There is the chance for white to make 1 cross.But, if it's black turn, there is nothing.
So, there EXISTs a half white cross.
And if it's white turn, white can create 1 cross. If it's black turn, black can terminate a half white cross.
Therefore, its value is 1.
Conclusion : There exists a half white cross. / Its value is 1.
Then, I'll prove it.
There is two groups of a half white cross below.
So, total white cross is - a half plus a half - 1.
Is it right?
p.s My English ability is some poor, so please point out my fault in using English.
I will rightly modify it. Thank you.
p.s I think that positional judgement is very very very important to fight to the finish in minuteness.
But its technique is nowhere! Even if Korea.
It seems some boring, complex, and so on... but, think about Lee Chang-Ho 9D in Korea.
His best arms is positional judgement ability!
And I think if one is strong of positional judgement, his other baduk skills follow.
Because baduk is the game of selection.
If I am of great advantage, I will concede and be safe to keep victory.
If I am of some disadvantage, I will shake ( "shake" means "make complex" ) all on the board to capture the chance of victory.
How about your opinion?
