Game 255, Showalter, Jackson Whipps–Mason, James, played April 19, 1889, from Wilhelm Steinitz, The Book of the Sixth American Chess Congress (1891), printed pages 320–321. Note (c) retains the source’s printed reference to White’s Queen.

1. 3.Bd3 Rarely adopted and not commendable.
2. 3…c5 3...P x P; 4 B x P, 4 KKt—B3 gives Black a good game at once.
3. 4…exd5 If 4...Q x P, Professor Berger recommends 5 QKt—B3, 5 Q x QP (of course if 5...Q x KtP, White's Queen is lost by the answer 6 B—K4); 6 Kt—B3, with a strong attack.
4. 11.Qd2 Hardly a good plan in this position.
5. 15.Be5 Dropping into a trap, after which the opponent has an easy task to win. B—Kt3 was his right play.
6. 15…Nxf3 Fine play. Obviously White dare not take the Knight on account of the crushing rejoinder Q—Kt5 mate.
7. 47…Rh2+ Direct to the point.
