QTo from the BB

[BreakfastBurrito]

8/16 Oceans 11. 2 loose passives limp, decent player raises, button and SB call, and I call in BB with Q [img]/images/graemlins/heart.gif[/img]T [img]/images/graemlins/diamond.gif[/img]. Limpers call.

Flop is K [img]/images/graemlins/heart.gif[/img]8 [img]/images/graemlins/heart.gif[/img]4 [img]/images/graemlins/heart.gif[/img] and it gets checked around.

Turn is 3 [img]/images/graemlins/heart.gif[/img] Checked to button who bets, I call, one loose passive shrugs and calls everyone else folds.

River is a blank. I bet, LP folds, button raises and I fold.

What's the proper line here?
