Game review, without the daily limit

How it works

1. 1

   Load the game

   Pick one from your Chess.com or Lichess history, or paste the PGN from any site or tournament.

2. 2

   Let the engine work

   Stockfish evaluates every position with two lines each, so the review knows not just the best move but the second best.

3. 3

   Start with the key moments, then step through the moves. Each grade links to the position so you can see the alternative.

• Key moments

  The handful of moves that actually decided the game, ranked by the swing in winning chances.

• Evaluation graph

Three depths, one honest trade-off

Depth is the number of half-moves the engine looks ahead along its main line. Each extra ply costs more time, but grades stabilise quickly: a move that is a blunder at depth 12 is almost always still a blunder at depth 20. Use Deep when a specific position matters.
