one of those hands u just cant lay down, I would put him on two pair or maybe even a set too. betting to protect from draws. ya sure its possibly that he got the nuts. but u cant just lay down tripped aces. at least I cant =) not with this little information on the players, maybe if he had slowplayed for a trip or straight, then got it and bet big, MAYBE. or maybe not. id prolly call anyway since ur so deeply involved.
