Vert Stack with a forehand force
Back of the stack initiates a deep cut
Stack shuffles up to fill the open spot.
Cutter changes direction and cuts under
Clear back to the stack, but do so at full speed. You want to free up the space as soon as possible, but there's also an opportunity here too
If the cutter's check overcommits to the under cut and the cutter is able to create separation with this slashing cut, the handler can hit them with an inside flick
This opens up the opportunity to attack the breakside with a continuation from the stack
