prolog : real basic of Positional Judgement and ending game /baduk/

Can you do this positional judgement?

Yes, black is 18, white is 18, so even.

It’s very easy, because all territory was desided.

Then, how about this?

Is it easy too?
It seems very difficult, because of non-desided-territory.
However, I will explain the method step by step.

p.s It contains positional judgement and ending game, but main subject is positional judement.
