Runs entirely in your browser. First analysis downloads about 44 MB of engine assets; the network is cached when browser storage is available. No positions are uploaded. This is an analysis board without live game clocks. “Sit” means wait for your partner. The advantage estimate compares searches from both teams; it is not a Stockfish pawn score or a measured win probability. Short searches can disagree.
