Game 248, Mason, James–MacLeod, Nicholas, played April 29, 1889, from Wilhelm Steinitz, The Book of the Sixth American Chess Congress (1891), printed pages 314–315.

1. 10.h3 Usually disadvantageous, as often pointed out, and quite bad here as it costs a Pawn.
2. 10…Nxe4 Very well played.
3. 12.Qxe4 If 12 B x B, 12 Q x B; 13 KR—K sq., 13 P—KB4; 14 Kt—Q2, 14 Q—B2, threatening Q x RP, etc.
4. 15…b5 Much better was 15...P—B3, for if 16 Q x P, 16 Q—Kt3; 17 Q—R3! (if 17 P—QKt3, 17 Q—R4, with a fine attack), 17...Q x BP, etc.
5. 19…c6 Black selects the best move for the defence, as White threatened P—Kt6.
6. 30.Kc1 P x P first was much better.
7. 39…Kd7 K—Q3 was the right play on principle in order to keep the adverse King at a further distance as long as possible.
8. 41…a3 41...P—B5 first was the right play, for if 42 K—K4, 42 K—B3; 43 R—Kt5, 43 P—R6; 44 P x P, 44 R x P, and draws with ease.
9. 44…Rf3 Black has made a splendid fight, especially considering the strength of his opponent, and he had still a draw now by rights of the position, but he allows himself to be caught now by his shrewd opponent. After 44...K—Q sq.; 45 R x P, 45 R—R4 ch.; 46 P—B5, 46 R—R8, Black could prevent loss by subsequent good play.
