You can´t make a program in a deterministical environment comport
ramdomly.

As I state in my original e-mail

Since the only thing that make a computer program behave ramdomly is
a real random number input, and it´s likely that a pseudo-random 
input is enough for a Go-playing program, and even that everybody
uses the same pseudo-random generator there will be no problem, 
because you can chose the seed real-randomly before the tournament 
and this number is not public until the organizer verify the game,
when it's already done.
