Chess Engines

Chess engines are programs capable of playing a game of chess.

eboard supports the xboard protocol for interface/engine communications, version 2. Most chess engines comply with this protocol, which became the way it is today in an ad hoc way. eboard extends it to send Crafty-specific commands to Crafty and to work with GNU Chess 4.x, which has some idyosyncrasies.

This page is a summary of the engines that have been tested with eboard. Version numbers in parenthesis refer to the version or range of versions actually tested.
