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.)

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...

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...

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 .)

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.)
