What is Magnus’ IQ
I mean for example Albert Einstein had a iq between 150 to 170.... And he wasn't a great chess player...

Hikarus is not 102, that was just from an online test which is not accurate. Magnus’s is estimated to be 180 after you plug his rating into the equation (IQ x 10) + 1000. This is for the maximum rating a player can achieve.

There is on both ends of the scale high IQ + hard work = good chess player
low IQ + hard work = decent chess player
hikaru only 102?!
