7…Nge7Since the contest was finished we have carefully examined the leading variations arising from the defence initiated on Black's previous move 6....Q—B3 and we come to the conclusion that it ought to be favorable for the second player. The line of attack adopted by White in this game is the most dangerous to meet, but we believe that Black by a little amendment of the developing moves can make his game secure and keep the material advantage. The right move at this juncture is 7....Kt—R3 and afterward Kt—K2 instead of Kt—Q sq.
8.d5To the attack adopted by Mr. Tschigorin in the 5th game at this point, viz 8 Q—Kt3, 8 O—O; should be added the following line of play, 9 Kt—R3, 9 P×P (best, for as Mr. Ranken points out in the British Chess Magazine, if 9....P—QR3; 10 B×P ch., 10 R×B; 11 Kt—B4, 11 Q—Kt3; 12 QKt×P, 12 Kt×Kt; 13 Kt×Kt, 13 Q—K3; 14 Kt×R, 14 K×Kt; 15 B×Kt, 15 Q×Q!; 16 P×Q with an excellent game); 10 P×P, 10 Q—Kt3; 11 P—Q5, 11 Kt—Q5; 12 Kt×Kt, 12 Q×B; 13 P—Q6, 13 Kt—Kt3; with the superior game.
12…Qb8The idea on which this is based appears to us still correct, subject to its being prepared in the manner suggested above. As will be seen, in practical play Black succeeded in extricating himself in spite of the large odds against him in consequence of his pieces being imprisoned. But it should be noticed that Black could not allow a hole to be formed at his Q3. If, for instance, 12....P—KB3; 13 P×P, 13 Q×P; 14 Kt—Kt5, 14 P×B (or 14....B—B4; 15 B—K3, etc.); 15 KKt×KP, 15 Q—B4; 16 Kt—Q6 ch., 16 K—B sq.; 17 Q×P, with a winning attack.
15.Nxe5Not as good as Q—Kt4 played by Mr. Tschigorin in a subsequent game.
15…f6Black could now have obtained a great superiority by 15....B—B4; 16 B×P, 16 P—QKt4; 17 Q—Kt3, 17 B×QP; 18 P—KB4, 18 B—B4 ch.; 19 K—R sq., 19 P—Q3; etc.
17.e5Excellent play. The attack which White obtains is quite worth the piece which he gives up.
19…Ne6This seems to have been the only move not so much in order to protect the exchange as to prevent other vehement attacks. If, for instance, 19....Kt—B2; 20 Kt—B7, 20 P×P; 21 Kt×P, 21 Kt×Kt (or 21....B×P; 22 R×B, 22 Kt×R;—if 22....Q×Kt; 23 Q—B4, etc.,—23 Q—B4 ch.; 23 K—Kt sq.; 24 Kt—Q5 and wins); 23 Q—B4 ch., 23 Kt—B2; 24 R—K sq., 24 B—Kt2; 25 R—B7 and wins.
21…Kf7A careless move. He ought to have played K—Kt2.
22.Qh5+For White could now get his Kt into play by 22 Kt—K5 ch., which Black could not venture to capture e. g., 22 Kt—K5 ch., 22 P×Kt; 23 R—Q3, 23 P—KR3 (there is nothing better as White threatens Q—K7 ch. followed by R—Kt3 ch.); 24 Q—K7 ch., 24 K—Kt3; 25 R—Kt3 ch., 25 Kt—Kt4; 26 P—KR4, 26 R—R2; 27 P—R5 ch., 27 K—B4; 28 R×Kt ch. with an irresistible attack.
22…Kg8Again careless play. K—Kt2 was correct.
23.Qg4+La Revista del Ajedrez justly points out that White could have won here by 23 Q—K8 ch., 23 K—Kt2; 24 Q—K7 ch., 24 K—Kt sq.; 25 Kt—K5, 25 P×Kt; 26 R—Q3, with an irresistible attack.
25.Nfd4This attack is ineffective. He ought to have been satisfied with a draw.
29.Rh3Completely throwing away an important move. He evidently overlooked the opponent's telling reply. Q—Kt4 ch. to which K—R sq. was the best answer, followed by Q×P would have enabled him to make a much longer fight.
