That used to be one of the features of "Game Explorer" here, an ability to look at your own games, but it has been broken for 3 years now.
They have attempted various fixes but as I understand it, they would need to upload tens of millions of games to the database at this point and they just don't have the capacity to do it.

It would be really useful if Chess.com had a feature to sort a player's games by opening. Then we could see which openings we performed worse with, which ones we needed to brush up more on.
Currently I have 8000 blitz games and manually sorting them would be a monumental task because I'd have to download each and every one of them, check the moves on my own, create my own database, blech. But it seems like the site could do this much more simply. Or even if it gave me an option to manually tag games by opening so when I scroll through, I can see it easily. I believe some other sites do this.
