NLTRN - Sucker straight in 3bet pot

[soop]

Villian raises most of the time out of the SB. He's pretty loose and I suspect he's floats sometimes but I haven't called him down yet. I've played pretty tight so far and this is the first time I've 3bet.

I'm having a tough time making sense of this hand b/c my gut tells me this is always an ace, but most hands with an ace either push or fold that flop (right???)

Also, is check-folding the flop or conversely pushing the turn better than the line I took?
