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.
XBOARD CHES HOW TO
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.
XBOARD CHES WINDOWS
