Overview

Mess is an open source, UCI-compliant chess engine. Mess is not a complete chess program and requires an UCI-compliant chess graphical user interface(e.g. XBoard with PolyGlot, Scid, Cute Chess, eboard, Arena, Sigma Chess, Shredder, Chess Partner or Fritz) to be used comfortably.

Mess's code structure is extremely modular and thus it may be used as a library for developing chess engines in go. The ./pkg directory will contain all the packages that are available for use publicly.

Mess on Lichess

The MessChessEngine Bot is currently hosted on my laptop, and therefore might not always be online. The most reliable way to play against mess is to download the engine and use it with an UCI-compliant graphical user interface.
