Raise him now or raise him later

20-40 10 handed live

Hero has a strong table image -- playing few hands and aggressively when he does, winning almost all showdowns, showing down premium hands. Villain is an unknown and is not necessarily aware of this as sat down a couple of orbits ago or not necessarily aware at all.

Villain open raises in c/o. Hero 3 bets otb w K [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/club.gif[/img]. The blinds fold and villain 4 bets. Hero just calls (4 bet cap but no cap h/u). The flop comes all rags w/ two diamonds. It goes bet call. The turn is K [img]/images/graemlins/diamond.gif[/img]. Villain bets. Hero...?
