Just to wet your appetite here is a shot where I play with ICC problembot a famous puzzle.

looks very good

will it support opening books (engines following the book in the opening)? one of very few drawbacks of older versions.

Hello,

I have installed PyChess 0.99.1 on Windows 7 SP1 32 bit successfully, but if I make a double-mouseclick on the python-chess engine (.exe-file) > cf error indication:
cx_Freeze: Python error in main script
Traceback (most recent call last)

File C:\python34\lib\site-packages\cx_Freeze\initscripts\Console.py
line27, in <module>
File lib/___main___./py, line 21 in <module>
File lib\pychess\Players\PyChessCECP.py, line 93, in run
File lib\pychess\Players\PyChessCECP.py, line 35, in get_input
RuntimeError: input (): lost sys.stdin

It is possible to run python-engine into other GUIs like WinBoard Interface or Arena too?

On Windows python-chess engine (.exe-file) is only usable inside PyChess GUI. If you want to run python-chess engine outside of PyChess GUI you have to grab the latest engine from https://github.com/pychess/pychess/rele ... 161204.pyz
and run it with a Python interpreter. .pyz files are python executable zip files. See https://blogs.gnome.org/jamesh/2012/05/ ... zip-files/

IIRC 0.12.4 only had changes for Crazyhouse and I already tested it long ago for Crazyhouse?
For chess I still have 0.12.1 as the last with relevant changes and after extracting the new PyChess installation I see it is still the same.

BTW I always run it (the pychess-engine.exe!) without any problems through inbetween w/o any special commands in Winboard.

Code: Select all

[InBetween]
Debug := 3
CommandLine := C:\PyChess\PyChess-engine.exe
Log := PyChess.log

Code: Select all

0.000: - Starting server: C:\PyChess\PyChess-engine.exe
1.856: - Priority class set to normal
1.856: - Thread priority set to normal
6.193: > go

IIRC tournament time control support was added after 0.12.1
So in theory 0.12.4 should produce less forfeit on time games.

a short explanation how to run PyChess 0.99.3 WB-Engine on WinBoard-GUI including the necessary files is here:
https://drive.google.com/drive/folders/ ... jVtUDVTUG8
Thank you Günther!


PyChess 0.99.3 - WinBoard GUI

Download WinPython 3.6.30Qt5 x64 (390 MB) https://github.com/winpython/winpython/ ... 3.0Qt5.exe and install it on a drive e.g. C:\
This procedure can take more than 30 minutes.

Create a directory on C:\Engines\WB\PyChess_20180928 with the following working components:
> InBetween
> PyChess Editor (text document)
> PyChess Windows executable file
> PyChess Zip application

Run WinBoard GUI > Load first engine > PyChess.exe (without any commandline-parameters) under protocol WB-2

PyChess 0.99.3 vs. Fairy-Max: +0 =1 -9 (0.5:9.5)

Just a quick note:

In the example setup I sent to you, there is no

> PyChess Windows executable file

actually this is just the renamed Inbetween.exe itself.

Also you have of course to call it by the exact name in WB or Arena or Cute or whatever runs native
xb programs, or you have to rename it to your taste. The current name is PyChess_20180928.exe
in my example and not PyChess.exe (this is my usual naming convention).
(Also the path is my usual folder naming convention, which could be changed of course,
if adapted in the inbetween.ini file - same if using a different python install path)

and a not related side note:

It will not run with pypy on win, because there are only 32-bit pypy installs for win available,
while at least latest pychess.pyz seems to rely on some 64-bit python stuff, which throws some
known exceptions (according to my google research) in this case.
