77 - Truepoker 2/4 - Rivered Full House

[MainEvent]

Okay, this seems really easy at first glance and perhaps it is but I'd like some thoughts.

I don't have stats on these players but most people on this site are moderately loose-very passive pre-flop while being some what tight-passive post flop.

One loose limper to me on the button, I raise 7 [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/spade.gif[/img]. BB Calls

Flop: Q [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/heart.gif[/img] 10 [img]/images/graemlins/diamond.gif[/img]
Checks to me, I bet . Both players call.

Turn: J [img]/images/graemlins/club.gif[/img]
Checks to me, I check

River: 7 [img]/images/graemlins/heart.gif[/img]
BB checks, MP bets. I do what?

If it's an easy raise, tell me how many people acting behind me there need to be before I just call this in hopes of overcalls. Remember, these players are pretty tight passive postflop.
