* 1min+1sec/move, 64 MB Hash, 1 Thread, 64-bit, Ponder off, no EGTB.
* 8 book moves: neither to little, nor too much. Allows engines to develop their own plan, while offering a large enough number of opening positions.
* Bayeselo, offset Fruit 2.1 = 2700 elo.

There is a bug-fixed Sloppy 0.2.3 on Jim Ablett's page.

Still a long way to go until Fairy-Max, I guess...

Surprised not to see Gull or Scorpio in your list...

* Gull is windows only
* Scorpio, at least the version I tested, is all buggy so I gave up

I managed to compile Gull for my Mac, and posted those patches to the sourceforge project. They should also work for Linux; Gull was pretty close to being cross platform already. I guess the patches were never accepted. In my testing, Gull version 1.0a is strongest, and is on par with Stockfish 1.5 and Junior 12.5.

I agree about older versions of Scorpio, but the latest from his git repository (2.7) is finally stronger than 2.0 and also more stable. I still had to hack its move formatting to get cutechess-cli to understand it though.

well for Gull if the author is not even willing to accept someone else's patch to make his code portable, it means he doesn't care about portability. And I *do*, so I'll live w/o Gull

I tested the JA compile of Scorpio, and it kept loosing on time or crashing, I can't remember. Where is the git repo ? I'll see if I can compile something out of it

For a start his code doesn't compile...

How are you building it?
The errors you show are a result of not linking with -lpthread -ldl.
However, Scorpio's Makefile does include these flags. I cloned from git://github.com/dshawul/Scorpio.git and didn't need any changes to make it compile.

i downloaded the latest git code and compiled by using the Make file as it is, using gcc 4.6.1. so the problem s be somewhere either in the code or in the makefile, no ?
