A tree of traps and openings for chess, under development. Comment and save your own moves. Import and export games as PGN's.


Using for building opening repertoires:

  1. Switch from "Common openings" to "Overlay statistics" in the databases-panel. This will overlay the win-loss rates and use prevelance from the selected skillset on your moves.
  2. Your tree is generated as you move pieces on the chessboard.
  3. Select save from the menu bar to save your tree. You can save public tree, or register here to manage your own private trees.

Thanks to jhlywa/chess.js and for the chessboard!
