Chess Computer

A chess engine written in Rust.

Features

• Bitboard-based board representation
• Full legal move generation (castling, en passant, pawn promotion)
• Check detection
• Draw detection: stalemate, insufficient material, threefold repetition, fifty-move rule
• FEN import
• Zobrist hashing for position tracking

Usage

Run the game from the terminal:

cargo run

Moves are entered as two squares separated by a space (e.g. e2 e4). For pawn promotion, append the piece type as a third argument (e.g. e7 e8 q).
