Red should go here:
The Red 1 hex is connected to the bottom, and threatens to connect to the top through either one of the "+" hexes. Thus these are the only important incursions. An incursion to the right of the number 1 hex is important only in connection with the two indicated here, and will be seen in the treatement below transposed into the sequel.

Red threatens to play at "+" points above, with these templates:
We need only consider the intersection of these templates.
