Free chess game software for linux

Chess::Game is a class to record and validate the moves of a game of chess.

SYNOPSIS

use Chess::Game;

$game = Chess::Game->new();
$clone = $game->clone();
$move = $game->make_move("e2", "e4");
$move_c = $clone->make_move("e2", "e4");
$true = ($move->get_piece() ne $move_c->get_piece());
$move = $game->delete_move();
...
while (!defined($result = $game->result())) {
# get a move
$move = $game->make_move($sq1, $sq2);
if (!defined($move)) {
print $game->get_message();
}
}
if ($result == 1) {
print "White wins!n";
}
elsif ($result == 0) {
print "Draw!n"
}
else {
print "Black wins!n";
}

The Chess module provides a framework for writing chess programs with Perl. This class forms part of that framework, providing move validation for all moves recorded using the Chess::Game class. The Game contains a Chess::Board, 32 Chess::Pieces and a Chess::Game::MoveList that contains a series of Chess::Game::MoveListEntrys that record the exact state of the game as it progresses. Moves can be taken back one-at-a-time to allow for simple movelist manipulation.

ChessX is a free Open Source Chess Database for Linux, Windows, and Mac OS X. The project uses Qt library to create modern, portable graphical interface. Current development is aimed at providing full featured PGN database. Afterwards we will add more flexible native format.
History
The project was started after development of Scid halted and contact with the author was lost. Initially, ChessX was to be a community maintained version of Scid called "New Scid". However, after some initial development, it was decided to break away from the old code so that new ideas and modern interface can be implemented.
Main features:
- Multi-platform. Supports Linux, Microsoft Windows and Mac OS
- Read-only support for PGN Files
- Work with multiple databases simultaneously
- Browse games
- Navigate through game, including variations
- Copy/Paste FEN/PGN
- Enter moves, setup board position
- Basic header search (click on columns in GameList header)
- Player database with picture support

This is an adapted, improved version of the popular javacave game, written in QtRuby.

Installation:

download
chmod +x snake(gl).rb
run it.

Chessweb is a J2EE chess game Website. It is a pure Java servlet implementation of a two-player chess game.

Two players log into the Web site, see an image of the current board in their browser, and make their moves.

The differentiating features of chessweb (e.g. versus WinBoard / XBoard) is that its an extremely lightweight implementation written completely in Java (nothing more than an app server and browser is required).

Furthermore, the client end is DHTML only, and verified to works with FireFox 1.0.6 and IE 6.

Tonic Chess project is an online chess software.

Tonic is a graphical interface for playing online chess. It is based on Jin.

From now on Tonic is really open source software (and free as in libre as well) - I managed (I had some problems last time I tried) to import source to cvs sourceforge repository. It is a bridge2 release source with few little modifications. You can read how to get it from cvs here. If you are impatient pastenenter in console:

cvs -d:pserver:anonymous@tonic-chess.cvs.sourceforge.net:/cvsroot/tonic-chess login

When prompted for password just hit enter. And then:

cvs -z3 -d:pserver:anonymous@tonic-chess.cvs.sourceforge.net:/cvsroot/tonic-chess co -P tonic

You should see a list of files downloaded from cvs repository. If you are a non-console user (i.e. Windows or Mac user) I recommend visiting this site. I myself use Linux for development. And Netbeans sometimes as you could figure out from examining the contents of tonic directory. So, enjoy the opensourceness of Tonic!

I uploaded new screenshot to Tonic project site. It is Tonic in Aero GTK engine tuxedo. Quite a peculiar engine imo, but you can use other GTK engines if you run Tonic in Java 6 aka Mustang (you know you can get it from here, dont you?) I test Tonic with Mustang and Ive problems with tray icon. After some searching Ive realized why Tonic crashed under Java 6 - the problem was tray.jar plugin and its dependencies - tray.so or tray.dll, so if you want to run Tonic on Java 6 move them away from theirs directory. Ive written a class for tray icon using new desktop API from Mustang, but it doesnt work as expected in KDE (tray icon is invisible) ; GNOME is better, but I have to work on the popup menu. Well, what could I say? Mustang is in beta stage, but it has some goodies to wait for (early splashscreen, access to tab component, ...).

Ruby Chess is a chess game implemented in Ruby using GTK2. Ruby Chess project has a good artificial intelligence that is heuristic-based and stochastic.

glChess is a chess game with 3D OpenGL graphics.

An open-source 3D chess program. It uses openGL and gtkglarea (from GTK+) for the rendering and is designed for use in unix.

It will soon be able to be played over network much like xboard can currently. It has tentative support for computer play. Playable against a human or against "crafty" AI.
