Notes by W. Steinitz.

1. 3…dxc4 Since White usually develops the King's Bishop in some manner with the view of Castling on the King's side, Black, by this early capture, deprives himself of the chance of gaining a move.
2. 5…Be7 P to B 4, followed by Kt to B 3, threatening the isolation of the Queen's Pawn, is superior, for the reason alone that Black has not wasted a move with his Bishop in case White exchanges Pawns.
3. 7…b6 Opposed to the principles laid down in the ' Modern Chess Instructor.' The two wing Pawns on either side ought to be kept unmoved as long as possible.
4. 9…c5 The long postponement of this advance, which becomes generally necessary in this opening, makes already a strong difference in favour of White's position.
5. 12.e5 White has formed his battle order faultlessly, and has obtained a great superiority of development and disposition of forces, which might have been more firmly established by B to B 4 at this juncture, while the next move opens a good counter-resource for the adversary.
6. 12…Nfd7 Rather than allow himself to be so closely crowded he should have ventured on a promising investment of a Pawn, which was likely to return a capital game; perhaps thus:—12. ... Kt to Q 4; 13. B x Kt, P x B; 14. Q to B 3, R to Q sq; 15. Kt to B 5, B to B sq; 16. Q Kt x P, Kt to B 3; 17. Q to K 4 (or K to R sq), R x Kt; 18. R x R, Kt to Kt 5; 19. Kt to K 3, Kt x R; 20. Kt x Kt, Q to B 3, and wins.
7. 13…Rd8 His Queen is still more uncomfortably choked up by this move. Kt to Q B 4 gave him more time for shaping his defence and for development. If White answered P to Q Kt 4, then the same Knight to R 3, and afterwards to B 2, would fairly secure the Queen's wing.
8. 14.Nxe6 The sacrifice is not sound, and, moreover, uncalled for, as there was hardly any good answer to 14. Q R to B sq. Black was then a little too late with 14.... Kt to Q B 4, on account of 15. P to Q Kt 4, Kt to R 3; 16. B x Kt, Kt x B (or 16.... B x B; 17. P to Kt 5, followed by Kt to K 4); 17. Kt to K 4, Q to Kt sq (if Q to Q 2; 18. Kt to B 5, &c.); 18. P to Q R 3, with a fine game.
9. 16…Rf8 A fine move, which seems to have been overlooked by White in his sacrificing plan.
10. 17.Qg4 If 17. Kt to Q 5, Q to K sq; 18. Kt to B 7, Q to Kt 3; 19. Q B to Kt 3, Kt to B 4; 20. P to Q R 3, Kt to B 3, with material advantage and a well-balanced position in all directions.
11. 21…Bxd5 Misjudged. 21. ... B to B 4 was the right play. White could not displace the Bishop by 22. P to Q Kt 4 on account of the rejoinder B x Kt, winning a Pawn. Nor was 22. Kt to B 7 of any use, as Black would answer Q to B 3.
12. 23…Qe7 Black seems over-anxious not to allow the adverse Rooks to double on his second file; but this could do no harm, and he ought to have brought out Kt to K 3, which could have been well followed up by Q to Kt 3.
13. 27…g6 Very compromising in many ways. Sooner or later the opponent will force the Bishop's Pawn on, supported by the King's Knight's Pawn, and thus obtain two combined passed Pawns in the centre; whereas if the Pawn were kept at Kt 2, White must have been content with one passed Pawn for a long time. Moreover, if he had now played the clearly much stronger 27.... Q to Q B 2, White could hardly venture on 28. P to B 5, on account of the rejoinder 28.... B to K 2, opening the file for Queen and Rook, and also threatening B to Kt 4.
14. 32…Rf7 Indecision marks Black's defence. The Rook stood much better where he was, and White's King's Pawn should have been once more attacked by 32.... Kt to Q 2, when, after 33. R (Q sq) to K sq, B to Kt 5; 34. P to B 5, P x P; 35. P x P, Q to B 2, Black would gain important time at least, since, in reply to 36. P to K 5, he would check with the Queen at Kt 2, followed by Kt to B 3.
15. 36…gxf5 Only adding another important open file for one of the Rooks without affording the least relief to himself. The game is practically decided for White, though it still requires fine ending play, to which, however, Mr. Lasker is more than equal.
