@Francisweed - yes, I think the assumptions of this post are mostly bunk on the face of them, not to mention whether trying for a rating above your true skill with stupid tricks is really something people should be perusing.
The closest I have come is playing daily chess. There are a few times when I have noted that my opponent was playing late at night in his time zone, and sometimes even playing poorly, and I'll make a point of responding right away in order to play as many moves as possible while I'm at an alertness advantage. I don't think it comes up enough to really affect ratings.
Thanks for your response Powerish - you have highlighted precisely the way in which you can implement the "Timezone Method" to your advantage. So its obviously not bunk at all - its just that no-one has bothered to dot the dots and do a serious study on this phenomenon, oh, and face the endless criticism for putting forward such an "outlandish" theory.


he is an "aussie man" after all
