Chess Engines – Tim Mann

Are you writing a chess engine that you want to have work with XBoard and/or WinBoard? Are you writing a chess user interface or other tool and want it to work with the same engines that work with XBoard and WinBoard? Here are some pointers.

First, read the Chess Engine Communication Protocol document, which describes the protocol that XBoard and WinBoard use to communicate with engines. This document is also included with the XBoard/WinBoard source code, available through the GNU XBoard project page.

Second, go to the WinBoard Forum and ask the folks there for help and advice if you need it.

There are literally hundreds of chess engines (programs that play chess) that work with XBoard and/or WinBoard. I gave up on keeping an updated list years ago, and the old list that used to be here contained so many dead links that I have deleted it.

Some good places to find out about chess engines that you can use include Leo Dijksman's web site and the WinBoard Forum. Also see the other links on my Chess Web Sites page.

ExaChess Downloads

ExaChess Lite

ExaChess Lite, the free reduced-feature version of ExaChess, includes the ExaChess (Pro) full user documentation.

ExaChess (Pro) is not available for general download. Please try ExaChess Lite as a demo version. See Ordering for information on how to order ExaChess.

If you are a registered user of any prior version of ExaChess, then ExaChess 4 is a free upgrade (electronic delivery option only). Contact Exant Software (the publisher of ExaChess) for download information.

ExaChess 4 supports UCI chess engines, and includes the strong Fruit engine. There are dozens of strong UCI engines available that run under Windows, but only a small fraction make it to the Mac. For surveys of available engines see Chessville Chess Engine Update or Top UCI Chess Engines. For a current rating list of engines, see the IPON Rating List.

The following is a selection of strong free and commercial UCI engines for the Mac:

Various freeware and commercial chess fonts are now available on the Internet.
