Live tournie, blinds are 100/200, I have 35k, average is like 8200 and villain has 17/18k.
Villain is a rich businessman, talking about recent business trips to Dubai, New York and Norway. He is wearing carky three quarters/polo tucked in, white socks and sandals.
My image is very very loose, I've 4bet shoved 3 times in the first 2 levels. Since we came back from break (5 hands) I've opened every hand cbetting and taking it on 3 occasion, 4betting once, other time was the previous hand against same villain.
Previous hand we had got it all in with 66vhis AKss and he had doubled up. In this hand I had raised to 400, he had 3bet to 1000 and we got it all in on a 752ss flop and he hit a flush on the river.
In this hand I raise from utg+1 w/

to 500, villain raises from sb to 2500 and we flat.
Flop is

. He looks at board and checks, I check behind. Turn is

and he bets 5000 quickly. I call.
River is

and he thinks for about 2/3 seconds and Jams for 8300.
Whilst I'm tanking I ask if he will show and he sais yeh definitely. He is shaking a little bit and keeps eye contact with me for the whole 2 minutes +.
Not sure whether to give my own rationale, but my thinking was that he didn't have many 9's in his range that would 3bet pre and then check the flop and 5k pot bet the turn. If he had a set/2 pair I thought he'd at least think about checking. I am are I beat very few hands here, and most hands he is bluffing with are beating me too.
Thoughts?
