Game 231, Mason, James–Baird, John Washington, played May 17, 1889, from Wilhelm Steinitz, The Book of the Sixth American Chess Congress (1891), printed pages 296–297.

1. 5…Bb6 We prefer B x B, followed by Kt—R4, and exchanging the other Bishop.
2. 13…Bxe3 13...Kt x B; 14 RP x Kt, 14 B—Q sq., was now much better play.
3. 18…Qg5 P—KB4 would have equalized positions.
4. 26.Rfg1 White has energetically taken advantage of the time lost by the adversary to form a strong K side attack.
5. 28…Rfd8 In view of the coming onslaught of the adverse Pawns, which were sure to give him an opportunity of opening the KB file, this Rook stood better where it was, and the QR should have been employed for occupying the Q file here, as well as previously on the 22d move.
6. 31.gxf6 Brilliant, profound and absolutely decisive, as will show itself within a few moves.
