Thanks to the mathematical realities of card counting it has been shown to work. By keeping careful track of what cards are left in the shoe, a card counter is able to place larger bets when there are more high cards left to be dealt, and smaller bets then there are fewer high cards left in the shoe. That being said, card counting isn’t for everyone and it does require a certain amount of practise and dedication. You also need to work hard at not getting caught. There are certain characteristics you need to have in order to be successful. For example, you have to be a stickler for details and be able to pay close attention to the cards being played, without making it obvious that’s what you’re doing. You also have to be disciplined and able to keep your cool.
