'''''PyChess''''' is a [[free software]] [[chess]] client developed for [[GNU]]. It allows users to play offline or online via the [[Freechess|Free Internet Chess Server]] (FICS). PyChess also incorporates a built-in [[chess engine]], which in contrast to most other chess AIs,[[AI]]s is written in the [[Python (programming language)|Python]] language and focuses more on fun of play than raw strength. For more advanced users, PyChess allows for virtually any other external chess engine to be used with it.<ref>{{Cite web |title=About PyChess |url=https://pychess.github.io/about/ |access-date=25 August 2021 |website=pychess.github.io}}</ref>

== History ==

Development on |PyChess datewas =started by Thomas Dybdahl Ahle in 2006, and the first public release was sent out later that year.<ref>{{Cite web |date=13 September 2006 |title=Pychess 0.2 |url=http://gnomedesktop.org/node/2758}}</ref> The release contained the bare minimum of features to play a game of chess, and was backed only by the [[GNU Chess]] engine.

In the end of 2006, PyChess was close to become a part of [[GNOME Games]], which were holding a usage survey of aspiring new games to include in the suite.<ref name="gamesplan">{{Cite web |date=3 September 2006 |title=GNOME Games Plan for Included Games |url=http://live.gnome.org/GnomeGames/NewGamesPlan |date=3 September 2006 |deadurlurl-status=unfit |archiveurlarchive-url=https://web.archive.org/web/20060903141629/http://live.gnome.org/GnomeGames/NewGamesPlan |archivedatearchive-date=3 September 2006 }}</ref> Being nearly just started at the time, it lost to the more established [[glChess]], which managed to fix its hardware accelerating dependency before the end of the trial.<ref name="gamesplan" /><ref>{{Cite web |last=Ancell |first=Robert |date=15 September 2006 |title=glChess...

PyChess has grown steadily since then, with increasing year-to-year development activity, and would cost more than $500,000 to develop today in terms of the man-hours required to develop such a codebase.<ref>{{Cite web |date=9 July 2011 |title=PyChess at Ohloh |url=https://www.ohloh.net/p/pychess |access-date=29 June 2011 |archive-date=16 October 2012 |archive-url=https://web.archive.org/web/20121016025450/https://www.ohloh.net/p/pychess |url-status=dead }}</ref>

== Aims ==

According to the PyChess website:

{{quote|The goal of PyChess is to provide an advanced chess client for [[Linux]], and do that with a nice and efficient [[user interface]] in line with the GNOME Human Interface Guidelines. The client should be fun and exciting to those new to chess -– who just want to play a short games to procrastinate their work -– as well as those who want to utilize their computer for further enhancing their play.<ref>{{Cite web |title=PyChess at GiHub Project Hosting |website=[[GitHub]] |url=https://github.com/pychess/pychess |access-date=10 July 2011}}</ref>|title=|source=}}

The PyChess project puts heavy emphasis on simplicity, trying to avoid the complicated [[user interfaces]] of [[XBoard]] and [[BabasChess]]. This implies adding new features slowly, so they can be integrated in the overall usage scheme, and make things "just work". At the same time the project strives to contain most of the features known from major Windows chess clients such as [[Chessbase]] and ''Aquarium'' by [[ChessOK]].
