The strongest grandmasters of the day with their ratings hovering around 2800 are expected to have IQs around 180.
Don't kid yourself with these speculations. If I was in Top 10 or a Super GM I'd be willing to take a test and demonstrate my inhuman IQ (Feynam's documented IQ is just 123). They're good at chess, not at raven matrices.
Dear NW, did you bother to read any literature about the IQ's of top GM's?
I'm assuming you're one of those guys who are pretty weak at chess but feel that because you're not too bad at something else requiring thought [math] that there must therefore be little correlation between chess & IQ?
Perhaps we should use your reasoning about great thinkers in any discipline...why should excellence in chess be any different? Are you familiar with the concepts involved in endgame technique or strategy in closed positions...not to mention the ability to accurately calculate complex variations with a high degree of accuracy?
I've completed my degree in Engineering many years ago...but I hit a brick wall with my chess years ago...it was just much more difficult than getting a degree with no security. Maybe I could get to 2200 if I had really studied intensively, but instead I'm only 2000.
I think you under-rate master level players, and particularly the world greats!!
I'm a member of Mensa with a 150 IQ and your statements are nonsensical, irrational, and do not reflect high intelligence ... in particular your completely baseless ad hominem assumption about someone's chess skill derived from their comments about a correlation simply because it differs from your own beliefs. You allude to "literature" about this correlation but provide no evidence that such literature exists. The fact is that the literature that actually does exist--the studies by Adriaan de Groot--shows that chess skill is correlated with very chess-specific cognitive functions, not with general intelligence.
my sped friend is rly good at chess, he's 1600, while I'm still OTB 1000 with an IQ of 150
