Game No. 153 in the book (round 17): a Ruy Lopez won by Emanuel Lasker (White) against Erich Cohn, annotated by Lasker.

1. 12.Rae1 If 12) P - B 4, P - K B 4; 13) Q R - K 1, P x P; 14) Kt x P, Q - R 5; 15) P - K R 3, Kt - B 3 as given in the notes to the game Bernstein-Lasker.
2. 18…f5 Here he should play P - K B 3; he might then later on perhaps open the centre by P - Q 4, but on the whole, he should keep on the defensive.
3. 19.e5 By this reply Black's Pawn at K B 4 becomes a disagreeable blocking piece.
4. 19…d5 By this he creates still another obstruction and establishes beyond any doubt the superiority of the Knight over the Bishop. He ought to play 19) .... Q R - K 1, and reply to 20) P - K Kt 4?, B - B 1. White would probably have secured the possession of the King's file by 20) R - K 2, and would have had slightly the superior position, but not so decisively as in the actual game.
5. 21.Qd4 Black's Queen's Bishop's Pawns now become fixed and are likewise doomed to play the miserable part of blocking pieces.
6. 26…Rxc5 Desperation, to avoid being slowly strangled.
7. 28.Rab1 Immediately decisive, as in reply to R x P, White plays 29) R - Kt 7, R - B 5; 30) Q - R 7.
