This article deals with a special case in defending against intrusions in template VI1, namely the intrusion on the 3rd that is not eliminated by sub-templates threats. NOTE THAT THIS PAGE IS NOT CORRECT; THE SUGGESTED MOVE FOR RED IS A LOSING MOVE AND BLUE CAN RESPOND BY PLAYING ON THE SECOND ROW DIRECTLY UNDER THE TWO STONES; THIS BREAKS THE CONNECTION.
Contents
Basic situation
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. We consider each of the two incursions below.
Third-row followup: i4
Figuring out the Must-play region
Red threatens to play at "+" points above, with these templates:
We need only consider the intersection of these templates.
