Game 22 in Philip W. Sergeant’s Morphy’s Games of Chess (1916), printed pages 65–67. Commentary from this edition; named earlier annotators remain credited in the notes. The printed score ends at 79..R—KB8, White resigns; the archive score continues through 80..Kg6. The source says that the time was not recorded.

1. 6…Be7 6..B—Q3 was the usual move in those days. Morphy’s influence, no doubt, did much to establish B—K2 in its place—and also the following Kt—QB3 instead of the older 7..Castles.
2. 8…f5 This, however, is not best. Morphy himself suggested afterwards 8..Kt—Q3 or B3. But 8..B—KKt5, Pillsbury’s favourite move, is now generally played, when White can only win a Pawn at the expense of submitting to a strong attack. If instead 9 P—B3, then 9..P—B4.
3. 10.cxd5 This opens a diagonal for Black’s QB. M.L. commends 10 Q—Kt3.
4. 13…Bd6 Black is suffering now for his early advance of the KBP and does not want the hostile Bishop at K5. White can decline the exchange with 14 B—KKt5, followed by P—B4, with fresh complications; but he selects the simpler course.
5. 16.c4 Here Löwenthal complicates again. 16 P—KB4 was both simpler and better.
6. 20…Rd8 Morphy pointed out later that 20..P—B4 was much stronger. If then 21 P—Q5, P—B3.
7. 21.Qa5 Löwenthal considered the line he adopted better than 21 R—Q1, P—B4; 22 P—Q5, P—B3; 23 Q—B2. It is doubtful.
8. 23.Qf4 White misses 23 R—K7, R—Q8 (if R—KB1 or Q×Q, White wins a Pawn); 24 Q—B8ch, R—Q1; 25 Q×KBP. Or 24..Q—Q1; 25 Q×Qch, R×Q; 26 R×P.
9. 27.Qc8+ Now there is no P to be picked up. If 27 R×B, R×Rch; 28 K×R, Q—Kt8ch; 29 K—K2, Q—B7ch; 30 K—K3, Q—B6ch; and Black wins back the Rook or draws by perpetual check.
10. 30…Kf8 With this move Black prevents the draw which White could have forced with 30 R—K8ch, B×R; 31 Q×Bch.
11. 34…Kg7 Threatening K—B3. White cannot now save his QBP.
12. 38…Rxa2 The game looks as good as ever. But White, helped by weak moves on the other side, puts up a hard fight.
13. 46…Kf6 46..P—QR4 was better (Maroczy).
14. 49…Re6 49..P—QR4 is still the right move.
15. 54…gxh5 54..R—B3ch and 55..P—Kt4 win without difficulty. Now it is difficult to see how Morphy could have won but for the blunder on move 63.
16. 63.Kf2 63 K—B4 reduced the game to a draw, Black being then unable to win White’s Rook for his Pawn and cut off White’s Pawn as he actually did.
17. 79…Rf1 White resigns. A game full of sins of omission, comments Maroczy.
