Many of us have probably had the same experience I have had. You lose several hands playing good basic strategy, and, AFTER the hand is over, you receive commentary from the dealer as to why your play was wrong.
In one instance, I lost a hand that in which I played basic strategy, and I commented that I had made the correct play. The dealer went so far as to say, "Who won that hand?.........then you didn't make the correct play."
It's amazing how many telepathically gifted dealers there are. They seem to know AFTER THE HAND IS OVER the perfect way to have played a hand. I felt like telling this gentleman, "Look, would you please just deal the cards. I appreciate your uncanny ability to predict AFTER THE FACT :), but please just deal the cards." How do you all deal with dealers who have been dealing for 500 years, hate their job, and are more than willing to tell you (and in so doing, waste your time and therefore money) why basic strategy is the wrong way to go.
