50NL - Did I leave chips on the table - turn decision

[NNH]

50NL 6max
No good read on UTG other than that I haven't seen anything out of line. BB is a bit loose PF. I just doubled through him the previous hand against his AA.

I think I left a lot of money on the table in this hand. Thoughts on turn and river?

I bet half the pot here expecting him to fold but would call a push. Remember that you just cracked BB's AA, he is pissed of course and could have a real hand (which you beat all of except the unlikely quads) or could be raising on a bluff.

So you got a perfect turn and 1/2 potted it. I don't like. Push the river, he's not calling your VB with a flush now, but is calling with an ace, and sometimes a 7. If he has a 9, those are the breaks.

bet more on the turn and get most (if not shove) river.
