How to import a PGN file in Anaysis mode in Chess.com

You can't import a game and get the chess.com computer to analyze it.
There's no reason to do that. Just get a free chess engine like Stockfish and use it. The result will be much deeper and the engine much stronger than anything you could get here.
The chess.com computer analysis is only for games played on Chess.com.
/ You can post a game here on the forums (using the Game Editor-- the little chessboard icon) and (sometimes) get human help with the analysis.

You can import games Into the analysis board in Live and have it computer analysed if you're on the new Chess.com ("V3" - if you're on the Old version, look at the bortom of the page for a link that says "Try the new Chess.com").

Well I suppose that's good news but you have to enter the moves by hand and again, you will get a much deeper analysis much more easily using one of the free engines available on the web like Stockfish.

If you already have the game in a PGN you can just import that into the analysis board. No need to reenter the moves by hand.

Open analysis board, click load pgn, then paste your pgn then click analysis. I don't understand the confusion.

Help! I keep getting the message "unable to parse that pgn" when trying to load in the Analysis section. When I open the .pgn file in a text editor it looks fine.

You can load any PGN you want into the analysis page. You just copy and paste it in, with or without headers.
If your interest is ever in taking a screenshot or in recording screen capture, leaving out the headers on the PGN will give you the biggest board, especially in fullscreen. I believe it's 1048x1048.
To get the analysis to work, make sure "Self Analysis" is unselected.
EDIT: Sorry. I just necroposted.
Hi all,
I am new to the Analysis mode so I was wondering are there any tutorials on how to effectively use this feature. In particular, how to import an existing PGN file, and then annotate it.
Any help appreciated.
