Cool, thanks. I got working on this and it's really amazing how who wins really depends on the other entries.
I am going to enter, but I want to wait to submit my entry based on how many other people enter. I've got three different strategies that win at different times based on which other strategies I enter in my test tournament.
The more people that enter the better, because it is funner and more interesting. And as far as I can tell a complicated solution might not have a better chance than a simple one depending on the other entries.
