try [Site "?"]

I use "Site" to set win=1, lose=1.  then the Result tag will overwrite
these with the correct result.  In your case, you want 'em to be left
alone.  Since you don't have "Site" (lowercase site doesn't match the
proper pgn tag) it has zero wins and zero losses.  and Crafty won't play
any move with zero wins...
