Inducing the Bluff, KK hand

[jsnipes28]

About 4 hands earlier i had flopped Aces up and then folded to a gigantic raise by villain on river. He told me "2pr" in chat box and i told him that i folded A's and 8's. Anyhow, on to this hand.

Hero checks, BB moves all-in for $35. Hero calls.

is this a bad call or is this the right move to make? My thinking was that since he had just pushed me off of the best hand that he would think he could do it again. Also, the way he had been playing i could expect a raise on 3rd or 4th if he had a flush draw. Thoughts, Comments.
