System of counting cards in blackjack

The card counting systems are evaluated by two primary factors: the efficiency of betting (Betting Efficiency, BE) and the efficiency of the game (Playing Efficiency, EP). The anomaly of counting systems is that, for most of the time, if you increase the BE, decreases, at the same time, the PE. For reasons of bet, the Ace is a very powerful card, is the primary component of a “blackjack” which is paid 3 to 2. But to play a hand, the Ace is of limited value. How many times have you doubled an 11 and you got an Ace? Now you have a 12: exciting, right? Pull with a 14, you get an ace and all-embracing 15; nothing to get upset, right? Sure, it’s nice to get a 10 and a double ace, but this is one of the few times where the Ace helps in the play of a hand.


The manner in which a counting system treats the Ace determines a lot about the BE and PE of that system. If you need high efficiency betting – as in a game with more decks – then follow a system that counts the Ace as a card “great” if the game you have chosen is a single deck, then choose a system that treats the Ace as a card “neutral” (and keep track of aces with a “side count”, a trick that will teach you later.)

The multi-deck games are beaten primarily by the use of big bets. In short, little bets when the dealer has the advantage and more when the advantage is yours. A counting system with a high BE factor tells us when to raise the bet. In a game with a single deck, a high PE will make you bet less, but you will win anyway.


Do not forget, the casinos know that their games are vulnerable and that is why I am always looking for people who can beat them. There be recognized as a counter can cause your expulsion (“barring”) from the casino. Let me say that what I’m teaching is totally legal, but not all casinos feel the same way. There are no laws against card counting and may be the best card counter in the world, but if the casino does not allow you to play your skills will be wasted.
