Free internet chess toolkit software for linux

Internet Chess ToolKit project is a Java library for chess with PGN, FEN, SAN, and ICS (FICS, ICC) support.
Internet Chess ToolKit is a Java-based set of libraries and widgets useful for performing common tasks such as reading SAN (internationalized), FEN, PGN, generating legal moves, and connection to Internet Chess Servers (FICS).
The purpose of the Internet Chess ToolKit is to provide an extensible library to facilitate the development of internet server clients, bots, training programs, peer-to-peer players, and and various other programs useful for the game player. The library was designed with a high level of abstraction and utilization of object oriented design patterns to make it extensible; The model set up should allow for implementations of many games besides Chess, which is the main focus of this library.
Such other games might include chess variants like BugHouse, or completely different games like scrabble and the Chinese game of Go. Another goal of the library is ease of use. A lot of effort has gone into comprehensive documentation and providing sensible names for methods, as well as providing many convenience methods.
Main features:
- FICS support (limited)
- legal move generation.
- game history with variation support (alternative move suggestions).
- move comment support in text and Numeric Annotation Glyphs (NAG).
- Standard Algebraic Notation (SAN) read/write support (internationalized for presentation in 16 languages).
- Portable Game Notation (PGN) read/write support (including move variations, and FEN).
- Forsyth-Edwards Notation (FEN) read/write support.
- True MVC structure with board displays driven by game model events.
- Command-line Board display (GUI to come).
- Well documented. Sample code also provided.
Enhancements:
- Limited FICS support style12, match request, kibitz, whisper, say, tell, channel tell, shout, c/t/-shout, emote, move list, pin, gin, seek ads, seek remove, seek clear, game results
- Timeseal support
- XSLT java code generation for ICS events
- Sample ICS Client
- PGN bugs fixed

Five Chess is a connect-five board game. Five Chess is released under the terms of GNU General Public License version 2.

WT Toolkit is a JavaScript toolkit that makes writing rich, robust, reliable AJAX applications as easy as writing desktop applications.
Instead of being yet another hack of making AJAX "barely work", WT Toolkit is designed to be highly object oriented, resistant to memory leaks, and comes with an intuitive event handling system modelled after the signal-slot system from Qt.
Main features:
- GUI Widgets
- Vector Graphics
- AJAX Forms and RPC
- Signal-Slot Event System
- Resistant to Memory Leaks

Python chess module project is a Python chess move adjudicator module.
Python chess module does not know how to play chess, but does understand the rules enough that it can watch moves and verify that they are correct.
It features high abstraction, understands various notations (including algebraic, long algebraic, and standard algebraic notation), does disambiguation, and supports saving and loading the state of a game.
Main features:
- high abstraction
- understands various notations, including algebraic, long algebraic, and standard algebraic notation (as in PGN); does disambiguation
- supports saving and loading of the state of a game
- not a trivial move processor; understands the intracies of the game
Enhancements:
- Bug with en passant moves fixed.

Brutal Chess project features full 3D graphics, an advanced particle engine, and several different levels of intelligent AI, inspired by the once popular "Battle Chess" released by Interplay circa 1988.

DHTML Windowing Toolkit is a cross-browser JavaScript library for the creation of inline DHTML windows to contain content; windows that can be opened, closed, moved, and resized much like native windows.
Enhancements:
- Window objects can be created with the following features: open, close, minimize, restore, move, and resize.
- The following browsers are supported: Microsoft Internet Explorer, Mozilla Firefox, Opera, and Konqueror.
