shakmaty

A Rust library for chess move generation

crates.io docs.rs

Features

  • Generate legal moves:

```rust use shakmaty::{Chess, Position};

let pos = Chess::default(); let legals = pos.legalmoves(); asserteq!(legals.len(), 20); ```

  • Play moves:

```rust use shakmaty::{Square, Move, Role};

// 1. e4 let pos = pos.play(&Move::Normal { role: Role::Pawn, from: Square::E2, to: Square::E4, capture: None, promotion: None, })?; ```

  • Detect game end conditions: pos.is_checkmate(), pos.is_stalemate(), pos.is_insufficient_material(), pos.outcome().

  • Read and write FEN, SAN and UCI notation.

  • Supports all Lichess variants: Standard chess, Chess960, Antichess, Atomic, King of the Hill, Three-Check, Crazyhouse, Racing Kings and Horde. Provides vocabulary to implement other variants.

  • Bitboards and compact fixed shift magic attack tables.

  • Zobrist hash positions.

  • Probe Syzygy tablebases with shakmaty-syzygy.

Benchmarks

Simple perft of the initial position. No hashtables. i7-6850K CPU @ 3.60GHz.

| perft | 4 | 5 | | -------------------------------------------------------- | ------ | ------- | | shakmaty 0.16.0 | 1.0 ms | 24.1 ms | | jordanbray/chess 3.1.1 | 0.8 ms | 18.6 ms | | Stockfish 8 (x86-64-bmi2) | 4 ms | 33 ms |

It should be noted that Stockfish is not optimized for perft speed and also maintains additional data structures for evaluation. Newer versions of Stockfish put even less emphasis on this.
