With 100bb effective stacks, it is folded to Villain who opens {22+,ATs+,KTs+,QTs+,JTs,AJo+,KQo} for 4x. It's folded to Hero in the big blind with A9s.

Question 1: If Villain continues against a 3-bet with {TT+, AQs+, AKo}, is a 3-bet bluff to 12bb profitable?

Question 2: Assuming Villain calls our 3-bet with the entire range given in question 1, how often does he hit top pair or better on a flop of Q94r, assuming the queen is not the same suit as our A9s?

Question 3: What hand(s) can Hero 3-bet here that will have the most fold equity?

Edit: You can't do this correctly if you have to use PokerStove for any part of it.
