Cinder is a strong chess engine written in Rust from scratch. With a playing strength that is far superior to what humans are capable of, Cinder is primarily developed to play against other engines. It is regularly tested at the extremely short time control of 1s+10ms per game. The shorter the time control, the stronger Cinder tends to play.
Cinder implements the UCI protocol and should be compatible with most chess graphical user interfaces (GUI). Users who are familiar with the UCI protocol may also interact with Cinder directly on a terminal via its command line interface (CLI).

Cinder is an open source project and you're very welcome to contribute to this project by opening issues and/or pull requests, see CONTRIBUTING for general guidelines.
Building Cinder from source currently requires a recent nightly Rust compiler,
cargo-make, and cargo-pgo. To compile binaries optimized for various CPU architectures,
simply run cargo make --profile production cinder. The binary artifacts will be placed
under target/bin/.
