I understand why casinos kick out card counters, the casino wants to make money and card counting is “cheating”. But if you are able to do it all in your head, is that not the same as being really good at poker? Knowing whats left in the deck and estimating your opponents cards based of that info and by reading your opponent. How do you prove counting vs skill? Is it just a way for casinos to weed out people who would take a lot of money?
