$215 middle pair, flush draw, bkdr straight, Too Pretty To Let Go?

[MadScientist]

Lots of lines seem attractive to me here. The overall question is are you willing to get it all in? Was my flop lead good, even against a bad scenario, say limped AA by the CO, I have very good equity, but I am slightly behind. However, after my flop lead, pot odds make up for any disadvantage I may have. Also, I could be ahead of A high right here...
What would you do and why?

Yeah me too...I actually can't think of why and give reasoning but this is a natural checkraise for me.

Id fold PF, you only have ~15 BBs

[vinyard]

If I complete PF (I rarely do) I am CRisng'/pushing this all day

Seems impossible for him to both have a better made hand than you and a better flush draw. 3-bet all-in on the flop unless you think he must have a strong made hand to do this and is very unlikely to fold.

Or not.

I'd fold preflop.

i would go for a CR push on the flop. the way it was played tho, get it all in on the flop the 2nd time.

seeing as how you didnt commit urself on the flop, the turn is very difficult to play and you are now on the defensive. check call a decent bet and fold to any real bet.
