Another Number
   

The following position chills to -1/2 (1/2 point for White).

[Diagram]
Diag.: -1/2

[Diagram]
Diag.: Black first

If Black plays the result is 0. That chills to -1, because it costs Black a point to make a play.


[Diagram]
Diag.: White first

W 1 reverses?. The result is -1, which chills to 0.



The chilled game looks like this:

                   { -1 | 0 }

In CGT that equals -1/2. That's no surprise. Go players already knew to count that as 1/2 point of White territory.
