Life In 19x19

This referee behaviour might have changed after 1989... but I doubt it, my understanding always was that the rules were basically meant to "explain" and "give logic" to the existing practices, and most players and referees (I think referees are usually also other players?) did not significantly ...

Thus a player can even refuse it and demand dame to be filled in actual game (or resumption), with actual moves and with actual consequences. Nope. They are free to resume the game and play Dame themselves. But again, the rules do not allow the player to make any such demand and there is no ...

I might be misunderstanding both of you, but I think it boils down to this (and please correct me if I am misrepresenting each position):

- CDavis7M says that the rules say: "filling dame (implicitly meaning not "seki-dame" but "true-dame", all of those that you would fill in Chinese rules, where ...

When you say "There is no possibility of stones being captured by the placement of stones after the game is stopped", do you mean

1) That stones cannot be captured "accidentally" and more importantly "irreversibly", without the players' consent, because those moves are not irreversible main-game ...

Yeah, "Enlarging strings matter" is exactly what happens in the pseudoseki example linked before that I described as an example of "one sided dame".

Interesting indeed.

"Filling dame" in this context clearly means filling those dames that are not suicidal, those of the normal groups that can be filled without dying because of the liberty reduction.

It is obviously a highly "informal" and "based on intuition" thing, not formal. It is mandatory to fill "those dame ...

Sorry, I just found that in the rules I linked, there is extra text commentary between the "main text" and the "examples and precedents". So the full text is available it seems, and there it says about dame and teire. I must have read that once many years ago, and then completely forgot and only ...

This is huge for interpretation of the rules, because then if the final position that players leave on the board is not really that "final", as it is not if it can be argued that Teire, dames and all other "necessary protection" moves must be filled before life and death determination starts (even ...

Wow, there are a few additional lines with clarifications in the official Japanese page! I have never seen a full translation for those. I mean, the only translated English text of the Japanese rules that I have seen is http://www.cs.cmu.edu/~wjh/go/rules/Japanese.html

This seems to be a direct ...

Is it MANDATORY to fill one sided dame? I did not know that.

Is that based on informal, intuitive understanding of what dame / one-sided-dame is?

Unless it was ruled mandatory, a player could avoid filling his one-sided dame, for it to be there on the board, and allowing it to count as "enabling ...

Ah, the "both players lose" clause is another beast altogether. I guess that might change things depending on exactly how you interpret it... I am simply ignoring that rule in my analysis.

My understanding is that it is safe to pass under the Japanese resumption rule: "for whoever asks to resume, then the other player starts". Your opponent pass, you pass - you don't ask for resumption. So that way the game either goes to scoring directly, or it resumes and it is your turn - thus ...

You mean that it is not safe to pass after the opponent pass in the molasses ko because if you do, then the game goes to scoring and life-and-death considerations rules your group death and the opponent's group alive? A resumption would not occur, as Japanese rules say that the opponent of the ...

But that interpretation of passing for the ko "only once" does not handle both molasses ko (https://senseis.xmp.net/?MolassesKo) and the following "long double ko seki" at the same time (as far as I understand, both cases should be seki under Japanese rules):

Are we 100% sure that Japanese pros would rule both the left and right parts in these examples as truly independent for ko analysis? Do we have a source, or is it speculation? My feeling is that indeed they would, but I would not be completely sure without an authoritative source. The position feels ...
