In the game:

  1.      e4      e5
  2.     Nf3     Nc6
  3.     Bc4     Nd4
  4.    Nxe5     Qg5
  5.    Nxf7    Qxg2
  6.     Rf1   Qxe4+
  7.     Be2    Nf3#

Crafty seems to have book moves to cover till Qxg2, so Nxf7 was in it's
book, that does not mean that it was a good move, it just means that it
was in the book, if I had turned the opening book off, it might have
said something about it.

Crafty might have played 5. Bxf7+

But as far as annotating Nd4 with "!" goes, that must have been the
original poster, I never actually looked at the game.  Judging from
Crafty's score of the searches, I'd say that Black did a great job of
controlling things.
