[computer-go] Disputes under Japanese rules
I've asked this question of a couple of people and got different answers, so I thought I'd check here. Suppose, under Japanese rules, I throw a (hopeless) stone into your territory. I keep passing until you've actually removed it (playing four stones inside your own territory, thus losing a net three points). If you try to pass as well, I stubbornly insist that the stone is alive, thus restarting the game. What prevents this sort of abuse? Is this one of those cases where the tournament director has to adjudicate? (This is not a problem under Chinese or AGA rules.)

What prevents this sort of abuse? iirc, if you can demonstrate that the stone is dead, then you do not have to actually capture it. this probably works ok except in strange cases like http://gobase.org/online/intergo/?query=%22mannen%20ko%22 and http://gobase.org/online/intergo/?query=%22itte%20yose%20ko%22 where one can argue about it or get confused. thanks --- vice-chair http://ocjug.org/ ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
RE: [computer-go] Disputes under Japanese rules
If I'm playing Japanese rules I would not respond to your pass by removing the stone. I would pass and end the game. If we disagree on the group status, you get to play first and make it live. If you fail to make it live, then we now agree on the status of the group, and we restore the position to what it was when we both passed, and score it. In practice this rarely comes up, and when it does, is often adjudicated by a strong player. A more difficult situation is when both players pass, they disagree on the status of a group, and the group is in fact unsettled, so whoever plays fist wins.

[computer-go] Re: Disputes under Japanese rules
Japanese rules have two procedures to stop the game and to verify the score (these names are my personal, not official). In the case you mentioned, your opponent has no needs to remove the stones, if he/she thought the stones are dead (exactly speaking, he/she _can_ make the stones dead). So, he/she simply play pass and the game ends. After the end of game, the players can continue play to check the stones are really dead, if necessary. This procedure does not affect the score if the stone are really dead. The idea of Japanese rules is that the players have no need to remove any stones those are dead at the end of game.

Re: [computer-go] Disputes under Japanese rules
It's a shame that such a great game has such a silly/ambiguous end-game procedure. Can you think of any other perfect-information strategy game that comes anywhere near this level of ambiguity? Go is known for it's simplicity of rules and complexity of strategy. The Japanese scoring system, while popular, does not exemplify the simplicity of rules attribute. Chinese: good. Japanese: bad.

Japanese: bad. I don't think this is the case at all. The Japanese rules are just a human optimization, to avoid having to make the last 100 meaningless moves, and still arrive at the correct score with a minimum of extraneous manipulation. The tortured details, while not elegant, rarely matter. ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
