X0 French Winawer, Advance, 6...Ne7, Poisonned pawn, Konstantinoply variation [C19]

1.e4 X1 e6 X2 2.d4 X3 d5 X4 3.Nc3 X5 Bb4 X6 4.e5 X7 c5 X8 5.a3 X9 Bxc3+ X10 6.bxc3 X11 Ne7 X12 7.Qg4 X13 Qc7 X14 8.Qxg7 X15 Rg8 X16 9.Qxh7 X17 cxd4 X18 10.Ne2 X19 Nbc6 X20 11.f4 X21 Bd7 X22 12.Qd3 X23

We are always in the main variation.

12...dxc3 X24 13.Rb1 X25

[ The other choice is: 13.Nxc3 X26 a6 X27 14.Rb1 X28 Na5 X29 15.h4 X30 For example: 15...Nf5 X31 16.Rh3 X32 0-0-0 X33 17.h5 X34 Rg4 X35 18.Nd1!?N X36 Lutz, Christopher (2595) - Uhlmann, Wolgang (2495) 1-0 (53 m.) [C18] Dresden zt 1.2 01.05.1998.]

13...0-0-0 X37 14.Nxc3 X38 Na5 X39 15.h3 X40

One of many alternatives.

[ Most usual is: 15.Nb5 X41 Bxb5 X42 16.Rxb5 X43 Kb8 X44 And it may follow: 17.g3 X45 Rc8 X46 18.Be3 X47 Nc4 X48 19.Bf2 X49 Qc6 X50 20.Rc5 X51 Qa6 X52 21.Be2 X53 +/= Areshchenko, Alexander (2570) - Williams, Simon Kim (2487) 1-0 [C18] Coventry op 28.03.2005]

15...Kb8 X54 16.g4 X55 Rc8 X56 17.Nb5 X57 Bxb5 X58 18.Rxb5 X59 a6 X60 19.Rb1!? X61

Maybe a novelty.

[ Has been played by correspondence: 19.Rb2 X62 Nc4 X63 20.Rb1 X64 Qc5 X65 21.Qc3 X66 Qa7 X67 22.Rh2 X68 Ka8 X69 23.Qb3 X70 +/= Lehikoinen, Pertti Ilari - Tomacevic, M Radovan 1/2-1/2 (33 m.) [C18] Alekhine mem-A corr 9196 1991 ]

19...Nc4 X71

A thematic move in this position.

20.Qc3 X72

Equally a Thematic reply; it is not quite clear if White has interest in exchanging the f1-Bishop with the aggressive Black Knight.

20...d4!? X73

This pawn sacrifice is courageous and temerarious.

21.Qxd4 X74 Rgd8 X75 22.Qxc4! X76

The best reply; with two extra-pawns exchanging pieces is not risky for White.

22...Qa5+ X77 23.Qb4 X78 Qd5 X79

[ White wins easily after the Queen exchange: 23...Qxb4+ X80 24.axb4 X81 Rxc2 X82 25.b5 X83 axb5 X84 26.Bxb5 X85 Rd4 X86 27.0-0 X87 + -]

24.Be3? X88

A serious inaccuracy!

[ By the immediat check in b7, White takes a decisive advantage: 24.Qxb7+ X89 Qxb7 X90 25.Rxb7+ X91 Kxb7 X92 26.c4!+- X93 ]

24...Qf3? X94

[ Now the best way for Black is to take the unprotected h1-Rook: 24...Qxh1! X95 25.Qb6 X96 Rc7! X97 26.Qxa6 X98 Qf3 X99 27.Qe2 X100 Qxe2+ X101 28.Bxe2 X102 Rxc2 X103 +/= and then White is most likely able to hold the position.]

25.Qxb7+! X104

+ - Of course!

25...Qxb7 X105 26.Rxb7+ X106 Kxb7 X107 27.Bd3 X108

In such a position we observ the power of the pair of Bishops.

27...Nd5 X109 28.Bd2 X110 Nc3 X111 29.Kf2 X112

Well done! White King is secure and may envisage to take part to the ending.

29...Rd4 X113 30.Ke3 X114 Ra4 X115 31.Bxc3 X116 Rxc3 X117 32.h4! X118

The passed h-pawn go toward the promotion.

32...Raxa3 X119

33.Kd4 X120 Rc8 X121 34.h5 X122 Ra4+ X123 35.Ke3 X124 a5 X125 36.h6 X126 Rb4 X127 37.g5!? X128

[ May be considered: 37.h7! X129 Rh8 X130 38.g5 X131 Kc6 X132 39.c3 X133 +- with a technical endgame favourable to White.]

37...a4 X134 38.h7 X135

[ Seems to be rather strong: 38.f5 X136 exf5 X137 39.Bxf5 X138 Re8 X139 40.h7 X140 Rxe5+ X141 41.Kd3 X142 Re8 X143 42.h8Q X144 Rxh8 X145 43.Rxh8 X146 Rb5 X147 44.g6! X148 + - and White probably wins.]

38...Rh8 X149 39.Ra1 X150 Kb6 X151 40.c3 X152 Rb3 X153 41.Rxa4 X154 Rxc3 X155 42.Kd2 X156 Rxd3+! X157 43.Kxd3 X158 Rxh7 X159 44.Ra8 X160 Kb7 X161 45.Ra1 X162 Rh3+ X163 46.Ke2 X164 Rc3 X165 47.Rh1 X166 Kc8 X167 48.Rh7! X168 Rc7 X169 49.g6! X170

The winning move!

49...fxg6 X171 50.Rxc7+ X172 Kxc7 X173 51.Kf3

1-0
