Game 188 in Philip W. Sergeant’s Morphy’s Games of Chess (1916), printed pages 246–247. Commentary from this edition; named earlier annotators remain credited in the notes.

1. 6.Nd5 There is now a resemblance to a class of positions in the Four Knights’ Game, where one side or the other plays Kt—Q5.
2. 6…b5 Tarrasch–Schlechter, Ostend, 1907, ctd.: 6…B—K2.
3. 10…exd4 This order of moves 6–10 is given in the record of the game published in Brentano, December 1881, where it is said to have been taken from the first number of a new German magazine, Vom Fels zum Meer. In Lasker’s Scrap Book, January 1907, the moves are given in the following order: 6 Kt—Q5, B—R4; 7 Castles, P—QKt4; 8 B—Kt3, P—Q3; 9 P—Q4, B—KKt5; 10 P—B3, P×P.
4. 11.Nxf6+ 11 P×P, B×Kt; 12 P×B is claimed by Lasker as in favour of White, whose free development and strong centre make up for his doubled Pawn. As the game actually went, White gave his opponent the opportunity for a most complicated sacrificial combination.
5. 13.Bxa8 13 B—Kt5 looks very strong.
6. 16.Qg5 16 B—B6ch has been suggested. But Black can play 16…K—B1; 17 P—K5 (if Q—Kt5, P×P), P×Q; 18 P×Q, B×B; 19 P—Kt4, P×P; followed by 20…P×B(Q), with an overwhelming preponderance of force. Black would, of course, avoid 16…K—K2 here, because of the reply 17 P—K5, P×Q (if 17…QP×P, White mates in 2; while 17…Q—Kt3ch or Q—K3 is completely answered by 18 Q—Kt5ch); 18 P×Qch, etc.
7. 17…Ke7 Now this move is perfectly safe, and Black proceeds to win in incisive style.
8. 27.Rf1 R—R3 would have prolonged but not saved the game.
9. 30…Rh6# Although this game is put in the Appendix by M.L. and Maroczy, it seems reasonable to accept its genuineness. Its date is perhaps doubtful. Brentano assigns it to 1858 or 1862.
