Introduction
Tom's move is a trick that enable a player to breakthrough a second ladder. It's name originates from player tom239 who invented it on Playsite (according to Glenn C. Rhoads).
Minimal example
In this diagram Red wants to connect to the bottom edge.
It looks impossible to use the single stone on the fourth row as a ladder escape. How can it be done? By using Tom's move:
He pushes the ladder until he is right underneath it, and then he plays at 5.
Now the situation is completely identical to that in the Double ladder on 2nd line Escape. Blue's natural defense is to play at (+).
Now Red´s two pieces at g6 and h5 are connected to the bottom edge via edge template IV2b, and his ladder can connect to those pieces in two different ways, by playing in either of the starred cells. Red is therefore safely connected to the bottom edge.
