My statement about ending play was not precise. Here is how the Ing style ending I suggested would work.

Bill: Re: "1x2 board" crossing over "Sending 2 returning 1" (2007-02-12 18:39) [#3074]

Dear Wilton,

It seems inconsistent with the result of a sole "1x2 board" or a sole "Sending 2 returning 1". Is it really the case?

Thank you. :-)

The inconsistency is not bothersome per se, since ko can unite otherwise independent regions (or boards). However, this version of my rules arose in discussion with other people, who objected to my suggestion of treating an odd cycle as a pass. So my original intent was to have this variation end with a White stone on the 1x2 board.

Maybe I'll have to go back to my original end of play rule, which stops play when the same player passes a second time in the same position. But people do not like that, either.

Maybe positional superko is better. People will accept that. ;-)

Best,

Bill
