Bg2 {The Queen's Indian Defense where Black obtains a solid but somewhat passive position.} 5... c5 { This aggressive attempt to take over the center backfires.} 6. dxc5 Bxc5 7. O-O O-O 8. Nc3 {White has the advantage due to his control of the d-file.} 8... d5 {This move cuts down on White's control of the d-file. However, it allows White the opportunity to unmask his light squared bishop with advantage. 8... Nc6 would be a better move although White would still remain with the advantage due to Black's d-pawn standing on the semi-open} 9. Nd4 { 9.Ne5 Qc7 10.Bf4 Nh5 would give Black the advantage of the two bishops.} 9... Bxd4 {9...Nc6 10.Nxc6 Bxc6 11.Bg5 Be7 12.Rc1 would give an advantage to White because of his more active pieces.} 10. Qxd4 {White has gained the two bishops and in an open position like this one this constitutes a big advantage.} 10... Nc6 11. Qh4 dxc4 12. Rd1 {Very well played! White is in no hurry to capture the c-pawn and first takes control of the d-file.} 12... Qc8 {12...Qe7 13.Bg5 h6 14.Bxf6 Qxf6 15.Qxf6 gxf6 16.Rd7 Rab8 17.Rxb7 Rxb7 18.Bxc6 would give White two pieces for the rook and pawn.} 13. Bg5 Nd5 { 13...Nd7 14.Ne4 With the threat of 15.Nd6 would give White a big initiative.} 14. Nxd5 exd5 15. Rxd5 { 15.Bxd5 Na5 would allow Black to exchange of White's light squared bishop.} 15... Nb4 16. Be4 { White's superior development allows him to train his sights on the kingside.} 16... f5 { 16...h6 17.Bxh6 Bxd5 18.Qg5 g6 would allow White a forced mate in two.} 17. Bxf5 {With this move White is able to win Black's queen.} 17... Rxf5 18. Rd8+ Qxd8 19. Bxd8 { White has a material advantage and with Alekhine's technique the game is over.} 19... Rc8 20. Rd1 Rf7 {Stops the White rook from taking the seventh rank.} 21. Qg4 Nd3 {An oversight or is Black giving up?} 22. exd3 Rxd8 23. dxc4 { Perhaps Black missed that White's queen is protecting his rook on d1.} 23... Rdf8 24. f4 Re7 25. Kf2 h6 26. Re1 {When ahead in material you should exchange pieces to make promoting a pawn easier.} 26... Bc8 27. Qf3 Ref7 28. Qd5 { White's queen is pinning the rook on f7.} 28... g5 29. Re7 gxf4 30. gxf4 { Black resigned due to his material deficit.} 1-0
