Nbd2 {I prefer this to 4.Bd2.} 4... O-O 5. e3 b6 6. Bd3 Bb7 7. O-O d5 8. a3 Bxd2 9. Bxd2 { White has the better game because of the two bishops.} 9... Nbd7 10. cxd5 Bxd5 {10...exd5 11.b4 Holds no prospects for Black.} 11. b4 c5 12. Rc1 { 12.dxc5 bxc5 13.Bc3 Ne4 14.Bb2 was also possible.} 12... cxd4 {Black considers that his active pieces and the hole at c4 give him good chances. However, this is a mistaken evaluation, as White's two bishops and Black's hole on c6 gives White the initiative.} 13. Nxd4 Ne5 14. Ba6 {White leaves no doubt to his control of the c-file by taking away the c8 square from the Black rook.} 14... Ne4 15. Be1 {It is important for White to retain the two bishops.} 15... Qg5 { Black is trying to solve his problems in a tactical way. 15...Nd6 16.Qe2 Nf5 17.Bc3 is better for White because of his two bishops and control of the c- file.} 16. f4 Qg6 17. fxe5 Nc5 {Threatening mate on g2.} 18. Bg3 Nxa6 19. Nf5 Rae8 { 19...exf5 20.Qxd5 when White's bishop is much stronger than the Black knight.} 20. Nd6 Re7 21. Rf4 {A strong move as the rook increases the pressure on the f-file and threatens the Black king position.} 21... h5 22. e4 Ba8 23.

Rcf3 { Tripling on the f-file.} 26... f5 27. exf6 {I spent more than 30 minutes calculating the consequences. It was clear that the complications were in favor of the more active White pieces, but I was seeking the simplest way to victory.} 27... Rxd6 { 27...e5 28.Qc4+ Kh7 29.fxg7 exf4 30.Nf5 is also winning for White.} 28. f7+ Kh7 29. Be7 e5 30. Bxf8 exf4 31. Bxd6 Qxd6 32. Qd3 {White's passed f-pawn combined with Black's ineffective minor pieces give me a winning position.} 32... Qe7 33. Qc4 {33.Qd7 Qxd7 is also winning for White.} 33... Kh6 34. Rxf4 {This move allows unnecessary complications. 34.f8Q Qxf8 35.Qxc7 g5 36.Rd3 was the simplest path to victory.} 34... Ne6 35. Qc8 Qd6 36. Qh8+ Kg6 37. f8=N+ Nxf8 38. Qxf8 Qd1+ 39. Kf2 Qd2+ 40.
