Jul-25-05  Knight13: 26... Be6?? is a blunder. 26... Bd7 is much better, as Morphy pointed out.

Good game.

Feb-27-08  wolfmaster: Cool checkmate!
Oct-26-08  just a kid: It's funny that Black opens up the g-file for himself,but lets White get it.
Dec-27-10  Llawdogg: Nice annotations from Paul Morphy. McDonnell never did develop his queen side and this did him in.
Dec-27-10  Tigranny: Wow what a blunder, Be5, blowing the game away. I liked Paul Morphy's annotations too.
Feb-01-12  Knight13: 23. f4 just throws away a pawn for no reason. It's like 20... b5 in this game La Bourdonnais vs McDonnell, 1834. I wonder why Morphy didn't comment on that move.
