Chess.com Analysis at Lichess
Extension Actions
- Extension status: Featured
Opens PGN of a game from chess.com or chessgames.com in lichess.org analysis
This extension has the following features:
* Allows you to view lichess analysis for any finished chess.com game.
* Works from the Game Archive as well as from finished live games
* Also supports chessgames.com, chess-db.com and chesstempo.com
I am not affiliated in any way with lichess or chess.com (but I'm a fan of both).
I'm not playing chess as much right now, so if it's broken, please let me know at [email protected].
Many thanks to all contributors!

- As others have said, it currently doesn't work, it used to open a new tab with lichess, but now it doesn't open a new tab. Must be some new thing chess.com or lichess implemented that messes with the current code for the extension

- Great when it's working! Thanks to the developer for making this. Sometimes, it doesn't work after a game. Occasionally if you refresh or click profile and go to the game that way, it will after sometime. I believe it works from both post-game and analysis board.

- Great extension. You have to use it when you are on the analysis page of the game on chess.com or else it won't work, but other than that it does what it's supposed to.
