#5 cuts in on the open side.
#4 moves to the center of the field to become the head of the vertical stack and cuts on the break side for the reset if needed.
#1 cuts deep along the sidelines and clears into the stack. #7 will be clearing into the stack but cuts on the open side again for a possible continuation cut.
