give me a better line

Opp is 16/14/4 over a decent sample and is capable of playing back at me. I think this is standard, but is there another line that will get his stack? I can't give cheap cards with draws on the board, but WTF does he have? It can't be just AK--maybe TT/99? Not sure what CO could have here except a smaller PP/FD of another suit.....but I didn't want this three way.

PF call was okay too due to stacks, I think.

Could he have an overpair or maybe AQ? Unfortunately your poor relative position to him means that even a call will indicate strength, but then the CO may just call and maybe catch a card and then you need to fill up. There's probably not much you can do to get his stack in here unless he has a straight and flush draw or a bigger set I think.

So the only other play is to call, and hope that the CO either folds or raises or a flush/straight cards doesn't hit. I prefer raising but I think mainly because I don't like folding sets

I like pushing, makes it look like you have a draw on this board moreso than a set.

id open push this flop and try to look like a fish. (if he has over set then meh)

Pre-flop is close. Flop is goot.
