SUNFISH - a new chess engine written in Python !

[thomasahle]

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.

[Norbert Raimund Leisner]

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

Hi all !

1.-download the new archive (28-02-2014);
2.-replace the test.py from this archive with the old test.py file (it has xboard enabled). If you don't have the old test.py edit the new like in the below image !
3.-under Winboard GUI use the following .ini lines:

"C:\Python33\python -u C:\WbEngines\sunfish\test.py" /fd="C:\WbEngines\sunfish"

the same for the second directory

You can replace with your locations of Python interpreter and test.py file !

THANK YOU THOMAS FOR THIS NEW ENGINE WRITTEN IN PYTHON !!!



A nice Saturday for everybody here !

How strong do you estimate Sunfish to be?
