Step 1

We're set up in a vertical stack

Step 2

Disc is moved upfield to next handler. Back of the stack (7) fakes a deep cut open-side. Meanwhile, front of stack (3) fakes an under cut break-side.

Step 3

7 then comes under, while 3 streaks deep.

Step 4

We should hit one of the two options off this play

Step 5

If no options are available, disc is swung back to the other handler, and flow continues
