I couldn't find any decent IQ tests. One had 30 questions but I had to send them a SMS costing £5 ($7.74), one had 150 questions and I gave up at the 65th (and I realised that I would have to send them my personal details anyway), another said "thank you" at the end at that was it and another only had 5 questions.
So, I accurately gave myself an answer:
IQ: 1416
Chess rating: very good
During the presidential elections of 2008, I was the only one protesting that didn't get tasered!
Funnily, lack of success in this field is one of the various contributing factors to my IQ of 5, which is a similar number to my true FIDE rating (did you know negative numbers had to be invented to assess my performance in a variety of fields?), and to my tolerance-for-this-topic rating.
