I don’t play blitz. Chesscom they doIt would be wise to use averages to respect skill levels; otherwise, what's the point of the Elo rating? You can choose the skill difference between yourself and your future opponents. You think you're playing against someone of YOUR level, but no, they're twice your level. It's a losing battle from the start, and you don't know it (you can check, but if you leave, you'll be notified), so you waste almost an hour.

Can you tell me that someone with a 1200 Elo in blitz can be 591 in rapid 10/15? And I'm losing Elo rating. If you think that's normal, I hope that one day a player with twice your Elo rating will have the same rating as you. I'd love to hear your thoughts if that happens.

That is provisional rating given when a person is playing their first matches

The song remains the same. Online cheaters really make the whole game boring. And they kill my mood.

This topic isn't about cheating. It's a completely different song.
