I don't doubt this. I referred to the position where Nxf5 was played and to the
thread starting with http://www.talkchess.com/forums/1/message.html?314428. I
started a new thread, because that message will not be seen anymore with a
default listing of the forum (and will probably dissapear altogehter tomorrow).
The original claim was, to find Nxf5 with a draw score. I think, with best play
white will win even after Nxf5.

In my game, white moved 70. Ke6. I think, white will win by force, then.

Perhaps black had drawing chances even later in this game.
