Morphy at the odds of Pawn and move against Mr. Devinck at Paris — a cramped formation from which Morphy's pieces break loose and overrun the board. Notes by Löwenthal.

1. 10.exd5 This gives Black some freedom. It would have been better play to have taken with the Q. B's P., when Black's game would have remained decidedly cramped.
2. 15.g4 An inversion of the order of this move and his next would have been more to the purpose.
3. 17.Be3 Badly played, allowing Black to gain such an advantage in position as must secure him the game immediately.
4. 17…Bd3 Taking instant advantage of his adversary's weak play. After this White's game was beyond all hope.
