While the -library does know all legal moves, there is no "thinking" module. For -this, you must download one of the publically available chess engines, -such as gnuchess, crafty or phalanx. You will find all of these -sufficiently challenging, I'm sure. Once they are installed, chess.el -will use them, provided the locations of the binaries is on your PATH. - -John Wiegley <johnw@gnu.org> +chess.el is an Emacs Lisp library and several clients on top of the underlying +library functionality for performing various activities related +to the game of chess. +You can play against an external chess program such as gnuchess, +crafty, phalanx or sjeng. All of them are publically available, +and chess.el will automatically detect which one +you have installed, provided they have standard executable +program names, and are in a located in a directory which +is part of the PATH. See the customisable variable +`chess-default-engine'. + +You can also play against another human or computer over the internet +(through a direct Emacs-to-Emacs connection, or +on one of the Internet Chess Servers like freechess.org or +chessclub.com), or even against a very simple chess thinking +module implemented in pure Emacs Lisp. + +chess.el also provides a mode for editing Portable Game Notation (PGN +files. + +To improve your chessaility, you might also like to have +a look at chess-puzzle, which allows you to solve +chess puzzle collections (in PGN or EPD format) against +one of the engines you have installed. + +HISTORY + +chess.el started out as a single file project with +version 1.0 by John Wiegley <johnw@gnu.org>. Version 2.0 is a major +rewrite and reorganisation of the original code, also done +by John Wiegley. In the end of 2003, John did not +have a lot of time to finish all the various aspects of version 2.0, +and maintainership was given to Mario Lang <mlang@delysid.org>. + LAYOUT |
