Game 48 in the book: Alekhine–M. Feldt, played in a blindfold exhibition at the military hospital in Tarnopol, September 1916. A French Defence annotated by Alekhine, who plays White and finishes with a celebrated queen sacrifice.
5.Ne4More usual is 5. Kt—B 3, but the text-move, which aims at preventing 5. ....P—Q B 4, is equally to be recommended.
5…f5A weakening of the centre which will ultimately prove fatal. The best move was 5. ....Kt—Q 2, with P—Q B 4 to follow eventually.
6.Ng5A good move. White intends to play his Knight to K 5, thereby taking immediate advantage of the weakness created by his opponent's previous move.
7…c6A lost tempo. Better is 7. ....Castles.
11…Re8If here 11. ....Kt—Q 2, then 12. P—B 4, Kt (Q 4)—B 3; 13. Kt—Kt 5, etc.
14…c5Here 14. ....Kt—B 1 was essential. The text-move allows of a brilliant finish.
15.Nf7This threatens 16. Q x P, followed by the smothered mate, if the Black Queen moves.
16.Qxe6+The point of the combination.
16…Kg6Or if 16. ....K x Q; 17. Kt—Kt 5, mate. Or if 16. ....K—B 1; 17. Kt—Kt 5, and White wins.
17.g4White announced mate in two by 17. P—K Kt 4!, B—K 5; 18. Kt—R 4, mate.
