6-max, UTG limps, I complete in SB with A4, BB checks.

Flop is A43, I bet 10, BB raises to 40, UTG folds.

BB is over aggro post-flop imo & I decide I will go all the way with this if he wants & my best chance to stack him is a turn or river CR. We both have about $600

So I call and then check-call a blank turn for 75.

River is a 3, so I give up on the CR & plan to call. He fires out 150 and in going through things I can't see this being worth calling. So I fold it.

Thoughts? I don't like my line. Re-raising flop & firing big at the turn seems an option in retrospect although I do give him a chance to drop something like A3/34 before he gets committed. Other lines? Maybe a donk bet on the turn?
