KJo on the button

Party 3/6 6-max (6-handed)

MP posts a blind.

I have K[img]/images/graemlins/club.gif[/img]J[img]/images/graemlins/diamond.gif[/img] on the button.

UTG limps, MP checks, CO raises, I 3-bet, BB calls, UTG calls, MP folds, CO calls.

I 3-bet because CO is way over-aggressive and laggy. He has limp-reraised 3 players with K8o. PFR > 35% in this session. The other guys seemed loose but other than that I don't know.

Flop: A[img]/images/graemlins/heart.gif[/img]T[img]/images/graemlins/heart.gif[/img]J[img]/images/graemlins/spade.gif[/img] (13SB)

BB bets, UTG calls, CO calls, I call.

Turn: 2[img]/images/graemlins/spade.gif[/img] (8.5BB)

BB bets, UTG calls, CO folds, I call.

River: A[img]/images/graemlins/diamond.gif[/img] (around 12BB)

BB checks, UTG checks, I check.

About the river, I bet and get called by what? A busted draw with a jack? Plus the pot is big and I want to show down. I don't know.
