Medley against Morphy, London 1858 — the first of three casual games, a Ruy Lopez Knight's Game in which Morphy (Black) wins a clear Pawn and converts with his usual ability. Notes by Löwenthal.
8.d4An interesting and singular variation arises if White now play Q. to K's 2nd, e.g.— 8. Q. to K's 2nd, Kt. to K. B's 5th; 9. Q. to K's 4th, Q. to Q's 6th; 10. Q. takes Kt. (ch.), K. to Q's sq.; 11. Kt. to Kt's sq. (the only move to save the mate), R. to Q. Kt's sq.; and, play as White may, Black must win.
14.Qd4Had he taken the K. Kt's P., Black would have played K. to Q's 2nd and then commenced a powerful attack on White's right wing.
19.Bf4Mr. Medley declined the exchange, probably under some apprehension of B. to Q's 4th.
24…Nd5Gaining a decided advantage in position.
29…Qxa2Winning a clear Pawn very ingeniously, after which the advantage acquired is maintained to the close with Mr. Morphy's usual ability.
31.Qxd8+As the game was lost by its nature, it perhaps mattered little what Mr. Medley played. This strikes us, however, as injudicious, with his adversary's Pawns in such strength on the Queen's side.
