Live 1/2 cash at DTD. Reads: villain is a fishy Chinese guy in his 20s. Not played much with him. He sat with 100but the table min was 200 so he had to go to the cash desk, came back with 600 and sat with it all. Fairly face up standard loose passive post, and very spewy pre. He's been mainly calling preflop, seldom raising himself (maybe because table was very aggro so wasn't getting the chance tbf). I dont know whether he's been paying attention or has a view on me (Id guess probably not) but if he did it'd be very active and aggro.
Preflop Villain (600) raises first to go to 16. One caller (decent reg) in middle position. I call (covering) from the blinds with

. The straddler calls.
Flop (66)

I check, check, vilian checks his cards then quickly bets 30. 1 fold, I call, straddler folds.
Turn (126) 
I lead for 70, villain rechecks his cards (for clubs ldo) and calls.
River (266) 
I bet xx
Thoughts on 3betting pre, calling on the flop, turn lead and how much to bet now.
