So, you can find it on the net:
Garry Kasparov: 190
Bobby Fischer: 167
Judith Polgar: 170
Robert Byrne: 170
But Carlsen, should we guess, would be around 180-190
Notice how 9 years later all these IQ numbers are still all rumors/myths.
If anyone ever claims over 160 IQ without proof online, it's bogus. I know, you'll say there's a non-zero chance it could actually be true. Nope. It's a law of physics, like the speed of light. Unsubstantiated online claims of 160+ IQ are false 100% of the time . As you approach 160, the chances of being false increase exponentially until...bogus.
This applies to news stories and magazine articles as well. Anecdotal allusions to 160+ IQs are false 100% of the time.
Good
I wish there were some kind of penalty box for people that bump years-old threads without adding anything useful...so let me add something:
