Game 43 in the book: a Queen's Gambit Declined, one of twenty simultaneous games played at Paris, September 1913, in which Alekhine has White against M. Prat.

1. 3…e6 Tchigorin's Defence is only playable if the Q B is developed at K Kt 5. The text-move which, on the contrary, obstructs this Bishop, can only create difficulties for Black.
2. 4…dxc4 A further renunciation. Black now abandons the centre, and it is not surprising that White, in a few moves, obtains an overpowering position.
3. 11…h6 Opposing the threat 12. P—K 5 followed by 13. Kt—Kt 5, but at the cost of a considerable weakening of the Castled position.
4. 13…Re8 In order to liberate the Queen. A catastrophe at K B 7 is already in the air.
5. 16.Nxf7 This can hardly be termed a sacrifice, as White is in a position to regain the piece with the superior position, but it is rather the initial move of the elegant final combination.
6. 17…Neg8 Here White could have regained his piece by 18. P x Kt, P x P! (if instead 18. ....Kt x P; 19. P x P ch, B x P; 20. R x Kt ch, etc.); 19. P x P ch, K—Kt 2! He quite rightly prefers to aim at the mate.
7. 21.Rde1 The sequel clearly shows the object of this move.
8. 22.Qh5+ Here White announced mate in 10 moves as follows: 22. Q—R 5 ch!, Kt x Q; 23. P x P dbl ch, K—Kt 3; 24. B—B 2 ch, K—Kt 4; 25. R—B 5 ch, K—Kt 3!; 26. B—B 6 dbl ch, K—Kt 4; 27. R—Kt 6 ch, K—R 5; 28. R—K 4 ch, Kt—B 5; 29. R x Kt ch, K—R 4; 30. P—Kt 3!, any; 31. R—R 4 mate.
