PJ step 2. the most small value (2) /baduk/

There are triangle marks. It means decided-territory.

Black will do like this and created 1 black cross.

White will do like this and created one third black cross. You already knew if only you read "the most small value (1)."
So, there exists two thirds black cross.
If it's black turn, there created 1 black cross. The numeral difference is one third.
Therefore, each turns earn one third and its value is two thirds.

Conclusion : Exists two third black cross. / Value is two thirds.

There is a convenient way.
Black will want to play elseway instead of sequence 2.
Of course it can!

But anyhow white do 2 sequence, then, black must do 3 sequence.
Because 3 sequence is bigger than two thirds.
And because reasonal white player thought that there is not bigger one.

PJ step 1. the most small value (1) /baduk/

There is a “ko”.

If it’s black turn, black will connect it by one sequence and there is nothing.
If it’s white turn, white will capture it and connect it later by two sequences and there is one captive.
All sequence is three, and quarrel a cross.
So one sequence earns one third.
Then, if black connect it, there is nothing.
If so, there was already one third white cross.
Bacause black earns one third.
And, each side earns one third, so its value is two thirds.

Conclusion : there EXISTs one third white cross. / its ending game(yose) value is two thirds.

Can you count it?
A exists one third white cross. B and C are as well.
So, there exists one white cross on the board.
