Elo estimate (after EVERY game)???

Im confused. Did your example mean to say that someone saw someone else play like a 1900, but then realised that they were actually 1200? Or did the person know they were 1200, but then analyzed a game and saw that they played like a 1900?

Which streamer? Which stream?
My guess is that you misunderstood a joke or something, but it is hard to say for certain.

Like the person above said , you have to join the chess.com beta through settings. Though the estimatation is anything but accurate.

Just joined & enabled beta on my Android. Not really seeing a difference ...or what this beta club is. Might need to stop using app and log in on a browser
