(1) Najer,Evgeniy (2633) – Smirin,Ilia (2644) [B67]

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf65.Nc3 Nc6 6.Bg5 e6 7.Qd2 a6 8.0-0-0 Bd79.f3 b5 10.Kb1 Be7 11.h4 0-0 11… Rc8 and 11…Ne5 are also very popular.

12…b4 13.Nce2 a5 14.Nxc6 Bxc6 15.Nd4Bb7 16.Bb5 Before starting active actions on the kingside white is trying to block opponents counterplay on the other side of the board.

16…Qc7 17.h5 Rfc8 17…d5 is a typical plan in this kind of positions, but right now it’s a mistake 18.e5 Q:e5? 19.Bf4. [17…h6 18.Bxh6! (18.Bh4 Nh7 blocking white’s attack for a moment.) 18…gxh6 19.Qxh6 Nh7 20.g5 Bxg521.Rhg1 White’s initiative is very dangerous.]

18.Ba4 Qd8 Black is treatening with 19…N:e4. White bishop on a4 kills all active plans of black on the queenside and it’s time to start an attack with 19 Be3, 20 g5, etc.

19.Qh2 h6 20.Bh4 Nh7 21.Nb5 White’s attack on the kingside had slowed down and they focus on the weakness of the d6 pawn.

21…d5 22.Bxe7 Qxe7 23.Nd6 Rd8 24.e5This knight is very strong and soon white will start pushing the pawns on the kingside.

24…Ng5 25.Qf2 Rxd6 This is pretty much forced.

26.exd6 Qxd6 27.f4?! This allows the black knight to the center, from where it controls several important squares. It can jump to c5 for example.

27…Ne4 28.Qe3 Rd8 With the idea of d4 and Nc3+ in some variations.
