I am tempted to say "agreeing to continue the match after Fischer's protests!" which some argue was a key psychological defeat. If you're looking for specific moves that were mistakes, there are a few candidates. I haven't looked at all annotations, but have Kasparov's My Great Predecessors, vol 4 handy and looking over his notes, it would be either (...
I found a game where castling takes place on the 40th move in a postion that is truly that of an endgame. Tim Krabbe lists as the 103rd most fantastic move in chess history.
