Is there a clique of chessplayers with high IQ?
They probably totally suck at chess.
I have higher degrees and according to the old adage, BS, B_ll Sh_t, MS, M_re Sh_t, and PhD, Piled Higher and Deeper. Based on my High School IQ my guidance counselor advisor me to be a baker; certainly not a chess player .
I was supposed to be a barber, based on similar guidance. I liked to help guys with their combovers.
