IQ is an indicator. it does not gauge your intelligence, it can only indicate a maybe u r maybe u r not. I quite agree with SteveM. It is well documented a person could be skilled in one area and a dummy in another. Also we should not confuse skill from intelligence.
Chess and IQ.

Why is it that everyone on the internet seems to have genius level I.Q scores?
Microsoft!

I played a 14 year old math genius with an IQ of 165 chess. He played very well and beat me. I'm rated 1712 USCF. Therefore, yes, IQ plays a critical role in chess ability.
Yes I have a friend who doesnt play chess often,but he has a very high IQ.My other friend does indeed practice, but he loses to my non-playing friend in tactical areas.

Thanx.

yes it depends,i have seen manyyes it depends,i have seen many person with high iq learn person with high iq learn to play chess very easily.

I think of IQ as a tool that a player brings to the board with them. IQ may be important in solving tactical problems, but it is experience that gets that position set up in the first place. Fischer, Kasparov, and Tal may or may not have been geniuses, but the fact remains that they were practicing their game far more strictly than the average player. They didn't just sit at the board and play well from the start, all three had mentors or coaches that trained them along the way. Even Fischer grew up reading about the Russian grandmasters and their games. IQ may give a person an advantage, but he/she must first use and expand their "chess knowledge" by doing the studying.

i have to agree, there are loads of such tests, Beethoven was deaf, a deaf composer!!!!
Beethoven was not deaf untill the very last years of his life and even at that time he was never completely deaf but had periods of hearing well. His syptoms started when he was a matured and educated composer and deteriorated only gradually over many years. I know it´s tempting to call him deaf and then marvel at his genius (which is unquestioned, of course) but it´s inaccurate.
