Hello Silvian,
I added Chess Mastah , Smashpy and Python Chess Library to
"Native Engine List" of CCWiki.
Sunfish
I have installed Python 2.7.6 ttp://www.python.org/download/releases/2.7.6/ and PyPy 2.2.1 win32 http://pypy.org/download.html on my Intel Core 2 Duo E6600 with Windows XP SP3-32 bit OS.
With Notepad++ http://notepad-plus-plus.org/ a .bat -file like
python -u test.py can be created - but in two 5 min-games under Arena-GUI Sunfish executes only moves with the black pieces and after 1.e4 Nc6 2.d4 e5 4.Nf3 Nf6 4.Nc3 the program forfeits because of time exceeding (no further moves were made)
It would be surely a good idea to publish a step-by-step manual for running Sunfish into external graphical interfaces.
Best wishes,
Norbert :

Hey guys, thanks for bringing this up. I pushed a new module to github, which adds better cecp/xboard/wb support. It also fixes the hang Nobert was talking about.
I would love to add qsearch to sunfish. Right now horizontal effects make it blunder pretty badly in some positions. I'm not sure what the simplest way to do it would be though.
I also made some graphics inspired by Ruxy:

Welcome to CCC, Thomas! And thanks for sharing your engine with us. I will be trying out Sunfish very soon.

Yes, you can use Sunfish to play a
console-based match with a double-mouse click on sunfish.py
your move: e2e4
searched 67590 nodes depth 6 score -107
my move: b6c6
your move: d2d4
searched 26472 nodes depth 5 score 160
my move: e7e5
your move: d4d5
searched 46168 nodes depth 5 score 101
my move: c6e7
etc.
But playing under WinBoard-protocol with a bat.-file python -u test.py
or python -u test.py -xboard failed with Arena http://www.playwitharena.com/ failed because no moves were made
(in contrast to yesterday) by the program
Be aware that you can run another
Python Engine "Shatranj"
https://code.google.com/p/shatranjpy/ with a .bat-file like
python -u shatranj117.py -xboard to run normally into the same interface (with Python 2.7.6) and an editor like Notepad++
Best wishes,
Norbert
