Super Chess Bot — Chess.com build

The standalone dist/chesscom.user.js build provides local Stockfish analysis and move automation for standard Chess.com player games. It uses the same controller integration and reliability limits described in the support matrix.

Install License

Install

  1. Install Tampermonkey or Violentmonkey.
  2. Install the Chess.com userscript.
  3. Open a standard player game, wait for Ready, then enable automation.

The standalone build includes Stockfish resources for standard chess. It does not claim Chess.com variant move support. For the multi-site build and Lichess notes, see the main README.

Features

  • Local Stockfish search in a web worker, with up to three candidate lines.
  • Instant 0 ms FEN-keyed premove engine with own-turn recapture chains, opening book replies, and opponent-turn multi-branch ponder table.
  • Standard opening-book choices, configurable move timing, and a scoresheet with PGN export.
  • Optional post-game report using a local engine estimate. The default is depth 18, adjustable from 10 to 26; analysis requires a finished game.
  • Asynchronous standard-chess Syzygy lookups for eligible positions with up to seven pieces. Results use a 256-entry cache keyed by full FEN. DTZ and DTM remain distinct, and a usable local search result does not wait for a tablebase grace period.
  • Stream Ghost Mode hides the panel and board overlays. Closed Shadow DOM provides UI encapsulation; it is not a guarantee of invisibility or undetectability.

Chess.com controller state can show that a move was applied locally. The current integration has no independent server acknowledgement, so local application is never described as server acceptance. See move confirmation provenance.
