corman

A chess engine written in Rust, built for fun in my free time.

How it works

The engine uses a bitboard-based board representation and searches with alpha-beta minimax. A few things it does:

• Move ordering via MVV-LVA to get better alpha-beta cutoffs
• Quiescence search to avoid the horizon effect on captures
• Null move pruning to speed up the search
• Transposition table with Zobrist hashing to avoid re-evaluating the same position
• Parallel search at the root using rayon
• Static evaluation based on material, piece-square tables, and attacked squares

It uses UCI protocol, so you can plug it into any UCI-compatible GUI or lichess-bot.

Building
