Morphy against Lichtenhein, New York 1857 — the second casual game, an Evans Gambit. Notes by Löwenthal.
6.O-OP. to Q's 4th is now generally preferred.
6…Nf6P. to Q's 3rd is usually played at this point.
14.Nc3Had White taken Kt. with B., Black would have taken P. with Q., and continued his defence with Castling, having a safe position.
15.Ne4Correctly played; the Knight, thus favourably placed, enables White presently to commence a powerful attack.
19.Rxe6R. takes Kt., and then Kt. to R's 5th, seems White's natural line of play, but the attack adopted by Mr. Morphy is much more brilliant and effective, and produces so interesting a position, that we give a diagram of it.
20…Ke7Black's position is extremely critical; we believe this to be the best move at his command.
22…Qxd4He should have played 22. Kt. to K. B's 4th.
