Free xboard 4.2.7 software for linux

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.

Pos is an experimental chess program based not on the Shannon algorithm, but on several others. Pos is not a brute force system.

The algorithm used is determined by a genetic (evolutionary) algorithm.

How to run it?

In a terminal

When using the SUN Java 5.0 runtime environment, start it with "java -Xmx384M -jar pos.jar".

Xboard/WinBoard

The program should now fully support xboard/winboard. Start it with commandline "java -Xmx384M -jar pos.jar --io-mode xboard".

For example: xboard -firstChessProgram "java -Xmx384M -jar pos.jar --io-mode xboard"

Tiffanys project is a Java chess engine, including a Swing gui and Win/XBoard support.
It supports the PGN / FEN format. Tiffanys also contains a XBoard / Winboard interface.
Main features:
- Swing GUI
- PGN / FEN Support
- XBoard interface
- Knows all basic rules (including Castling, EnPassant and Pawnpromotion)

QiPan project consists of the reference implementation of the CXBoard communication protocol.
QiPan is the reference implementation of a cxboard compliant interface program.
CXBoard is a communication protocol, modeled after XBoard and UCI, used for communication between Chinese Chess engines and interfaces.
Enhancements:
- This release contains new pieces and additional features that make it nicer to use and able to connect to 3rd party engines.

ics.el project is an Emacs mode for internet chess server interactions.
ics.el is a comint based Emacs major mode for handling the text portion of communications with internet chess servers such as FICS and ICC.
It is written in Emacs-Lisp and works best in conjunction with a graphical interface such as Xboard.
It handles colour highlighting and "buttonisation" (making certain portions of text active so that, for example, you can challenge opponents with a single mouse click) as well as command recall and editing and automation of commands based on regexps seen in the ICS output, all highly customisable using Emacs lisp.
Enhancements:
- added a require for overlay. This is part of the fsf-compat XEmacs package.
- added escapes into "----" and "++++" parts of regexps since not escaping them broke XEmacs version.
- added test for XEmacs into function tracing devel option
- changed the connection mechanism slightly to use a different variable ics-interface-with-helper-args when CONNECTMETHOD in ics-servers-alist is non-nil. This allows a different xboard commandline to be used if there is a timestamp/timeseal program available, rather than the same commandline with telnet for the helper program (which doesnt work for me anymore under Mandrake Linux 8.0 - I get a connection closed right before the password is prompted for).
- updated the default ics-servers-alist variable for new IP addresses and the BCF server and chess.net
- Fixed wholist buttonisation regexp to recognise "&" between rating and handle.
- Several fixes by John Wiegley to prevent ics.el from breaking other comint based modes - ics.el now uses local hooks instead of polluting the global comint hooks.
- Added support for running the interface program (e.g. xboard) under gdb in the ics sessions. The variable ics-gdb-interface controls this.

Slibo project is a chess interface and engine for KDE.

Slibo aims to be a comfortable replacement for the xboard chess interface, written for OpenGL and KDE.

It uses the xboard protocol and can be used with common chess engines like crafty or gnuchess, but it provides its own chess engine too.

Though its designed to be easy to use for the new chess player, it supports playing multiple games the same time, or anaylzing PGN files with multiple engines.

miniCHESS is a chess game WindowMaker dockapp.

miniCHESS was born out of boredom. I warn you... if your a chess enthusiast and play a lot then please use xboard or some other chess gui.

Even though miniCHESS has that kinda cool factor, it does get hard on the eyes. I like using miniCHESS for games in which Im in no hurry to finish and go on for a couple days.

Sorry but miniCHESS has no save/restore features yet.

Usage:

miniCHESS has a variety of options:

-h help
-t play text game (def = mouse game)
-r more random moves by the engine
-a hard, engine will also think on your time (def = no)
-d n max search depth used by the engine (def = 29)
-c n max time the engine gets to make a move (def = inf)
-T n size of the transposition table (def = 150001)
-C n size of the cache table (def = 18001)
-k #color background color for a checkmated king (def = #ff0000)
-b #color background color for the black pieces (def = #000000)
-f #color foreground color for the black pieces (def = #ffffff)
-1 #color color for the dark squares (def = #c8c365)
-2 #color color for the light squares (def = #77a26d)

If you specify a search depth (-d) to (say) 4 ply, the program will search until all moves have been examined to a depth of 4. If you set a maximum time (-t) per move and also use the depth option, the search will stop at the specified time or the specified depth, whichever comes first.

Gnuchess is a cpu hog while its thinking. Be aware. When the hard option (-a) is specified then the engine thinks all the time and pins your cpu.

Also gnuchess can be a memory hog. Specifying the size of the transposition and cache tables will modify the memory used. See the memory usage excerpt from the gnuchess FAQ below.

White piece colors are the reverse of what is specified for the black pieces.
