Don't understand why people seem to think being good at chess is directly correlated with being smart. Chess is just a game that you can get better at through practice like any other game, you can be average in all other respects but still be a great chess player. Sure lots of smart people like chess, but lots of different kinds of people like lots of things. Guy I went to school with was dumb as a rock but was ranked among the top Junior league chess players in the country or something like that cause he was awesome at the game. Even Bobby Fischer(who reportedly had an "astronomical" IQ), and is considered to be one of the best if not the best player ever, developed his phenomenal skill through countless hours of practice and devotion because he was utterly obsessed with the game - upon beating almost the entire Soviet team singlehandedly at the world tournament, one of the players remarked that Bobby put more time into chess than the entire team combined. It isn't really something where you have to be intelligent to do it like advanced math or physics and whatnot.
