2nd set on river - standard fold?

[Burdzthewurd]

1/2 Limit OH8 on Interpoker

4 callers pf, I complete in the SB with Q [img]/images/graemlins/diamond.gif[/img]T [img]/images/graemlins/diamond.gif[/img]T [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/club.gif[/img] (eh not great, but game is either super-tight or very loose-passive), BB checks

Flop comes J [img]/images/graemlins/heart.gif[/img]5 [img]/images/graemlins/diamond.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]

Gutshot straight draw and 3rd nut flush, meh, I check, checked around

Turn is T [img]/images/graemlins/spade.gif[/img]

I bet, BB folds, 3 calls

I check, guy in MP bets, Crappy-loose player calls, CO raises, easy fold? Am I going to see 34xx too many times here? I doubt anyone has 89xxx, they're raising on the turn. Could this just be A2xx vs. A2xx? Gah, I hate the sandwich raise from nut lows
