Is it because I am not focusing while I am playing online?
USCF VS CHESS.COM
That is odd. Well, a simple explanation is that some people are better online, and some over the board. Although I believe that Chess.com rapid is about 300 points more than USCF, one, that is my opinion, and two, there are disparities in one's performance in OTB vs online. You may just have to get used to online chess if you have played OTB the majority of your chess career.
Guys! I am around 1630 in uscf ratings but my ratings here are so low! Why?
