Game No. 35, printed pages 44–45, in Wilhelm Steinitz, The Book of the Sixth American Chess Congress (1891). The printed playing date is March 28th. The note to White’s tenth move literally introduces its alternative with “10...QB—KB4” and later gives 11 R—K2, which is illegal after the printed 10 P—KR3; the source wording is retained. The printed title “International Chess Instructor” is also retained.

1. 7.Bd3 7 Q—Q4, 7 Q—K2; 8 P—B3, 8 P—Q4; 9 B—KKt5 brings about a position of the Scotch Gambit which is demonstrated in the “International Chess Instructor,” in favor of White.
2. 8.e5 Wrong on principle, as it allows Black a strong majority of Pawns on the Q side. 8 P x P, 8 P x P; 9 B—QKt5 ch., as played by Señor Golmayo against Captain Mackenzie, is the right play.
3. 10.h3 The attack against the adverse King which he aims at by giving up the KP in exchange for Black's KRP is worthless and only damages additionally his position, on account of the counter-attack which the opponent obtains on the open K file with his Rooks. Black also gains the combination of two Bishops against Bishop and Knight, the latter being besides badly posted for any purpose. Much better was 10...QB—KB4; 11 R—K sq., 11 R—K sq., and if 10...KB—QB4; 11 R—K2, or if 10...P—Q5; 11 P—QR3, 11 B—R4; 12 P—QKt4, etc.
4. 17…Bxc3 Though the parties remain with Bishops of opposite colors, Black obtains a very strong attack, which places great difficulties in the way of the defence.
5. 20.Be3 Overlooking a beautifully-conceived and finely worked-out combination. 20 Q x RP, and if 20...B x RP; 21 B—B4 would have given good prospects of parrying the attack.
6. 21…R8xe3 This and the foregoing move of Black are played in most admirable style, and leave no hope for the opponent. See diagram.
7. 22.Rce1 Of course, if 22 P x R, 22 Q x P; 23 R—B2, 23 Q—Kt6 ch., and wins.
