reckoning dictionary - 5 -

This is the basic shape for our next shape.

I will focus on real game situation.

W 9 / B 10

W 10 and a half right has each other.

B 8

B 7 2/3 ( because White has the right of 1/3 )

So,
1. W 9 B 10
2. W 10 B 8 or W 10 B 7 2/3

the average of 2 is W 10 B 7 5/6

the average between 1 and 2 is W 9.5 B 8.91666666.......

But..... if you are not a genuis, ( me as well ) you might want to find the easy way... thought it is not rather accurate.

So, plus 0.5 each other first.

Second, black territory ( 0.416666666... ), let's ignore!

Conclusion : White 10 / Black 9
