Game 45 in Philip W. Sergeant’s Morphy’s Games of Chess (1916), printed pages 97–98. Commentary from this edition; named earlier annotators remain credited in the notes. Fifth game of the 1858 Harrwitz match. The source gives the playing time as five and one-half hours.

1. 4…Be7 In the 3rd game he played B—Kt5. The text-move is better.
2. 8…Nh5 Freeing his position—and, as Maroczy points out, showing the disadvantage of White’s 4 B—Kt5 against the Dutch Defence.
3. 12.f4 Kt—Q2—KB3 looks a natural development.
4. 14.gxf5 Emphasizing the weakness of his QP. 14 B—Kt1, followed by P—KR3, was necessary.
5. 16…Qh4 Good; but 16..Kt×B; 17 Q×Kt, Q—R5 was perhaps better still.
6. 22.b4 White improved his game considerably by his 17th–20th moves. The same, however, cannot be said of his last two. P—R3 helped the hostile Knight on his long journey to KKt5, whence he cannot be dislodged; and P—QKt4 leaves the QBP weak, as in the 3rd game. But the latter weakness need not have become pronounced in the present game.
7. 34.Qg2 White has a difficult game owing to his weakness on the K file. But by exchanging Qs he enables Black to operate on the QR file more effectively. Maroczy suggests 34 P—K4.
8. 37…Ra8 With Kt×P Black could have gained three Pawns for his Knight.
9. 41.Bxe4 R×Kt was much better. If then 41..R—Kt6; 42 R—K8ch, K—B2; 43 R—QKt8. If 41..K—B2, perhaps 42 K—B2 gives the best chance of a draw.
10. 42.Bf3 If R×QBP, 43 R—K8ch and 44 R—QKt8.
