Ladder escape fork
From HexWiki
A ladder escape fork is a move that creates a ladder escape while also threatening another connection. It is a kind of double threat.
Example
In the following position, Red has no edge template.
The only option seems to be a ladder.
However, pushing the ladder too much is useless, and it actually enables Blue to win.
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. Piece number 3 is called the pivot piece. It threatens to connect to the top group and acts as a ladder escape as well.
