X0 Gruenfeld: Exchange variation [D85].

1.d4 X1 Nf6 X2 2.c4 X3 g6 X4 3.Nc3 X5 d5 X6 4.cxd5 X7 Nxd5 X8 5.Bd2 X9

[ The main line proceeds with: 5.e4 X10 Nxc3 X11 6.bxc3 X12 Bg7 X13 7.Nf3 X14 c5 X15 8.Rb1 X16 0-0 X17 ]

5...Nb6 X18

This reply, alternative to the usual 5...Bg7, has been introduced in 1988 and continues to be practised at all level.

[ May be played: 5...Bg7 X19 6.e4 X20 Nb6 X21 7.Be3 X22 0-0 X23 8.Be2 X24 Nc6 X25 9.Nf3 X26 Bg4 X27 10.d5 X28 Bxf3 X29 11.gxf3 X30 Ne5 X31 12.Qb3 X32 c6 X33 13.0-0-0 X34 = Kortchnoi, Victor (2625) - Svidler, Peter (2690) 1/2-1/2 [D90] Bad Homburg 20.07.1998.]

6.Bf4 X35

A strategic choice, played from time to time since 1993, less ambitious that the habitual 6.Bg5. One may add that this beginning led to some notable Black' s wins!

6...Bg7 X36 7.e3 X37 c5 X38

[ 7...0-0 X39 8.Nf3 X40 c5 X41 9.dxc5 X42 N6d7 X43 10.Rc1 X44 Nc6 X45 11.Bb5 X46 Nxc5 X47 12.0-0 X48 Bf5 X49 13.Qe2 X50 Bd3 X51 14.Bxd3 X52 Qxd3 X53 15.Rfd1 X54 Korchnoi, Victor - Spassky, Boris (45 m.) 0-1 [D85] St Petersburg m rapid 28.03.1999.]

8.dxc5?! X55 Bxc3+?! X56

It is not judicious to exchange the powerful g7-Bishop with the White Knight and I believe that the destruction of the White pawn-structure on the Queen side, is not a sufficient compensation.

[ It seems that Black equalizes after: 8...N6d7 X57 9.Nd5 X58 e5 X59 10.Bg3 X60 Nxc5 X61 11.Rc1 X62 Nba6 X63 12.Nf3 X64 Be6= X65 ]

9.bxc3 X66 Qxd1+ X67 10.Rxd1 X68 N6d7 X69 11.Bb5 X70 a6 X71 12.Ba4 X72 f6?! X73

Now White may defend quietly his extra pawn.

[ Better is probably: 12...Nc6 X74 13.Bc7 X75 0-0 X76 14.Bb6 X77 Nce5 X78 +/=]

13.Bxb8 X79 Rxb8 X80 14.Ne2 X81 e6 X82 15.Nd4 X83 Ke7 X84 16.Nb3 X85 f5 X86 17.Rd4 X87 Nf6 X88 18.Na5! X89

Black cannot advance the b-pawn according to the fork in c6

18...Ne4 X90

The most accurate answer.

19.Rc4 X91 e5?! X92

[ May be considered: 19...Bd7 X93 20.Bxd7 X94 Kxd7 X95 21.Nb3 X96 e5 X97 22.f3 X98 Nf6 X99 23.Ke2 X100 and White owns only a little advantage.]

20.f3! X101 Nf6 X102 21.Rb4 X103 Be6 X104 22.c4 X105 Rhc8 X106 23.0-0! X107

This very belated short castle is a nice decision. But this way White allows is opponent to catch the c4-pawn.

23...Nd7 X108 24.c6 X109 bxc6 X110 25.Rxb8 X111 Nxb8 X112 26.Rb1 X113 Kf6 X114 27.Kf2 X115 g5 X116 28.Rb6! X117

The most effective reply; White wins back his extra pawn!.

28...Nd7 X118 29.Rxc6 X119 Nc5 X120 30.Rxc8 X121 Bxc8 X122 31.Bc2! X123

In c2 the White Bishop forbids the intrusion of the Black Knight in the White camp via d3.

31...Ke7 X124 32.Ke2 X125 Kd6 X126 33.Kd2 X127 h5 X128 34.Kc3 X129 h4 X130 35.Nb3 X131 f4 X132 36.exf4 X133 exf4 X134 37.h3 X135 Bb7 X136 38.Bf5 X137 Bc6 X138 39.Kd4 X139 Ne6+?! X140

Ultimate fault

40.Bxe6 X141 Kxe6 X142 41.Nc5+ X143 Kf6 X144 42.Nxa6 X145 g4 X146 43.hxg4 X147 h3 X148 44.gxh3 X149 Bxf3 X150 45.Nc5

1-0
