without queens!
[ Instead, 42.dd8 xg1 43.xf8 f1+
leads to a draw with 44.e3 e1+ 45.d3 d1+ etc, since 46.c3 c2+ 47.xb3 xc8 48.xc8 h1 gets White nowhere. ]
42...gxf5 43.exf5 gd2 44.e1 bc2 [ 44...b4 is no better, since 45.e3 g2 46.d1 bc2 47.b8 b2 48.dd8 b1
49.g8+ is mate in two. ] 45.f6+! g6
[ 45...g8 fails to 46.c5! xc5 47.g1+
h7 48.xf8 and White has a decisive attack. ]
46.xf8 b2 47.e3 c1 48.g1+!
[ It is not too late to bungle it with 48.b8??
xe1 49.xd2 b1 and Black is winning. ] 48...f5
[ 48...xg1 49.g8+ f5 50.xg1 is the key point, when White controls the first rank and wins. ]
49.g5+ e6 50.e8+ d7 51.e6+! fxe6 Other moves are equally futile.
[ Black gets mated after 51...xe8 52.g8# ] [ or 51...c7 52.f4+ b7 53.b5+ a7 54.e3+ a6 55.a8# ]

52.b8 f1+ 53.e4 c7 54.gb5 h2 55.f4+ . After a long resistance, Black finally
has to lay down his arms.

[Damian Lemos]
1.f3 f6 2.c4 g6 3.g3 g7 4.g2 0-0 5.0-0 d6 6.d4 bd7 7.c3 e5 8.h3 c6 9.e4 b6 Putting more pressure on White’s
centre. 10.e1 I like this solid move for White because it is flexible.
[ Alternatively, 10.c5!? dxc5 11.dxe5 e8 12.e6 has been played a lot. If you want to
study this ultra-sharp line, I recommend starting with the game A.Shirov-G.Kasparov, Linares 1993. ]
10...exd4 The most consistent continuation, opening lines for piece-play.
[ If Black delays further with 10...e8
, White can close the centre and gain space with 11.d5!? , since the thematic response ...
f5 (backed up by a rook on f8) would now take Black a long time. Instead, after c5 12.b1! a5 13.e3 c7 14.d2 d7 15.f1! (a useful manoeuvre in the
Fianchetto System; from f1 the bishop
exerts controls over both the kingside and queenside) eb8 16.dxc6 bxc6 17.xc5 dxc5 18.b3 f8 19.a4! White had a
clear positional advantage in Z.Ribli-H.
Olafsson, Buenos Aires Olympiad 1978. ] 11.xd4 e8
[ Black has two main alternatives here:
11...e8 12.c2 e5 13.b3 was seen in another of Karpov’s games, which continued e6 14.a4 c7 15.d4 ad8 16.xe6 xe6 (White has obtained the bishop pair
and still has much more space) 17.c2 e7 18.a3 c5 19.c3 c6 20.ad1 d4 21.d3 and White had a slight
advantage, A.Karpov-G.Kamsky, Monte Carlo (blindfold rapid) 1995. ]
[ 11...g4 12.ce2! ( after 12.xg4 xd4 , White would have a hard time defending the c4-pawn ) 12...ge5 13.b3 c5 14.e3 (here White has everything under
control and will eventually push Black’s knights back):
A) 14...e8 15.b1 a5 16.a3
(White now has the option of both b3-b4 and f2-f4) c7 17.c2 e7 18.b4
( but I believe White can improve his game with 18.bd1 , ensuring a slight
advantage ) 18...axb4 19.axb4 cd3 20.ed1 c5 was unclear in R.Dive-F.
Rayner, Newcastle 1995.;
B) 14...a5 15.b1 e8 16.f1!
(pre-empting any tricks based on ...Nd3, and preparing f2-f4 to evict the centralized knight) d8 17.c2 e7 18.bd1 ( White does not need to play
extravagantly to keep the edge; for example, after 18.c3 ed7 19.fe1 f6 20.bd1 fd7 21.f4 d8 22.f2 b6 23.b1 c7 24.e2 b6 25.d1
, White was clearly better in S.Furman-R.
Nezhmetdinov, Tbilisi 1959 ) 18...h5 (Black doesn’t have much counterplay in the centre and if he does nothing, his position will slowly deteriorate as in Furman-Nezhmetdinov; so he tries
attacking on the kingside instead) 19.fe1 h4 20.g4 xg4?! (sacrificing a piece
offers Black only short-term
compensation) 21.hxg4 xg4 22.f4 h3 was played in A.Rustemov-A.Motylev, Russian Championship, St Petersburg 1998. Here GM Huzman gives the best defence as 23.xh3 h4 24.xg4 xg4+ 25.g3 xe4 26.f3 xd4+
27.g2! , when Black attack has been
repulsed. ]
12.f3 e5 Black lacks space and therefore tries to swap pieces off.
[ The active-looking 12...b4 is answered simply with 13.f1 , followed by a3 , pushing the queen back. ]
13.xe5 dxe5 14.a4
[ I would also consider playing 14.c2 c7 15.e3 a6 16.e2 White looks better
although Black's position is pretty solid ] 14...a5?! This move creates a hole on the
b6-square, virtually ruling out any quiet
continuation by Black, as he would just stand worse.
[ Instead:
14...f5?! 15.e3 c7 ( after 15...xb2 16.ac1! f4 17.c2 xc2 18.xc2 fxe3 19.xe3 , Black doesn't have enough for the
queen ) 16.exf5 gxf5 has only been tried once (in V.Bagirov-A.Yuneev, Leningrad 1989), because White could have played 17.c5 d6 ( or 17...f7 18.d5! ) 18.ad1 d8 19.xd6! xd6 20.d5!
with a clear advantage, since cxd5? loses to 21.e8+ f8 22.xd5+ e6 23.xe6+
h8 24.xd6 . ]
[ The safest continuation is 14...c7 15.e3 a6 ( not 15...xb2?? as 16.ec1
and Rab1 traps the queen, or if b5 then 17.a5! b4 18.a4 e2 19.xc7
M.Marin-Joh.Eriksson, Stockholm 2002. ]
15.a3! A useful move, controlling the b4-square.
[ 15.e3 is not possible yet, since xb2 shows the point of 14...a5: after 16.ec1 b4 , the black queen runs away safely. ] 15...c7 16.e3 xb2 A risky enterprise for
Black, but the alternatives were not great-looking anyway.
[ For instance, after 16...a6 17.f1
, the black queen can't be comfortable on a6, and e6 runs into 18.d5! cxd5 ( or 18...c5 19.b4 ) 19.cxd5 d6 20.dxe6 xe6 21.ed1 e7 22.ac1 with a definite edge
for White, since the a5-pawn is permanent weakness. ]
17.ec1 b5 The only move to save the queen. 18.d1! Obviously Qa5 is not possible here, but after this simple retreat, White wins material. bxc4 19.c5
[ 19.a4 b3 20.b6 e6 is less clear. ] 19...e6 There is no time to save the f8-rook
because of the threat of Rab1. 20.a4 [ White could still play 20.ab1 , but after xb1 21.xb1 xc5 , Black seems to have
some counterplay. He can protect the c4-pawn with ...Be6 and centralize the knight on the d4-outpost after ...Nb3. ]
20...b3 21.xf8 xf8 22.f1 Black has some activity although White is an exchange up. I believe the material advantage is more relevant in the long run d4 23.xc4
Although Black has a pawn and some activity for the exchange, I believe White's material advantage is more relevant in the long run.
xd1
[ 23...e6 24.c3 xd1 25.xd1 comes to the same thing. ]
24.xd1 e6 Lautier elects to keep his two bishops.
[ The alternative was to take the a-pawn:
24...xa3 25.b6 b8 26.xc8 ( 26.a4 b4 27.c4 c5! is not clear either )
26...xc8 27.a4 b4 28.c4 reaches a complex endgame, where it would be interesting to observe Karpov's technique. ] 25.c3 d8? This just wastes a tempo, since
Black changes his mind with the rook next move.
[ Therefore, Black’s best try is 25...b8 to control the open file, when Karpov's intended 26.c5 allows xh3! . ] [ Note that the attempted fork 25...b3?
just loses a piece to 26.xd4! . ] 26.g2 b8 27.c5 White gradually
improves his position; whereas Black doesn't have as much counterplay now and he's still down on material. b2 28.d3 a2
Safeguarding the bishop, and preventing White from playing Rb1 to trade pieces off.
29.a4 b3 30.a1! White forces exchanges anyway, which makes things easier for him. xc3 31.xc3 b3 32.e2 a4 33.f4 In Informator, Karpov stops
annotating at this point – presumably because, to him, the game was of no further interest.
For us, it's great to learn from the former world champion. As we pointed out before, White is interested in trading pieces (when appropriate), but we shouldn’t underestimate Black’s powerful bishop pair. b5 34.fxe5 g7!?
[ Taking the a-pawn with 34...xa3
would allow 35.d4! c5 36.xc6 c2 37.c1 e3+ 38.f3 and White should be
winning, although the position still requires accurate play. ]
35.c1 xe5 36.xc6
[ Giving up the bishop with 36.xb5 cxb5 37.c3 would have won a pawn, but after h5 ( 37...c4? fails to 38.xb5 xb5 39.c5 ) 38.xb5 f8 and ...Ke7, it is not
so easy for White to make progress against Black's strong bishops. ]
36...xa3 Black still has a pawn for the exchange and it seems as if he has some chances of resistance. However, Karpov finds a subtle way to play for the win. 37.g1!
White is ready to push the e5-bishop back!
Note too that Black’s knight is shut out of the game on a3. f8 38.f3 b2 39.d2 d1
[ 39...e6 40.a6 d7 is too passive to survive in the long run. ]
40.c7 e5 41.c5
[ With the black bishops where they are now, White could win with the switchback 41.c1 b3 42.xb3 axb3 43.c6 b2 44.b6
, followed by Rb3, when Black has to give up the b-pawn to save the knight; but Karpov probably wanted to avoid any long-winded rook vs. bishop endgame if at all possible. ] 41...d4 42.c8+ e7 43.c7+ e6?!
It is understandable that Black wants to bring his king into the centre, but it can't advance any further and will just be an easy target on e6.
[ Instead, 43...d6!? was a more interesting try,
A) as after 44.xf7 c2! , the black a-pawn becomes quite dangerous ( 44...-- );
B) but 44.c1! b3 45.xb3 axb3 46.c8 and Rb8 still wins, in spite of
Black's more active king. For example, b2 47.d8+! ( not now 47.b8? c5 48.b3 c4 ) 47...c5 48.d5+ b4 49.xd4+
c3 50.d7 c2 51.xc2 ( and not 51.b7?? e1+! ) 51...xc2 52.c7+!
(gaining a crucial tempo) d2 53.b7 c2 54.f3 b1 55.xb1 xb1 56.f4 c2 57.g5 d3 58.e5! (gaining more
time) e4 59.f6 d5 60.xf7 xe5 61.g7 and White wins. ]
44.f3 b2 45.b7!
[ The tempting 45.g5+ would allow Black to activate his forces by d6!
, with annoying counterplay after 46.b7 ( or 46.xf7 c2 ) 46...b3 47.xf7+ c5
. ]
45...c1 46.f2 h5 47.e2! b3 48.d4+
e5 49.xb3 axb3 50.xb3 xe4
51.d3+ . Black is defenceless against Ke2-d1, chasing away the protector of the errant knight. Therefore, he resigns here. Excellent technique by Karpov!

1.d4 f6 2.c4 g6 3.f3 g7 4.g3 0-0 5.g2 d6 6.0-0 bd7 7.c3 e5 8.e4
[ From this position, our move order would be 8.h3 c6 9.e4 a5 . But note that Black
sometimes plays ...c6 and ...Qa5 before ...
e5 and ...Nbd7, transposing here from Chapter Five (in which we play e2-e4 first).
As it happens, the final three games did take that route. ]
8...c6 9.h3 a5 10.e1
[ White's main alternative is 10.e3 . ] 10...exd4 Again, this is the most consistent
way for Black to carry out his plan.
[ 10...e8 would transpose to the main line (with 12..Re8)
A) after 11.e3 exd4 12.xd4 e5 13.f1 , but White has other options ( such as 13.e2!? );
B) or 11.d2!? b6 12.a4 d8 (having pushed the black queen back, White now completes his development) 13.c2 h5 14.e3 exd4 15.xd4
(the e4/c4 vs. d6/c6 pawn structure has finally appeared, and White enjoys a plus due to his space advantage) e5
16.ad1 c7 17.b3 f6 18.c3 ed7 19.f4 (White has built up a strong position,
while Black has achieved nothing at all) a5 20.f2 f8 21.d2 d7? 22.f3
and White won the d6-pawn and soon the game, A.Wojtkiewicz-G.Souleidis,
Duisburg 1999. ]
11.xd4 e5 12.f1 e6 Not the main try in the position, but definitely worth studying.
As White, we now get the bishop pair but must be careful, because Black has some tricks and most of our pieces are still on the back rank.
[ The usual move, 12...e8 , is the subject of Games 48 and 49 at the end of the
chapter. ]
13.xe6 fxe6 14.g2 Preparing the advance of the f-pawn to drive away the
centralized knight.
[ The immediate 14.f4?! runs into xc4!
and Black wins a pawn due to 15.xc4 c5+ and ...Qxc4. ]
[ I also like the natural 14.e3 for White, again preparing f2-f4. This is the subject of the next game. ]
14...ad8 15.f4 f7 16.a4! White has the bishop pair, so the endgame should be
favourable for him. Thus he aims for a risk-free advantage with queens off the board.
[ Another idea is 16.d2 b6 17.b3 c7 (Black wants to play with queens on!)
18.ad1 e5 19.e3 h5 ( but personally, I would play 19...exf4! 20.gxf4 e7 21.c2 h5 , when the position is unclear ) 20.f5 e7 21.e2 and White was clearly better in
L.Pantsulaia-T.Luukkonen, European Cup, Saint Vincent 2005. ]
16...xa4 I don’t like this move at all; trading queens is part of White’s strategy.
[ 16...c7? is clearly wrong, in view of 17.xa7 and White wins a pawn. ]
[ Black should play something like 16...b6 17.c2 ( 17.b3!? is also worth
considering ) 17...e5 18.e3 c7
, although White still has a slight edge after 19.e2 , preventing ...Nh5; while if Black
pushes ...d5, he opens up the position, which will favour our bishop pair. ] 17.xa4 e5 18.f5 gxf5 19.exf5 h5
Stopping White from playing g3-g4.
[ If instead 19...h6 20.xh6 xh6 21.g4 , White has a clear edge due to his
powerful bishop and strong kingside pawn majority. ]
20.e2 h7?! Beginning a faulty plan of attacking down the g-file.
[ Here I think Black should trade bishops with 20...h6 and then concentrate on his centre.
For example, 21.d3 ( or 21.c3 d5 ) 21...g7 22.c3 d5 23.cxd5 cxd5 , and if 24.b5 d7 25.xa7?! , then e4!
and the pawns are getting going. ]
21.e3 After this, White keeps his bishop pair as he can retreat down the g1-a7 diagonal if necessary. b6 22.c3 h6 23.f2! g8
[ 23...d5 24.cxd5 cxd5 25.ad1 g8 comes to the same thing. ]
24.ad1 d5 25.cxd5 cxd5 The position is still unclear, but given the chance I would take White's bishop pair. 26.b5 Heading for b3 to increase the pressure on the d5-pawn. g5 27.a4 e4? Black is losing thread of the
game. This allows White to blockade on d4
and the once proud centre will soon be demolished.
[ Perhaps Black wanted to take on f5 and was worried about something like 27...xf5 28.xd5 xd5 29.xd5 xd5? ( but 29...xf2+! 30.xf2 xd5 31.b3 b4
would save him here ) 30.c2 . ] [ Alternatively, he could switch his own
bishop to the queenside with 27...f8 28.b3 ( or 28.a3 c5 ) 28...b4
, when the game remains unclear. ] 28.d4! dg8
[ Unfortunately, 28...xf5? now loses to 29.f1 and White picks up a hapless
knight. ]
29.e2 g7 30.xf6 xf6 31.xd5
Finally cashing in on the booty. e5 32.c2 f3 33.ed1 e5? The final error.
[ 33...e8 was necessary. ]

1.f3 f6 2.c4 g6 3.g3 g7 4.g2 0-0 5.0-0 c6 6.d4 d6 7.c3 a5 8.h3
[ In Chapter Five, I give 8.e4 as being more accurate, when e5 9.h3 bd7 transposes below. ]
8...e5 9.e4 bd7 By a completely different route, we arrive at the same position as in the previous game. 10.e1 exd4 11.xd4 e5 12.f1 e6 13.xe6 fxe6 14.e3
[ An aggressive alternative to White's 14.g2 in the previous game. ]
14...ad8 This is the most natural move, simply defending the d-pawn. although Black has other possibilities too.
[ 14...d5 (I don’t think Black is ready for this, although accurate play is required by White) 15.cxd5 cxd5 ( if 15...exd5 , as in
S.Brynell-Po.Carlsson, Swedish Championship, Orebro 2013, then 16.f4 c4 17.xc4 dxc4 18.e5 d5 19.d4 leaves White with
the superior pawn structure, while Black’s g7-bishop doesn’t have much influence on the game ) 16.g2! ( this time 16.f4
allows Black some counterplay after c4 17.xc4 dxc4 , since his pawn is more
useful on e6 ) 16...ad8 ( or 16...xe4 17.xe4 dxe4 18.xe4 c4 19.b3 ) 17.exd5 xd5 18.xd5 exd5 19.f4
and, as usual, White’s two active bishops give him the upper hand. ]
[ 14...h5 15.e2 ad8 was played in B.
Bester-A.Copar, correspondence 2007, and here 16.g2! is simple and strong. White protects g3 before playing f2-f4 and thereby halts Black’s counterplay on the kingside. ] 15.f4
[ One of Black’s ideas is, if given time, to play 15.-- c5! 16.f4 c6 and a later ...Nd4, so
White should hit the knight straight away. ] 15...f7 16.g2 Its task on f1 completed, the
bishop returns to the long diagonal. d7 17.c1 b6
[ 17...xc3?! 18.xc3 xa2 can't be a good choice for Black. Yes, he's nabbed a pawn, but his kingside is now defenceless, and White's bishops are going to be much better than the knights in this open position.
Anyway, White can win the pawn straight back with 19.e2! a5 20.a3
and Rxa7. ]
[ 17...b4 18.e2 b6 is also ineffective.
After 19.d1 , as pointed out by GM Boris Avrukh in his excellent book 'Grandmaster Repertoire - 1.d4, volume two', White comfortably defends all his pawns and is ready to transfer his knight to f2. ]
18.b3 fe8 19.ed1
[ Here I think 19.c2 might be an
improvement, maintaining flexibility with the rooks. White’s position is very solid, so d5 shouldn’t be a problem for us. After 20.xb6 axb6 ( or 20...xb6+ 21.xb6 axb6
22.exd5 exd5 23.xe8+ xe8 24.cxd5 ) 21.exd5 exd5 ( or 21...d6!? 22.h2 f5 23.cc1! d4 24.a4 ) 22.xe8+ xe8 23.cxd5 , White has an extra pawn and no
weaknesses. ]
19...e5 20.f5 gxf5?! Black misses his chance to trade pieces off.
[ After 20...h6 21.xh6 c5+
( 21...xh6?? loses a piece to 22.c5+ ) 22.h2 xh6 , I think White is still better,
but the position is not as clear. ]
21.exf5 e4 This is too ambitious, though I can't suggest a better move for Black.
[ For instance, after 21...a6 22.f1!
(back again), Black's queen is misplaced in its little corner of the board. ]
22.xe4 xf5 The queen arrives on the kingside to aid the defence. However, White’s
bishop pair is too strong in this open position.
23.f1
[ 23.c5!? also came into consideration. ] 23...g6 24.f4! White increases his initiative,
preparing to double rooks on the f-file and setting up the threat of Rg4. d5
[ Moving the king out of the way with 24...h8 is weak in view of 25.c5
(attacking both knights) d5 26.g4 h5 27.f2 and White has a clear advantage ] 25.xb6 axb6 26.cxd5 cxd5
[ Black has no choice but to wreck his own pawn structure, as 26...xd5?
loses immediately to 27.cf1 h6 28.f6+
. ]
27.c7!? White has much better piece coordination and so is ready to attack.
However, Black has more resources than it might appear.
[ Instead, 27.f2 was a safe option for a slight advantage. ]
27...dxe4! 28.fxf7
[ 28.cxf7 is met by e6 (the only move)
[ Black loses after 29...h8? 30.xh7+
xh7 31.xh7+ xh7 32.f7+ h8 ( or 32...g7 33.xe4+ xe4 34.f5+ ) 33.xe4! xe4 34.h5+ g7 35.g5+
f7 36.xd8 e2+ 37.h1 and the checks will soon run out. ] 30.xe6
[ White could win a pawn by 30.xe4 xb3 ( not 30...xe4?? 31.f8+ xf8 32.f7# ) 31.xh7+ h8 32.axb3 , but then e2+
33.h1 e5! 34.cd7 xd7 35.xd7 xg3 should draw, especially as White has
the wrong bishop for his rook's pawn. ] 30...xe6 31.f1 e3?? After finding a series
of correct moves, Black makes a fatal blunder.
[ He should have inserted 31...c6! 32.xh7 ( not 32.xb7 c2+ 33.g2 e3 34.xh7?
f6! 35.h6 d6 and the passed pawn is suddenly decisive ) 32...e3 , when the position is still far from clear. ]
32.c4 e5
[ Black cant move the rook, because of 32...e5 33.g7+ f8 ( or 33...h8 34.xh7# ) 34.g8# . ]
33.xe6 xc7 34.xc7+ h8 35.c2 . White is now a piece up and the e-pawn is
going nowhere, so Black resigns.

Nice (blindfold rapid) (Game 48) 2009 [Damian Lemos]
1.c4 f6 2.c3 g6 3.g3 g7 4.g2 0-0 5.d4 d6 6.f3 c6 7.0-0 a5 8.e4 e5 9.h3 bd7 10.e1 exd4 11.xd4 e5 12.f1 e8 This is Black’s main move here. Rather
than playing ...Be6 at once (as in the previous two games), Black prepares it, in order to meet Nxe6 with ...Rxe6, keeping the e-file open. 13.e3 e6
[ Black has a tricky alternative here in 13...c5 , which is examined in the final game of the book. ]
14.xe6 xe6 15.g2!
[ White defends the f3-square in order to prevent ideas like 15.-- xe4! 16.xe4 xe1! 17.xe1 f3+ and wins. ]
15...ae8
[ After 15...a6 , White gets good play with 16.c5! (a strong pawn sacrifice in order to obtain a kingside majority; and following f4 and e5, White will have the e4-square available for his knight) dxc5 ( 16...d8 17.cxd6 exd6 18.a4 is good for White,
as pointed out by GM Avrukh ) 17.f4 d8 ( the piece sacrifice with 17...b4?!
doesn’t work here: 18.fxe5 xb2+ 19.f2 xc3 20.exf6 xf6 21.b1 b5 22.xc5
and White is winning ) 18.c2 ed7
19.ad1 b5 20.e5 ( the preparatory 20.f2!
looks even better ) 20...d5 , as in M.
Schachinger-A.Albadri, Austrian Championship, Vienna 2010, and now 21.f2 xc3 22.xc3 xc3 23.bxc3
gives White a clear advantage, due to his bishop pair and the ability to double rooks on the d-file. ]
16.b1! White prepares an expansion on the queenside. I started paying attention to this move when Ivanchuk played it. a6
[ Another advantageous line for White goes:
16...ed7 17.f3 a6 18.b4 d8 ( or 18...c7 19.c1 a5 20.a3 axb4 21.axb4 a8 22.b3 h5 23.f4 h7 24.c5! e5 25.cxd6 xd6 26.cd1 c7 27.xe5 xe5 28.f4 e7 29.e5 and White has a
clear space advantage, S.Vidit-P.Thipsay,
Indian Championship, Aurangabad 2011 ) 19.d2 h5 was seen in O.Cvitan-A.
Volokitin, Slovenian Team Championship 2004. Here White can improve his play with 20.c5! e7 21.cxd6 xd6 ( trading queens
with 21...xd6 22.ed1 xd2+ 23.xd2 makes things easier for White ) 22.c2 h4 (Black tries to create weaknesses on the kingside, but White has a powerful
rejoinder) 23.e5! xe5 24.f4 eg4!? ( or 24...ed7 25.c5 f8 26.xd6 xd6 27.xe8+ xe8 28.e4 ) 25.c5 ( 25.hxg4?! d7! 26.bd1 xg4
gives Black strong play for the piece ) 25...d8 26.xe8+ xe8 27.e4!
(winning the exchange) gf6 28.xd6 xd6 29.xf6+ xf6 30.d1 and White
has a clear advantage, in my opinion. ] 17.b4 c7 18.c1 b8 19.c5! It's the right
moment to advance on the queenside.
[ Instead, 19.a4 a5 20.b5 ed7 21.f3 c5 22.e2 fd7 23.f2 c7 was unclear in J.
Maherramzade-G.Bagaturov, Tbilisi 2001;
although White has the two bishops, Black’s dangerous knights shouldn’t be underestimated. ]
19...d8 20.cxd6?!
[ Here I think White can improve by moving the queen off the d-file, with either 20.c2 ] [ or 20.b3 . If Black responds by playing d5
, then after 21.exd5 cxd5 ( not 21...xd5 22.xd5 xd5? due to 23.f4 followed by 24
Bc4, skewering the rooks ) 22.cd1 , he is left with a vulnerable isolated d-pawn. ]
20...exd6 21.c2 b5?! I don’t like this move much, as it just creates weaknesses on the queenside.
[ Trading pieces off with 21...d3 22.xd3 xd3 is a better idea, when Black gets rid of
White’s bishop pair. After 23.cd1
( 23.d5? fails to xd5! 24.xd3 xb4 and 25...Nb3, regaining the exchange ) 23...xd1 24.xd1 xd1 25.xd1
, I think White may have a slight initiative, but Black has no weaknesses and so should be able to equalize soon. ]
22.ed1 xd1 23.xd1 xd1 24.xd1 Despite the exchange of all the rooks, White has the advantage again, due to his kingside pawn majority and bishop pair, not to mention Black's backward c-pawn. d6 25.f4
[ Another possibility was 25.c5 e6 26.f3 f8 27.xf8 xf8 28.e2 and White
improves his position little by little. ]
25...d4 26.f3 fd7 27.d2 c4?!
This weakens Black's pawns even further.
[ But 27...xd2+ doesn't solve his problems, as after 28.xd2 b6 29.f4 ec4 30.e1 , White keeps the better prospects due to his bishop pair. ]
28.xc4 bxc4 29.xd4 xd4 30.e3 b6 [ If 30...c3 , then 31.c2 , followed by
Kf1-e2-d3, and the c3-pawn will quickly fall. ] 31.f1 f6 32.e2 c5
[ Black loses the c4 pawn after 32...c3 33.a3 b2 34.c7! . ]
33.bxc5 xc5 34.c7 a4 35.a5!
Despite being a blindfold game, Ivanchuk shows excellent technique. The white bishop retreats to prevent the black knight from using the c3-square. c3
[ 35...xe3 36.xe3 c5 37.d4 e6+
38.xc4 g5 is equally hopeless, as after 39.c5 , followed by Kb6 and Kxa6, White's
a-pawn is much faster than any passed pawn Black might obtain on the kingside. ] 36.d5 f7 37.d3 d6 38.g4 e6 39.xc3 xc3 40.xc3 f5 41.d4 fxg4 42.hxg4 e5+
[ 42...h5 43.gxh5 gxh5 44.f4 also wins for White ]
43.e3 g5 44.d3 d6 45.d4 h2 46.a4 g1+ 47.c4 e5 48.b4 f4 49.xa6 xf3 50.e5 h2 51.e6 d6 52.d5
[ 52.c5! would have been more accurate, as after h5 53.a5 hxg4 54.a6 g3 55.a7 , the a-pawn promotes with check. ]
52...f8 53.b8 h5 This is Black's last chance.
[ After 53...xg4? 54.a5 , White's pawn is again much faster. ]
54.d7
[ 54.a5? hxg4 55.a6 doesn't work now, since the white king blocks the check on a8. ]
54...hxg4
[ If 54...e7 , then 55.e5+ f4 56.gxh5 g4 57.xg4 xg4 58.h6 wins. ]
55.xf8 g3 56.e7 g2 57.e8 g1
58.e4+ g3 59.e6 So Black has
managed to get a new queen as well. All the same, White is a piece up and – very
importantly – still has a pawn on the board and is therefore winning. The computer
