I don't quite understand why you would even bother calling the turn. At best, each of your overcards is worth about 1.5 outs each. Actually, they're worth even less because a K[img]/images/graemlins/diamond.gif[/img] gives a possible flush to Villian and an A[img]/images/graemlins/club.gif[/img] gives Villian a different (and more likely) flush. Yes, his aggression could be a bluff or a semi-bluff, but on the turn is pot odds of 4.25 to 1 worth it? You really would need 14.3 outs to call, and I think you have less than 3.

Take this all with a grain of salt; you're a helluva lot more experienced than I am, and I could easily be wrong.
