Laroche against Morphy, Paris 1859 — a casual game opened with the King's Bishop's Pawn. Notes by Löwenthal.
10.Neg5P. takes P. en passant would not have been so good, as Black would have retaken with his Bishop; and White dare not then capture the Q. B's P. with Knight, on account of Q. to R's 4th (ch.), &c.
13…Bb7The Bishop, thus posted, commands an important diagonal, and during the progress of the game, his power becomes manifest.
15…g5A very good move; Black is now enabled to take and maintain the attack.
18.Qe2This was perhaps best, and was played in evident anticipation of Black's next move.
26.g4Hazardous play, plunging White's game into immediate difficulty.
28…Qb7Securing a Pawn, and eventually the game.
31.Rxf3This reduces the game to an ending of a very simple nature.
