Stonksfish

A fast and simple chess bot written in Rust.

Play me on Lichess.

How to run

RUSTFLAGS="-C target-cpu=native" cargo run --release

Dependencies

The bot uses the Chess crate for keeping track of the game state as well as fast move generation during search and evaluation. For communication with Lichess APIs, the Licheszter crate is used.

How it works

The bot listens for events from Lichess and responds accordingly.
