On the other hand

In this earlier post I mentioned the Ian Rout theory of 'handedness'. Buried in this report on a couple of studies on what makes someone good at chess is another measure of handedness. The statistic quoted is that 18% of chess players are left handed, as opposed to about 10% found in the general population. Now as a right hander I'm not really sure of the significance of this, but I am sure that left handed chess players will be able to explain it as some sort of evidence for the innate superiority of left handers.
