IQ: I've scored 96 and, 123 and 145.
My chess score: Mostly between 1200 and 1400.
However, when I was eleven (St. Josephy's school, 1981...I believe) I became school chess champion in the Strathclyde area in Scotland (and didn't play a game of chess for 20 years there-after).
If I have a good day I play a very good game of chess. Most days I don't have such good days, so this correspondance chess doesn't do me justice. Or maybe it's the drugs, booze and porn which keeps me from winning? I dunno...
