Hi,
today I played a little-welcome game with Crafty17.09 but experienced a rather
strange outcome .
First the game ( Shredder on PII300 , Crafty on PIII500 , comments by Shredder
) :

[Site "?"]
[Date "2000.03.05"]
[Round "?"]
[White "Shredder 4"]
[Black "Crafty 17.9"]
[ECO "C99"]
[Result "1-0"]

42. Rg8# {+M1/1 0s} 1-0
Not too interesting , much of a book victory .
But crafty felt like dealing with it in another way ( output from crafty-logfile
) :

1/2-1/2 {stalemate}
White(43): result 1/2-1/2 {stalemate}
White(43): force
White(43): quit
execution complete.
So : stalemate or checkmate ?? This is the question :-) ...
