It also gives you the least when he doesnt have an ace. A check call may not tell you anything on the flop, and I dont know if I would play it that way, but on the turn it will definitely tell you something. I dont think you will see somebody fire a second barrel without an ace, I could be wrong though. If he is laggy he may, but even then id be surprised. Him being laggy is even more reason not to bet this flop because you can be fairly sure he will put a bet in with a worse hand.
