Game 246, Mason, James–Judd, Max, played May 11, 1889, from Wilhelm Steinitz, The Book of the Sixth American Chess Congress (1891), printed pages 312–313.

1. 9.d6+ He ought to have stuck to the Pawn which formed his only compensation for the adverse superior development. Nor can we see any danger for White after 9 P x P, 9 Kt—K5 (or 9...QB x P; 10 Kt—K2, 10 KR—Q sq.; 11 Q—B sq., and should maintain his Pawn); 10 Q—Q5, 10 B x P ch.; 11 K—B sq., 11 Kt—B3 (if 11...Kt x Kt; 12 Q—KKt5 ch., with an excellent attack); 12 Q—Q2, 12 B—Kt3; 13 P x P, etc.
2. 10.Qd2 This trap compromises his game. Kt—K2 was the correct play.
3. 13…Nxc3 Black has beautifully parried the opponent's attack and has assumed a strong offensive which wins a Pawn at least.
4. 14.bxc3 If 14 Q x R, 14 Kt—Q4 disch.; 15 P—QB3, 15 B—Q3; 16 Q—R8, 16 Kt—Kt3, and wins.
5. 19…Ke8 K—B sq. was preferable.
6. 47.g3 Probably an oversight, but he could not hold out for long either after 47 R—R3, 47 P—R5.
7. 50…Bf3 Quite decisive, for he threatens K—Kt5, and if White answer R—R4, the reply R—K5 forces the exchange of Rooks. Black's play throughout this game is highly commendable.
