| Augalv: Shirov Alexey - Jakovenko Dmitry, Aerosvit 2008, 2nd Round. 1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.g3 Ba6 5.Qc2 c5 6.d5 exd5 7.cxd5 Bb7 8.Bg2 Nxd5 9.O-O Be7 10.Qe4 Bc6 11.Ne5 Nc7 11..Nf6 is older try, Jakovenko is willing to set his foot into new teritory. 12.Nxc6 dxc6 13.Nc3 O-O 14.Rd1 Qe8 15.Bf4 Ne6 16.Nb5 Qc8 More or less forced after 11..Nc7.It's clear that Black must give up his extra soldier in order to finish development. 17.Bxb8
Maybe White could wait a bit longer with this exchange 17.Nd6 Bxd6 18.Bxd6 Re8 19.e3 is interesting.17.Be3 Re8 is also worth considering. 17..Qxb8
17..Rxb8? 18.Nxa7 with edge.
18.Qxc6 Qe5 19.Qd7 Rae8 20.Nc3
Logical move keeping all targets in board, especially a7 pawn.20.Nxa7? is not precise, 20..Qxe2 and Black equalized. 20..Qb8 21.Nd5 Bd8
If 21..Bd6 22.e3 Rd8 23.Qb5 with tiny edge.22.Nf6+!? is other alternative. 22.e3 White is better, Black pieces are very clumsy and passive. 22..Nc7

This natural move throws away some of the advantage.Computer-like 23.Qd6! is strong 23..Qc8 24.Qc6! Qb8 25.Nc3! and White Rook can access seventh rank. 23..Nxd5 24.Bxd5 Bf6 25.Rad1 g6 26.Bc4 Kg7 27.b3 Re7 28.Qb5 h5 29.a4 h4 30.Qc6 hxg3 31.hxg3 Black is breathing more freely now but still he must work hard to fully equalize.Bishops can't oppose each other and that is in White's favour since he is more active side.It's clear that White must push his Kingside pawn to squeeze maximum out of position. 31..Rc8
31..Qc8!?
32.Qf3 Qe5 33.Rd5 Qc7 34.g4 Rh8 35.g5 Bb2 36.Kf1 Qb7 37.Ke2 Qc7 38.Qg4 ( diagram )  click for larger viewEverything according to plan but Black holds tight.
38..Bd4?
Major slip.Maybe time pressure? Strange looking 38..Qh2! is holding 39.Rd7 Rhe8! ( that's the idea, Black is threathening Rxe3+ ) 40.Rxe7 ( 40.R1d3 Bd4 ) 40..Rxe7 and White was forced to swap his attacking arsenal.Equal position. 39.Kd3 Be5 40.f4 Bd6 41.Qg2
Now it's a different story, Bishop is not longer controling a1-h8 diagonal. 41..a6
41..Ree8 42.Kc2 and White is much better.
42.Qb2+ Kg8 43.Kc2 Rh2+ 44.R5d2 Rxd2+ 45.Rxd2 b5 46.Qf6 1-0 Extracted from blog about Sergey Karjakin
