Q9s - headsup with button

[Fiddler]

Button is loose and passive, plays more than half his hands. Not very aggressive either before or after the flop.

I open raise in CO with Q [img]/images/graemlins/club.gif[/img] 9 [img]/images/graemlins/club.gif[/img], button calls and the blinds fold.

Flop: T [img]/images/graemlins/heart.gif[/img] 9 [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img]

I bet, button calls.

Turn: Q [img]/images/graemlins/heart.gif[/img]

I check, button bets, I raise, button calls.

River: K [img]/images/graemlins/diamond.gif[/img]

I bet, button calls.

I'm not running so good at the moment and am starting to question myself when it comes to open-raising with less than stellar hands. Should I open-raise Q9s from the CO against a loose passive button? How about the flop bet? Is the river bet too much?

Preflop: standard stealing hand

Flop: good

Turn: lead, call down if raised.

River: easy value bet if you aren't calling down from turn raise.
