I just saw the post about your new idea for recommended HH formats. I like the idea so here's my stab at it:

What is a good postflop plan after 3betting a polarized hand, OOP, to a mostly unknown positionally aware Tighty & getting called?

Say hero has T9s & flops medium strength hand with no draw
Flop comes: K97s. T42r
How about a whiff: AK7s
