215 Flush on paired board

[Pasterbator]

Everyone's been saying that you need to play the early game well to make money at the $215s, so i assume that means playing good drawing hands in LP. So i don't mind the call preflop.

UTG's cold call on the turn scares me. It looks like he could have missed a limp reraise PF with AA and filled up on the turn. 88 is another possibility. If hes a good player, i can't see him limping UTG with any flushes.

Anyway, I think you're supposed to fold this (tho i wouldnt at the $33s) Would you have bet if he checked the river to you? How would you react to a checkraise?
