GNU XBOARD HOW TO
GNU XBOARD WINDOWS

Has a long and complicated list of commands.Allows chess engines act a bit independently such as they can auto-start pondering after a move.Allows users to play directly with chess engines without using chess GUIs.Designed to work without the need of having an extra thread for processing those commands.Has redundant commands for almost all chess tasks from old-time to now.Those pros and cons compared with UCI Pros Harm Geert Muller established a protocol Version 2 in September, 2009, also covering Chess Variants and different board sizes. WinBoard/XBoard protocol UML state diagram by Alessandro Scotti Version 2 It would be nice to make some major revisions, but then of course it would (at best) take a long time for the existing engines to convert over to the new protocol, so both would have to be supported, probably forever. Unfortunately, because the protocol was never really designed, but just grew out of documenting the existing communication with GNU Chess, there are still several bugs and deficiencies in it today. The document that exists now (chess-engines.html) evolved directly from the original email reply I sent to Shay. Over the years I received so many requests for this information that I was more or less forced into documenting and extending the ad-hoc engine protocol to support them.

I think the first person to ask was Shay Bushinsky, in November 1994.

Because the GUI and the chess engine are separate programs, several people thought of the idea of connecting their own chess programs in place of GNU Chess, and they began to email me asking how to do it. Originally, xboard and WinBoard were simply graphical user interfaces for GNU Chess, then for GNU Chess and Internet chess servers. Tim Mann in an Interview by Frank Quisinsky, April 2000 : While the Universal Chess Interface is somewhat more popular today, the Chess Engine Communication Protocol protocol is preferred by some because it allows greater flexibility for the engine (for instance, in pondering). Many other GUIs support the protocol, which is based on text commands, while requiring the engine to keep the state of the game internally.

A GUI supporting the protocol is known as XBoard or WinBoard, being for Unix (Posix) or Windows operating systems, respectively.
