Free chess world software for linux

Hell World is a thrilling FPS adventure game which features excellent graphics, a dark atmosphere and an excellent scenario. Hell World game is designed to be a port of the Windows-only version of Hell World.
It is written using the openGL and SDL library and is developing for the last months by ironhell3.
The game starts from main.c There we call first two functions, sdl_init() and game_init() to initialise the sdl and game part of the game.After the succesfull initialisation of Hell World we loop in a while() function.Each frame we check the keyboard and mouse for events through keyhandler() and then render the game frames through loop().When we catch a done=true signal we quit the game.

mChess is a simple cross-platform email chess program.

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, ...).

BabyChess is a chess program. You can edit chess games, play chess on the internet, and play locally against engines.
BabyChess is distributed as free software under the terms of the GNU GPL.
Main features:
- Games between humans and/or engines can be played in the match window. XBoard engines are supported.
- The chess position editor lets you edit a chess position, and save it in FEN notation, as used by other chess programs.
- The chess game editor understands PGN notation.
- The game archive editor reads PGN files that contain any number of chess games. It displays a list of all games and lets you edit those games using the game editor.
- The ICS client connects you to an Internet Chess Server and lets you play games against human opponents.
- The "evaluator" of BabyChess is a chess engine that uses its own communication protocol. It is not an XBoard engine. This program is given a FEN position as an argument and analyzes the position. During the thinking process, information about the current best move and more is written.
- The game editor uses the chess evaluator to analyze chess positions.
- Internally, the evaluator uses 64 bit numbers even on 32 bit systems, meaning it is possible to analyze more than 2 billion positions on PCs.
- This program implements an XBoard chess engine. It uses the evaluator as a backend.
- In addition to the standard algebraic notation (SAN). French, German and Dutch notations are supported. Figurine notation is also supported, also the current fonts dont make it look good. New notations can be created.

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.

PicoChess project is a small chess program.

PicoChess will support one and two player games, as well as playing against itself. It can also load and save games, and export transcripts of games.

ChessTask project is a tool for generating chess tasks.

ChessTask is a frontend for easily creating chess tasks with LaTeX. The tasks are stored in a list which can be exported, either into a LaTeX input file, or into HTML files.
