A UCI chess engine written in Rust.
You can use any chess UI that knows how to talk to engine with UCI. I use en-croissant, Chessifier (now Pawn Appetit) works as well. Play it on Lichess via https://lichess.org/@/DuckChessEngine!
cp .env.example .env
# Edit .env with your Lichess bot API token
docker compose up -dThe container builds the engine from source, bundles it with lichess-bot, and runs in the background. Use docker compose logs -f to watch output, docker compose down to stop.
The engine supports an opening book (PGN). Set the path with the UCI option BookPath and enable OwnBook (default: true). When the current position is in the book, the engine plays a random book move. Example: opening_books/8moves_v3.pgn (from Stockfish books).
