Inanis

UCI chess engine written in Rust, the successor of Proxima b, Proxima b 2.0 and Cosette. The project is written after hours, with the goal to reach a strength of 3000 Elo. Perfect as a sparring partner for other chess engines, since it was heavily tested using very fast games. Supports Syzygy tablebases, MultiPV, pondering and multithreading.
