in endzone. someone calls "Vert Stack!" Open side handler (H3) lines up at a 45 degree angle behind the thrower. Having H3 as an option for a dish can lead to an easy break side goal.
7 and 6 make cuts to force and break side respectively. H3 pushes defender away.
Let's say nobody gets the disc. 5 and 4 move up. 7 and 6 go to bottom of the stack.
H3 sets back up and 5 and 4 make same respective cuts as 7 and 6.
Yay, in this case, 5 gets disc. Score!
