Game 27, printed pages 36–37, from William Steinitz’s The Book of the Sixth American Chess Congress (1891).

1. 5.a3 With the view of preserving the KB against an exchange by QKt—Q4, but we do not think this is worth the time lost.
2. 7…axb6 His open QR file and the prospect of an attack on the Q centre neutralize the adverse two Bishops.
3. 9.f4 We prefer Kt—K2, followed by O—O, in order to reserve the option of advancing P—Q4 or P—KB4, according to circumstances. He creates thus early a hole at K3 that afterward causes him trouble.
4. 19.Bg3 His best plan was now to retreat B—KB2, which would have equalized the game.
5. 19…Nge3 An error of which the opponent very cleverly takes advantage. By playing the other Knight to the same square he could have at least won a Pawn, with an excellent position.
6. 21.Qc1 This fine manoeuvre secures fully the material temporarily given up, with an irresistible attack.
7. 23…Qd8 All this is forced, and he cannot avoid the disaster which his opponent prepares on the next move.
8. 24.Nxg7 This powerful stroke disorganizes the adverse position.
9. 27…Qg6 Probably under pressure of the time limit, and having a hopeless game, Black hastily left himself open to mate at once; but there was nothing to be done. After 27...Q—R2 (the only move); 28 Q—Kt5 ch., 28 Q—Kt3; 29 Q—R4, 29 Q—R2; 30 R—B4, 30 B—Q2; 31 Q—Kt3 ch., 31 Q—Kt3; 32 RxR, 32 RxR; 33 R—R4, 33 R—K8 ch.; 34 K—B2 forces mate in a few more moves.
