Nf3 Bb7 7. Nc3 Nbd7 8. O-O O-O 9. Ne2 c5 10. Ng3 Qc7 11. Ne5 Nxe5 12. Bxe5 {Just compare the relative activity of the bishops! Black is already in serious trouble.} 12... Qc6 13. Qe2 a6 {White has completed development and is ready to attack. The position of the rook at a1 cannot be improved, for the moment. Lasker starts by eliminating one of the few defenders of the Black king. But he doesn't part with the Be5.} 14. Nh5 Nxh5 {White could simply recapture at h5 with a strong attack, but by sacrificing a piece the momentum is greatly increased.} 15. Bxh7+ Kxh7 16. Qxh5+ Kg8 {Now White might like to transfer a rook to the h-file, but this is too slow, because Black is ready to play d5-d4 and threaten mate at g2. Then he could sacrifice some material in return and stay in the game.} 17. Bxg7 {A brilliant move which threatens mate at h8.} 17... Kxg7 18. Qg4+ Kh7 {Now the queen guards g2 and White can threaten the sideways equivalent of a back rank mate.} 19. Rf3 e5 { The only defense. Now the Black queen can come to h6.} 20. Rh3+ Qh6 21. Rxh6+ Kxh6 22. Qd7 { This wins one of the bishops, and the game now is decisively in White's favor.} 22... Bf6 23. Qxb7 Kg7 24. Rf1 Rab8 25. Qd7 Rfd8 26. Qg4+ Kf8 27. fxe5 Bg7 { 27...Bxe5 28.Qh5! f6 29.Qxe5 shows another method of exploiting the pin on the f-file.} 28. e6 Rb7 29. Qg6 { White exploits the pin in the maximally efficient way.} 29... f6 30. Rxf6+ Bxf6 31. Qxf6+ Ke8 32. Qh8+ Ke7 33. Qg7+ { Now the rook at b7 falls, so Black gives up.} 1-0
