Play chess (Wukong JS)

Built by Jeff Gilbert

Play chess in your browser against a strong computer. This app now uses Wukong JS, a lightweight JavaScript engine. It also uses a live Lichess opening book to follow real-world theory. You get hints, coaching notes, and a scoresheet for review—plus instant start, no sign-in, and no clutter.
