AQ Big deision final table

[pearljem]

My local live tournament.Im chip leader with 44,000 at the final table in the BB with AQo.7 players remain,blinds are 3000/6000.Its folded around to the button who limps in,SB folds.Button has 38,000 and is my biggest treat.Average chips about 20,000.I raise 15000 and he moves all in for 17000 more.The pot is 47000.So im getting 2.7 to 1.I have a pritty solid read on this guy and im sure he dosent have a big pair,so im getting the right odds to call.if i win i have a 4 to 1 chip lead.I call and he shows J9s.Terrible move i know!!!Anyways he wins with a straight and im crippled.i think my biggest mistake was not moving in pre flop if i knew he was weak,what do u think?
