ELO ranking beginner Level

Sort:

Hello, I need your help to understand the following…

I created my chess.com account years ago and dumped my elo rating to somewhere around 600-700 in rapid and around 500 in blitz.

In the last few month I started to play regularly again and created a new account on lichess to play some of my friends. My elo over there is 1200 in rapid (after around 200 games) and 1000 in blitz (around 100 games).

Can you explain to me why I have almost no improvement of my elo on chess.com? Shouldn’t I “crush” most of the elo500 opponents if my elo would really be around 1000-1200?

Thanks for helping me understand the mechanics… ;)

Hello
The Rating System in chess.com is not the same as in lichess

Lichess has a much smaller playerbase so there is less competition and hence your rating is higher there. Much like your blitz rating is lower than your rapid as more people play blitz. Your chess.com rating is more accurate as you are compared to a larger playerbase.

You're correct. If your true rating were 300 to 600 points higher than your opponents then you would win almost every match.
