Game No. 164 in the book (round 18): a Queen's Gambit Declined won by Akiba Rubinstein (White) against Georg Salwe, annotated by Lasker.

1. 6.e3 P - K 4 is the logical move, as White has the superior position in the centre of the board. Any danger to the K P does not exist; for instance: 6) .... P - Q R 3; 7) B x P, P - Q Kt 4; 8) B - Q 3, B - Kt 2; 9) P - Q R 3 or Q - K 2.
2. 9.a4 An ingenious attempt to institute a lasting attack by freeing the square Q B 4 for his pieces, exposing Black's Kt P to attack, and exerting a pressure on the square Q B 5.
3. 10…gxf6 If 10) .... B x B; 11) Kt - K 4, Kt - Q 2; 12) R - B 1, B - K 2; 13) Q - B 2, R - B 1; 14) Kt - B 5 Black would be badly off. By retaking with the Pawn he changes the aspect of the game; e. g.: 11) Kt - K 4, Kt - Q 2; 12) R - B 1, P - K B 4; 13) Kt - B 5, Kt x Kt; 14) P x Kt, B - Q 4. Now the Bishop can no more be driven away from Q 4 by P - K 4; that is the essential difference as against the continuation 10) .... B x B.
4. 12…c5 Up to here Black has manoeuvred very well; but now he ought to render White's next move more difficult. The attack on Q B 2 was easily parried by B - Q 3; therefore he should let this Pawn take care of itself. Better was P - K B 4; then, if 13) P - K 4, P x P; 14) B x P, B x B; 15) Q x B, O - O, and Black, by such moves as Kt - B 3, B - Q 3, and K - R 1, would succeed in establishing a safe and at the same time aggressive position.
5. 18…cxd4 He could not consolidate his Pawns by P - Q R 4. There was nothing more important to do, and this exchange of Pawns might well have waited.
6. 20…Qe4 P - Q R 4 was still indicated, to secure the position of the Knight at Kt 3. The Queen's move only drives the Knight to a better square and exposes the Queen to attacks.
7. 23…Kh8 Black's play is most inconsistent. If he intended, by this, to initiate an attack on the open K Kt file (which, however, would have no prospects), why did he not play R - K Kt 1 afterwards? If, however, he intended an advance in the centre, why not Kt - B 5, threatening a good many things?
8. 30…e5 It was careless to allow the Knight the square B 5. Kt - K 2 would have led to the exchange of the Q Kt P for the Q B P. Perhaps Black was here pressed for time.
9. 32…Rxc6 A most careless move, which certainly cannot be explained by time pressure, as the critical moment of the 30th move was past. After 32) .... Kt - K 2 it was doubtful whether White could win: at all events, winning would have been a very difficult matter.
