Game 48 in Philip W. Sergeant’s Morphy’s Games of Chess (1916), printed pages 101–102. Commentary from this edition; named earlier annotators remain credited in the notes. Eighth and final game of the 1858 Harrwitz match. The source heading gives the date as September (? October), while the archive entry gives October 4, 1858. The source says the time was not recorded.

1. 3…Bg4 Universally condemned by the analysts. It is the defence with which Lasker lost to Van Vliet (White) at Amsterdam, 1889. Blackburne, however, has played it on several occasions, not without success.
2. 4…Bxf3 On account of the continuation in the next note this is not usually played, but 4..Kt—Q2, in the hope of a quick development to compensate for the Pawn lost. Then 5 P×P, B×P; 6 B—K2 is best (Van Vliet—Lasker). 4..Q—K2 was Blackburne’s move against Pillsbury in the 1900 Cable Match.
3. 5.Qxf3 Morphy did not like an early exchange of Queens—Game XLVI is a rare example—or else he could have played 5 P×B, P×P; 6 Q×Qch, K×Q; 7 P—KB4, P—KB3; 8 R—Kt1, P—KKt3; 9 P×P, P×P; 10 Kt—B3 (M.C.I., 152).
4. 7.Qb3 For the superior 7..Q—K2 see Game LXXIX. 7..Kt×P is fatal.
5. 18…Rhb8 The Q side attack at which Black aims is harmless in comparison with White’s K side attack; and this Rook would have stood better in the centre.
6. 30…Nc5 If 30..Kt—K2, 31 B—Kt4, and all is over.
7. 59.d6+ That Harrwitz did not resign long before this must presumably be attributed to pique. He now gave up the match.
