10/20 - OOP, 3bet by LAG, missed bets?

[Hectathrill]

Hi, this is my first post here ... thanks for patience in advance. Just wondering if some people could give me advice on a hand on which I think I missed a few bets.

I'm in seat 6, playing a little more aggressive than usual. LAG is in seat 10, capable of raising any 2 cards & 3-betting with any ace/any pair preflop, jams the cheap streets but slows down on the turn/river. Seat 8 is a lesser LAG, everyone else is tight passive - result is that most pots are contested between the 3 of us.

I raise UTG, folds to Villain in seat 10, Villain 3-bets, folds to me, blinds fold, I call.

(Flop: J[img]/images/graemlins/spade.gif[/img] J[img]/images/graemlins/heart.gif[/img] T[img]/images/graemlins/club.gif[/img], 7.5 small bets)
I bet, Villain raises, I call.

(Turn: K[img]/images/graemlins/diamond.gif[/img], 5.75 big bets)
I check, Villain checks.

(River: 5[img]/images/graemlins/heart.gif[/img], 5.75 big bets)
I bet, Villain calls.
