How It Works
Stockfish Integration
XFChess uses the Stockfish chess engine, running as a separate process that analyzes positions and calculates the best moves.
UCI Protocol
The game communicates with Stockfish using the Universal Chess Interface (UCI) protocol, sending FEN positions and receiving move recommendations.
Adjustable Difficulty
Choose from multiple difficulty levels by adjusting search depth and thinking time, making the AI suitable for players of all skill levels.
Stockfish Process Spawning (Rust)
let mut child = Command::new(stockfish_path)
.stdin(Stdio::piped())
.stdout(Stdio::piped())
.stderr(Stdio::null())
.spawn()
.map_err(|e| format!(""Failed to spawn Stockfish: ", e))?;
