It crushed all weak chess engine it played ! And know very well how to do that !. Now plays with some better engines.
Two tricks:
1.-if you want Sunfish to play with withe - edit test.py in the second line of "def xboard()" (the fen);
2.-if you have installed on your machine only Python 2.7/3.3 interpreter ( and not pypy) edit the first line in xboard .py (replace "pypy" with "python").
SilvianR
Just a mild sample of its savage play. A J_E_W_E_L IN PYTHON! Take a look please ,also, at the architecture of this chess engine !!!!

Re: Now- a better support for the WB protocol !!!
Download again this masterpiece:
======================================
https://github.com/thomasahle/sunfish/a ... master.zip
======================================
Put in sunfish-master folder a Sunfish.bat file with the following structure:
=======
C:\Python33\python -u xboard.py
=======
and a logo with the name:
Sunfish.bmp
And your engine is able to play with both white/black colours, supports . bin book...........
Rests only the qsearch problem !!!
I will include (like a delicious bonus) this engine in my future Java +Python SECOND LEAGUE 2014 !!!!
MILLION THANKS, THOMAS !!!

The 2-nd of March 2014. Still nothing. A such beautiful engine ! Why ???

It is the CCW Update Information section of February, 27th. It lists Sunfish as a novelty without engine version. It also credits the discover to you! I guess that the info of the link you provided and the info of the link I post are not synchronised. I recommend you the following link:Update Information: February 27, 2014 wrote:Sunfish ??? (WB)
new engine by Thomas Dybdahl Ahle
engine discovered by the incomparable Mr Silvian 'Ruxy' Sylwyka
Python source, didactic engine
- source code only engine
- requires installion of a Python interpreter
- run 'test.py' for Winboard engine
- engine doesn't do minor promotion or draws of any kind
- engine has no assigned version number
http://github.com/thomasahle/sunfish/ (source code)

Regards from Spain.
Ajedrecista.
http://www.computer-chess.org/doku.php? ... _only_list
I suspect that installing a Python interpreter, editing source code, and running Python engines are beyond what most computer-chess people expect. If an engine contains a coherent package that simplifies usage, then I list it with the 'normal' engines at the top of the list.
If anyone uses this technique:
http://www.logix4u.net/component/conten ... hon-script
and can post the exe somewhere that is publicly available, then I will list it as a normal engine.
If the author cleans up the source code so it does not need editing, then I will probably list it with the normal engines. I would like to see an engine version number as well.

Re: SUNFISH (2)-THOMAS ADDED QSEARCH & NULL-MOVE !!!!!
Hey men !
Sunfish rules ! Thomas just added qsearch & null-move to this beautiful chess engine !
https://github.com/thomasahle/sunfish/a ... master.zip
A very short test shows me a fantastic attacking entity ! Versus Mr.James Swaffort last creation !
Try it !
A jewel in Python !!!
Have a nice day & night ( and.....don't forget Ukraine ) !

Re: Installing Sunfish (2) in Arena GUI (MANUAL -:)))
1.-download Thomas original archive:
https://github.com/thomasahle/sunfish/a ... master.zip
2.-unzip somewhere on your machine;
3.- add the following two files (Sunfish2.bat and Sunfish2.bmp):
http://bayfiles.net/file/18qul/GdgR8g/for_Arena_GUI.zip
4.-download & install (if you haven't it yet) Python 3.3 interpreter (let the default installation path C:\Python33, or change the path in Sunfish2.bat file) from here:
http://www.python.org/ftp/python/3.3.4/python-3.3.4.msi
5.-on Arena GUI - install Sunfish2.bat like Wb engine.
Have fun !

Re: Increasing the performances !
Using pypy interpreter you can increase the speed /performances of this wonderful Python engine.
Download pypy 3.2.1 from here:
https://bitbucket.org/pypy/pypy/downloa ... -win32.zip
The Sunfish2.bat (using pypy) file (for Martin's Arena GUI) has -now - the structure:
@@@@@@@@@@@@@@@@@@@@@@@@@
C:\pypy3-2.1-beta1-win32\pypy.exe xboard.py
%%%%%%%%%%%%%%%%%%%%%%%
A good boost of Herr Sunfish !

I have to agree with you Ruxy, the engine can be very aggressive. Mind you, so can others.
