Edge templates with a bridge

In the edge templates below, both stones are guaranteed a connection to the edge.

Fourth row template

This looks like template IIIa, combined with a two-bridge. It may seem odd that the template works, since the two-bridge and the template IIIa overlap. The strongest attacking move (Blue 1) is therefore obvious. After Red 4, the red stone at the top is connected to the bottom via two-bridges.
