Game 157-Elkin in Philip W. Sergeant’s Morphy’s Games of Chess (1916), printed pages 220–221. Commentary from this edition; named earlier annotators remain credited in the notes. The source repeats the printed number CLVII after the preceding Morphy–Meek game. Source footnote: Lewis Elkin. There exists a photograph of Morphy playing chess with him at Philadelphia in October 1859, which is reproduced in Maroczy’s “Paul Morphy,” p. 312.

1. 5…Nf6 Considered inferior to the Paulsen Defence, 5…B—Kt2 (followed by 6 P—Q4, Kt—KB3; 7 B—B4, P—Q4; 8 P×P, Castles), into which, however, it can transpose by 6 B—B4, P—Q4; 7 P×P, B—Kt2!
2. 8…Nh5 See note on Game CCXXV.
3. 9.Qd2 This and White’s two succeeding moves are more original than sound. 9 Castles was usual. Morphy introduced 9 Kt—QB3, for which see Games CXC and CCVII.
