Morphy at the odds of his Queen's Knight against an amateur — the original Muzio Gambit, conducted with his usual dash. Notes by Löwenthal.

1. 5.O-O There are at this juncture three moves which may be advantageously adopted by the attacking player, viz.: Kt. to Q. B's 3rd, invented and favoured by McDonnell; P. to Q's 4th, analysed by Ghulam Kassim; and Castles, the move in the text, constituting the original Muzio Gambit;—of the three, we prefer Castling.
2. 6.Qxf3 The best move according to the Handbooks (German and English).
3. 6…Qf6 This has been pronounced the best move.
4. 8.Bxf7+ A novelty; and an ingenious deviation from the ordinary line of play, which all the authors have recommended, viz.: 8. P. to Q's 3rd. The move made leads to positions of a most interesting nature.
5. 8…Kxf7 K. to Q. B's sq. would have been better, but even then White would have had a fine attacking game.
6. 10…Qf6 Taking the Kt's P. with Queen would have been very ill-advised, because White would have checked with the Q. at Q's 5th, and then played his B. to Q's 4th, &c.
7. 11…Qg6 There is nothing better on the board, for if the King go to K's 2nd or Kt's 2nd, White captures P. with R., and wins with ease.
8. 12.Rxf4+ Pursuing the game with his usual dash and spirit.
