1.d4 Nf6 2.c4 e6 3.Nc3 d5 4.Bg5 Bb4 5.Nf3 Nbd7 6.e3 c5 7.cxd5 exd5 8.Bd3 Qa5 9.Qc2 O-O 10.O-O c4 11.Bf5 g6 12.Bh3 Re8 13.Nd2 Bxc3 14.bxc3 Ne4 15.Nxe4 dxe4 16.Bxd7 ( Probably best. The old continuation is 16.Bh6?! Nf6 17.Bxc8 Raxc8 18.f3 Re7 19.Rac1 Rce8 Black has a slight advantage Dokhoian,Y-Arencibia Rodriguez,W/Pamplona 1991.)

16... Bxd7 17.Bf4 Finally White has got a tiny advantage mostly based in his future plans/ activity in the queenside. His passed d-pawn is not worthy much yet as there is no way to push it effectively. One must also note that thee are some weaknesses on the black squares around the black king and although opposite-coloured bishops helps in creating an attack, in this particular position this an illusion as White's pieces cannot cooperate in that project.

17... Bc6 ( Alternatively Black has tried: a) 17... Qd5 18.a4 Re6 19.Rfb1 Rb6 (19... a5 20.Qb2 Bc6 21.Qa3 Kg7 22.h3 White has a slight advantage Pinter,J-Sosonko,G/Haninge 1988) 20.Rxb6 axb6 21.Qb2 White has a slight advantage Cebalo,M-Wirthensohn,H Bern 1988.) ( b) 17... Ba4 18.Qb2 (18.Qd2 Qd5 19.f3 Re6 20.Rf2 f6 21.fxe4 Rxe4 22.Bg3 f5 23.Be5 Re8 24.h3 Bc6 25.Re1 Qe6 26.Rf4 g5 27.Rxe4 Bxe4 28.Qf2 h6 29.Qb2 White has a slight advantage Kalinin,O-Blatny,P/Warsaw 1989) 18... Bc6 19.a4 White has a slight advantage Vaisser,A-Wirthensohn,H/Suhr 1990.) ( c) 17... Re6 18.d5!? Ba4 (18... Qxd5 19.Rfd1 Qb5 20.Rd4 Bc6 21.Rad1 Re7 22.h3 White has sufficient compensation for material deficit) 19.Qd2 Rd8 20.d6 White has a slight advantage Grivas,E-Hector,J/Haifa 1989.) ( d) 17... Qf5 18.a4 b6 19.Rab1 g5 20.Be5 f6 21.Bg3 h5 22.h3 Qg6 23.Rb4 White has a slight advantage Peng,Z-Ioseliani,N/Manila 1992.) ( d) 17... f6 18.Rae1 (18.a4!) 18... Qd5 19.Bg3 Bc6 20.f3 Re6 21.Rf2 Rae8 22.fxe4 Qxe4 23.Qxe4 Bxe4 24.Rb2 Ra6 1/2-1/2 Galonska,J-Kilian,R/Ruhrgebiet 1999.)

18.Rfb1 ( Not bad also is 18.a4 Re6 (18... Kg7 19.Rfb1 Qd5 20.a5 g5 21.Bg3 Re6 22.Qe2 Kg6 23.Rb4 White has a slight advantage Titz,H-Giorgadze,G/Velden 1994) 19.Rfb1 g5 20.Bg3 h5 21.h3 h4 22.Be5 f6 23.Bh2 Qd5 24.Qe2 Kf7 25.Rb4 White has a slight advantage Smirnov,V-Alekseev,A/Minsk 1987) ( but not much is offered by 18.Rfc1 Bd5 19.Qe2 f6 20.Rab1 Re6 21.Rb4 Qa3 22.Qb2 Qxb2 23.Rxb2 Ra6 24.Kf1 Kf7 25.Ke2 Rd8 equal chances, quiet position Tania,S-Ulko,J/Moscow 2005.) ( It must be noted that 18.d5 is not that effective as in the previous note: 18... Qxd5 19.Rfd1 Qa5 20.Rd4 Rad8 21.Rad1 (21.Bd6 Rd7 22.Qd2 (22.Rad1?? Ba4 23.Rxe4 Red8 Black has a decisive advantage) 22... Re6) 21... Rxd4 22.Rxd4 Rd8 23.Bd6 (23.Qd2 Rxd4 24.Qxd4 Qd5 drawish position) 23... Rd7 24.Qd2 Qd8! 25.h3 f6 26.Bc5 b6 27.Rxd7 Qxd7 28.Qxd7 (28.Bd4 Kf7 Black has a slight advantage) 28... Bxd7 29.Bd6 g5 30.a3 Kf7 31.Bb8 a6 32.Bc7 b5 33.Bd8 h5 34.Kh2 Kg6 35.Kg3 1/2-1/2 Jussupow,A-Ivanchuk,V/Brussels 1991.)

18... Qd5 19.a4 (19.Qb2 Re6 20.Qb4 g5 21.Bc7 Rc8 22.Qa5 Qxa5 1/2-1/2 Kelly,B-Sosonko,G/Linares 1995.)

19... b6 20.Qa2 Qe6?! (20... Rac8 21.Rb4 Bd7 22.h3 White has a slight advantage looks like the best try for Black.)

21.Rb4 Bd5 22.a5! White has a moderate advantage Now White has created a lot of dangerous activity in the queenside.

22... bxa5 (22... Kg7 23.Qb1! White has a moderate advantage .)

23.Qxa5 Red8 24.Rb5 Rd7 25.h3 Black's weaknesses in her pawn-structure (a7,c4) and the lack of Black's counterplay will tell in the end.

25... Kg7 26.Qb4 Rad8 27.Raa5 h6 ( A bit better was 27... f6 28.Qa3 Qf7 29.Ra6 White has a moderate advantage .)

28.Qa3 Ra8 29.Be5+ f6?! (29... Kh7 30.Ra6 Qe8 31.Qa5 Be6 32.Qb4 Rd5 33.Rxd5 Bxd5 34.Qc5 Be6 35.Rxa7 Rxa7 36.Qxa7 White has a decisive advantage .)

30.Ra6! Now it's all over.

30... Bc6 31.Rc5?! ( Much better was 31.Qc5 Rc8 32.Rb8 Rxb8 33.Bxb8 White has a decisive advantage .)

31... Rc8 32.Bg3 Rb7? ( The last mistake. Although 32... Qe7 33.Qa5 Bb7 34.Rxc8 Bxc8 35.Rc6 White has a moderate advantage was far from ideal for Black it was the only chance to prolong the fight.)

33.d5! 1-0
