That last picture is what I am against. You are using a score estimator as a scoring tool. They are different. Their conflation online leads to so much beginner confusion. Teaching beginners in real life this problem simply doesn’t arise. You say “maybe it is against some old rules”. I say “it is against all current rules, and inventing new rules to make this valid is introducing bigger problems that the one you are trying to solve”. If you allow that, you also allow saying j3 is black, j4 is white, j5 is black, and d4 is white or other arbitrary patterns. The way to sensibly deal with this situation is:
- resume the game and close the borders.
- if players don’t want to resume, or server prevents it because of e.g a procedure in which AI scores and marks the game and give hints about good moves which means you don’t want to allow resumption, then no one gets any territory. This game ends up with a score result which is different to had the players been sensible and continued the game as competent players. That is acceptable, and better than breaking the rules of Go to avoid it. The beginners then learn a valuable lesson from this one game, and don’t make the same mistake in future. They also don’t complain to a mod who then changes the game result.
