What IQ do you have to have to be a grandmaster?

looks like i have

I meant in order to achieve the title of grandmaster. You got me there.

Technically there is no IQ restriction so theoretically nothing is stopping a retard from obtaining the title.  Practically however you have to be at least gifted probably since obviously a retard or even an average wouldn't have the practical mental tools to obtain such a skill level.

This talk about IQ is always a little strange to me because IQ is not constant at all. I think there is quite a bit of elitism in the thinking that our brains are just a result of genes and not also the environment. It's much cooler to say that I was born with X or as X than to say that I worked my ass of to be X.

For Kasparov, who went from iq135 miraculously to more than 180! Imagine Fischer's against Kasparov's 135. This is not possible. Of course, Kasparov IQ must be higher or not? It is maybe just that IQ , above a given "critical" IQ range, isn't significant to become a grandmaster? But, also, you should have no doubt that elite grandmasters have no "low" IQ. This condition being necessary but not sufficient, certainly. 

You have also to take into account the standard deviation used (15, 16, 23). For instance, Fischer's astronomical "American" 180 (standard deviation 23, probably) amounts on other tests (Raven APM, Wechsler's) to about 155 (like Tal's 157, I once read), mostly used in Europe. It is necessary to be very careful with IQ, not only because it is based on specific abilities and not all intelligence's facets, but also because, as has already been mentioned in the thread, different tests have different spreadings and IQ's are not exactly the same. It is better to speak in terms of statistics or sigmas. 

It's not about IQ, all you need for chess is a good memory and a interest in chess, the will to really improve and not be lazy.

Now tell me who is smarter the unhappy person with a high IQ or the happy person with a low IQ??!

To think that humans are smart enough to judge someones intelligence is laughable.

What do you need for chess? I tell you: a good memory, nothing more.
If your heart is not in it you wont improve much, no matter how smart you think you are.

I think what leads a person to GM is probably practice, study and a huge love for the game. A photographic memory and fast working mind would be an advantage though.

With your IQ you can expect to become a GM by the end of this month.

My IQ is predicted to be 160+ and I'm not a GM, so GMness does not depend upon IQ

That's a super high IQ, brumtown. Put that to use.

My IQ is predicted to be 160+ and I'm not a GM, so GMness does not depend upon IQ 

160+? On which scale, with which standard deviation, on which test, at which age? On Internet?

Anyway, you sentence is a good example of brilliant sophism! 160+? Hum...

My IQ ( from a Mensa test) is 164 and I'm a pretty crap chess player

Live at Mensa or on Internet, just to understand? And with which standard deviation?

Anyway, you are right. As I said a (very) high IQ like yours does not guarantee success in chess. I know several people from high IQ societies who have very high test results. This doesn't impede them from being rather weak players. Motivation is essential. Study-time spent also. Practice (with or without strong opponents). And so on.

Hi!

I want to recommend my app for you guys, it is called: Brain Training Chess, It is a chess working memory game designed to increase IQ etc. It is available in the appstore now and costs only 2,99 dollars. I have many years of experience in brain training and I really think this app is one of the best brain training applications out there. If you have any feedback or questions about the app just ask away.

Best regards,
