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.
That checks out. I think I beat most of my friends simply because I remember a chess aficionado mentioning the center as being important to hold.
