Sep-30-04  iron maiden: And we thought Tripoli was a blunderfest...
Aug-02-06  Knight13: I think White lost his patience and didn't try to find the best moves in the winning position.

May-04-09  sirfraix: After 19. Qh5 Morphy says: ▼ White has now acquired a winning position. But the variation explained by him: 19...h6 20.Rg1 (best) Bxc1 ?? overlooks the move 20... Be8! that neutralizes the white attack. Objectively 19. Bxh7+ looks better, like in nimh analysis.
Aug-11-10  Blunderdome: Yes -- Fritz and Morphy disagree on several points here.
Feb-02-12  Knight13: <Yes -- Fritz and Morphy disagree on several points here.> And unlike people who would rather let the computer do the thinking for them instead of doing it themselves, Morphy was actually very good in his assessment of the positions and ideas needed for White to win.
Apr-24-14  dernier thylacine: TO KNIGHT13: the computer can be a usefull help to find and point quickly tactical flaws, it does not mean necessary no more use his own brain...
May-24-15  RookFile: 23. Bxh7! was the move. For a human like McDonnell, I think he should have found that one.
Jun-22-15  MindCtrol9: This game is very instructed even White lost, one can see the ideas Mc Donnell had.He had a won game.
