Hello support-team,

it is a computerchess-related topic e.g. running Python 0.99.3 https://github.com/pychess/pychess/releases/download/0.99.3/pychess-engine-20180928.pyz outsite its own graphical user interface https://github.com/pychess/pychess/releases/download/0.99.3/pychess-0.99.3-win32.msi on an external front-end like WinBoard Interface http://www.open-aurec.com/wbforum/viewtopic.php?f=19&t=51528 http://www.open-aurec.com/wbforum/viewtopic.php?f=19&t=51528  with protocol CECP http://hgm.nubati.net/CECP.html 

A detailed description (with all necessary configurations) how to accomplish this problem is hosted on my Google Drive chess collection https://drive.google.com/drive/folders/0B5Ao6h_yMCl6ay04RjVtUDVTUG8 > folder Pychess_20180928

Günther Simon from Germany http://www.rwbc-chess.de/ http://www.rwbc-chess.de/   reported that PyPy for Windows caused problems to run PyChess engine in contrast to WinPython or Python for Windows 3.

Best wishes,


PyChess 0.99.3 - WinBoard GUI

* Download WinPython 3.6.30Qt5 x64 (390 MB) https://github.com/winpython/winpython/releases/download/1.9.20171031/WinPython-64bit- https://github.com/winpython/winpython/releases/download/1.9.20171031/WinPython-64bit- 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 (configuration settings)

> PyChess_20180928 Editor (text document)

> PyChess_20180928 = renamed InBetween http://web.archive.org/web/20100922051419/http://home.online.no/~malin/sjakk/download/InBetween.zip http://web.archive.org/web/20100922051419/http://home.online.no/~malin/sjakk/download/InBetween.zip

> PyChess Zip application

* Run WinBoard GUI > Load first engine > PyChess_20180928.exe (without any commandline-parameters) under protocol WB-2

It will not run with PyPy https://pypy.org/download.html https://pypy.org/download.html on Windows, because there are only 32-bit PyPy installs for Windows available, while at least latest pychess.pyz seems to rely on some 64-bit Python stuff, which throws some known exceptions (according to Günther´s Google research) in this case.
