pawn-centre.

It remained in the shadow of the plan with .ic4, ltJe2, be cause it was considered that it was not good for White to allow the pin of his knight after .ig4. Later however, it became clear that the pin was not so dangerous for White after all and the move 7. ltJf3 began to be played more and more often in tournaments and became popular.
7 ... 0-0?! This natural move is definitely imprecise, because it enables White to obtain an advantage ef fortlessly.
must exert pressure against White's pawn on d4 as quickly as possible. 8 . .ib5 + . This resource is well familiar from some other openings. White forces the move c7-c6, so that Black's bishop on b7 does not exert pressure against the e4-pawn. 8 . . . c6 9 . .ic4 0-0 10.0-0 .ia6 ll.ha6 ltJxa6 12 .'1Wa4 '1Wc8 13 . .ig5 ;1;. White has a slight edge thanks to his pawn-domi nance in the centre. In addition, Black's pieces are a bit cramped. He obviously lacks space. Later, in the game Kasparov - Pribyl, Skara 1980, White obtained a very promising position with a pawn-sacrifice. 13 . . . '1Wb7 14J''!:fe1 e6 15.E:ab1 cS 16.d5 ! hc3 17. l"i:e d1 exd5 18.exd5 ig7 19.d6 !� Despite the missing pawn, White had very powerful initiative. G.Kasparov demonstrated in this game one of the main ideas in this variation. White should ignore the possible material sacrifices and advance his d-pawn as quickly as possible in order to squeeze the enemy pieces.
8 . .ie 2 !
The strongest move for Black - 7... c5! will be analysed in Chap ters 2-4. It is also worth mentioning the possibility 7 . . . b6? ! White should not be afraid of it, because it is not in the spirit of the main idea of the Gruenfeld Defence. Black 11
Chapter 1 This is the point. White ex ploits Black's imprecision and completes immediately the devel opment of his kingside. Later, the readers will see that in response to 7 . . . c5, we will ana lyse 8.�e3. Now, after 7 . . . 0-0, White does not need this move at the moment.
As a rule, there do not arise original positions following 8 . . . b6 9.0-0 ib7 (9 . . . liJc6 10.ie3 - see 8 . . . liJc6; 9 . . . c5 lO .i.gS - see varia tion B) 10.Wfd3
8 . . . c5 Black's main idea is to create pressure against his opponent's centre. He plays only seldom 8 .. .lt:lc6 9.0-0 b6 (following 9 . . . e5 10.d5 liJe7 ll.ia3±, White has more space and his bishop exerts pow erful pressure on the a3-f8 diago nal, Leon Oquendo - Calzadilla de Ia Cruz, Camaguey 2010) 10. �e3 eS. Undermining the centre with the e-pawn is not so effective for Black as the same with the c pawn. ll.:Bc1 Wfe7 12.Wfa4 �b7 13.:Bfd1 h6 (He cannot win a pawn, because after 13 . . . exd4 14. cxd4 Wfxe4?, White has the re source 15. liJg5 Wfe7 16.:Bxc6± and in the middle game his two minor pieces are stronger than Black's rook and pawn.) 14.d5 liJd8 15. Wfb4 Wff6 16.a4 �c8, J. Graf - Marinkovic, Germany 1991, 17.c4t - There has arisen a position of the King's Indian type and it is more favourable for White, since he has a clear-cut plan for queenside actions: a4-a5 or c4-c5. 12
About 10 . . . c5 ll.i.gS - see var iation B. 10 . . .Wfd7 1l.�g5 liJc6 12.Wfe3 see 10 . . . liJc6. Following 10 ... liJd7 ll.i.gS :Be8, Bravo - Le Quang, Istanbul 2012, White can maintain a slight edge after the typical pawn-ad vance for similar positions - 12. eS! ?t. Now, Black's bishop on g7 and his knight on d7 are severely restricted in their movements. It is worth mentioning this resource works only when Black's knight has been developed to d7; other wise, with a knight on b8, Black will play liJc6-a5 and the weaken ing of the light squares may be unpleasant for White. 10 . . . liJc6 ll.igS Wfd7 12 .Wfe3 :Bfe8, Kreiman - Ehlvest, New York 2003. Here, White obtains a slight but stable advantage after 13.:Bad1 liJa5 14.h4t - he is domi nant in the centre and can devel op his initiative on the kingside with i.h6 and hS.
2.c4 g6 3. lt:J c3 dS 4.cd lt:JxdS 5.e4 lt:Jxc3 6.bc i.g7 7. lt:Jj3 0 - 0 8. i.e2 \WaS 14.4Je5±, Black has won a pawn indeed, but his position is very difficult because his bishop is misplaced on b4 and he lags in development.) 12 .\Wc2 b6 13.gac1 4Jf6, Timman - Roos, Amsterdam 1978, 14.h3 ! ?;!; White has the ad vantage thanks to his dominance in the centre.

9 b6. .••
About 9 ... 4Jc6 10.i.e3, or 9 . . . .ig4 10 . .ie3 - see Chapter 2 , vari ation B. 9 . . . \WaS. This move seems much stronger before White has castled. Here, he can simply con tinue with lO.i.gS ! ? , for example: 10 . . . cxd4 ll.cxd4 i.g4, Sorm Nepomniachtchi, Biel 2007 and now, he can simply capture a pawn: 12 .he7!? ges 13.i.h4 gxe4 14.\Wb1 ges 15.\Wxb7 4Jd7 16.\Wbs;�; - The activity of Black's pieces does not compensate adequately his material deficit.
•••
cxd4
This move leads to a difficult position for Black. He continues with the standard plan for the Gruenfeld Defence - pressure against the d4-pawn. Here, it does not work well however. The point is that after White has castled kingside, he can sacrifice the ex change on a1 in many variations with the move d4-d5 and regains it easily, while Black's knight on c6 will be forced to occupy a very bad position at the edge of the board.
10.cxd4 lbc6 About 10 . . .ig4 ll.i.e3 4Jc6 12 .d5 - see 10 . . . 4Jc6 10 . . . b6 ll.igS .ib7 12 .\Wd3 see variation B.

The move 12 ... ixa1, as a rule, transposes to variation Al, since later Black captures hf3 anyway. Otherwise, if White's knight re mains on the board, Black may have great difficulties, for exam ple: 13.\l;lfxa1 tt:laS 14 . .ih6 f6 15. M8 \l;lfxf8 16.tt:ld4 ! ? This is the point. White's knight will go to the weakened e6-square, very close to the enemy monarch. 16 . . . !xe2 17.tt:lxe2 l:!c8, D e Boer - Den Boer, Dieren 1989, 18.tt:ld4!±, fol lowed by tt:le6 and White's attack ing tandem {queen and knight) seems very threatening.

After this, Black will have great difficulties, because his knight is terribly misplaced on aS. It is not preferable for him to opt for 13 . . . tt:le5. The point is that Black will fail to preserve his knight in the centre. 14 . .ie2 l:!c8 (It would be too risky for him to choose 14 .. .f5 - White has the two-bishop advantage and open ing of the position would be in his favour. 15.f4 tt:lg4 16.!xg4 ixa1 17.exf5 !

Xu Jun - Razmyslov, Seville 2003.) 15. \l;lfa4 b6 16.l:!acl± White maintains an overwhelming advantage, since he has an excellent centre and two bishops, while Black's knight will be ousted from the centre at any moment with the move f2-f4, Malaniuk - Bednar ska, Poznan 2012.

Once again White does not capture on f8, considering quite deservedly that his bishop on h6 is not weaker than Black's rook in this position.

It is also good for White to play 16 . .ig4 ! ?±, taking control over the c8-square and maintaining a great advantage, since he not only dominates in the centre and has two powerful bishops, but Black's knight on aS is terribly misplaced.
In this position, which is very difficult for Black, he made a mis take in the game Yermolinsky Kreiman, Philadelphia 1996 16 e6? and this enabled White to sacrifice exquisitely a pawn with 17.e5 ! and to obtain a decisive advantage following 17 '?;l/xe5 •••

Chapter 1 material is equal indeed, but Black's position is hopeless, be cause White's powerful bishops control the entire board, while Black's pawns on a7 and b6 are very weak and his king and the knight on aS do not take part in the fight at all (White's rook on c1 deprives Black's knight of the c4square).

Meanwhile, it is also possible for him to play 1S.!'i:acl ! ?;!;, or even 1S.!'i:ab1 ! ?;!; and he preserves an edge in both cases.

This move is no doubt more reliable, since Black succeeds in trading advantageously the knights. White still preserves a slight edge thanks to his domi nance in the centre, but must work very hard in order to obtain a real advantage, since there are just a few pieces left on the board as a result of the numerous ex changes.

Conclusion We have just analysed the variation with 7 . . . 0-0 in the Gruenfeld Defence. As a rule, White obtains an advantage effortlessly. It looks like the most dangerous plan for Black is to play b7-b6 and to develop his bishop on b7. White counters this with �d3, i.gS, gad1, combining active actions in the centre and on the queenside.

This is one of the most popular moves for White in this position. He fortifies the key d4-pawn for the Gruenfeld Defence and pre pares to evacuate his rook away from the al-h8 diagonal. This move became popular after Kar pov's game against Kasparov in their match for the world champi onship in the year 1990, as well as after Kramnik's win against Kasparov in their match for the world championship in London in the year 2000 ro.zzy . V.Kramnik plays this variation quite success fully until today. We have to mention that the 20

With this move White pre vents his opponent's pawn-ad vance e7-e6. Still, this bishop move has the drawback that Black 22
gains time to organise counter play on the queenside by attack ing the enemy bishop with his pawns. It may be interesting for White to try 13.f4 ! ? , forcing his oppo nent to clarify the situation with his bishop. After every possible retreat of the bishop, White main tains a slight edge.

Chapter 3 the vulnerable enemy pawn on c3. Still, following 10.id3 0-0 11. 0-0 tt:lb6 12.E:ab1 tt:la4 13.E:fcU, White would have preserved better prospects. He has protect ed reliably the weakness on c3 and now, the deployment of Black's knight on a4 is not advan tageous at all, because it is placed at the edge of the board after all, Rivas Pastor - Korchnoi, Linares 1985.

After this move there arises immediately on the board a quite typical endgame for this opening variation. As in the majority of the endgames of the similar type, White has a slight edge, because thanks to his pawn-centre his pieces can occupy more active po sitions than Black's pieces. In ad dition, White's rooks can exert rather unpleasant pressure on the c-file. In this variation Black must be constantly on the alert about the possible penetration of White's rook to the c7-square. Black has his pluses as well. At first, he has no pawn-weaknesses.
This is an important move. White takes under control the b4square, so that after Black's knight comes to c6 and White's pawn on dS ousts it from there, Black's knight is deprived of the b4square.

Conclusion We have just analysed variations of the Gruenfeld Defence in which Black develops his queen to aS. In these lines, as a rule, there arises a slightly better endgame for White, because his pieces occupy more ac tive positions thanks to his wonderful pawn-centre. Black will need to work hard to neutralise his opponent's pressure on the c-file and to prevent the penetration to the c7-square. If he tries to undermine his opponent's centre with the move f7-f5, then White has the unpleasant plan with the move e4-e5, after which Black's bishop on g7 becomes severely restricted in its movements and White seizes completely the initiative on the queenside. With a black bishop remaining on g7, White will have an extra piece in his queenside actions.

kingside activity has brought some results. There has appeared a weak pawn on g6 in Black's camp. His position is difficult. Kasparov exploited some impre cise moves by White and man aged to save the draw, but this variation became a very rare guest in the contemporary tournament practice and quite deservedly so.

The tactical complications, started with the queen-sacrifice, have ended up in an endgame with an extra pawn for White. De spite the possible technical diffi culties, he has all the chances of realising it.
Conclusion We have just completed the analysis of the variation with 9 . . . 0-0. As a rule, if Black refrains from 10 . . .'i!.d8, he is forced to defend pas sively the slightly worst endgame arising after cxd4 and the trade of the queens. The character of the fight is entirely different following 10 ... 'i!.d8. In this line there arise very sharp positions in which if White wishes to fight for the opening advantage - he must enter a position with a queen-sacrifice. He has only a rook and a bishop for the queen in this endgame, but his powerful pawn on e6 provides him with good chances of maintaining an advantage after a correct play. Naturally, he must have studied thoroughly the theoretical material, because to find the right way over the board in all the intricacies of the numerous possible variations is tremendously difficult.

Part 2 The King's Indian Defence l.d4 �f6 2.c4 g6 3.�c3 i.g7
After this move, there arises on the board the King's Indian Defence (Naturally, with the ex ception of the cases when White does not play e2-e4 and Black ad vances d7-d5. Then, there arise variations from the Gruenfeld De fence, which we have already ana lysed.). Now, contrary to the Gruen feld Defence, Black does not mind White building up his centre the way he pleases. He is trying to de velop quickly his kingside pieces and to attack his enemy castling position with his pawns (f7-f5-f4, g6-g5, h7-h5 and g5-g4). This plan has ended up with numerous crushing attacks for Black. We have to mention that at the dawn 74
of the development of this open ing, the chess world was very sceptical towards it, since it was rather unusual for these times. The critical moment, after which the King's Indian Defence began to be considered as a quite correct opening, was the Candidates tour nament in the year 1953, about which D.Bronstein wrote his re markable book. We must also mention that I.Boleslavsky and E. Geller contributed greatly to the development of the theory of this opening and it was because of them that the King's Indian Defence be came very fashionable. It was quite deservedly that M.Botvinnik said once "We did not understand, the way we needed, the King's Indian set-ups before E.Geller". Years later, the World Cham pions number eleven and thirteen - R.Fischer and G.Kasparov con tributed greatly to the develop ment of this opening. Nowadays, it is played sometimes by H .Na kamura, T.Radjabov and A.Gri schuk, but it has lost its populari ty at the top level. The point is that Black has no real chances of
equ alising in it and White can ob tain an advantage in several ways. It is however another story in the tournaments of one level below the Swiss system events. What is very specific in these tournaments is that the players who are striv ing to occupy a top place in the fi nal standings must play for a win irrelevant of the colour of the piec es. You can encounter the King's Indian Defence there quite often. We will analyse as our main weapon against this defence the Averbakh system - 4.e4 d6 5 . .ie2 0-0 6.ig5, in which White's ad vantage may not be so great, as for example in the Classical sys tem, but he is relatively safe from being checkmated in the middle game. We will devote to this open ing seven of our chapters - from 5 to 11.
In the fifth and the sixth chap ter, we will deal with some seldom played lines for Black in which he avoids the natural move for this opening d7-d6 (Chapter 5) and later schemes in which he plays d7-d6 indeed, but postpones cas tling (Chapter 6). Our chapter seven will be de voted to some not so principled responses for Black among which the most dangerous for White is the move - 6 . . . c6. Black's plans, connected with 6 . . . tt:ibd7, will be dealt with in chapter eight. In chapter nine, we will ana lyse the most popular move in the contemporary tournament prac tice - 6 . . . tt:ia6, while the moves 6 . . . h6 and 6 . . . c5 will be analysed in chapters ten and eleven ac cordingly.

Black has some other possibil ities besides this move. It seems principled for him to try 8 . . . c5, despite the loss of a tempo.

Conclusion We have just analysed Black's seldom played moves in the King's Indian Defence, with which he avoids playing the natural move 4 . . . d6. White must obtain an advantage effortlessly, by advancing e4-e5 at the right moment, but he needs to play accurately. He should not forget the game Letelier - Fischer, Leipzig 1960 and must have in mind that after imprecise moves his beautiful centre may turn quickly into ruins.

One of the peculiarities of the Averbakh system is that White is not in a hurry to develop his king's knight. It is possible that from the point of view of absolute strength of the move, White should prefer 5.lLJf3, followed by 5 . . . 0-0 6.i.e2 eS 7.0-0 and there arises on the board the basic position of the Classical system. Still, from the point of view of the practical chess player, the Classical system is hardly the best choice, since the adherents to the King's Indian Defence for Black enjoy the pos sibility to be able to attack the en emy king. He has many possibili80
ties to do this in the Classical sys tem. I can provide you with nu merous examples in which the players with White have failed to parry Black's attacks and have lost their games.

Conclusion We have just analysed some seldom played moves for Black in the King's Indian Defence. As a rule, White obtains easily an advantage after them and this is not surprising, because even the beginners know how dangerous it is to ignore castling. In the majority of the variations, analysed in this chapter, Black can castle in a period of a few moves, after which there will arise transposition to situations analysed by us in Chapters from 7 to 11. If he does not do that he will be faced with a dif ficult defence.

Black's counterplay, connected with the exchange on c4 and the temporary piece-sacrifice on e4, fol lowed by d6-d5, cannot equalise for him, since it leads to the appear ance of a weak pawn on c6 in his camp. 93

Conclusion We have just analysed the variation with 6 . . . ttJbd7. White obtains effortlessly an advantage in the opening exploiting the basic drawback of Black's sixth move. His knight on d7 does not exert any pressure against White's centre. This leads to the fact that Black will have to exchange on d4 sooner or later and there will arise a position with a long lasting positional advantage for White. He will dominate in the centre and will have the possibility to exert pressure against Black's weak d6-pawn. We will have to mention that a similar type of position arises in the variation of the King's Indian Defence in which White fi anchettoes his bishop on g2 and Black plays tiJbd7. There, as a rule, he is doomed to a passive defence after White parries all his opponent's tactical tricks.

This move is more flexible than the one we have analysed in our previous chapter - 6 . . . lt:lbd7. Black prepares the typical pawn advance e7-e5 for the King's Indi an Defence and also the knight on a6 will not stand in the way of the development of his bishop on c8. If White, in answer to e7-e5, re plies with d4-d5, then Black's knight on a6 will have the possi bility to go to the cS-outpost, ex erting pressure against the e4pawn. Following 6 . . . lt:la6, as a rule, there arise very complicated posi tions with plenty of tactical possi bilities, so it is not surprising that it was tested by such masters of 104
With this move White wishes to emphasize the drawbacks of Black's sixth move. Now, there arise positions similar to the Four Pawns Attack, except that Black's knight is on a6 and White's bish op is on gS. I believe this inclusion is in favour of White, since he had made a developing move, while the placement of Black's knight on a6 may turn out to be disad vantageous. The move 7.f4 be came popular after V.Potkin's win against A.Grischuk in the year 2011. After 7.V9d2, naturally Black advances 7 . . . e5 and as a rule, there arise positions, which are more typical for the Saemisch sys tem.

It seems rather dubious for him to opt for 7 . . . c5? ! . Following 8.d5, there arise positions in which Black's knight is better placed on d7 in order to prevent White's possible central pawn break e4-e5. It is understandable that from the a6-square it can go only to c7, from where it cannot control at all the eS-square. The pawn-advance b7-b5, which the knight on c7 can support, is abso lutely harmless for White, be cause he can parry it with the move a2-a4, or eventually with a4-a5. 8 . . . Wa5 (After 8 . . .

Conclusion We have just completed our analysis of the variation with 6 . . . lLla6. It is quite deservedly one of the most popular responses for Black in the Averbakh system in the contemporary tournament practice. He is try ing to obtain a sharp and complicated position and is ready to sacrifice pawns in his fight for the initiative. Still, after a precise play, White has chances of obtaining an advantage after the opening. As a rule, in this variation he acquires some long term pluses - a space advantage and a powerful pawn-centre. His main task is to overcome the temporary lag in development. After he completes it successfully, Black will be forced to begin defending.

Before that however, we will deal with some not so popular lines.
This move is one of the most popular responses for Black against the Averbakh system, chosen by White. Black ousts im mediately his opponent's bishop from its active position. Still, this move has a serious drawback Black's pawn on h6 is not suffi ciently protected. In the majority of the variations White can win a tempo by attacking it with the move 1Wd2 .

Black is incapable of counter ing White's actions on the c-file and his kingside counterplay is obviously too slow. It seems rather dubious for Black to try here 7 . . . b6. In g�ner al, in the King's Indian Defence, Black fianchettoes his light squared bishop only very seldom, 113

This is the beginning of a standard plan for similar posi tions. White advances his pawn to the hS-square, forcing his oppo nent to play g6-gS and after that Black will have no counterplay whatsoever and will remain in the role of a spectator to the rest of the game. White will prepare pa tiently a breakthrough on the queenside.

This move was popular at the beginning of the 90ies of the past century mostly thanks to the ef forts of grandmasters Z.Lanka. A.Shirov and V.Bologan. Black's main idea is to prepare the pawn advance c7-c5 and to sacrifice a pawn with the move b7-b5, after which there arise positions which resemble the Benko Gambit. Nowadays, this move is played only seldom, because White has found rather convincing ways of neutralising his opponent's initia tive. He can obtain in this varia tion a slight but stable advantage.

This move is chosen by many adherents to the King's Indian Defence for whom it is inconceiv able without the pawn-advance e7-e5. After White's bishop has abandoned the h4-d8 diagonal, Black should not be afraid of los ing a pawn, due to the pin of his knight. The move was the favour ite of S.Gligoric and Y.Balashov. In the variations, which we will analyse, you will see games by such outstanding King's Indian experts like G.Kasparov, B.Gel119

The point is that it is very difficult for Black to organise active ac tions on the kingside (as a rule be cause of the White's already men tioned prophylactic move h4-h5 and eventually g2-g4), while his opponent's hands are free for ac tions on the opposite side of the board.

is very popular in the contempo rary tournament practice. It has been used by V.Ivanchuk, E.Inar kiev, A.Khalifman, V. Bologan and some other strong grandmasters. The last one, by the way, analysed it extensively in his book devoted to the King's Indian Defence. If we rely on the database, the move was played for the first time by young R.Fischer in his game against Y.Averbakh back in the year 1958. Now, contrary to the move 6 . . . c5, which will b e dealt with i n our next chapter, it is not so good for White to close the centre with the move 8.d5, because his bishop on e3 is not so active as on the f4square, where it usually retreats to in the variation 6 . . . c5 7.d5 h6. When Black undermines his op ponent's centre with e7-e6, White's bishop does not exert pressure against the d6-pawn. Therefore, we have chosen as the main line for White against Black's move seven -

White can hardly obtain an edge following 8.d5 e6 9.ti'd2 exd5 10.exd5 mh7 11.h3 :ge8. Now, you can see another drawback of the placement of his bishop on e3 : it does not pin the enemy knight on f6.

In the arising position, Black's prospects are not inferior at all, since he has two powerful bishops, while White can hardly exploit the vulnerability of Black's d6-pawn, or to attack his oppo nent's too active rook on c4. Black's game is much easier in this position. There arise interesting com plications after the move 8.e5. There is plenty of theory amassed in this variation and the game en ters practically by force an end game, in which White has an ex tra pawn.

plest solution for White would be the move 29.lt!d5± and the hor rible misplacement of Black's rook on the aS-square makes his position very difficult. We have seen in this game that Black's counterplay, begun with the move 14 . . . g5, has not led to anything good for him.
Conclusion We have just completed our analysis of the variation with 6 . . . h6 7. il.e3. Black has three main possibilities and after each one of them · there arise very original positions. Still, White maintains an advantage in all the variations. 133
Chapter 1 0 After the plan of Z.Lanka and A.Shirov - 7. . . lL!bd7, 8 . . . c5, followed by the pawn-sacrifice b7-b5, White should better not go after material gains, but following cxbS a6, he should give back the extra pawn with the move b5-b6. After this, Black can hardly create any dangerous ini tiative on the queenside and White will maintain a slight but stable edge thanks to his space advantage. Following 7 . . . e5 8.d5, White's main idea is to advance h2-h4. After that, if Black plays h6-h5, then White transfers his knight to gS and begins active actions on the queenside. If Black does not react to the move h2-h4, then White plays h4-h5 himself, forcing g6-g5 and then neutralises completely Black's counterplay on the kingside with the moves g2-g4 and f2-f3. There arises a very unpleasant situation for Black in which he has no counterplay at all. White can exploit his space advantage and regroup his forces, beginning an offensive on the queen side: a3, b4 and eventually id3-c2-a4, forcing the favourable exchange of the light-squared bishops. Black is faced with a long and passive de fence. After 7 . . . c5, there arise, as a rule, positions in the spirit of the Ma roczy system of the Sicilian Defence. White's game is quite free and he has all the chances of obtaining an advantage in the middle game. The only thing he needs is to watch carefully and to play accurately, during the transition from the opening into the middle game, in order to neu tralise the activity of Black's pieces.

7.d5 This is one of the oldest moves for Black and it was played even during the first half of the 20th century. What can be more logical than this move? If Black cannot play e7-e5, then it looks like he should inflict a strike against White's centre on the other side of the board. This line was played by G.Kasparov. Nowadays, V.Topa lov, A.Grischuk, T.Radjabov and many others try it in the tourna ment practice. At first, Black based his hopes on undermining his opponent's pawn-centre with the move e7-e6 (after d4-d5). Later however, it became clear that after the ex change on d5, White did not cap ture with his c-pawn, leading to

Naturally, the eS-square cannot be a reliable outpost for Black's knight, since White can oust it at any moment with the move f2-f4.

After this move, there arise po sitions which are more typical for the Benko Gambit. Its version is much more favourable for White, because he has already advanced e2-e4, having avoided the trade of his light-squared bishops, which usually happens in the Benko Gambit. The only minimal defect of his position is the placement of his bishop on gS. After the ap pearance of Black's queen on aS, White will have to lose a tempo to retreat his bishop to the d2square.

Chapter 11 Conclusion We have just completed the analysis of the variation with 6 . . . c5 in the Averbakh system of the King's Indian Defence. Black has many different possibilities in it, but only the ousting of the enemy bishop from its active position with the move 7 . . . h6 provides him with some chances of obtaining an acceptable game. Still, in this variation White maintains an edge due to the vulnerability of the ene my pawn on d6. After the move 7 . . . b5, there arise variations of the Ben ko Gambit which are unfavourable for Black. White has already ad vanced e2-e4 and contrary to the variations of the Benko Gambit, he will not lose his castling rights after i.a6-fl. Following 7 . . . e6, there arises a standard position with a space ad vantage for White, who has a clear-cut plan for further actions. He needs to exchange the major pieces and transfer the game into an end game with minor pieces in which he will have excellent winning chanc es thanks to his extra space and two powerful bishops. His plan to play for a win is connected with occupying space with his queenside pawns (a4-a5), followed by a preparation of breaks - either with b3-b4, or with g2-g4.

Part 3 The Modern Defence l.d4 g6
In the third part of volume 2, we will analyse the move l g6. It has been played even back in the h 19 t century, but in the contem porary theory it has been named the Modern Defence and quite de servedly so. The point is that at first it did not lead to original po sitions and usually transposed to the King's Indian Defence. It was during the 60ies of the past cen tury when the move l.. .g6 was played sometimes by M.Botvinnik and a bit later by L.Ljuboevic and they began to use plans connected with pressure against White's centre (the d4-square) with ig7, tLlc6, or if White protects his d4pawn with the move tLlf3, then ig4. Black wishes to exploit the delay of development of his knight on g8, since in that case the diago•••
nal for his dark-squared bishop is opened and if White closes the position in the centre, Black can play f7-f5 immediately and not af ter the preliminary retreat of his knight from the f6-square as it happens in the King's Indian De fence. In Chapter 13, we will analyse the basic position of this varia tion, which arises after l.d4 g6 2.c4 .ig7 3.e4 d6 4.tLlc3. There, we will pay most attention to Black's three main responses : 4 e5, 4 lLlc6 and 4 lLld7. In Chapter 12 we will deal with the different possibilities for Black to avoid the main lines on moves 2 and 3. I would like to mention that White should not be in a hurry to develop his knight to the f3square, because then Black can transpose to the King's Indian Defence, having avoided the Averbakh system. In the contemporary tourna ment practice this move is played by numerous strong grandmas ters (indeed, mostly in games with a shorter time-control) : Sh. Mamedyarov, H.Nakamura, P. Svidler, A.Morozevich . . . ••

Conclusion We have just completed our analysis of Black's attempts to avoid entering the Modern Defence on his moves 2 and 3. White obtains an advantage in all the variations, but his play is not so simple at all. There are many intricacies in these positions and there may arise transposi tions to numerous other openings. In general, we have to mention that is is not advantageous for White to develop early his knight to the f3-square, because this will enable Black to exert pressure against the d4-square with the move ig4, or to transpose to the King's Indian Defence, avoiding the Averbakh system. The only exception is the move 3 . . . 'Llc6, because in this variation White plays 4.'Llf3, but after 4 . . . d6, he must advance immediately S.dS, with out waiting for Black to pin his knight with the move S . . . ig4.

rificed pawn and maintains better prospects. Black's king is vulner able and this might be an impor tant factor in the oncoming fight.
Conclusion We have just completed our analysis of the variations, beginning with the move 3 . . . d6 in the Modern Defence. In all the lines, White maintains a certain advantage. He only needs to know well the theory in order to find his way in the intricacies of the different variations. This chapter should help the readers to accomplish this task.

Parts 4 and 5 l.d4 d6
In the last two parts of this book, we will analyse openings which arise much more often af ter l.e4. The reason for this is that fol lowing l.d4 d6, White must play 2.e4 if he wishes to fight for the opening advantage and if Black transfers to the King's Indian De fence, to be able to continue with the variations which we have ana lysed in out previous volumes. Otherwise, for example after 2 .c4, Black would obtain a good game by playing 2 . . . e5, while after 2.lt:lf3 tt:Jf6 3.c4 g6, there arises the King's Indian Defence, but with a white knight on f3.

Here, Black has a great choice between different systems for development and after the most popular move for him in this posi tion 3 g6, there arises the Pirc Defence-Ufimtsev on the board. We devote to this possibility the fourth part of our book. -

Black's attempts to avoid the Pirc-Ufimtsev Defence will be dealt with in part 5. This book is intended mostly to suit the fans of the closed open ings ; nevertheless, the chapters 12 to 17 will be very helpful as well to the players w.ho like to begin their games with the move l.e4. 197
Part 4 The Pirc-Ufimtsev Defence l.d4 d6 2.e4 �f6 3.�c3 g6
This part of the book will be devoted to the Pirc-Ufimtsev De fence. This opening has been named after the Yugoslavian grandmas ter V.Pirc, although the Soviet master A.Ufimtsev has contribut ed greatly to its development as well. In fact, in some opening monographs you can see its name as "The Pirc-Ufimtsev Defence". It has long gone from the section of the incorrect openings into one of the most fashionable opening systems. It has been tested even at the top level, including in the World Championship matches. Naturally, the initial moves of this opening have been tried in chess games even before V.Pirc and 198
A.Ufimtsev, but the attitude to wards this system was neglectful. When V.Harousek played this opening and lost the game quick ly, W.Steinitz commented "If you try such an awkward opening, small wonder that you lose the game.". Nowadays, it is a quite different situation. The Pirc Ufimtsev Defence is used by nu merous strong grandmasters : V.Kramnik, V.Ivanchuk, Sh.Ma medyarov, A.Grischuk, A. Moro zevich etc. As a rule, Black is not striving to equalise right after the opening, but to obtain a compli cated and not so well analysed po sition, even if it may be a little worse, but with chances of seizing the initiative.
4.i.e3
This move is considered to be one of the most dangerous for Black and quite deservedly so. White is preparing his standard attack: 1Mfd2 , 0-0-0, f3, .ih6, h4 etc. Meanwhile, he does not un cover his plans and depending on Black's replies, White can occupy the centre - f2-f4 (as a rule after the preliminary move h2-h3). The move 4 ..ie3 has been tried and still is( ! ) by numerous players and I would like to mention among them E.Sveshnikov and M.Adams, who have contributed greatly with their games to the de velopment of the theory of this variation for White. It seems less flexible for him to play 4.f3, since White reveals his plans a bit too early. 4.f4 ! ? This is also a very good move - he occupies the centre. To
the players who would like to study this move, I would like to recommend volume 4 of the se ries "Opening for White Accord ing to Anand" under the edition of A.Halifman. In Chapter 14 we will analyse the move 4 . . . a6, which is the fa vourite line of V.Kramnik. The basic arguments for Black - 4 . . . .ig7 and 4 . . .c 6 will b e dealt with in Chapters 15 and 16. It is worth mentioning that de spite the fact that as a rule White obtains effortlessly an advantage in the opening, but there arise very complicated and not so well analysed positions. Contrary to many other openings, Black has a great choice of possibilities. Therefore, White should study this opening very seriously.

V.Kramnik likes to play this move and this is in a way a mark of quality. Black is preparing b7b5, but contrary to the move 4 . . . c6, after the development to the b7-square, his bishop will not be restricted by his own pawn and will exert pressure against White's centre. Black's main replies 4 . . . .ig7 and 4 . . . c6 will be analysed in the following chapters. There do not arise original po sitions after 4 . . . l2Jg4, since follow ing S . .igS h6 6 . .ih4 .ig7 7.�d2, a variation is reached, which will be analysed in the next chapter after the move-order - 4 . . .i.g7 S.�d2 l2Jg4. 200
It seems rather dubious for Black to choose 4 . . . e5 S.dxeS l2Jg4 (It would be a disaster for him to continue with S . . . dxeS?! 6.�xd8+ <.!lxd8 7.l2Jf3 l2Jg4 8 . .ig5+ f6 9.h3 fxgS 10.hxg4 i.e6 1l.l2Jxg5± and Black did not have any compensa tion for the pawn, Bannik - Levin, Kiev 1964.) 6 . .if4 l2Jxe5 (The end game is worse for Black following 6 . . . dxe5 7.�xd8+ <.!lxd8 8 . .ig3 l2Jd7 9 . .ic4 f6 10.h3 l2Jh6 11.f4 .id6 12.l2Jge2 l2Jb6 13 . .ib3;!;, White has powerful initiative. He only needs to castle and deploy his rooks on the d and f-files and Black will hardly complete the development of his pieces. His king is in the centre of the board and is seri ously endangered despite the trade of the queens, A.Sokolov Milovanovic, Ulcinj 1998.) 7.�d2 .
l.d4 d6 2.e4 0.f6 3. !i:J c3 g6 4 . .ie3 a6 5.h3 White is preparing to castle queenside and to exchange the dark-squared bishops (i.e3-h6), after which he will begin an attack on the kingside. Black can hardly create any counterplay, since the advance of his queenside pawns will not lead to an attack, but to the appearance of new weaknesses in his camp. 7 . . . i.g7 (He cannot equalise with 7 . . . i.e6 8.0-0-0 0.bd7 9.h4 h5 10.!i:Jh3;!; - White will transfer hos knight to the g5square after which he will trade it for Black's bishop.

Black will have great problems to organise counterplay and his kingside will be seriously endangered. Later, in the game Tkachiev - Gagunash vili, Saint Vincent 2005, there fol lowed: 13 . . . i.e6 14.0.ge2 !i:Je5 15. 0.d4 �e7 16. g5 !i:Jh5 17.f4 0.c4 18.�f2 !i:Jb6 19.i.e2 !i:Jg7 20 .h4± Black's fianchettoed knight does not beautify his position and he will hardly parry White's threats - f4-f5 or h4-h5.

Black lacks space and his pieces have occupied passive positions. In addition, he has no counter play, since advancing c7-c5 seems to be practically impossible for him.

White has more space, better de veloped pieces and can exploit the vulnerability of the dark squares in Black's camp (the consequence of the moves g6 and e6, which as a rule do not combine well togeth er).
5.h3 ! ? It would be too passive for Black to try 4 . . . 0.bd7 5.f4. It would be senseless for White to castle queenside, because the break through in the centre e4-e5, with a black knight on the d7-square, seems simpler and more effective.
This i s a "symmetrical" move. Indeed, if Black can afford a move with his rook pawn, White can do the same, can he not? He has tak en under control the important g4-square with his last move. Now, he can follow with a pawn201
Chapter 14 offensive on the kingside with the help of f2-f4, as well as with g2g4. In addition, Black cannot play now b7-b5 due to some tactical reasons.

Now, the h1-a8 diagonal is opened and Black fails to develop his bishop on b7. 6 . . . lt:\fd7 (The retreat of the knight at the edge of the board to the hS-square - 6 . . . lt:\h5, seems very dubious, since after 7.W!f3 E:a7 8.d5 E:b7, in the game Lech tynsky - Schou Moldt, Teplice 2012, White could have reached a winning position after 9.e6! fxe6 10.dxe6 lt:\f6 ll.g4+- and the threat g4-g5, would have forced Black to part with his knight.

Conclusion We have just completed our analysis of the variation with 4 . . . a6 in the Pirc Defence. It has been used once in a while even by Kramnik (but indeed, mainly in games with a shorter time-control, or in games where he had to win necessarily with Black). In general, White obtains rather easily a considerable advantage. Black's main problem is that having played a7-a6, he has great problems following this with b7-b5, because White has the powerful tactical resource - e4-e5 with the move �f3 coming next and Black fails to develop his bishop to the b7-square. If he is not in a hurry to play b7-b5, then White simply completes his de velopment and his advantage is doubtless thanks to his powerful pawn centre.

This move has been played nu merous times and by grandmas ters like V.lvanchuk, A.Beliavsky, V.Topalov, P.Nikolic, A.Khalif man and many others. It seems quite natural, does it not? It looks like if Black has played g7-g6, he should follow with �g7. Still, things are not so simple at all. The point is that after
5.�d2 White has a clear-cut plan for his further actions, connected with the exchange of the dark squared bishops after .ih6, fol lowed by castling queenside. After that, there often arise positions with opposite sides castling and pawn-offensives on the different flanks. White's prospects are pref206
erable, since he has more space and in many variations he can oust the enemy knight on f6 (pro tecting the h7-pawn) with the move e4-e5, organizing a crush ing attack against the enemy king This is the difference between this variation of the Pirc Defence and the similar types of positions, with opposite sides castling, aris ing in the Dragon variation of the Sicilian Defence. White does not have there a pawn on d4 (it has been exchanged there for Black's c-pawn). It is due to this reason that many players, who like this position for Black in the Pirc De fence, postpone the development of the bishop on g7 and prefer the move 4 . . . c6 - we will analyse this variation in our next chapter. we Now, Black has numerous possibilities.

(diagram) In the game Pert - McNab, England 20110White overlooked the possibilitY to obtain a great advantage. Black's pieces can
hardly hold the defence on the queenside. This enables White to win a pawn on the other side of the board and in order to do this, he only needs to trade the knights. 24.�f3 ! �xf3+ (After 24 . . . lt:Jxe4 25.lt:Jxe5+ dxeS 26.'Wg7±, the po sition is opened and the misplace ment of Black's king in the centre of the board becomes the decisive factor.) 25.gxf3 ggs 26.�g4± After the exchange of the knight Black loses his h7-pawn and if we have in mind that White's king is much safer, Black's situation be comes critical.
Conclusion We have just finished the analysis of variations of the Pirc Defence with the move 4 . . . i.g7. As a rule, White obtains effortlessly an advan tage exploiting the too early development of Black's dark-squared bish op. After 5.'Wd2, Black can castle kingside and after that there arise complicated positions with mutual attacks on the different sides of the board. White's prospects in that case are clearly preferable. He follows with 0-0-0, f3, h4, i.h6, hS and organises a powerful attack on the h file. Meanwhile, Black's attack on the queenside often reaches its dead end, since White can easily protect his main weakness on this side of the board - the pawn on a2 (�bl and lt:Jcl). If Black decides to leave his king in the centre, then after ih6 and the trade of the bishops, in many variations the vulnerability of his h7-pawn becomes a telling factor. 230

strength you can judge by the fact that it has been used by the World Champions G.Kasparov and V. Anand. The idea of this move is at first to prevent the pawn-advance b7-b5. White takes under control the g4-square and prepares e4-e5. Meanwhile, his last move will be useful if he advances f2-f4 and g2g4. With this move Black prepares b7-b5, which may be useful if White castles queenside. Mean while, he postpones the develop ment of his king's bishop, which deprives White of his standard plan, connected with '1Wd2 and ih6, since exchanging the still not developed bishop would seem a bit strange. The move 4 . . . c6 is rather pop ular among the fans of the Pirc Defence. It has been played by P. Svidler, Sh.Mamedyarov, V.Ivan chuk, Z.Azmaiparashvili, M.Gu revich, A.Beliavsky and some oth er grandmasters.

Conclusion We have just analysed the variation with 4 . . . c6 in the Pirc Defence. After S.h3, White obtains an advantage in the opening, because Black cannot play S . . . bS due to 6.e5 ! and his pawn-offensive on the queenside leads only to the appearance of weaknesses in his camp. After Black's other possibilities, White completes effortlessly the development of his kingside and under the cover of his powerful pawn-centre begins an attack against the enemy king with \Wel-h4, fS, �h6 and 'DgS.

Surprisingly for many people, this move became very popular at the beginning of the 21st century. Numerous grandmasters have be gun to use it: A.Morozevich, T.

Some readers may ask them selves: "Is it not simpler and bet ter just to play 4.lt:Jf3?" and there will arise a position resembling the closed openings. White's pawns have occupied the centre and his knights are placed on c3 and f3, just like in the majority of the variations of the King's Indian Defence. This similarity is mis leading, however. The difference is in the placement of White's c pawn. It is not on c4, like in the closed openings, but on its initial square and does not participate in the fight for the centre. His knight on c3 must protect the e4-pawn and cannot be removed easily from c3, so White's prospects to advance c2-c4 in the middle game are just minimal.

This is the most natural move. White not only develops his bish op to an active position, but pre pares castling queenside, winning a tempo for development, since his rook will give a check to the enemy king (The fact that the dB square is not the best for Black's monarch is one of the pluses of the early trade of the queens.). Naturally, all this is very good for White, but we should not forget that there are no pawn weakness es in Black's camp and if he suc ceeds in completing his develop ment, White's advantage may evaporate. Therefore, he must play very precisely and energeti cally in this variation. Black has a great choice of possibilities in the arising posi244
This is not the best move for Black. Now, White's game is easy and he obtains an edge effortless ly. He only needs to play tt:\b5 at the right moment and to exchange on d6. White will not only obtain the two-bishop advantage in the process, but will provoke a weak ening of Black's pawn-structure.

variations which we have ana lysed in this chapter, White's two powerful bishops provide him with a slight edge.
Conclusion We have just completed our analysis of the variation with 3 . . . e5 4. dxeS. There arises after it an endgame which is slightly better for White and he maintains the initiative thanks to his superior development. Depending on Black's responses, White can fight for the advantage in two different ways. Following 6 . . . c6, he develops his bishop to c4, his knight on f3 and castles queenside. Later, he squeezes his opponent with the protection of the pawn on eS with the help of placing his bishop on the g3-square. Subsequently, White doubles his rooks on the d-file and transfers his knight along the route f3-el-d3-c5 and if Black protects his pawn on eS with the move f7-f6, then White transfers his bishop on f2 (after f2-f3). All this guarantees for him a slight but long lasting advantage in the endgame. In response to 6 . . . .ie6, White prepares the pawn-advance f2-f4 with the move g2-g3 and forces again his opponent to adhere to a passive defence. In general, it is much easier for White to play this endgame.

l.d4 d6 2.e4 �f6 3.�c3 �bd7
This move is simple and strong! H .Pillsbury played like this back in the year 1902. White is preparing e4-e5 and wishes to exploit the basic draw back of Black's third move - the absence of the d7-square for the retreat of his knight on f6.
4 .. e5 .
It is easily understandable that with his last move Black prepares the pawn-advance e7-e5, avoiding the exchange on eS with a transfer into an endgame, which we have just analysed in our previous chapter. As a rule, the move 3 . . . ltlbd7 is usually chosen by chess players in a fighting spirit, who strive for complicated positions with many pieces on the board, irrelevant of the colour of pieces they play with. A.Morozevich, D.Khisma tullin and some other grandmas ters play like this. White cannot enter now a slightly better end game, but has some other promis ing possibilities.
4.f4
This is a logical move. Black has played 3 . . . ltlbd7 in order to advance e7-e5. His other possibilities are not only inconsistent, but are just du bious. For example: 4 . . . g6? ! S.eS lLlhS 6.�e2 ltlg7 7.ltlf3± Black has wast ed too many tempi for the com pletely useless fianchettoing of his knight. White has a powerful pawn-centre and a lead in devel opment. Or 4 . . . c5? !

Chapter 18 exd6 exd6 8 . .id2 ! White plans to castle queenside. Now, Black will be faced with a rather unpleasant choice.

Black's bishop on c8, just like in the French De fence, is not so active as his oppo nent's bishop on d3, because it is severely restricted by his own pawns on b7, c6 and dS.

Conclusion Black's main idea in the variation with 3 . . . lLlbd7 is to avoid the slightly inferior endgame, arising after 3 . . . e5 4.dxe5. Following 4.f4, White creates serious problems for Black. He must either play a worse middle game (often with a "bad" knight on h6) or enter a very difficult endgame in which White has a much more active bishop ( d3 against a black bishop on c8) and a quite clear plan for active actions - advanc ing his kingside pawns - g4, fS. Naturally, it cannot be asserted that the endgame is winning for White, but no doubt his game is much more pleasant, while Black is forced to adhere for a long time only to a pas sive defence without any practical chances of seizing the initiative.

This move is relatively seldom played in the contemporary tour nament practice. It is considered that Black can hardly obtain an acceptable position with it. In deed, he does not fight for the centre so actively and his pieces do not enter the actions so quick ly. On the other hand, it has been played by strong grandmasters like Sh.Mamedyarov, V.Bologan, Z.Azmaiparashvili etc. At the be ginning of his chess career M. Adams played often like this.

Conclusion As a rule, in the variation with 3 . . . c6 White obtains effortlessly an
opening advantage. After 4.f4, Black has two main responses : 4 . . . g6 and 4 . . . '\WaS. In the first case, there arise favourable for White positions from the Pirc Defence, since Black has played the move c7-c6, which is not so necessary in this opening. Still, White must react very carefully and defend reliably his d4-square. In the second line (after 4 ... '\WaS), the position usually transfers into an endgame which is slightly better for White, or there arise situations of a "French" type, in which White maintains an edge thanks to his superior development and extra space. 283
