Game 58 in Philip W. Sergeant’s Morphy’s Games of Chess (1916), printed pages 122–124. Commentary from this edition; named earlier annotators remain credited in the notes. Tenth game of the 1858 Anderssen match. The source gives the playing time as about six hours.

1. 8.O-O Anderssen here departs from his line of play in the 6th and 8th games. He improves on his opening strategy considerably in the present game.
2. 12…Rh6 As White by his next move prevents Q—R5, Black only loses time by R—R3. On that square the Rook remains to little purpose until the 40th move.
3. 14…Bxc4 White threatened Kt—K5. But the capture gives White’s KB great scope.
4. 19.Be6 Tempting Black to shut in his Rook with P—KKt3. But Black has a complete answer.
5. 20.Bc4 If 20 B×P, P—KKt3, and the Bishop is lost. Maroczy proposes 20 P—Q5. But it is to be noted that he, following M.L., transposes Black’s 18th and 23rd moves, so that according to him Black has no Pawn on his QB3 yet. I follow J.L. on account of Black’s 21..R—QKt1.
6. 24…Qf7 Threatening P—QKt4, opening a way for one or both of his Rooks. But White easily frustrates this plan.
7. 26…Rg8 After this there is another discrepancy in the score, M.L. and Maroczy giving the next four moves in the following order: 27 R—R1, P—KKt4; 28 P×P, QR×P; 29 P—R5, B—Q3; 30 P×P, P×P.
8. 29…Bd6 Steinitz calls this a bad strategical error, after which Morphy’s game is lost in a few moves. It is certainly a rash manœuvre, in view of the position of Black’s King and White’s QB.
9. 31.Ra8+ Maroczy here suggests as stronger 31 P—B5, P×P; 32 P×P, B—B1 (if B×BP, 33 R—R8ch, B—B1; 34 B—B4, Q—KKt2; 35 Q—Kt2, followed by Q—Kt8); 33 R—R8, K—Kt2 (if K—Kt1; 34 B—K5, Kt—Q4; 35 B—Q6, R×B; 36 P×R, Kt×P; 37 Q×BP); 34 B—B4, Q—K2; 35 R—Q2, Q×P; 36 R—Q1ch, K—R1 (if K—Kt3, then 37 B—B7ch, K—Kt2; 38 B×Ktch); 37 B×Ktch, R×B; 38 Q—B3, R—Kt3; 39 R—KB7, and wins.
10. 34.Qxe8+ 34 Q—Kt7 was the right move (Steinitz).
11. 36.Bc4 J.L. claims that 36 R—B2 is speedier. But what Anderssen plays is excellent, though he should have followed it up with 37 P—Q5dis.ch, instead of P×P.
12. 42…h4 According to J.L., 42..R—Kt5 would at least have drawn the game, for if 43 B—K2, R—Kt1, with a good game. But White can reply 43 R—R7, P—R5; 44 R—R6, P×Pch; 45 P×P, B×Pch; 46 K—B1, K—Kt3; 47 R×Pch, Kt—B3; 48 B—K7, B—R5; 49 P—Q5, etc. If here 45..R×P; 46 R×Pch, K—Kt4; 47 B—K1ch, K—Kt5; 48 R—Kt6ch, K—R3, White mates in 2 moves (Maroczy).
13. 47.Bf1 Of course he cannot play 47..R×KP because of 48 P—R7.
14. 58…Nf3 Would Black have done better with 58..Kt—B8? The following moves have been agreed as best: 59 R—B3, P—B5; 60 P×Pch, K×P; 61 P—Q5, K—K4 (61..P—K6; 62 P—Q6 is to White’s advantage). Now J.L. gives 62 R—B6, but Maroczy’s suggestion 62 K—K1 is better, e.g. 62 K—K1, Kt—Q7 (if R—R8; 63 K—B2, P—K6ch; 64 K—Kt2, P—K7; 65 K×R, P—K8(Q); 66 P—R8(Q)ch, etc.); 63 R—B6, Kt—B6ch; 64 K—Q1, Kt—Kt4; 65 P—Q6. Here, strange to say, Maroczy does not give the natural reply 65..Kt×P, but only P—K6, continuing 66 R—B1ch, K×P; 67 R×Kt, K—K2; 68 R—Kt7ch, K—B1; 69 R—R7, R—R6; 70 B—B4, R—R7; 71 R—B7ch, K—K1; 72 R—KKt7, and wins. Now if 65..Kt×P, a very interesting continuation comes about: 66 P—Q7, R—R8ch; 67 K—B2, R—R7ch; 68 K—B3, R—R6ch; 69 K—Kt4! (the point of this move, the suggestion of Mr. Amos Burn, will be seen on move 71, when it is essential for White’s K not to be at B4, since if he is driven to Kt5, Black can continue 71..R×Bch; 72 R—B5, R×Rch; 73 K×R, Kt—B8!); R—Q6; 70 B—Q5, R—Q5ch; 71 R—B4, R×B; 72 R—B5ch, R×R; 73 P—Q8(Q). If Black plays here R—Q4, leaving his Knight to be taken, White’s win requires proving.
15. 66…Kg7 Black has a hopeless position. If 66..K—B4; 67 P—Q6, K—B3; 68 K—K3, and nothing can stop the progress of the White King.
16. 74…Kxh7 If 74..K—B1, 75 P—Q6.
