	Greetings from Canada!

	GNUChess probably lost the game with 32. Rxf7  Kxf7  because it did a
4-ply search and missed a 5-ply mate.  But move 33. Qc1?????????  is still
confusing.  The "List" feature in GNUChess stores a great deal of
information about a game - I have used it below.  I set up the position
after Black's 31.... Qd4 with GNUChess (running on a 486DX2 50MHZ) playing
White at 40 moves in 30 minutes.  (Please replace (at) with the correct
symbol if you wish to Email me.)
