Set up in a Horizontal Stack
(2) cuts to the break side while (3) cuts to the force side. (1) and (4) cut deep.
If nobody gets the disc, (2) and (3) clear to the wings, and (1) and (4) fill into the middle. Notice that we made 2 diamond shapes (one on each half of the field), and that (1) and (4) have now become the middle cutters while (2) and (3) have become the wings.
Repeat the cycle. This time (1) cuts to the break side and (4) cuts to the force side while (2) and (3) go deep.
Say the throw goes to (4).
Now it is (3)'s job to make a continuation cut, and (2)'s job to continue cutting deep.
And score if it's there.
Now pretend that (6) decides to throw some nasty break to (1) instead of the force-side throw to (4) .
...
(4) continues his clear while (3) cuts back to the force side and (2) cuts back to the break side.
If (3) gets the continuation, (2) can cut deep.
And score if it's there.
