What should a 13 year olds rating be?
So if I understand correctly, you have been playing casually the whole time?
Does anything about playing chess excite you? When you figure out a combination, do you feel good?
Have you ever tried to serious study a book or course teaching you the secrets of chess? Are you a good student?
I enjoy playing chess because I like to win and I like to see my rating improve, and I like to be better than my friends who also play chess.
When I figure out a combination, or even just the best move in a hard position, I feel amazing.
I have never really tried to study a serious book about chess, just some for learning basic ideas and tactics.
If a topic interests me, I am a great student. I haven’t really look for any coach really though, free or not.
