Commentary By GM Adrian Mikhalchishin
1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0–0 6.h3 c5 7.d5 e6 8.Bd3 exd5 9.cxd5 b5 10.Nxb5 [Very popular modern system against the Benoni. But the White reaction now is unexpected for Black. Much more popular nowadays is the line 10.Bxb5 Nxe4 11.Nxe4 Qa5+ 12.Nfd2 Qxb5 13.Nxd6 Qa6 14.N2c4 Nd7 15.0–0 Ne5 and Black hass compensation for the sacrificed pawn.]
10...Nxe4?! This move is too risky, but another plan does not guarantee equality e.g. 10...Re8 11.0–0 Nxe4 12.Qb3 a6 13.Na3 Nd7 14.Nc4 Rb8 15.Qc2 f5 16.Re1 Ndf6 17.Ng5 Nxd5 18.Bxe4 fxe4 19.Nxe4 Bf5 20.Qd1 Bxe4 21.Rxe4 Rxe4 22.Qxd5+ Kh8 23.Qxe4 d5 24.Qe2 dxc4 25.Qxc4 Qd1+ 26.Qf1 Qxf1+ 27.Kxf1 c4 28.Rb1!?N a5 29.Bf4 Rxb2 30.Rxb2 Bxb2 31.a4 Kg8 32.Ke2 Kf7 33.Kd2 Ke6 34.Bc7 and Black has huge problems in the endgame, Epishin,V (2579)-Nedev,T (2514)/Ohrid ) 2001 (38)
11.Bxe4 Re8
12.Nd2!? [Extremely interesting is the fact, that both players confirmed ,that they had forgotten the theory in this position! Here, one of the guests of the tournament GM and former Vice President of Barclays Bank, Aleksandr Volzhin claimed that in the end of eighties it was established that White obtain huge advantage after 12.Ng5! h6 13.Ne6 fxe6 (13...Qa5+ 14.Nc3 Bxc3+ 15.bxc3 Qxc3+ 16.Bd2 Qc4 17.Qf3 Bxe6 18.Rc1 Bg4 19.Rxc4 Bxf3 20.gxf3 f5 21.Rg1 Kh7 22.Bf4± Poluljahov,A (2360)-Glyanets,A (2380)/Moskva) 14.0–0]
12...Ba6 13.a4 f5 [Better was aggressive 13...Qa5 14.Nxd6 Nd7 15.Qc2 f5 16.Nxe8 Rxe8 17.Kd1 fxe4 18.Nxe4 c4!?N 19.Nc3 Bxc3 20.Qxc3 Qxd5+ 21.Bd2 Nc5 (21...Qxg2 22.Re1 Rxe1+ 23.Bxe1²) 22.Re1 Rxe1+?! (Equality promised just 22...Ne4 23.Rxe4 (23.Qa5?? Nxf2+ 24.Kc1 Rxe1+ 25.Bxe1 Qd1#; 23.Qe3 Rd8) 23...Qxe4 24.Qe3 (24.f3 Qe2+ 25.Kc2 Qxg2 26.Rd1 Qxh3 27.Kc1=) 24...Qc6 25.Qd4 Qxg2 26.Ra3 Qf1+ 27.Kc2 Bc8 28.Re3=) 23.Kxe1 Qxg2 24.Bh6 with Whites advantage. Vescovi,G (2633)-Jobava,B (2614)/Wijk aan Zee II 2006] 14.0–0 fxe4 15.Nc4
15...Be5 It is very difficult to recommend good defence here, as other move was terribly refuted [15...Bd4 16.Ncxd6 Rf8 17.Bh6 Bxb2 18.Bxf8 Bxa1 19.Qxa1 Qxf8 20.Qe5 Bxb5 21.axb5 a5 22.Nxe4 1–0 Graf,A (2629)-Ghaem Maghami,E (2549)/Moscow 2004] 16.Nxe5 [Possible was a bit different strategy 16.Re1 Bxb5 17.axb5 Nd7 18.Nxe5 Rxe5 19.Bf4 Re8 20.Bxd6 Qb6 21.Bg3 Qxb5 22.d6 Qc6 23.Qc2 Nb6 24.Ra3 a5 25.Rae3 c4 26.Rxe4 Rxe4 27.Rxe4 Re8 28.Rd4 Qc5 29.Rd1 Nd7 30.Rc1 Nb6 31.b3 Rc8 32.Qe4 Qf5 33.Qb7 cxb3 34.Rxc8+ Qxc8 35.Qxc8+ Nxc8 36.d7 1–0 Nikolov,M (2565)-Rabrenovic,V (2396)/Obrenovac 2010] 16...Rxe5 17.Bf4 Rf5 18.Bg3 Bxb5 19.axb5 Nd7
20.Re1 [Very tempting was 20.Bxd6 Qb6 21.Be7 Qxb5 22.d6 Qxb2 23.Qa4] 20...Nf6 21.Ra6! This strong position of the Rook is the main problem of Black in this situation. 21...Qe8 [Very bad position gets Black after 21...Rxd5 22.Qb3 Kh8 23.Rxe4 Nxe4 24.Qxd5 Nxg3 25.fxg3 Rb8 26.Rxd6] 22.Qa4 Rxd5 23.Qa2 [Stronger was 23.Bxd6 c4 24.Rc6] 23...c4 24.b6! Now the pawn on a7 decides the game. 24...Qb5 25.bxa7 Qc5 26.Bf4 Nd7 27.Rc1 [Also winning, but complicated was 27.Rxe4 Rd1+ 28.Kh2 Qxf2 29.Qxc4+ d5 30.Qc6] 27...Kg7 28.Be3 Qb5 29.Kh2 [Simpler was 29.Qxc4 Qxc4 30.Rxc4 Nc5 31.Rd4 Re5 32.Rc6 Rxa7 33.Rdxd6] 29...Ne5 30.Rb6 Qd7 31.Rb8
31...Nf3+ Last chance for Black. 32.Kg3 [Black would save the game after white accepted the sacrifice 32.gxf3 Rh5 33.Rb7 Rxh3+ 34.Kg1 Qxb7 35.Qxc4] 32...Rxa7 33.Qxc4 Rg5+ 34.Bxg5 Nxg5 35.Qg8+ Kh6 36.Qf8+ Kh5 37.Qf4! 1–0
