Game No. 293 in William Steinitz’s The Book of the Sixth American Chess Congress (1891), printed page 361.

1. 13.f5 White has obtained the superior position, but the blocking tactics were hardly as suitable to his attack as reserving the option of opening the KB file.
2. 33.f6 He has conducted his attack skilfully against a very clever defence up to a manifest superiority for the ending, which he could have now obtained by P—QB5 instead of the seductive but in reality weak move in the text.
3. 36…Ne4 Intending, if White capture the Pawn, to answer Kt—Kt4, threatening Kt—B6 ch. as well as Kt x RP ch. But, obviously, Kt—R3 had the same effect and was by far more safe, for we believe that White could have won subsequently after the move in the text.
4. 42.Kf4 Failing to grasp a fine winning opportunity by 42 K—K3, 42 Kt—B5 ch. (or 42...Kt—B8 ch.; 43 K—K2, and wins. Or if 42...Kt—K5; 43 K—B4, and should win); 43 K—Q4, 43 Kt x B; 44 K x Kt, 44 P x P; 45 K—B4, and it will be found on examination that after Pawns are cleared White remains with the KRP ahead and reaches with his King the square at KKt7 before Black’s King can come further than to K sq. White’s Pawn cannot, therefore, be stopped from queening.
