Augalv: Gashimov Vugar - Karjakin Sergey, Grand Prix Baku, 10th Round. 1.e4 c5 2.Nc3 d6 3.d4 cxd4 4.Qxd4 Nc6 5.Bb5 Bd7 6.Bxc6 Bxc6 7.Bg5 h6 8.Be3 Nf6 9.Nf3 e5 10.Qd3 Be7 ( diagram )  click for larger viewPleasant position for Black.He faces a fine choice, to push d5 or b5.Somehow it seems that White need to be careful not to find himself in bad position. 11.Nh4?!
This just can't work.11.0-0 is best thing to do right here. 11..d5
Nothing to add, another option is 11..Nxe4 12.Nxe4 d5 13.Nf5 dxe4 14.Nxg7+ Kf8 15.Qxd8+ Bxd8 16.Nf5. 12.exd5 Nxd5 ( diagram )
 click for larger viewBlack is better, total failure of White's opening strategy. 13.Nf5
Not 13.Nxd5 Qxd5 14.Qxd5 Bxd5 with huge edge for Black. 13..Bb4! 14.0-0-0
If 14.Bd2 then 14..Bxc3 15.bxc3 g6 is better for Black. 14..Bxc3 15.bxc3 0-0 16.c4 Nxe3 17.Qxd8 Raxd8 18.Nxe3 f6 19.Rd3 Kf7?! This is not the most precise.19..Be4! is better.
20.Rhd1 Rxd3 21.cxd3 Rd8 22.f3 ( diagram )
 click for larger viewMore or less forced.Black is a bit better, no doubts about this.Better light piece, better pawn structure, majority on Kingside.To access White position Black must start to roll his 4 pawns, f3 pawn is nice target and is helping Black to establish desirable structure like f4+g4 to follow ( supported by h5 pawn ).For start is interesting 22..Ke6 with f5-g5-h5.White plan is to march King to c3 and to push d4.Black must stop this. Black's dream is to make position like in the next diagram.But how? If 22..Ke6 then 23.Kb2! ( 23.Rd2 is a waste of time, 23..f5! 24.Kc2 f4 25.Ng4 h5 26.Nf2 g5 goes into position from diagram ) with quick d4. What about 22..h5!? White can't reply with 23.h4? Rd4! is better for Karjakin.If 24.Kd2 h4 25.h3 Kg6 trying to enter via g5-f4 squares. Karjakin is trying to combine play on both flanks.

If 26..h5 27.Nf2 g5 28.Kc3 bxc4 ( if 28..g4 then 29.cxb5! ) 29.dxc4 Rxd2+ 30.Kxd2 and White is holding. 27.dxc4 Rxd2+ 28.Kxd2 e4 29.fxe4 Bxe4 ( diagram )
