The White King leaves the diagonal because Black’s P-B4 would interfere with the combination by which White intends to annihilate Black’s game in a few moves.
33. … K-K1 34. QR-KR1 B-Kt2 35. P-K5!!
A beautiful final stroke.
35. … QPxP 36. Kt-K4!! Kt-Q4 37. Kt(K6)-B5 B-B1
Black dares not move the Rook on account of KtxB and Kt-Q6ch.
38. KtxR BxKt 39. R-R7ch R-B1 40. R-R1 K-Q1 41. R-R8ch B-B1 42. Kt-B5 Resigns
Mate in two is threatened. Black’s only move is Kt-K2, after which he is helpless, and White can capture the pawns one by one at his leisure (R-B7, etc.). In this game, so beautifully engineered by White, we have a further example of Lasker’s remarkable grasp of position.
