Annotations

1. 3…Nf6 Though Black does not advance P—QR3 on the third move, as in the previous game, the positions become very similar, but the line of play adopted by each of the parties is widely different from the respective treatments of this opening by the players in the first quoted game which occurred eleven years later.
2. 10…Bb7 Generally it is preferable in such a situation to keep the B in communication with both wings and B—Q2 is preferable. The B is here posted with some remote expectation of bringing it to bear against the King's side.
3. 11…d5 Not good, for it leaves a hole at QB4, which weakens all the Pawns on the Q side. P—Kt3 with the object of playing Kt—Kt2 or else P—QB4, followed by P—KB4, was more congenial to the position.
4. 12.Nf5 White also plays for a King's side attack which can be easily guarded against, and he endangers his game when he could have obtained a sure advantage by manoeuvring on the other side Kt—QKt3 with the object of playing Kt—B5 or R5 sooner or later was the proper play.
5. 15…Nxf5 Lowenthal rightly suggests here B—B sq. as much stronger. White had then to guard against the threatened P—KKt3, and his whole attack would have soon been broken. The likely continuation was after 15....B—B sq.; 16 B×Kt, 16 P×B; 17 Q—B3, 17 QB×KKt; 18 Q×B, 18 B×Kt; 19 P×B, 19 R—K4, followed by Q—K2, with much the superior game.
6. 18…a4 Black's game is now inferior. If 18....R—K5; 19 Kt—Kt3, 19 R—B5; 20 Q—QKt3, 20 B—R3; 21 B—R3, 21 P—R5, 21 Q—Q3, and we prefer White's game.
7. 21…Be5 Black gives the opponent an opportunity for a beautiful combination stroke. But his game was anyhow very bad already, for in answer to QR—R sq., which was about his only other alternative, White would have replied Kt—R5 with an irresistible attack.
8. 22.f6 The present key move of his final attack is remarkably fine and effective.
9. 22…Qxf6 If 22....P×P; 23 Kt—B5, 23 Q—B sq.; 24 B×B, 24 P×B; 25 R×P, 25 K—R sq.; 26 Q—Kt3, with a fine attack.
10. 24.Qe2 Overlooking the forcible winning process by 24 R×B, 24 R×R; 25 P—KB4, 25 Q×P; 26 R—KB sq. and wins.
11. 24…Qh8 Black on the other hand does not see that he can save and win the game now by Q—Kt3 followed by P—B3 if B×B.
