Hi,
My program, EXchess, is a little more than a year old. (It started as
a simple one-ply evaluator until I learned more, thanks to rgcc
and ccc.) I've had it playing on FICS for a few months now where
it has slowly achieved a rating of ~1900 blitz. However, until recently
- other computer programs, such as crafty clones have defeated it
easily.
I'd like to report my program's first win against a crafty clone on
roughly
equal hardware. JPCrafty is crafty v14.2 running on a pentium 120 with
64 MB of ram. I have no idea what opening book it is using, if it has
any endgame tablebases, or if the operator has made any modifications to
the code. My program is EXchess v2.08 running on a Cyrix MediaGX
processor with 48 MB of ram. This processor runs my program about
10-20% slower than the pentium 133's we have at school, so my guess is
the hardware is about even.
Here is the game. I haven't analyzed it yet, but I observed the game.
A few weeks ago, my program would have been eaten alive by any crafty
clone, so I am quite happy with even a single win.
