You could be pumping a draw on the flop or a made hand. I think Q[img]/images/graemlins/diamond.gif[/img]9 is the most likely after seeing the turn and river. 55 is also an option for you until your check on the river. You don't 3-bet the turn with 2pr unless it's JT, and you wouldn't 3-bet the flop with JT.

LP most likely has JT. I'm not sure about EP.

My thought is that the J on the river scared you. There's no reason for you to check to LP if it helped you. If it improved your hand, (i.e. you have J8, JT, 88, 55) you should bet and hope EP gets trapped between you and LP.

EDIT: Forgot to mention the obvious flushes.
