To the best of my knowledge, it was Cray Blitz.  It beat USCF Master Joe
Sentef (2260) in the Mississippi Closed championship in 1981.  The game was
published with CB analysis in Chess Life a month or two after that tournament.

Belle was the first program to reach 2200+ and was awarded the 'life master'
certificate in October of 1983 if I recall correctly.  I could probably dig up
the game if needed.  It was 'interesting' with lots of swindle opportunities
near the end to enter a KB+2rook pawns, with the _wrong_ bishop.  Fortunately
Cray Blitz had that knowledge even in 1981.  Ken reported that Belle didn't
understand it and couldn't find the correct move in tournament time controls.
(this was a 40/2 event)..
