Lichess.org rating vs rating in real life How does a chess rating at Lichess.org compare against a rating in real life, in classic chess (more than 8 min)?
The largest problem with sites like LiChess and Chess.com is that the standard pools are not very reflective of Over The Board rating. Most people play chess online for the Blitz and Lightning games. Chess.com recently came out with some statistics that showed that their Blitz rating pool is roughly the same as USCF currently. I do not know how well that would translate for the Standard pools.

When I was 1900 playing G/30 games on Chess.com and ICC (Internet Chess Club), I was rating roughly 2100/2200 on both sites. This was years ago though, so again, not entirely sure how accurate they are.
