Games::Chess Perl module represent chess positions and games.

SYNOPSIS

use Games::Chess qw(:constants);
my $p = Games::Chess::Position->new;
$p->at(0,0,BLACK,ROOK);
$p->at(7,7,WHITE,ROOK);
print $p->to_text;

The Games::Chess package provides the class Games::Chess::Piece to represent chess pieces, and the class Games::Chess::Position to represent a position in a chess game. Objects can be instantiated from data in standard formats and exported to these formats.

NOTATION

See Games::Chess::PGN for full details of the notations.

SAN

Standard Algebraic Notation. The modern international notation for chess games. For example,

1. e4 e5
2. f4 exf4
3. Nf3 g5

FEN

Forsythe-Edwards Notation. A compact representation for chess positions. FEN specifies the piece placement, the active color, the castling availability, the en passant target square, the halfmove clock, and the fullmove number as six fields separated by spaces. For example, the opening position is described in FEN as follows:

rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1

PGN

Portable Game Notation. A notation for chess games, including the moves, commentary, variations, and metadata such as the players, the event, the round number, and the date of the match. For example,

[Event "F/S Return Match"]
[Site "Belgrade, Serbia JUG"]
[Date "1992.11.04"]
[Round "29"]
[White "Fischer, Robert J."]
[Black "Spassky, Boris V."]
[Result "1/2-1/2"]

EPD

Extended Position Description. An extensible notation based on FEN. Intended for data interchange between chess-playing programs and for the construction of opening databases. Not used by Games::Chess.

gnome-chess is chess game, a graphical user interface for playing chess.

It works with chess programs and chess servers - it is also a PGN viewer. For chess programs, it works best with the chess engine crafty (ftp://ftp.cis.uab.edu/pub/hyatt) but most features should also work with GNU Chess (ftp://ftp.gnu.org).

You can use the "first chess program" option to choose the computer engine you want to play against.

E.g. try "gnome-chess --fcp crafty" or "gnome-chess --fcp gnuchessx"

You can use the --ics* options to choose the server and pick user name and passwords.

E.g. try "gnome-chess --ics --icshost freechess.org"

Five Chess is a connect-five board game. Five Chess is released under the terms of GNU General Public License version 2.
It was initially developed from a qt Tic-Tac-Toe example.
Main features:
- 4 ways to play -- Human vs Human, AI vs Human, Human vs AI, AI vs AI
- 6 board sizes available -- 9X9 to 19X19

- Not so smart AI

Java3D chess project is a Java applet that allows you to play chess.

Java 3D Chess is a chess program with uses Java 3D. You can play the game on any computer capable of using Java.

You can play Java 3D Chess agains yourself or a friend (on the same computer).

Maybe inthe near future you can play against other as well.

Dreamchess is a XBoard-compatible 3D chess interface and engine.
DreamChess is an open source chess game. Our primary target platforms are Linux, Windows, Dreamcast and BeOS. DreamChess features 3D OpenGL graphics and provides various chess board sets, ranging from classic wooden to flat figurines.
A moderately strong chess engine is included: Dreamer. However, should this engine be too weak for you, then you can use any other XBoard-compatible chess engine, including the popular Crafty and GNU Chess.
Other features include on-screen move lists using SAN notation, undo functionality, and savegames in PGN format. In future releases we plan to add support for time controls, audio, network play, more visual effects such as reflections and shadows, and 3D animated pieces.
Enhancements:
- 3D OpenGL user interface (XBoard-compatible).
- A variety of chess sets, including classic wooden and flat figurines.
- Moderately strong chess engine.
- Savegames in PGN format.

Emacs Chess is an object-oriented library written in Elisp for manipulating chess objects (games, plies, positions, etc.), and for displaying them.
Main features:
- Emacs Chess is also an object-oriented library for manipulating chess objects (games, plies, positions, etc), and for displaying them. It supports a wide range of engine objects to use as move sources. This what allows chess.el to act as a chess client.
- chess-announce.el announces your opponents moves verbally, such as "knight takes at f4"provided you have "festival" installed.
- chess-sound.el is similar to chess-announce, but uses specific WAV files for each sound used. It takes up much more disk space, but is nicer to listen to. Available in English only at the moment.
- chess-irc.el provides a tiny IRC bot, allowing you to play games over IRC so long as your opponent enters moves in short algebraic notation. If they dont have chess.el, all they need is a regular chessboard, and a knowledge of SAN (short alegebraic notation).
- chess-ics.el lets you to play on Internet Chess Servers, using chess.el as your chessboard display (which means chess-announce works with it, etc). It has only been tested with FICS so far.
- chess-crafty.el, chess-gnuchess.el and chess-phalanx.el let you play against the Crafty, Gnuchess and Phalanx engines.
- chess-random.el will create Fischer Random positions to play against. Note that this feature only really works against opponents who are also using chess.el. Simply type "S" in the chessboard display buffer to setup a Fischer Random starting position.
- chess-network.el lets you play against other chess.el users directly, over a single open port on the server side. To be a server, you must have "netcat" installed, or be using Emacs 21.3 or higher (which supports server side network sockets). To be a client, all you need is Emacs 21.1 or higher.
- chess-link.el lets you tie two engines together, so that events from one are responded to by events from another. This can let you run a chess bot on your computer over any of the transport, or you can use it to pit two computer chess engines against each other.
- chess.el can even export chessboard display to other X servers, allowing you to play against people in your meeting room, even if they dont have Emacs installed!
Enhancements:
- This maintenance release includes several bugfixes.
