Game 74 in Wilhelm Steinitz’s The Book of the Sixth American Chess Congress (1891), printed page 99.

1. 10…a6 A ruinous loss of time. 10...Kt—K sq., as played by Harrwitz against Morphy in this position, is by far better.
2. 17.Nd5 White's superior development now decides the game rapidly.
3. 18…Kh7 If 18...BxKt; 19 RxB, 19 KR—K sq.; 20 RxQBP, 20 R—K7; 21 R—Q6, 21 BxKBP; 22 QRxP, 22 R—KB sq.; 23 P—KR4, with a Pawn ahead and a fine game.
4. 20.Re4 A fine move that at least gains a Pawn, with a winning position.
5. 20…h5 His best reply was B—Q3, but even then the game could not have been saved.
6. 22.Rg4 Black is neatly caught in a mating position, from which there is no escape.
