I am new to computer chess. I have downloaded crafty. It is pretty

program out there?

Thanks

If you have DOS, try Rebel 12, its a beast. Even on an old Celeron 400mhz,
it rates 2450, and on a P4, it is a true monster.
Also Jester which is written in HTML, and tiny, is just amazing and beats my
Fidelity 2100 Chess computer!!!

Fruit 2.1 from Fabien Letouzey. An incredible strong chess engine, on
par with some of the best current commercial programs. For example,
Fruit 2.1 came in 2nd place on the current Computerschach und Spiele
Rating List, outperforming titans like Fritz 8, Junior 9 and Hiarcs 9:

Jester's actually written in Java and isn't all that strong -- I've beaten
it on the default settings. It's on the web at

At the moment strongest seems to be Fruit 2.1. I recently run a little
match tournament in my linux box between 4 engines Fruit, Crafty,
Glaurung, Yace. Fruit won big, scored 20 from 27 games, second place
scored 13 from 27. so Fruit was massive 7 points ahead.

Does anyone know of an engine that is truly within the playing range of
2000-2100, or which can be adjusted to that level?

Both Shredder Classic and Shredder 9 UCI at www.shredderchess.com have
a "Limit Strength" option, from 1000 to 2400, that seems better than
most. Delfi is also a very good adjustable winboard engine that seems
to make more subtle mistakes. The free version is only adjustable from
1250 to 1700, but there is a version available for 19.00 USD that is
adjustable in the range 900 - 2200. If you try either of these
options, I'd be interested to hear your impressions, as you're a
significantly stronger player than I am...

Pete,

I already have Shredder under the Fritz interface. How is the program you
mention different? Can I use it under the Fritz user interface? I admit I
forget all that UCI stuff.

Thanks,

Angelo

Hi Angelo,

The two Shredder engines that I mentioned are UCI instead of Chessbase
engines, and come with their own interface instead of the Fritz
interface. If you have a recent version of the Fritz interface that
supports UCI, these engines could also be run inside of Fritz, but you
would end up using the Fritz opening books instead of the ones supplied
with these versions of Shredder.

The latest version of the UCI protocol, written by Stefan Meyer-Kahlen,
the author of Shredder, supports a limit strength function directly
from the engine. When you use this feature the engine determines how
to weaken itself to the appropriate level rather than the interface
making the decision. To me, it seems like SMK's limit strength feature
in Shredder produces a more "realistic" result than the handicap modes
in Fritz provide.

If you do try it, you may need to give it a shot in the Shredder
interface (which is excellent by the way) for best results. I know it
will work in Fritz, but you'd need to be careful with opening books and
the game mode used to get the expected results without the interface
hijacking too much of the functionality.

If you go to the shredderchess.com web site, they have a trial version
of Shredder Classic available for download. Let me know what you
think!

Pete
