Played good?

[rochaldinho]

10-handed: I'm in early position J[img]/images/graemlins/diamond.gif[/img] J[img]/images/graemlins/heart.gif[/img] , raise 3BB. Button(an average tight player) limp and BB limp... Flop: A[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/heart.gif[/img] 7[img]/images/graemlins/club.gif[/img] check, check, check. Turn: T[img]/images/graemlins/spade.gif[/img] I check, button bet 2BB on a 9.5 BB pot, big blind fold and I call because I thought he hit the turn. River 6 [img]/images/graemlins/spade.gif[/img] . I bet for value 4 BB on a 13.5BB pot and he raise to 8 BB. I thought he had at least the A so I fold. What do you think? Must call here? Or save money??
