Different ratings at different time controls is, I think, almost universal.
As for risking losing some rating points ... that's just the risk there is. And playing fewer games will probably not help you improve. I know I got pretty rusty when I took a couple months off.
Hey guys I know this seems a little embarassing and ridiculous but I need some help as far as playing goes, because, as soon as I reach a better ranking, I get afraid to play new matches, concerned I might lose and get a lower rating. I know there are unrated games, but these feel uninteresting to me. Also, I seem to have very different ratings when it comes to time control, I am much better rated in games with higher time control. Is this normal?
All help is greatly appreciated! Thanks.
