limped pot flops straight

Villain was completely unknown. Was about 1/2 stack when I got to the table and doubled up within a couple hands with a set vs table donk's weak top pair. Is the flop 3bet a good size? His flat makes me think maybe flush draw, weak overpair, I doubt its a set. Is the plan on the turn bet fold? Bet shove? Check call?

Hero?

$4 on flop. 3bet bigger. As played I may even c/f depending on sizing, I think sets/2pairs are checking behind a lot and then we can get value on riv.

I LIKE B/F against these half stack buyin guys.

Why pot flop? That's not something I'd considered. I guess draws will call it, but it folds out a lot that might call a smaller as well?

I meant to bet about $3 on the flop but was messing around with Full Tilt shortcuts and was timing down and just hit bet. The flop 3bet might have been a little small looking back at it.
If we bet fold turn, thinking about $29 or so?

yep, he's calling $12 into $45 so a fd would call expecting to get some more $$ out of you if the flush hits. Sets are also in range and aren't folding to a bigger bet.
