I see your point, and Congo is indeed a childrens' game in more than one sense. Playing it against me would prove nothing however. I'm an inventor and wired differently from a player. At Chess variants I'd have to work hard to reach 'bad', never mind mediocre. So a game between us would not amount to much of a proof of decisiveness :) . I'm glad you upgraded it though, and I thank you for delving into it.
