Nxd4 Nf6 5. Nc3 d6 6. Be2 Be7 7. O-O O-O 8. Be3 Nc6 {Perhaps this commits the knight too early. Another idea is to gain space on the queenside with pawn a6 followed by pawn b5; when the Black knight would keep the option of going to c5 attacking White's e-pawn via d7.} 9. f4 Qc7 10. Qe1 { White prepares an attack by lifting the queen over to the kingside.} 10... Nxd4 11. Bxd4 e5 12. Be3 Be6 {A mistake which weakens the d5 square since Black's light squared bishop will be unable to stay on e6. 12...exf4 With the idea of clearing an outpost on e5 for the Black knight. 13.Rxf4 Be6 14.Bd4 Nd7 15.Qg3 Ne5 With chances for both sides.} 13. f5 {White wants to drive the bishop away so that his knight can gain the outpost at d5.} 13... Bc4 {13...Bd7 Black should admit that he needs his light squared bishop to cover the d5 square. For example 14.g4 Bc6 15.Bf3 d5 16.exd5 e4 17.Nxe4 Nxd5 18.Bd4 when White's pawn advantage is somewhat hampered by his exposed king.} 14. Bxc4 Qxc4 15. Bg5 {White wastes no time in removing Black's last protector of the d5 square.} 15... Rfe8 16. Bxf6 Bxf6 17. Nd5 {White has a big advantage due to his active knight which is planted on the d5 square.} 17... Bd8 { 17...Qxc2 18.Rf2 Qc5 19.Rc1 Qd4 20.Nc7 Forks the Black rooks.} 18. c3 b5 19. b3 Qc5+ 20. Kh1 Rc8 21. Rf3 {White's outposted knight on d5 cramps the Black pieces which means they will have problems getting over to protect the king.} 21... Kh8 {21...f6 Played to stop White from playing pawn f6 would be met with 22.Rh3 a5 23.Qh4 with an attack on the h-file.} 22. f6 gxf6 { 22...g6 23.Qd2 Rg8 24.Qh6 Bb6 This allows White a forced mate in two.} 23. Qh4 Rg8 24. Nxf6 {The White knight moves from his d5 outpost to join in the winning kingside attack.} 24... Rg7 25. Rg3 Bxf6 {Black finally eliminates the White knight but in so doing creates new problems .} 26. Qxf6 { The pin on Black's g7 rook proves to be fatal.} 26... Rcg8 27. Rd1 d5 28. Rxg7 {Black resigned. 28.Rxg7 Black resigned due to his weak back rank after Rxg7 29.Rxd5 when Rd8+ follows next move.} 1-0
