Game 258, Mason, James–Taubenhaus, Jean, played May 21, 1889, from Wilhelm Steinitz, The Book of the Sixth American Chess Congress (1891), printed pages 323–324.

1. 3…f5 Very hazardous in an important game against a strong opponent.
2. 4.d4 P—Q3 is, we think, the simplest plan to maintain the advantage, for White has the same position as in the King's Gambit Declined, with a move ahead.
3. 4…fxe4 Black could have made it more difficult for the opponent either by 4...P—Q3 or 4...Kt—KB3 at this juncture. If, however, 4...KP x QP; 5 P—K5 leads to a position similar to the Falkbeer variation in the King's Gambit Declined, with a move ahead for White.
4. 8…Bb4+ Loss of valuable time or of a piece is the consequence of this ill-considered development. QB—KB4 or Kt—K2 were his best defences, but he had already much the worst of the position.
5. 17.Bh3 His best plan was again to retreat B—K2, followed by Kt—B sq.
6. 23.fxg3 Retaking with the Bishop wins with less trouble.
7. 25.c5 If 25 Q—Kt4, 25 Q x B; 26 Q x B, 26 P x Q, winning the QRP, would make a hard fight of it.
8. 27…Ng6 He might have made a more stout resistance after P—QKt4 instead.
9. 36.Qf4+ For after 36...K—K3, follows 37 Q—B5 ch. and Q—B7 ch., winning a Rook.
