Step 1

A setup breakside even. B setup openside 45, disc middle.

Step 2

A is thinking 'WE NEED POWER POSITION, I AM AGGRESSIVELY GOING TO CUT UPLINE AND BE OPEN AT STALL 5'. That means start the cut before stall 5.

Step 3

A's ideal goal is to be open upline at stall 5. Thrower doesn't need to square up to see this cut, they should see it coming in their periphery while scanning downfield, and QUICKLY make the decision of whether or not they're going to throw it. If they throw it, YAY POWER POSITION! If they don't throw it, square up and engage B.

Step 4

B technically has 2 options, but most likely outcome is blow-by.
