Has anyone else found that the competition on ICC and FICS is a bit steeper than over here on Chess.com or is it something I'll just see level out over time?
I think you are right. I also play on a Polish online chess website, and what I've noticed that a lot of people here on chess.com are really casual gamers who don't know their openings and play as they please. On the other websites I feel there are more professionals or semi-professionals.
Ive competed in several USCF events, and ive been performing at about a 1650 level. On chess.com, my live standard rating is about 1500 and correspondence is 1600. I think that chess.com ratings are lower than their equivalent USCF ratings.
