Sorry if I start sounding repetitive, but please add comments.
Only problem I see with your code (apart from redistribution mentioned
stuff) is that it doesn't see the randomness of the fuseki move
generator.

Well as I said, I would think a script to interpret these results
throughout a game is enough IMHO.
