Mar-19-04 Whitehat1963: Suddenly it's over!
Yes. The b2-square was a <LOOSE> mating focal point next to the White king and 25 ... ♘c4! brings in the Black a5-knight to coordinate with the Black c3-queen on this target.
White's only defense to the mate threat of 26 ... ♕b2# is to play 26 ♕x♘ so he resigns.
Jan-13-09 ungeneral: Is 4. ..Bc5 really a good move? Can it be played? If so, what is the reply to 5. Nxf7?
The statistics at Opening Explorer bear this answer out well. White's choice of fifth move in this game is much better.
Infohunter: Oh, and yes, as wild and wooly as this 4...Bc5 is, experience has shown that it offers Black good practical chances--a reality which I would agree is counterintuitive.
Despite the stats supplied by <Infohunter>, this verdict is incorrect; 5....Bxf2+ 6.Kxf2 offers no more than a draw against proper defence, though this may be easier said than done. Nunn has done a fair amount of analysis on this, which debunked the above conclusion.
