100BB effective, you are in the BB.
Scenario 1:
Villain open-shoves with a range of any pair and any two broadway. This is pretty easy to solve if you don't already have this memorized.
Scenario 2:
Villain raises to 3BB. It is folded to you. If you 3bet, he will shove with 100% of his range (or call if you raise all-in).
Obviously, raising with any hand you would call with in scenario #1 should be +EV, but is it the most EV play for all hands?
So, my question is, what should be your flatting range in scenario #2? This can include hands you would flip with in scenario #1 and hands you would fold.
