Morphy at the odds of his Queen's Knight against Mr. Worrall — a King's Gambit Declined; a well-supported advanced Pawn gives White a decided superiority. Notes by Löwenthal.
11.c4White has now obtained a fine attacking game.
17.d6This advanced Pawn, being well supported, gives White a decided superiority in position, which is augmented by the K. B's raking an important diagonal.
18…Nc6The best move, as White threatened to play P. to Q. Kt's 4th with great effect.
25.f5From this point to the end Mr. Morphy conducts the game with all his usual ability.
