Post subject:  Naturally finite Go variant: Goncrete 
I've long been trying to come up with an elegant, simple set of rules which succeeded in making Go into a naturally finite game, without the need for superko rules. That hypothetical game would no longer be Go, of course, but it should feel as close to Go as possible and preserve most of its virtues. Till now, my only (published) attempt at this particular task was Paper and Pencil Go, which was interesting but still far from ideal, as making life was too easy. Now I'm presenting Goncrete, which is a much more balanced game and, hopefully, closer to Go in its play. GONCRETE The rules are those of Go, with the following exceptions:

Could you show a sample game, maybe 9x9?

Better yet, let's play it.

Looks like the main difference is that you got rid of ko fights entirely and the ko is won by the player of captures first. Which in my book makes the game inferior to go, since ko fights are one of the most interesting aspects of go. And of course there are some changes to life and death, but I don't think those affect the complexity of the game too much. In particular it's harder to live with a big eye.

Not that it matters in this case, but I think you overfilled after 55 by your rules. It's the minimum number of fills to connect everything, correct? You can do that with 3 stones I think. Also, here's a "goncrete" puzzle for you:

You can do that with 3 stones I think. It isn't the minimum number of fills. You must replace the captured stones with stones of your own color. This is called 'flipping'. Then, you must remove one (and only one) stone from as many of the flipped groups as possible, and not "as many stones as possible from every group", as you probably understood. The rule you suggest makes for a different variant. In fact, it's one of the handful of ideas I have dismissed in my pursuit of a good, naturally finite Go variant. Not that it wouldn't be an interesting variant, but it would be harder to understand, and creating life would be somewhat easier. emeraldemon wrote: In Goncrete, it's dead. If Black captures at E2, he only gets one eye (E1 or F2). That's a good explanatory position!
