If you know for a fact he has the flush, then it's an easy fold. But that's beside the point, because his range is much wider than just flushes here (especially since you have the A[img]/images/graemlins/heart.gif[/img], to wipe some flushes out of his range).

I might even bet a little less on the turn, to induce this push a little more often.
