Hi guys so I was playing yesterday this live game $5/$10, was sitting in the big blind with a couple of red Jacks. 

Villain sat down at the table recently, young white dude havent shown much aggression the few hands hed been playing. 

So everyone folds, he raises to 30, I 3bet to 80, he repops it to 220 I call

(440)

flop

8c8h4h

he continues for half pot betting the same amount as his 4bet. 220

I call

(860) 

8c8h4h  Ts

he checks, and I check back (mistakenly???)

River A of spades. He bets half pot and I fold.

thoughts?
