This is one of those famous positions in chess history. Dr. Emanuel Lasker, who had held the world throne for 27 years until 1921, has just played 24…Qb5, which wins in every variation except one—the one his opponent Carlos Torre found.

Solution:

Here’s the entire game, Torre Repetto,Carlos - Lasker,Emanuel Moscow, 1925. It is also a wonderful lesson on the “windmill” theme. Both beginners and more experienced players should know this:

1.d4 Nf6 2.Nf3 e6 3.Bg5 c5 4.e3 cxd4 5.exd4 Be7 6.Nbd2 d6 7.c3 Nbd7 8.Bd3 b6 9.Nc4 Bb7 10.Qe2 Qc7 11.0–0 0–0 12.Rfe1 Rfe8 13.Rad1 Nf8 14.Bc1 Nd5 15.Ng5 b5 16.Na3 b4 17.cxb4 Nxb4 18.Qh5 Bxg5 19.Bxg5 Nxd3 20.Rxd3 Qa5 21.b4 Qf5 22.Rg3 h6 23.Nc4 Qd5 24.Ne3 Qb5 (See Diagram) 25.Bf6 Qxh5 26.Rxg7+ Kh8 27.Rxf7+ Kg8 28.Rg7+ Kh8 29.Rxb7+ Kg8 30.Rg7+ Kh8 31.Rg5+ Kh7 32.Rxh5 Kg6 33.Rh3 Kxf6 34.Rxh6+ Kg5 35.Rh3 Reb8 36.Rg3+ Kf6 37.Rf3+ Kg6 38.a3 a5 39.bxa5 Rxa5 40.Nc4 Rd5 41.Rf4 Nd7 42.Rxe6+ Kg5 43.g3 Black Resigns. Lasker could have resigned on move 33 as he was going into a lost endgame three pawns down, but sometimes a certain momentum takes over, and, here, a little bit of shell shock as well.
