Definitely three-bet the flop. You are ahead here quite often and the raise is for value. Also, the guy in the middle is quite likely to have called with overcards, so you want to face him with two cold now to get him out and protect your hand. You can't wait and go for a check-raise on the turn because the flop raiser will check often, either because he has a draw and wants a free card or because he has a crappy pair and gets scared by a big card on the turn.
