Thom27: That's an interesting idea, but I'm still not convinced that Go can compete with Anti Backgammon in this respect. How many moves would a game of Go take when played this way? Forming the 'perfect grid' you speak of should take 180 or 181 moves, but you will most likely have placed some extra stones early in the game that don't fit into the grid. I'm guessing slightly more than 200 moves would be realistic?
