How should the play go?

(More than one line of play is optimal for each player. :))

Enjoy! :)

Well, nobody bit. :(

It is actually hard to go wrong, in the sense of failing to end up with Black winning by 1 point. However, the problem is trickier than I thought.

This is a Castle Game between Inoue Dosetsu (White) and Yasui Chitetsu. This was a time of esoteric knowledge, when each go house guarded its secrets. There are indications that House Inoue had a better grasp of the endgame that House Yasui. Certainly Dosetsu seems more sure-footed than Chitetsu. :)

Nice problem. Thanks Bill!

I was always off by a point, because I missed the required White prophylactic in the lower right corner. Dagnabbit.
