That way the e4 move would be less powerful (12...♘b4 at once is very interesting and needs analysis.) 13.♘c3 ♕e7 14.♘e4 moving to c5 and opening th b2 Bishop. Once again the c5 square is very important. 14...f5?!

14...♖fd8?!15.♘e5!15...♘xe5 16.dxe5 ♗b4 17.♖d1!! aiming at the d4 square, trying to lift to d4 and attack... 17...a5?!

17...♔h8 need to analyse that one) 18.♘f6 gxf6 19.exf6 ♕f8 20.♖d4 again. 20...♗c3 21.♗xc3 ♘xc3 22.♕h5 ♘d5 23.♕h4±

18...gxf6 19.exf6 ♘xf6 (19...♕f8 20.♖d4 one of the points of Rd1) 20.♗xa8±

15.♘c5 ♗c8 My opponent is playing computer best moves again and again so its very easy to predict what he will play. Not a very wise way to play. 16.♘e1 ♘cb4 17.♗a3 ♖a7 18.f4 This one was a tough decision. The other option was

18.♘f3 ♘c6 19.e4 fxe4 20.♕xe4 ♘db4 (20...a5 21.♘e5 ♗xe5 22.dxe5 b4 23.♗b2±) 21.♘e5 ♘xe5 22.♗xb4 ♘d7 23.♕e2 ♘f6 24.♖e1 ♕f7 25.f4 (25.♘d3 ♘d5 26.♗c5 ♗xc5 27.dxc5 c6 28.♕d2 ♖a8 29.f4±) 25...♘d5 26.♗a5 c6 27.♖ac1 ♕f6 28.♕d1 ♗xc5 29.♖xc5 ♗d7 30.♖e5± And although this is overhelming for white in OTB games, i just had a feeling that it would be hard to win this one, since after taking the pawn back i would definately make exchanges.

18...♘c6 19.♘ed3 ♖d8 20.♗xd5! A very hard decision. Leaving black with the bad bishop but also creating opposite colored bishops in the game 20...exd5 21.♘e5 ♗xe5 22.dxe5 ♕e8 23.♗b2 ♖a8 24.♗d4 stopping the d4 breakthrough (bad or good it doesnt matter) and will gradually build the position). White is playing by himself. 24...♕g6 25.♖c3 b4 26.♖c2 a5 27.♖ac1 h6 I was expecting

27...♘xd4 28.exd4 ♕b6 29.♔g2 this prepares Na4 and after Qd4 (without a check) Nc5 trapping the Queen 29...♖a7 30.♘a4 ♕b8 31.♕h5 ♖f8 32.♕f3 The plan is simple. Re1 (to threaten e5-e6). h4-h5 to provoke h6. Then Nc5 , Qd3, g4... white simply wins.

34.♕f3 ♗e6

34...c6 this is cutting off the Queen from the king side. 35.e6 ♖xe6 36.gxf5 ♖f6 37.fxg6±

34...♕c6 35.♖a1 ♗e6 (35...♗d7 36.♖ga2 fxg4 37.hxg4 ♖f8 38.♖xa5 ♗c8 39.♕g3 ♕e8) 36.♖ga2 ♕b6 37.♘xe6 ♕xe6 38.♖xa5 ♖xa5 39.♖xa5 ♕c6 40.♖c5 ♕a6 41.♔g3 c6 42.♖c1 ♖g7 43.♕e3 ♖a7 44.e6 ♖e7 45.♖e1 ♕a2 46.gxf5

35.♖gc2 c6 36.♘xe6 ♖xe6 37.gxf5 gxf5 38.♕d3± but its not clear cut

34...♖g7

34...♗e6 35.♖gc2 c6 36.♘xe6 ♖xe6 37.gxf5 gxf5 38.♖g1± and white has control of the g file and a clear advantage

35.♕f3 ♕c6

35...♗e6 36.♖gc2 now the bishop is not protected 36...♖a7 37.g5 h5 38.♘xe6 ♕xe6 39.♖c6 ♕d7 40.♖1c5 ♖e7 41.♖f6+⁠−

37.♕g2 ♔h8 38.♘e4! the knight heads to a more useful post 38...♕b6 39.♘f6 ♕xd4 40.♕f3 fxg4 41.hxg4 g5 42.♘h5 a4

42...♖f7 43.♖c6 ♕xe5 44.♕d3!!44...♕e4 45.♕d2!45...♖a6 46.♖e1 ♖xc6 47.♖xe4 dxe4 48.♕d8 ♔h7 49.♕xc8+⁠−

43.♖d1 ♕e4 44.♕xe4 dxe4 its amazing that the engine still shows 0.00!! Rybka 4 is better in this position than Houdini 4 and the latest Stockfish 45.f5 c5 (45...e3 46.♘f6 ♖e7 47.♖d8 ♔g7 48.♖xc8+⁠−) 46.♖xc5I think this variation with a6 Nc6 b5, gives white a very nice and easy play.
