Paul Morphy against Ernest Morphy, New Orleans 1850 — an Evans's Gambit. Löwenthal extracts the analytical variations from the Berlin 'Schachzeitung,' and Morphy crowns a brilliant and sound combination with a forced mate. Notes by Löwenthal.

1. 7…Bxc3 It is neither advisable here to take the Pawn with Pawn nor with Bishop, for such capture loses time and prevents Black from developing his game as speedily as is requisite, and enables White to bring his forces into rapid co-operation.
2. 9.Ba3 We give a diagram of the position here, and as no analysis of the variations that arise from the Bishop's taking the P. has yet been given in any English Chess work, we extract the most important from the Berlin 'Schachzeitung,' where they appeared in the volume for 1851, p. 63, premising only that Mr. Morphy does not at this point adopt the move recommended by the able author of the work mentioned, but favours the move in the text.
3. 10.Qb3 Mr. Morphy selects the best move, though 10. P. to K's 5th is also an effective mode of prosecuting the attack, and produces most interesting positions.
4. 12.e5 A very effective move, as Black is, in a manner, compelled to take the Pawn, and give up the privilege of castling with King's Rook.
5. 15.Ba6 The combination of which this move forms the key is both brilliant and sound, and favourably exhibits the truth of Mr. M's calculations.
6. 15…Na5 The inexperienced player will be surprised, no doubt, that the proffered Bishop was not captured; the following variations, arising from its being taken with Pawn, will show the consequences attendant on such capture.
7. 19.Rxc6 An excellent coup, the situation is so instructive that we annex a diagram.
8. 19…Qf5 It is obvious that the Queen would have been lost if the Rook had been taken.
