Pepper_W,
Wow!..Relax, I was only making a suggestion on a subject that I have thought about from time to time. I've never enforced such a rule, because, it isn't one. Let the players bet and raise all they want with the nut straight on the board. That's fine.
I will however, disagree with you when you accuse a dealer of taking sides because he reads the hands of players at the showdown. Are you telling me that you don't want the dealer to read your hand at the showdown? I've got news for you, if any dealer failed to correct any mistake, from any player that properly tabled their hand, I would have a nice talk with him or her, and it might result in some time off.
There are dealers that do things right, and there are dealers that can't seem to get it right. I'm talking about a good dealer that knows what to do in all situations, and one of the functions of a good dealer is to read all hands that are tabled at the showdown, whether you like the idea or not.
I also question what you are referring to when you said: "We make our profits from other players making mistakes." I hope you mean that they make a bad decison by folding the best hand when you bluff. Other than that, the best hand should win the pot.
