I got a copy of the rybka 2.3 engine wich I think is a fake since I was able to beat it and I'm pretty sure I'm not a WGM. It got the same options and stuff as rybka seems to have (I looked at the site). I tried it against the rybka 1.0 beta wich is free and after 5 games there were two draws and 3 wins for rybka 2.3. So now I need something stronger to test it against. Anyone have any idea what to try? Preferably something that works with Arena.

I don't know if it's strong to your liking, but I use Crafty; surely there are many more 'free' engines out there.

Thanks alot. The link you gave doesn't seem to work though.

Thank you, that works. Going to try them out against eachother right away.

 That's the FTP site so that you can download immediately, sorry it didn't work.  Good to know you got it anyway.  Remember there are other companion files to the executable.  (book.bin, bookc.bin and books.bin if you're in Windows)

Arasan it quite good

I am playing and comparing the Fruit, Phalanx, and Crafty engines right now.  For my first impression, I am liking the Crafty engine for its book.

They are all in the Ubuntu Repository if you swing that way.

-Freetard Hopmaster J 

• Crafty 20.1 (~2526 elo)
• Glaurung 1.02 (~2673 elo)
• Fruit 2.1 (~2754 elo ; also the base package of Gambit Fruit and Toga II)
• Gambit Fruit 1.0 Beta 4bx (~2790 elo)
• Toga II (~2810 elo)

I got this all from www.westportchessclub.org/links.htm

Cool. i ll have a look at them

 

This is great, I have been thinking about getting a Chess Engine for myself, but was unsure how to go about it.  I am downloading Crafty right now.

Der Bringer is also quite a nice and free program!

crafty is really good. Try it

 I once played with shredder and i can say its a good engine.

 

Rybka is the best one

On relatively short time controls, on my 2.1Ghz computer, Rybka 1.0 Beta, Fruit 2.3.1, Toga II and Spike 1.2 are all pretty strong. They're all free or open source.

 Did you try with Arasan 10.3 o 9.5

They are extremly performants

Bonne chance

I hope chess.com does not condone piracy of Rybka or any other chess software.

Nagaskaki is my favorite.......you can get it from chess.com downloads.....good GUI and playing strength

None of it is pirated, it's all just free...

Can anyone comment on the different playing styles of the free chess engines? Maybe compared to the fritz family?
