Opening tree of any chess player

Enter a Chess.com or Lichess username to explore every opening the player chooses as White and as Black, move by move, with how often each move was played and how it scored.

What the opening tree shows

  • Every move the player chose from each position, with arrows on the board showing how often each one was played.
  • The number of games and the win, draw and loss split for every line.
  • Filters by color, time control, period and source (Chess.com, Lichess or over-the-board), and a Stockfish evaluation of the current position.
  • A PGN export of the games behind the tree.

Questions

What is an opening tree?
An opening tree gathers a player's games and merges them move by move. From the starting position you see every move the player chose, how many games went that way and how they scored, then the replies, and so on. It shows a repertoire as the player really plays it, not as a book says.
How do I see the opening tree of a Chess.com or Lichess player?
Pick Chess.com or Lichess, type the username and click Show opening tree. You land on the player profile, in the Repertoire section: choose White or Black, then click the moves on the board or in the list to go deeper. The arrows show how often each move was played from the current position.
Is it different from the Chess.com or Lichess opening explorer?
The Chess.com and Lichess explorers show what everyone plays, from master or online databases. This tree shows one player's games only, so you see their own choices and results. It works for any account, yours or an opponent's, and you can filter by time control, period and source.
Can I see the openings of FIDE players and their over-the-board games?
Yes. Search the player by name in the FIDE player search: their profile has the same Repertoire section, with over-the-board games from tournaments and the games of their linked online accounts.
How do I use it to prepare against an opponent?
Look up your next opponent, check which lines they play most and where they score badly, and prepare those positions. For a full plan, a hunting analysis compares their repertoire with yours and points to the openings where your strengths meet their weaknesses.
Is it free?
Yes. The opening tree is free and needs no account. The first visit of a new account can take a few seconds while we download its games.
