Notes by H. N. Pillsbury.

1. 6…Be7 A well-known form of the Lopez attack has developed. Many masters, notably Tchigorin, prefer to develop this Bishop at K Kt 2.
2. 9.Bb3 Steinitz and others would prefer B to B 2 at once.
3. 13.O-O Generally the first player in previous games in this opening has preferred to Castle Queen's Rook, and prosecute the attack upon the adverse King by advancing his Pawns; but the Black Pawns would advance upon the Queen's side too rapidly in this position, therefore Dr. Tarrasch abandons this idea.
4. 15.a4 The opened file proves of great service to White later on.
5. 19…Bb6 Inasmuch as the King's Pawn needs more protection soon, Black might have tried here Kt to Q 2, being then prepared to support it by P to K B 3.
6. 21…Rc6 The movement of the Rook only loses time, and leads to the direct loss of a Pawn later on. Moreover, Kt to Q 2 was always correct to prevent the Queen's entrance at B 5.
7. 22.h3 Also loss of time.
8. 25.Ra5 This move might have won a clear Pawn.
9. 25…Ra6 An error: R to Kt 3; 26. Q to B 5, B to Kt 2 would have saved the Pawn.
10. 26.Rca1 Unaccountable, except perhaps on account of time-pressure: 26. R x P, Kt x R; 27. B x Kt, &c., would have won the Pawn clear.
11. 28.c4 Also here Q to B 5 would win a Pawn.
12. 34.Qa1 A tremendous error which loses the exchange; R to R 5 still left White with the superior game.
13. 42…Nd7 White here exceeded his time, and thereupon resigned. Black should win, however, being soon able to enter the 8th row with combined Queen and Rook and form a mating position, from which White could only escape by decisive loss of material.
