I'm wondering if I should have 3-bet the flop with such a strong draw and maybe build the pot. It seems like UTG+1 has no plans of slowing down, but how should I play the turn if the action is checked to me? Would betting still be profitable or should I take a free card in the case that I don't make my flush on the turn?

Final Pot: 5.25 BB

I'm not sure if this fold was too tight. I'm just having some trouble dealing with overcards on the flop. The pot and field were small so I thought anything but a fold would not be worth the bets that I might put into this hand.
