An Evans's Gambit at the odds of the Queen's Knight. Black's defence soon goes astray, and Morphy, a piece behind, builds an attack that ends in a forced mate.

1. 6…Bb6 In some of the games between the same players, at the same odds, Black adopted the defence of 6. K. Kt. to B's 3rd, undoubtedly the best move at this stage.
2. 7…d6 Not a bad move when receiving the odds of a piece, if properly followed up.
3. 8…Nxe5 He should have played 8. Q. B. to K's 3rd.
4. 20.Rd1 From this point to the end, Black has a game very difficult to defend; e.g.: 20. ... Kt. to K's sq.; 21. Q. R. to Q's 5th, Q. moves; 22. Q. B. to Kt's 5th (ch.), Kt. or R. interposes; 23. P. to K's 5th, with a winning game.
5. 23…Nf6 And Mr. Morphy mates in three moves.
