I screwplay the turn here pretty often. I doubt a tough player is calling the flop to either fold the turn unimproved or call the turn with some sort of draw, so bet/bet with A-high is a pretty dumb line unless you think his turn raise will be a move often enough that you're willing to pay the 3bb to get it to showdown. I don't find myself in this spot too often so I can't really give you my frequencies here, but I'd call more often than I'd 3-bet, and I'd 3-bet more often than I'd fold unless he's the type that virtually always waits until the turn to raise a pair in a blind battle then I'd reverse the order.
