Changelog

An eval bar beside the board.

• Added Eval bar: a white/black advantage strip to the left of the board, your colour at the bottom, following the board when you flip it. It holds the last evaluation dimmed while your opponent moves rather than blinking out. On by default; toggle it in the popup. The number stays in the pill on the board.
• Fixed The popup paints from cached account data immediately instead of waiting for the service worker to wake and for tab queries to finish.

Host access is limited to the chess sites we actually run on.

• Fixed The extension no longer asks for every chess.com and lichess subdomain over http. HTTPS on www/apex only. Overlay behaviour is unchanged.

Lichess games no longer spam Chrome with fake move-list errors.

• Fixed Lichess hashes its move-list tags on every deploy, so the extension thought the move list was broken even when PGN and accuracy were fine. Chrome files that warning as an error. Capture still uses SAN fallback; the Errors panel stays quiet unless the board itself is missing.
• Added Discord icon in the extension popup, next to the on/off switch. Opens the Chess Wizard server.

Finished games get an accuracy score from the local engine.

• Added When a game ends, the extension walks the PGN with the bundled Stockfish (depth 12) and stores your accuracy. Same formula as the site. A later cloud analysis still overwrites this number if it runs.

Live-game PGNs capture moves again, not chess.com clock times.

• Fixed The extension was saving “3.3s 0.5s …” as the PGN because it read the whole ply row, clocks included. New games store SAN. Already-broken rows cannot be reconstructed from clocks; replay the game to recapture.

Sign in with Google. Game review links work. Analysis boards are not saved as games.

• Added Continue with Google on log in and create account. Existing email accounts with the same verified address are linked, not duplicated.
• Fixed Google-only accounts no longer ask for a current password in Settings when changing password or deleting the account.
• Fixed chess.com analysis, puzzles, and vs-computer boards are no longer saved as played games. Overlay still runs on those pages.
• Fixed Opening a game review no longer 404s. Reviews live at /games/chess.com/… instead of stuffing a colon into the path.
• Fixed The extension no longer reports a broken move list on chess.com/play/online before a game has started. Chrome was filing that warning as an error.

Rebuilt around Stockfish. Rebranded to Chess Wizard.

• Added Stockfish 18 (lite, single-threaded WASM) bundled with the extension.
• Added Multi-Move: one MultiPV search returning five ranked candidates, colour-coded by centipawn loss.
• Added Engine Strength slider, mapped to MultiPV search depth 1–20.
• Added Ctrl+Shift+Y toggles the overlay.
• Removed All remote engine providers.
• Removed Autoplay, weak-move injection, and the synthetic input patch — entirely, with no traces left behind.
• Fixed Evaluation sign convention: the score is now player-relative and correct when playing as black.
