The Chess Thread

My 10 yr old son has become addicted to chess over the past three months. Chess.com does offer lots of good options for him. He can play rapid, blitz, daily and also do puzzles. It seems to do a good job of grouping people by talent level. His coach just had him open a lichess account. I don't remember why they went that way, because they had been using Chess.com, too. I do feel safe letting him play games on Chess.com because he isn't having any interaction with his opponents at all, other than the game.
