OpeningTree.com<\/strong> is a free chess opening analysis tool that turns your games into an interactive opening tree so you can finally see what you actually play and how well your openings perform. By pulling games directly from Chess.com, Lichess and PGN files, it gives you a single, clean view of your repertoire and results, and makes opening preparation much faster and more targeted.<\/em><\/p>\n\n\n\n

What Is OpeningTree.com?<\/h2>\n\n\n\n

OpeningTree.com<\/a><\/strong> is an online platform that aggregates your games and displays them as a branching opening tree, with statistics at every move and variation. Instead of guessing which lines you play most often, you get objective data on move frequencies, scores and critical junctions, based on your own games or the games of any public user you choose.<\/p>\n\n\n\n

The tool works directly in your browser and is completely free to use: you paste a Chess.com or Lichess username, or upload a PGN file, and OpeningTree builds a full tree of positions and continuations. This makes it ideal for club players, coaches and streamers who want a practical, data\u2011driven way to study openings and prepare for specific opponents without needing ChessBase or expensive databases.<\/p>\n\n\n\n

Openingtree.com has the right to be considered one of the best online tools to study chess.<\/figcaption><\/figure>\n\n\n\n

    These features make OpeningTree.com much more than a simple PGN viewer; it becomes your personal opening scout, showing you how your practical repertoire behaves under real\u2011game pressure.<\/p>\n\n\n\n

    How OpeningTree.com Works<\/h2>\n\n\n\n

    When you enter a Chess.com or Lichess username, OpeningTree connects to the platform\u2019s API and downloads a large number of your games, often more than you would comfortably load in a normal game viewer. It then groups them by move sequence and builds a branching tree where each move shows how many times you played it and your score from that position.<\/p>\n\n\n\n

    You can click through the moves on the board or in the move list to drill down into specific lines and see your personal performance in common openings such as the Sicilian, the French Defense or the Queen\u2019s Gambit. Because the tree is generated from your actual games, it quickly highlights blind spots and critical positions that books and databases may not emphasize for your rating range.<\/p>\n\n\n\n

    Preparing for Opponents With OpeningTree.com<\/h2>\n\n\n\n

    One of the strongest use cases of OpeningTree.com is opponent preparation. By building a tree from your opponent\u2019s online username, you can see which openings they repeat, what sidelines they prefer, and how they score in critical branches.<\/p>\n\n\n\n

    This lets you choose practical repertoire lines that steer the game into positions where your opponent historically performs worse, or where they rarely deviate from a predictable pattern. Many tournament players report using OpeningTree.com before each round to quickly review likely openings and refresh key ideas in their chosen lines.<\/p>\n\n\n\n
