Nl50 - turn 2pair but makes flush possible, facing PSB on river

[toxzen]

Read: Villain is a big fish and is my reason for being at the table. He is 75/8/1.8 over 1000+. He plays any two from any position and will cold call a raise with anything. After watching him for a while for someone with his PF looseness he actually plays reasonable post flop. He's still a donk and I don't think he is capable of getting away from top pair, ever. He also either min bets (weak) or psb's (strong). There seems to be no inbetween bet size for him. He is also very chatty.

Action: Flop: maybe bet 4 dollars? Turn: Sucks. I check behind for pot control. I want to keep it small planning on calling a decent sized bet on river. River: Alright, I had to go into the tank here. I've been chatty with villain (i like to chat with my fish as to keep them in the game). Someone at table types "just fold" so I respond with "tough spot". Villain then says "fold, i have a flush". To me this is a tell that he's telling the truth from what i've experienced in the past. But making 2 pair with AK is just so tempting and that PSB is just so nasty.
