What is considered intermediate/not beginner?
I dont know. I know that more people are better at chess today rhan they were 4 years ago. I know at 650ish, it says I'm better than 65% of people.
Don't get me wrong, I suck. I have some good knowledge through hard work, but I wouldn't say I'm a beginner. Advanced beginner at least? In my very unexperienced opinion, I think anything above 500 deserves at least a sub-class of beginner. 800 for sure, these days on chess.com, not a beginner.
Im 1200 on lichess
GothamChess says 1000+ is intermediate, 1500 early advanced and so on. If an IM says that I believe him more than any random user on here who says 1000 is still beginner (which it definitely isn't).
