97o Live 2/5 game in Blackhawk, Co

[Bilgefisher]

Just got done playing live 2/5 poker in Blackhawk. I'm on the button 7 limpers. I limp behind with 9[img]/images/graemlins/club.gif[/img]7[img]/images/graemlins/heart.gif[/img] The bets on flop turn and river are anything from 2 to 5 dollars depending on whose betting. Only once in the last 3 hours has anyone bet anything other then 5 dollars on any street. The blind is anything from 2-5 dollars as well and is always 2 dollars exept for one older guy who posts 3 dollars. In this case its 2 dollars.

Flop comes 5[img]/images/graemlins/heart.gif[/img]8[img]/images/graemlins/heart.gif[/img]9[img]/images/graemlins/heart.gif[/img] It gets checked around to an extremely loose player in MP who just sat back down and really doesn't seem to have any rhythm to his play style. Could be betting air, could be betting the nuts. He bets, it gets raised to $10 (2bb) by a fairly tight passive player although I have seen her play draws very aggressively. She is directly to his left.

Folded around to me with 4 to act after me now. Whats my move?? The table will likely have 3-4 see the river no matter the action.
