Bg2 Nf6 7. O-O Be7 8. dxc5 Bxc5 9. Nbd2 d4 {Usually in this variation, what
with the White Kt on c3, this move wins a tempo which makes all the difference
and gives Black the superior position. Here, however, the move loses an
important tempo which should have better been used for development.} 10. Nb3
Bb6 11. Qd3 {! Lasker now refutes the ill- considered pawn-push very shrewdly.
Since his pawn would get lost by Rd1, Black must go in for an unfavourable
exchange.} Be6 12. Rd1 Bxb3 13. Qxb3 {Here, as will soon be evident, the White
Queen is excellently placed.} Qe7 {So as to dodge the attack of the e-pawn.
Black's position now looks reasonably good, but he is a tempo behind in
develop men and that makes all the difference.} 14. Bd2 O-O 15. a4 {A very
subtle move, the force of which Black fails to recognise. The pawn is to push
on to a6 so as to loosen the position of the Black pieces, particularly the
Queen Knight. Naturally Black must not take the e-pawn since 16 Re1 Qa6 17 Bf1
would cost him the Queen.} Ne4 {It would have been best to stop the further
advance of the pawn by either ...Bc5 or a6 but White would have had the better
game in any case; Black's position, though, may still have been tenable,
whereas now it breaks down very quickly.} 16. Be1 Rad8 {? Rac8!} 17. a5 Bc5 18.
a6 bxa6 {After ...b6 White would still maintain his advantage by 19 Qa4
followed by 20 b4.} 19. Rac1 Rc8 20. Nh4 {Forcing material gain, since White
threatens to win the Knight or the Bishop.} Bb6 21. Nf5 Qe5 22. Bxe4 Qxe4 23.
Nd6 Qxe2 24. Nxc8 Rxc8 {For the loss of the exchange Black, at any rate, has a
strong passed pawn which might enable him to save the game so long as he can
avoid the exchange of rooks.} 25. Qd5 Qe6 26. Qf3 {At this juncture the
exchange of queens would not be quite favourable enough for White.} h6 27. Bd2
Ne5 28. Rxc8+ Qxc8 29. Qe4 Nd7 30. Rc1 Qf8 31. Bxh6 {!} Nc5 {If ...gxh6 White
would regain the piece by 32 Qg4+.} 32. Qg4 f5 33. Qg6 Qf7 34. Qxf7+ Kxf7 35.
Bg5 Nd3 36. Rb1 {Not, of course, Rc2 since Black would win a piece by ...Ne1
followed by ...Nf3+.} Ke6 37. b3 Kd5 38. f3 a5 39. h4 Nc5 40. h5 d3 {Black is
hopelessly lost since there is no way to stop White from getting a passed Pawn
on the King's-wing.} 41. Kf1 a4 42. bxa4 Nxa4 43. Bf6 {!} Ke6 44. Bxg7 Kf7 45.
Be5 Nc5 46. Rd1 {Obviously the d-pawn will get lost. A beautifully played game,
but then almost all of Lasker's games in this Tournament are worthy of a World
Champion.} 1-0
