I'm much lower rated player than you ... but it's also been my experience that Lichess is about 200 points higher. I've heard that from several places, I believe it's just how lichess structures their ELO metrics.
Lichess Vs Chess.com at High Ratings
Sort:
So I know at high ratings lichess and chess.com is meant to be equal. But I've tried hard to get my lichess bullet rating here and can only get 2300 even though I'm 2500 on lichess.
Can any higher rated players tell me if this is normal? Am I just bad at chess.com? I don't think I can get 2500 here.
I improved my rating here after switching from mobile to laptop but it's still low.
