I'm coming around to Renton's side. We raise this flop with a very small range and only get it AI when we're behind, I'm with you there Renton. However, if we never raise this kind of hand on the flop, or weaker draws, we have zero balance for 33 and A3. You could argue that we don't even need to raise those hands though because flush draws make up an infinitessimal part of his range utg, and I would have a hard time disagreeing. So we may never want to raise this flop. The only downside I see is that we'll occasionally give up on the turn to second barrels from hands we could have gotten to fold on the flop with a raise. Good thread.

edit: If we don't raise 33/A3 on this board and heart hits the turn, we'll lose action from AK, so I think we still want to raise those. So I'm back to the no balance argument. Renton, do you think this is a spot where we don't need balance because villain will always think we're capable of raising a flush draw here and get it in with AK?
