should this river be raised for value

[SenecaJim]

Hero has 5 [img]/images/graemlins/diamond.gif[/img]5 [img]/images/graemlins/heart.gif[/img] on the button. 5 limpers, hero calls, blinds stay.

Flop 2 [img]/images/graemlins/diamond.gif[/img]3 [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/spade.gif[/img] Checked to LP3 who bets, CO calls, hero calls, all others fold.


LP will lead out frequently on flop and turn with any piece so really don't know what he might have.
CO has been very loose, hit 2 flushes so far, one with J4s and one with T5s.

Turn is a blank. LP bets, CO calls, ( 7BB ) hero calls.

The river is the 4 [img]/images/graemlins/diamond.gif[/img] LP bets , CO calls, hero ?

Call or raise here?
