Delete game from archive
You presumably had an opponent for those games.
If you were able to delete games, it would affect your opponent too and all the opponents you have ever had.
They could anonymize me for the opponent and they could keep the game but Chess.com simply doesn't want too. Just seems idiotic that I can't control my own game history. Fully realize this is a futile effort at this point but it really keeps me from engaging with the app.
