Ladder escape fork

From HexWiki

A forking move which creates a ladder escape.

Example

In the following position, Red has no edge template.

		a		b		c		d		e		f		g
1
2
3
4
5
6
7

The only option seems to be a ladder.

		a		b		c		d		e		f		g
1
2
3
4
5
6
7

However, pushing too much the ladder is useless, and it actually enables Blue to win.

		a		b		c		d		e		f		g

Red needs the two pieces at the top right hand-corner of the board. Red pushes the ladder just enough to use a ladder escape fork. This pivot piece threatens to connect to the top group and acts as a ladder escape as well.
