Open Source ChromeOS Chess Engines

Redqueen is an UCI (Universal Chess Interface) only compatible chess engine written in C++.

This library is an attempt to create a flexible chess engine using the Java programing language. The main diference than others chess engine's is that it is only a library, and it can be attached to any program, including a web application. If you are interested to contribute please contact me.

Frittle is an open source amateur Java Chess Engine that supports the XBoard/WinBoard Chess Engine Communication Protocol (version 2).

An open source chess engine in C, released under the GPL. Compatible with the XBoard and UCI interface protocols to link to a GUI or other chess arbiter.

IMPORTANT: I renamed the project to cengix (chess engine no. x). See http://code.google.com/p/cengix. IMPORTANT: yacen is not in any way related to the YACE chess engine. The similar name was a mistake. To avoid confusion, I will rename my project soon and provide a link to the new site then. yacen is a simple chess engine with main focus on understandability of code and mechanisms rather than on pure performance. It is completely written in ANSI-C using nothing more than the standard library and thus is very portable and easy to compile on almost every platform. yacen uses the common UCI interface to communicate with any compatible GUI. NOTE: yacen is currently in pre-alpha status. This means that there is only source code available which is far from complete and thus cannot be compiled to a working binary yet. A more complete source code and first binaries for Linux and Windows will be available when the project reaches alpha status.

This is UCI Chess Engine writen in Java. Since version 1.4 (inclusive) the project was moved to https://github.com/bagaturchess/Bagatur

An easy to understand chess engine.

A chess application in order to play against computer or to play with another human. No network playing is planned (no FICS). This program uses the Carballo Chess Engine in order to check moves, and the Stockfish engine (that you must download on their website) in order to generate the computer moves.

Extensive Java chess database libraries. Native game database, native position database, pgn database reader.

Yet another chess engine.

A chess engine to use with chess software or chess servers written completely in Java.

Java Program of a machine which plays chess: it recognizes the chessboard, the position, the move of the opponent, and asks an external Chess Engine to reply to the opponent move. it is connected to a real robot which has an arm to manipulate the pieces.

KCChess -- yet another xboard-compatible chess engine.

KMT Chess is a chess engine. It supports Winboard Chess Engine Protocol and can be used in combination with Winboard or Arena user interfaces. KMTWinboard package includes WinboardX interface and a opening book, providing a much better user experience.

"Mentally Challenged" is an XBoard/WinBoard compatible chess engine written in Java.

The Minerva Chess Engine is an artificial chess opponent. It learns as it plays and can be distributed across multiple computers for increased power.

This chess engine is the result of the project work 2013 at the University of Applied Sciences, study programme Applied Informatics. The target was to write an engine that is able to play chess with the official FIDE rules. At the moment, the engine chooses the first-found valid move instead of the best move. Other java classes should be fine. - shout-out to Mediocre Chess

You are given a chess graphical interface, with drag and drop functionnalities (or other interaction mode), board flipping, and some pieces/cells sets given. Then, you have some callbacks methods in order to validate moves from your chess engine and to update them to your chess engine.
