Flop checks around. Turn is 5 [img]/images/graemlins/diamond.gif[/img]. Villian bets $5. Hero calls, remaining three limpers fold. River is 4 [img]/images/graemlins/club.gif[/img], completing a nice big blind special. Villian bets $10, Hero raises to $25, Villian immediately goes all-in for his remaining $117. Hero?
