Party 2/4 villian in hand is loose passive. I'm in the BB with Q [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/club.gif[/img] three limp sb calls i check five to the flop of Q [img]/images/graemlins/diamond.gif[/img]Q [img]/images/graemlins/spade.gif[/img]9 [img]/images/graemlins/spade.gif[/img]. SB checks i bet all fold except last limper who calls and SB folds. Turn is an offsuit brick i bet he calls. River is the 8 [img]/images/graemlins/spade.gif[/img] should i check/call, bet/fold or bet/call?
