PyChess, a free, open source chess GUI and engine, distributed under the GNU Public License, both written in Python. Thomas Dybdahl Ahle started the project in 2006, with Bajusz Tamás and Justin Blanchard contributing in the meantime [1]. The GUI uses PyGTK and was originally developed for GNOME, compliant with its Human Interface Guidelines, but runs well under all other Linux desktops, and since PyChess 0.12 Anderssen rc4 released in August 2015, in parts re-written to Python 3 threading [2], also under Windows [3]. PyChess allows playing with the build in engine, with UCI and Chess Engine Communication Protocol compliant chess engines, or can act as online client of the Free Internet Chess Server (FICS). Further, PyChess supports many chess variants.
