What's is Magnus Carlsen's IQ?

Ah yes, two of the ingredients that go on to making for a classic chess.com post.

I think Carlsen would be around 170.

The only thing I can say for certain is that a high IQ isn't enough to be a master. You probably need more of a perfect memory and the right kind of intuition. And then of course calculation skills. Imho, you don't need a very high IQ for chess at all (not of the kind that you need to understand very complex problems in general).

Oh yeah, and maybe, just maybe, it might help to practice.  And study.  A LOT.

At a certain point, a study buddy can be just as effective.

Don't you have something that has immediate results, lasts forever, costs nothing, and requires no work?

I do not believe there is such a thing that would exist from our point of view. As you would say: when cows fly, this would happen.

No, it isn't.

I don't know.  But for some reason or other around here, they always seem to.

IQ is meant to measure intelligence, not knowledge.

Yes, it's like those people who think "Ignorant" means "Stupid."

no, to be a true genius you have to realise a truth that nobody has even dreamt about

Kasparov's i.q. was tested by Russian psychiatrists while he was at his peak.  It was 135.  Well above average, but nothing spectacular.   Fischer's was measured much higher in high school, however, age is taken into consideration.  Often people are precocious (develop early relative to others their age) and when they are later tested as adults and age isn't factored into the equation their i.q.'s are much more normal.  I think it's safe to say both Kasparov and Fischer had fairly high i.q.'s but probably weren't geniuses in anything outside of chess.  That's my 2 cents. 

There is no evidence for a positive correlation between chess ability and IQ. 

 I agree and the most evident example would be the genius in chess Bobby Fisher, who in real life was rather erratic.

Bobby Fischer was undoubtably a very bright person. His erratic behavior had to do with mental health not mental capacity. 

Einstein said, "Imagination is more powerful than knowledge." His IQ (i think) was 144. Child prodigies are called geniuses, however, many lack in other skills and areas of life the commoner would consider basics. Albert, probably could balance his check book, if he wanted too. Read my blog. Anyway, i don't think you have to be a genius to achieve chess greatness. I have the utmost respect for those who dedicate their lives to such a grand achievement.

Mensa's requirement for membership is a score at or above the 98th percentile on certain standardised IQ or other approved intelligence tests, such as the Stanford-Binet Intelligence Scales. The minimum accepted score on the Stanford-Binet is 132, while for the Cattell it is 148.^[9] Most IQ tests are designed to yield a mean score of 100 with a standard deviation of 15; the 98th-percentile score under these conditions is 130.82

   This list is bogus.  Many of the people on the list died long before standardized i.q. tests were INVENTED!  Those must be estimates or educated guesses.  The i.q. test was invented around 1905.  Da Vinci DIED in 1519 and Newton in 1727!

   People (and this list) keep saying that G.K.'s i.q. measured 190 but according to this source, "in 1987-88, the German magazine Der Spiegel went to considerable effort and expense to find out Kasparov's IQ. Under the supervision of an international team of psychologists, Kasparov was given a large battery of tests designed to measure his memory, spatial ability, and abstract reasoning. They measured his IQ as 135 and his memory as one of the very best." So I was wrong when I said Russians, it was a German magazine hiring an 'international team of psychologists'.  

   Regarding, childhood i.q. vs adult i.q., wikipedia says, " To convert a child's IQ score into an adult score the following calculation should be made: child IQ score/100*age/16*100 = adult IQ score. The number 16 is used to indicate the age at which supposedly the IQ reaches its peak.^[40]

For decades, practitioners' handbooks and textbooks on IQ testing have reported IQ declines with age after the beginning of adulthood."

   Those are the sources I come up with in a 10 minute google search.  To the couple of people who want me to name names and supply sources and conduct scientific studies, that's all the time I have for this.  We are chess players pontificating elite player's i.q.'s not scientists conducting research nor journalists. 

   It should be obvious that if a child is extraordinarily precocious, a 'child prodigy' they might score higher on a test relative to their age piers they might not score so much higher later when the others catch up. I'm sure Fischer was high i.q. but not 180 or 187.  He was gullible with religion, with conspiracy theories, and in 60 years never figured out how not to piss people off and get along with others.  He was a child prodigy, a chess savant but not a universal genius. 

   That's my 2 cents, as in, my opinion. I could be wrong.

Perhaps because only chess is logically sophisticated enough for him to be amused.
