How this profile works

We read Chess.com’s public monthly archives, newest first, until we have your selected number of eligible games or have checked 24 available months. Variants, unfinished games, custom starting positions and unreadable move records are excluded. Filters apply to this imported sample.

Openings are matched against named positions in the Lichess opening dataset (CC0), including positions reached in different move orders. The deepest recognised position in the first 30 moves names the opening. Some unusual lines may retain a broader opening name.

Score is wins plus half of draws, divided by games. A low score is a reason to review those games; it does not prove an opening move was wrong. Opening practice suggestions use frequency and game results, with small samples labelled. The optional Stockfish check above evaluates your moves separately. Chess.com Game Review annotations are not imported.

Refresh imports to check for new games. Chess.com archives can update with a delay. About the Chess.com public API.

THE BOOKMOVE METHOD

A line worth remembering.

  1. Pick your practice. Search for an opening, choose its variation and pick White, Black or Random. Book lessons support 1–10 moves per side; extended lessons support 1–30.
  2. Learn one branch. Follow the highlighted move. The book plays the other side of your chosen variation, with the same replies each attempt.
  3. Try from memory. You get one optional idea hint per attempt, with no move or square revealed. Leaving the selected line ends the attempt and shows the expected move. A recognised alternative is labelled as another catalogue line.
  4. Make it stick. Retry, revisit the guided lesson, or keep playing against a simple practice opponent after reaching your target.

The original 152 book entries contain 116 distinct sequences over the first 10 moves. An additional Englund Gambit lesson covers the main queen-attack line. Some named variations share those moves and separate later. Their lessons are labelled as introductions when the full reference continues beyond the selected length. Different legal moves can be good chess and still be outside this memory exercise.

Opening references & credits

The 152 book entries use the first 10 full moves of every qualifying sequence in the Lichess opening dataset (CC0). Repeated names identify separate source references. The additional Englund Gambit lesson follows the 8.Nd5 variation in Ian Simpson’s published analysis, with original Bookmove explanations. The named sequences are opening references, not a promise that every move is best.

The original 30 extended lessons remain available. They cover a practical selection from Chess.com’s popular openings catalogue; popularity varies by rating and time control. Their later moves are illustrative middlegame continuations prepared with Stockfish.
