Sorry, but I keep looking at that and can't see how the final position cold have been reached (in ko) EXCEPT by black having passed after white had made a self atari move.
Care to present the last half dozen moves or so instead of just the final position. Say from a couple moves before the two black stones were captured.
Oops I do not see what is really your problem. Anyway here is an example of game (without any pass)
Misunderstanding. I was referring to the FIRST example, not any later ones (where there would be a variety of methods to reach the final position.
The first has exactly two "cases" for when there are still the initial two black stones present.
a) white has filled such that the only two dame left touch those stones (black has been passing as white has been placing stones. white fills one of them placing the two black stones into atari. BUT that is self atari. I am willing to accept black being infantile, but are you requiring black to also pass in THIS situation instead of capturing all the while stones?
b) White has filled such that there is one dame somewhere else (it does NOT matter where) and one adjacent to the two black stones. Then there are two laces white can play:
1) Fill the external dame --- see "a" You are requiring black to pass while white is in self atari
2) fill the internal dame capturing the two black stones. Now if black plays back in it is NOT atari. White is alive, need not capture but can at the cost of a point -- black has no legal play in either case.
In other words, I will allow you stupid/infantile moves to reach the positions but not obviously willful suicide like failing to notice that the opponent is in self atari. Of course, that COULD be a ko threat << give up a seki to win a larger ko >>
