Turn/River play?

[Yeknom58]

Party Poker 2/4 Hold'em (10 handed)

Preflop: Hero is UTG+1 with Q[img]/images/graemlins/diamond.gif[/img], Q[img]/images/graemlins/club.gif[/img].
UTG folds, Hero raises, UTG+2 folds, MP1 folds, MP2 calls, MP3 folds, CO calls, Button folds, SB folds, BB calls.

Flop: (8.50 SB) J[img]/images/graemlins/diamond.gif[/img], 2[img]/images/graemlins/diamond.gif[/img], Q[img]/images/graemlins/spade.gif[/img] <font color="blue">(4 players) </font>
BB checks, Hero bets, MP2 folds, CO calls, BB folds.

Turn: (5.25 BB) A[img]/images/graemlins/club.gif[/img] <font color="blue">(2 players) </font>
Hero checks, CO bets, Hero raises, CO 3-bets?
The CO seems like a loose/passive ABC player so I'm positive he woule play KT, the problem is I'm about 50% sure he wouldn't 3 bet with a hand like 2 pair/Pair+flushdraw? So do I cap or call the turn. And what's my river play assuming I don't fill and another blank falls on the river.

First of all I dont like the ceck on the turn unless you were certain he would bet, as for the turn I would cap it. Once the river came Im not sure if I would check call or come out beting. I think I would bet out and call if raised but I have mixed emotions about it
