Playing 1/2 live, games plays pretty loose/passive game.  Fairly new to PLO, done quite a bit of studying but not a ton of experience. I feel I can definitely beat THIS (live) game, but still need work.

Hero position is CO, effective stack is starting stack 500.

UTG+1 Opens to 20

MP Calls

Hero CO (KcQcJh9h) raises to 65. My image is tight aggressive, games been going 3 hours I have 3bet once, and shown down maybe 3-4 hands.

BTN Calls, BB Calls, UTG+1, Calls, MP Calls, Pot to flop $325

Flop: Kh9d5d

Checks around to HERO.

Thoughts, table is playing fit or fold post flop, I view my options as checking to see a "safe" turn if BTN checks or if BTN bets get it in and hope to hold, or bet/call. I thought bet calling was my best option I had a little over pot sized bet left and was happy to just take the $325 if everyone folded. 6 ways I feel anyone would have lead a set. 

Advice on all streets? If we check through and the turn is a black 2-8 what is our plan?
