Template IV2-k is a 4th row edge template with 2 stones.

Red can guarantee to connect the stone marked "↑" to the edge. Red can also guarantee the other stone to be connected to the edge (using the ziggurat template), but not both stones simultaneously.

(From Mike Amling, see: www.drking.org.uk)

Defending the template

Red has two threats:

A

and

B

using the ziggurat.

For a blocking attempt, Blue has to play on one of the overlapping fields:

xy

If Blue moves at x:

126453

Red is connected by III-2-b.

If Blue moves at y:

4213

Again Red is connected by III-2-b.
