I see. Then my idea doesn't work as intended.

Anyway your idea is a major part of the solution but OC some more work is needed to really find it.

Ten days ago I proposed in https://lifein19x19.com/viewtopic.php?p=279399#p279399 a rather difficult problem with a superko and a large black territory not so easy to handle.
Maybe it's time to help you a little and I can propose the following simplier position on a small 9x9 board.

AGA rules. No komi

In this position you can count 33 black stones and 33 white stones.
What is the best sequence to reach the best result for both?

To my point of view the solution is still not so easy to find and the resulting position is extremely surprising. I like very much this problem.
Because all subtilities in this problem are present in my previous problem it is certainly a good idea to firstly find the solution of this problem before resolving my previous one.

B+5 but it is not satisfactory for black. You have to find something better.
