GNU Chess

GNU Chess is a chess-playing program. It can be used to play chess against the computer on a terminal or, more commonly, as a chess engine for graphical chess frontends such as XBoard.

The current version is 6.2.5. The 6.2.x series includes the following new features with respect to previous 6.1.x:

• "Tighter connection" with XBoard by means of an engine file and a logo, as expected by XBoard (>= 4.6.0).
• A simple man page based on help2man.
• Additional translations.
• Some minor fixes.
• Some minor commands.
• Command history enabled by readline.
