A dubious play?

[DocHollyday]

10/20$, 7handed

I get A [img]/images/graemlins/heart.gif[/img]9 [img]/images/graemlins/heart.gif[/img] in the BB

UTG limper and a very loose player raises EP. All fold, the UTG and me call.

Flop: 5 [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/heart.gif[/img]6 [img]/images/graemlins/club.gif[/img]

I bet my guts-shot and my overcards, call, raise, call, call

Turn: 7 [img]/images/graemlins/diamond.gif[/img]

Check, check, bet, call, call

River: 4 [img]/images/graemlins/diamond.gif[/img]

Check, check, bet, I raise, limper folds. EP calls ALL IN shows 88 for a set and we share the pot.

Not too sure about my play, but I like my river raise (I did it only because the EP had 2.50$ left) for the UTG's share of the pot. Please comment!!
