I am reminded of an ACM event I participated in where Cray Blitz was playing
Deep Thought 2.  We had played a very poor book line and were getting crushed.
I called the TD (Mike Valvo) over to resign (that was a requirement at ACM
events, resignations had to be approved by the TD or the game had to continue).

I said "Mike, we are at -7, deep thought is at +5.  We'd like to resign.  We
have had this score for several moves in a row now.  He stopped, studied the
position, and said "play on, Bob."  I asked "why".  He responded "look at the
board.  material is equal.  We have several hundred people watching in the
playing hall here.  Many think this game is going just fine for both sides.
Wait until you actually lose the piece and pawns on the board, then everyone
will understand why you are resigning."

That seems to fit game 3, IMHO.

Just look at game two before you say that.  Simple blunder a 1500 player
would spot in seconds.  It _does_ happen.  Perhaps not often, but not
often != never.
