Augalv: Karjakin Sergey - Jakovenko Dmitry, Aeroflot 2008, 4th Round. 1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.Nc3 Nxc3 6.dxc3 Be7 7.Bf4 O-O 8.Qd2 Nd7 9.O-O-O Nc5 10.Be3 Re8 11.Bc4 Be6 12.Bxe6 Nxe6 13.h4 Qd7 14.Qd3 Qc6 15.Qf5 Qc4 16.Kb1 g6 17.Qh3 h5 18.Nd2 Qe2 19.Rde1 Qg4 20.Qh2 d5 21.f3 Qa4 22.g4 Bd6 Players are showing great theoretical knowledge, this is all known. 23.Qg1
23.Qf2 Ng7 24.c4 dxc4 is older try and it ended with draw. 23..Ng7 24.Nb3 Qd7 25.Rd1
25..hxg4!?
First big crossroad, Black had another solid move 25..c6.Now 26.Bc1 is interesting and askes for futher investigation, other try is 26.Bd4 hxg4 27.fxg4 Re4 28.h5 Rxg4 29.Qf1 This is really sharp position.29..gxh5 ( 29..Qf5? is not wise due to 30.h6! Qxf1 31.Rdxf1 Nh5 32.h7+ Kxh7 33.Rxf7+ Kg8 34.Rd7 Bf8 35.Rxb7 with permanent advantage ) ( 29..Nxh5!? 30.Qf6 Rxd4 31.Qxd4 is unclear ) 30.Bxg7 Kxg7 31.Rxh5 Rg8 32.Nd4 Kf8 33.Qh1 with compensation.
Well, game took other direction.
26. fxg4 Re4
26..c6 is slow, White comes first with 27.h5.

Mistake.First what comes into brain is 28..a5 but 29.h5 a4 30.Rxe4 dxe4 31.Nd4 is better for White.28..Re1 is the best 29.Qxe1 ( 29.Qg2 trying to keep all forces on board is interesting ) 29.. Rxe1 30.Rxe1 c6 31.h5 is unclear. 29.Rxe4 dxe4 30.h5
White is first, problems are ahead for Black.
30..gxh5 31.gxh5 Kh8 32.Qg5 f6
32..Qe6 33.Nc5 Qd5 34.Be3 keeping the initiative.
33.Qh6+ Kg8 34.Rg1 Qf7 35.Nd4 Knight comes in, it's the beggining of the end. 35..f5?!
Not the best solution, 35..Bxd4 36. cxd4 Re6 37.Rg6 Rd6 38.Be3 but it's clear who's the boss here. 36.Bf4 Bxf4?
Last slip.More stubborn is 36..e3 37.Bxe3 f4 38.Bf2.
37.Qxf4 Kh7
37..Kf8 trying to escape is not working, 38.h6 Ne6 39.Qh4 Qh7 40.Qf6+ Qf7 41.Nxe6+ Rxe6 42.Qh8+ Ke7 43.Rg7 is winning. 38.Rg6 38..Re7 39.Qh6+ Kg8 40.Qg5 Kh7 ( diagram )
