Morphy against Löwenthal — the fourteenth and final game of their 1858 London match, on winning which Morphy took the match (Ruy Lopez Knight's Game).

1. 7.O-O If Q. to K's 2nd, the reply on the part of Black would have been Kt. to Q. B's 4th.
2. 12…Qe7 The second player has now a game as good as can be expected in defending the Ruy Lopez attack.
3. 16…Bxc2 This move may be said to have been the cause of all subsequent embarrassment; Mr. Löwenthal should have considered that the sacrifice of the Pawn was only offered on valid grounds.
4. 17.f4 Mr. Morphy once more takes due advantage of his opponent's weak play.
5. 18.e6 An admirable move, threatening to win a piece by Q. to Q. B's 3rd, and so improving his position as to make the game in a manner his own.
6. 23.Re5 This again is beautifully played; for if Black exchange Rooks his game would have been compromised, as follows: 23. R. takes R. 24. P. takes R., Q. takes P. 25. R. takes P. (ch.), and the Black Queen is lost.
7. 33…b5 The sacrifice of the two Pawns was compelled, and Black's position was altogether so embarrassing that successful extrication out of it appeared very unlikely. The apparently feasible move of Q. to K. B's sq. would have led to no more beneficial result than this advance of the Pawn; the answer thereto would have been P. to K. Kt's 4th.
8. 37…Rb6 Here P. to Q. B's 3rd would have been a better move.
