Game No. 155 in Steinitz's The Book of the Sixth American Chess Congress (1891), printed pages 200–201 (PDF pages 252–253); headed "Played in the first round, March 29th." Variation (b) retains the printed numbering, which starts with 7 although the line arises at White's sixth move.

1. 3…Nc6 Not advisable in this opening, for in the large majority of its forms it is of the greatest importance for Black to advance P—QB4 as early as possible, and this Pawn is now blocked.
2. 6.e5 The play on both sides has been irregular, but it might have been turned into an old variation, favorable to the first player, at this point by 7 P x P, 7 P x P; 8 0-0, and if 8. . .QB— Kt5; 9 Kt— K2, 9BxKt; 10 PxB, and White has the better game with his two Bishops and the prospect of an attack on the K side after removing K— B sq.
3. 8…h6 Not good. As will be seen it furnishes very soon a mark for the hostile attack on that wing.
4. 13.f4 Formidable as this looks and actually turns out, we would have much preferred dissolving the doubled Pawn on the Q side by 13 P—QB4, for if 13...PxP; White could either obtain the better position by 14 KtxP, or he might win the exchange by Q—K4.
5. 15…f5 Whereas now Black could obtain the superior position on the Q side by 15...P—B5; with no harm to fear for his King, for if 16 P—B5, 16 PxP; 17 QxP, 17 P—B3; 18 B—K2, 18 PxP; 19 PxP, 19 QxP, threatening QxR with a Pawn ahead and the better game.
6. 25.g5 White's attack is conducted with relentless power.
7. 27…Rf5 27...K—B sq. afforded no more relief on account of 28 BxR ch., 28 KxR; 29 P—Kt6 ch., 29 K—B sq.; 30 R—B3 ch., 30 Kt—B3; 31 Q—R8 ch., 31 B—K3; 32 QxP ch., and wins a piece.
8. 31…Kf6 Equally fatal was 31...KxP; 32 Q—R5 ch., 32 K—B3; 33 R (R3)—Kt3, and mates in a few moves.
