(My Australian rating is 1504. >Desperado hasn't competed much against rated players recently but might be about >2000. An earlier version once managed to fluke a win against an IM.) I occasionally beat Crafty, at full strength, but it isn't exactly about "chess" when I do. I have to (a) avoid a tactical mistake which is hard against crafty, (b) play into positions where I think it might not be able to whip up some sort of tactical activity, and (c) I use specific knowledge about what it does well and what it doesn't do well to help guide me. I probably win around 1 of every 20 games I play, when the games are longer (ie not blitz) so I can try to avoid tactical mistakes. But this is really helped because I know the program so well, particularly how it evaluates positions. It isn't "easy" to exploit it, but every now and then I get away with it. Of course, 1 out of 20 is not exactly spectacular...
