IQs of world chess champs

Kasparov scored 135. No need to try to estimate his iq. I think that probably shows that chess skill is a special type of intelligence that iq tests don't really measure. Hikaru Nakamura scored 102 on an iq test, but that was online, so I wouldn't put too much stock in that. My opinion is that the estimated iq of chess world champions is greatly exaggerated. Richard Feynman only scored 125 on an iq test. Maybe that says something about how poorly iq tests measure intelligence, but if you're putting a number on it, that's what he scored.

Chess skill is just a matter of deliberate practice, obsession, and learning from mistakes.
IQ is mostly unrelated - as long as the player is able to understand the basic rules of the game.

Repeated studies seem to reveal a weak, but probably real, correlation between IQ and Chess skill. But almost all the numbers in post #1 are complete made-up nonsense

Was Nigel Short a former World Champion or a challenger, if anything?

Not almost. All the numbers are nonsense.

Read this book two years ago. Does a good job of explaining the nature and purpose of IQ testing, as well as how these numbers are misunderstood and abused.
