The grandmaster Johnathan Levity has put forward his famous formula .
ELL = 10 x IQ + 1000
This assumes dedicated study and practice . In my case I could have reached 2050 but many of us are unable or unwilling to spent so much time.
Computers have no intelligence but play by number crunching.
This formula is quite bad, as Kasparov was tested and got an IQ of 135. By the formula 10*(135)+1000=2350, or a strong FM. If a formula can't decipher a difference between FM's and a world champion, it's not of much value.
Kasparov was 10th in the highest IQ list.. His IQ was 194, and not 135.
IQ has little significance to chess, just put in the time and you will get results
Of course IQ has big significance to chess.
With every game you encounter new positions and it's up to your intelligence to analyze and figure out the correct moves.
You can't dismiss the importance of IQ and say it's all just hard work. that's pretty much an insult to all high ranked players.
I bet no average 100 IQ can ever become GM, IM, FM or even CM, no matter how much time he dedicates to it.
Not all GMs are IQ 140 and above.. Of course they have an higher IQ than normal players but an average 100 IQ can of course become a GM or atleast IM.
IQ is a measure of native thinking speed and ability it is an attempt to estimate raw intelligence without learning . Take me Im slightly above average but at the age of 76 I have quite a lot of knowledge.
Chess played with clocks.
That's your ignorance. i know a couple 100 IQ CMs and FMs and they are steadily making progress towards the IM title.
The formula is interesting but it s not IQ that is important, it s memory and the ability to visualize the resulting combinations (visual memory). Players with great memory willing to spend time on their game can get very far. Kasparov s IQ was indeed over 130, but his score in memory IQ was one of the best they have ever measured, the current champion is known as a mind that does not forget, practically every strong player can play bliindfold chess on decent level while an average Joe is unable to find even 2 shot combos most of the time and hangs his pieces because his memory is limited.
Such visualisation and extended memory may well be part of the I IQ test. We have little knowledge of just how humans play chess , but one thing is certain they don't number crunch but seem to possess a sort of intuition difficult to explain.
There are mathematical prodgedies who can memorize huge lists of numbers , yet they cannot explain just where this 'gift ' comes from.
There are a couple of "important" things in chess and once someone teaches them to you the IQ doesn't matter that much. The time you put into it becomes more important. But if someone had to discover everything by himself then definitely having a high IQ would be handy.
