K4o turn check-raise

UTG is horrible calling station, but raises good hands. BB is UKNOWN.
4 handed 15 30.
UTG limps someone folds, I complete with K [img]/images/graemlins/club.gif[/img] 4 [img]/images/graemlins/diamond.gif[/img] then BB raises, UTG calls and I call.
Flop J [img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/diamond.gif[/img] 4 [img]/images/graemlins/club.gif[/img] check-bet-call-call

Turn is 7 [img]/images/graemlins/heart.gif[/img] check-bet-call-check raise-call....

River is 3 [img]/images/graemlins/club.gif[/img] bet-fold-call

I wanted the BB to fold the turn so I could play with UTG.. no such a luck, so I thought I must bet the river.

Maybe I should just fold prelfop and avoud this crap [img]/images/graemlins/tongue.gif[/img]
