you can defend either way. i would typically call against a hyper-aggro who fires the turn a lot. i'll take my bluff and semibluff equity since he'll be firing on vapor a good percentage of the time and will be sorely tempted to fire again. against a flop hyper-aggro who does not fire much on the turn (and there are a lot of those on UB), i like the raise. most will call you with a draw then checkfold the turn, and you have the As redraw if the flush gets there and he fires into you.

or just reraise preflop.
