Open Source C Chess Engines for Mac

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.

Witz is a chess program that is designed to work with a Winboard interface.

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.
