Maybe interesting hand

[Trix]

6-handed 15/30 table.

UTG limps(55/8/1.8(over 100 hands)), MP limps(48/0/0.8(100 hands too)), CO limps(60/9/0.7(few hands)), BTN limps(38/11/2(few hands)), SB folds, I check 9 [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/spade.gif[/img]

Flop 9 [img]/images/graemlins/spade.gif[/img]8 [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/heart.gif[/img]

I check(Should I bet ?), UTG checks, MP bets, CO folds, BTN calls, I call.

Turn 6 [img]/images/graemlins/club.gif[/img], I check(Should I bet?), UTG bets !?, MP folds, BTN folds, I call.

River A [img]/images/graemlins/diamond.gif[/img], I check, intending to call.

I´d like comments on what is the best action on the flop and also whether it´s better to check or bet the turn after the flop check-call.
When I check the turn and UTG bets out, I think I have a fairly easy calldown, so unless you disagree, you can ignore the action from there.
