Game 17 in the book: E. Znosko-Borovsky–Alekhine, Masters' Quadrangular Tournament at St. Petersburg, 1913. A Ruy Lopez annotated by Alekhine, who plays Black and wins.
5…Bg45. ....B—Q 2 is better. The variation in the text, favoured by Marshall, is not favourable to Black should White, as in the game Réti—Spielmann, Berlin, 1920, adopt the continuation 6. P—Q 5, P—Q Kt 4; 7. P x Kt, P x B; 8. P—B 4!
6.Bxc6+White also obtains a good game by this move, but allows Black some counter chances.
8.Qe2It is clear that after exchange of Queens Black would protect his K P by 8. ....R x Q, threatening mate if White plays 9. Kt x P.
11…O-OBlack could equally play 11. ....P—B 3 in order to withdraw his Bishop to B 2 in case of need. But he considered that White would not find the time necessary to increase his pressure on the King's side on account of Black's counter-attack on the opposite wing, and in the centre.
13.h4If 13. Kt—R 4, Kt—Q 4!; 14. Kt x B, Kt x B; 15. Q x Kt, B P x Kt, with good prospects.
15…Qb8The Black Queen enters into the game very effectively through this outlet.
16…Qb4Stronger than 17. ....Q—B 6, whereupon White would obtain an equivalent in position sufficient for the Pawn sacrificed, by 18. K—B 2!, Q x B P; 19. K R—Q B 1, Q—Kt 7; 20. Kt—B 4!, Q x Q ch; 21. K x Q, etc.
18.Kf2After 18 Castles (K R) the ensuing reply, 18. ....B—B 4, would be still stronger.
22…Qc3Undoubling the Q B P by force, and in this way removing the only weakness in his position.
23.Rxd6If 23. Kt—B 1, Black would reply simply 23. ....P—R 4, and White could only defer the exchange of Rooks, which must be made sooner or later.
24…d5The most energetic. In exchange for the Q R P Black obtains a strong passed Pawn in the centre and besides, White's Q R P is a most noticeable object of attack.
26.Nef5As this Kt can no longer be assisted by the other pieces, its inroad on B 5 loses much of its efficacy.
29.Qd329. Q—Q 2! would be a little better, with the double threat 30. R—Q B 1 followed by R x P and Kt—K 7 ch, and 30. P—Kt 5. But in this case also Black would secure an advantage in position by 29. ....Q—Q 1!
29…Be6In order to be able to dislodge the Kt, at need, by P—Kt 3, but White prefers to withdraw it himself to maintain the defence of his seriously weakened left wing.
33…c4This temporary Pawn-sacrifice will allow the Black pieces to break through into the hostile camp, and to co-operate in a direct attack against White's King, an attack which will become irresistible thanks to the passed Pawn, which fixes the White pieces on the other wing.
36.Kg3After 36. K—Kt 2, B x B P Black would be threatening to capture the Knight with check.
41.Nd1Else Black would win easily with his passed Pawn.
42…g5+In conjunction with the following move this is the shortest road to victory.
43…h5This Pawn now shares in the attack and settles the result outright. White is helpless against the threat: 44. ....Q—R 8 ch; 45. K—Kt 3, P—R 5 ch; 46. K—B 2, Q—R 7 ch. On the other hand 43. ....P x P would not have been so strong, for White could have still defended himself by 44. Q—K 2!, K—Kt 2; 45. K—R 3!
