Here's one for you tournament directors and rules experts out there.
I'm probably missing something obvious (and will realize it just after
I send out this post), but here goes:

ABCDEFGHJK
In the diagram above, the white stones are obviously dead. The
question is: does white profit by playing G1, forcing black to connect
at E1? (There is no current ko.)
It seems that, under AGA rules, the answer depends on whether we use
area (Chinese) or territory (Japanese) counting. I thought that wasn't
supposed to happen.
Under area counting, all of this area belongs to black and prisoners
don't count, so clearly white's struggling is irrelevant.
Under territory counting, the G1-E1 exchange gains one prisoner for
each player and costs black a point of territory. (Both players play
one move, so the pass stones aren't relevant.) Isn't this a gain of
one point for white? Is it the same under Japanese rules?
