I admit to having a fascination with this concept of intelligence etc
As I alluded to in another post on another thread, my elder brother is/was a chess "genius"
http://en.m.wikipedia.org/wiki/Julian_Hodgson
Britsh chess champion 4 or 5 times, in his prime he had an ELO rating somewhere north of 2600, that put him I the top 20 chess players in the world, he has played all the worlds greats - Kasparov, Karpov et al
I was a very very poor performer at school/academically - it was additionally "tough" to be constantly compared to a "genius"
But he is absolute cannon fodder to any daft CT out there, and as I said in that earlier post - I would not trust him to open a crisp packet
