Taking conrol and losing position?

This post is a follow up on the previous thread about defending from the SB against a button's open raise. My general approach to the situation is as follows:


3-bet almost all hands that I'm going to play and then bet basically any flop that comes (assuming that BB folds and button calls, which is the usual sequence of events). I think that that approach is pretty common, but as I was sleeping in class today I realized why I feel so uncomfortable doing it.


Since my bet on the flop is an auto-bet, it gives the button "last action" on the flop. In contrast, if I just call preflop, the button's action on the flop becomes pretty close to auto-bet (far more so if BB folds), which gives me effectively "last action" on the flop. It is in this sense that taking initiative by 3-betting preflop makes me more "out of position" on the flop.


What do you all think about this?
