I've never had my IQ professionally measured but I'm fairly sure it's high (I'm an engineer who never really needed to study much in school, I was a point short of perfect on the ACT, always been a good test-taker).
Here I am sitting at a 960 rating. I've played chess on and off my whole life but never seriously studied it. So does that mean I have a low IQ? Or maybe as kimberlyja suggested I'd have a high rating if I took the time to study chess seriously?
according to that formula, my elo is about 2400. you know, i dont think im a grand master.
the ideea is that you might have 2400 elo if you'd study chess like a pro
