Ok my original statement was harsh. I apologize. I had no idea you had been spending 12 hrs a day studying/playing. However you still might need to readjust how you're studying because 12 hrs is a lot of time. Again this might be situation of quality over quantity.
It's all good. What I realized about chess the other day is that if you're always paired up with someone of the same strength, and you're always pushing your thinking to the limit, you'll always have the potential for a great game.
The quantity of games means nothing if you're not learning anything from them. Perhaps you should spend more time studying and analyzing than just mindless playing.
It's always strange when someone claims to know more about me than I do, while displaying an inevitable lack of context. I do a lot of study/instructional stuff because it's almost impossible for me to learn. Literally. All I can do is encourage a manic state of wanting to perfectly describe the game. In the latest of those states I created chessnerd[.]net and its correspondingly (empty) YouTube channel. After devoting three days of non-stop intense concentration to the video project, I made slight progress in learning about the Italian Opening. That's the reason I'm usually in the 600s. The reason I have over a thousand games is because I devote about twelve hours a day, at least, to chess. Every day. Mostly study. But it's a binary, so I either do it or I don't do it, and I'd rather play chess. Playing the game means looking for ways to improve, however quickly.
