Notes by H. N. Pili.sbury.

1. 5.Nxc6 Although this line of play has been adopted by Lasker himself with considerable success, it is probably premature, owing to the strengthening of Black's centre Pawns. 5. B to K 3 is more usual and more correct.
2. 5…bxc6 In an exhibition game, played in New York, Lasker, as second player, re-took here with the Queen's Pawn, allowing the exchange of Queens, and relied upon his end game ability to outplay his opponent, and was successful. It is not, however, as good as the text.
3. 13.exf5 This still more strengthens Black's already formidable centre. Probably best now was: 13. P to B 3, P to Q 4; 14. P x Q P, B P x P; 15. B to Kt 3, B to Q R 3; 16. K R to K sq, retaining a pressure on the centre Pawns.
4. 14.Bd4 Premature at least. 14. P to B 4, P to Q 4; 15. B to K 2, threatening R to B 3 and Kt 3, was far superior.
5. 33…Qxf4 Black has managed his centre attack in capital style, and obtained a theoretical winning position. White is unable to stir, and although the game lasts for some time, the issue can hardly be doubtful.
6. 42.h3 This hastens the end, as Black, after judiciously retreating the King to avoid danger of perpetual check arising from Q to Q 3, &c., is enabled to put his Queen at K Kt 6, and then the game is over.
7. 50.Qe4 An ingenious attempt to draw by perpetual check, which would succeed if Black took the Rook.
8. 51…Kh6 For if R to K sq, Black wins by either R x P, ch, Q to B 7, ch, &c., or by the simpler P to K 7.
