Notes by S. Tinsley.

1. 11…Nxd4 With slight transpositions we arrive here at precisely the same position and by the same moves as those made in the memorable games by Tarrasch v. Zukertort, 1887, and Gunsberg, 1890, in Frankfort and Manchester respectively. If now 11. Q to Q 2; 12. Kt x B and wins a Piece and the game, for whether Q or P takes the Kt, R x Kt, wins. Kt X K P is also out of the question, as White replies P to B 3.
2. 12…c6 A bolder course is P to Q B 4, but the text move strengthens Black's Pawn position.
3. 14.Nc3 Attempts to win the Kt by P to K R 4 would with an undeveloped Queen's side probably prove dangerous, but it is noticeable that P to K R 4 is possible at this stage.
4. 20…Qh4 The game suddenly reaches a critical point. Except for the presence of Black's Queen White might safely dispose of the strongly posted Knight. But 21. R x Kt, P x R; 22. Q x P, P to K R 4, would break up White's game on the King's side completely.
5. 22.Qg3 The consequences are evidently foreseen. They give Black a momentary advantage.
6. 26.axb3 And Black is a Pawn to the good in an end game. It will be seen however that White's turn is yet to come, and that he must speedily regain lost material.
7. 26…Bb7 Not B to Q 2, because of Kt to Kt 6, &c., regaining at least a Pawn.
8. 30.Kg5 We assume that White, having established his position, and being able pro tern, to keep Black confined closely, is playing for a mating position with his Rooks. Supposing, for instance, Black plays here P X Kt P, then P to B 6, followed soon by R to R 2, &c.
9. 39…Rc8 Another critical point of a very interesting game is here reached. 64 Black scarcely rises to the occasion. He might as well have gone on with P to Q R 4, or perhaps better 39. P to Kt 4, ch; 40. K x P (best), B X Kt; 41. R X B, R X P, ch; 42. K to B 4, R to K 3; 43. K to Kt 5, R to K 4, ch, and would apparently either draw or win.
10. 42.Ke3 The charming audacity of this bold bid for a win is very noticeable. It is probably safe to say that there is no other way to win and that this is the only chance left.
11. 44.Nc5 Necessary to prevent Black winning by giving up a Piece by R to Q 6, ch, &c. later; also to capture the Bishop presently, and furthermore to guard the outlet of the Black King at his Q 2. See his 46th move. R to Q Kt 6 is also now guarded against.
12. 56.Rh1 I have found this game, and especially the ending, exceptionally difficult. One gains the impression gradually as it proceeds that Black should have won, but where is not easy to detect in a brief space of time. Of its absorbing interest after about move 26 there can be no question. Those addicted to analyses will here find a rare opportunity.
