Sure, playing chess needs intelligence, dedication, and good chess players are smarter than an average person. But it’s waaaay exaggerated in movies. I’m a math researcher, and in any movie, my department will be full of chess geniuses. But in reality, only about 10% of them even play chess.
“show me your non-provisional rating and then we can talk”. Yeah I agree. But then this is the internet and everyone is an expert at being an expert lol
