Dus Chotimirsky, Fedor Ivanovich VS Lasker, Emanuel 1909.03.08

Annotations

1. 6…Nbd7 The better system was 6) .... P - Q Kt 3, followed by B - Kt 2; or 6) .... P - B 4 at once.
2. 7…c6 Blocking the diagonal of the Q B, and loss of time as against P - B 4.
3. 9…Qa5 Better at once Kt - Kt 3 and Kt(Kt 3) - Q 4. The move actually threatens nothing and defends nothing.
4. 13.Bd3 The Bishop at B sq is now very badly placed; to 13) .... P - Q Kt 3, 14) Kt - K 5 would be a disagreeable reply. 13) B - Q 2 should have been played, although Kt - K 5 and B - R 4 might have followed.
5. 20.Nxd7 White shows splendid judgment of position, by playing for two Bishops; this gives him a lasting superiority.
6. 24.e5 To meet 24) .... Kt - Kt 4 by 25) P - B 6.
7. 32…Ne6 If 32) .... Kt - R 2, then 33) P - K 6.
8. 34…Qg4 A “swindle.” Owing to White's two Bishops and the strong passed Pawn, Black can defend himself only by counter attack.
9. 37.Rd3 The only, but sufficient, defence against R - B 6.
