GNU Chess lets most modern computers play a full game of chess. It has a plain terminal interface but supports visual interfaces such as XBoard.
Version 6.0.3 is the current release of GNU Chess. Version 6 shares some code with version 5 and it keeps backwards compatibility to a large extent.
The first version of GNU Chess was written by Stuart Cracraft. Fabien Letouzey is the primary author of GNU Chess 6, which is based on Fabien's chess engine Fruit 2.1.
Version 6.0.3 is primarily a bug fix release. What is fixed in v6.0.3:
- If the program is in manual mode, an 'undo' action will keep it in manual mode.
- 'configure' and Makefile.in have been generated with autoconf 2.69 and automake 1.13.
- Remove some unused code.
The primary documentation is the GNU Chess manual, which you can find in several formats.
