Om detta tillägg
The extension opens its own analysis page — it does not overlay chess.com or any other site — and runs the
engine inside that page. Load a game and every move is graded; step through it, or stop anywhere and play your
own line to see where the alternative would have gone.
engine inside that page. Load a game and every move is graded; step through it, or stop anywhere and play your
own line to see where the alternative would have gone.
- Whole-game review that classifies every move with an Expected Points model, running across a pool of engines.
- Real opening-book classification (
Book) from an offline ECO database, not a guess from move numbers. - Terminal positions decided by the rules — checkmate, stalemate and draws are scored directly instead of
being handed to the engine. - Evaluation bar and timeline scrubber, in pawns or expected points.
- Interactive what-if play from any position in the game, including underpromotion.
- An unbounded move tree — every alternative you play becomes a variation under the move it branched from.
- Live MultiPV analysis of the position on the board, with a best-move arrow.
- Board and piece themes, board flip, and a reset that drops back to the reference line.
- Trap finder — moves that are sound for you and that opponents at your rating tend to
answer badly, found by crossing the Lichess opening explorer with the local engine.
- PGN paste, or a custom start FEN.
- Player Elo picked up from the PGN tags (
WhiteElo/BlackElo) when they are there. - One-click import from a chess.com archive.
