Missed check raise on the flop and now I have no idea what my opponents have. EP limp, so could be anything and I am extremely confused why Im being called but not raised.

River: ($135) Q[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets $85</font>, <font color="#CC3333">UTG+2 raises to $170</font>, MP3 folds, Hero calls $85.

Now I dont see why I would be beaten here but I cant think of any hand Villain could have that would call my all in that im beating. If I raise whatsoever Im pot committed to an all in and I have 500 left, I didnt want to go broke to QJ or QT which makes the most sense to me here aside from a ridiculously slowly played AK/98, a set seems almost impossible.

How bad is this just call with the third nut?

Final Pot: $475
