Basic vert stack formation. Slightly off-center stack to give us more breakside space to make throws to. Not too staggered otherwise we give the D a heads up what might happen.
1 and 2 in stack clear out almost simultaneously. 1 goes force. 2 goes break. You can hit 2 on the break if it is there. 3 in the stack sets up a breakside cut.
Primary look is to hit 3 coming. 2 in stack is dragging deep by this point. 1 in stack chills and keeps space clear.
What we want is to walk this up breakside. So once 3 catches it, 4 is an immediate breakside cut while 5 sets up a cut to see what happens. Getting that breakside continuation to 4 makes this play really go.
If we get it then 7 looks to cut back breakside while 2 breaks for the opposite corner.
