Did I play this right?

[Baby Mantis]

I would of 4 bet the turn to see where he was at. Then bet the river for maximum value. He was raising a lot and I was not convinced he had a J on the flop. I def. did not think he had 2 pair or trips. This is the results - villian (small blind) mucked [9c Js]Seat 6: hero(big blind) showed [8s 6c] and won ($22) with a full house, Sixes full of Eights
