Technical details

chess.js validates legal moves, checks, castling, en passant, promotion, and game results. A browser-safe asm.js Stockfish build runs in a classic Web Worker, avoiding the cross-origin-isolation requirement of multithreaded WebAssembly engines.

Verification & limitations

Lint and production build checks passed locally. If the engine cannot load or answer, computer mode chooses a random legal move while local two-player play remains available; that fallback is not equivalent to Stockfish analysis.

Computer strength is capped for browser responsiveness. Clocks record elapsed time but do not enforce time controls. Online multiplayer, saved games, PGN import/export, sound, and drag-and-drop are not implemented.
