did I make a boo boo?

Here's one of those hands that just leaves me in disbelief. Did I play it incorrectly? the SB has been aggressive ever since he built his stack, raising with any paint, but looking back, he folded a lot to my turn bluffs and semi bluffs. Should I have known I was walking into a trap? Was my check on the turn, trying to set a trap myself, wrong? I bet the flop HOPING for him to reraise me thinking I was bluffing at the 9's, because I would always take a stab at the pot, and if reraised I folded to him. It was all working out till the stupid 6, even if i bet the turn, i dont think i would have folded if a 6 hit.... thanks in advance.
