Game 253, Mason, James–Pollock, William Henry Kraus, played May 8, 1889, from Wilhelm Steinitz, The Book of the Sixth American Chess Congress (1891), printed pages 318–319.

1. 9.Bg5 The pinning is useless and even disadvantageous under the circumstances that Black's KB is still in communication with the K side and White is liable to be driven back and cut off from his Q wing, as happens. QKt—Q2 was better.
2. 9…dxe4 P—KB3 was preferable now that White could have been compelled either to exchange or to fall back on the K side at R4.
3. 13.Bh4 He would have done better to retreat B—Q2.
4. 14.Bc2 Here is an instance to show that B—B2 is generally preferable in this form of opening on the 7th move.
5. 15.a3 Ingenious, as Black obviously dare not capture either Pawn without subjecting himself to the loss of a piece by the reply P—QKt4.
6. 17.h3 White fails to see through the adverse highly ingenious scheme. Kt—K3, with the view of Castling, was his only good play.
7. 19…Nc4 Ingenious and powerful. He threatens Kt x QKtP.
8. 20.Nd4 There was hardly anything better, bad as this is.
9. 25…Qe6 A regular gem of a game on Mr. Pollock's part. The termination is charming. See diagram.
10. 26.Bb1 If 26 Q x P, 26 Kt x QBP disch., followed by R—Q8 mate; and, of course, if 26 B x Q, 26 P queens ch., and mates next move.
