No its not any good...
1500 ratings across all time format, is it decent?
I had reached 1790 nationally rated without studying anything. When I discovered solving chess tactics and studying I did not join OTB tournaments again. I got addicted to chess training. I do not care about tournaments anymore since then. I did not know I was naturally good in classical games. I struggled online blitz and rapid even if I trained chess a lot. Now I know how I remembered people asked me what chess books I am reading, I said I do not read chess books. They did not believe me.
No studying or anything, just playing purely on instincts, intuition, logic and minor calculations like 2-3 steps.
