As for the OP, I sometimes wonder what a GO variant in which no zero liberty group was allowed _ever_ would be like.
I mean removing the rule that a group of zero liberties can be created if it captures another group.
If you would not be allowed to capture by creating a zero liberty group then:
- there would be no KO
- one eye was enough to live
- false eyes would become true eyes
- a lot more seki would appear
What I wonder: would it be a game way more simple or almost equally complex?
