Overview: 3 goes under, 4 goes away, 1 goes under, 2 is heads up and plays the continuation. The options below are just variants OPTION A: Set up a split stack. Off a stopped disc (bricked pull), defense will probably set like this if they're smart.
3 checks out, then under
4 pulls out (or checks middle) then deep If we hit 3 here, that's fine, they can dish to A for PP huck, or they clear to the left rail
4 goes deep
1 slashes, 2-4 think about filing back into a ho stack
2 can continue for 1, or we just do normal ho stack things.
OPTION B
3/4 do same thing
get it to 3
3 jacks it off to 4
OPTION C
same cuts
as before
but none work, so look dump
reset disc/stall/stack
boom, ho stack
