2/4 nl deep play-along, interesting spot

[Surf]

2/4 nl, 800 eff stacks.

utg folds, I raise A[img]/images/graemlins/club.gif[/img]K[img]/images/graemlins/diamond.gif[/img] to $16 from the HJ, co (fish) ccs, button reraises to $70,
folded back to me.

Some info on button:

He's kind of a lagtard, 45/20ish, and i've seen him 3bet a wide range of hands, stuff like 77-TT, AJ, some suited stuff - things he should probably be seeing a flop with given how bad most of the other players are at this table. He's squeezed in similar spots before without getting caught. Arguments for calling? Reraising?

Hero...?
