FULL RING IS FOR LITTLE GIRLS

[MTBlue]

10/20 at the Bellagio.
We're playing 9 handed.
Main Villain has 4Kish, I cover.

He has been playing passively and tightish postflop. I've won a couple of biggish pots against him in the last hr. He isn't visibly tilted but its probably irritating him.

I raise UTG+1 to 80 with Tc9c. 4 people call.

Flop 8c 8d 4c Pot (430)

I check? Villain bets 240 directly behind me. Everyone folds to me.
I call?

Turn 5c Pot (900)

I check? He bets 500, with 1 chip. This is a big bet for him. I call?

River 9d (1900)

I check?
