Since the 1960s, the concept of card counting has intrigued casino enthusiasts around the world. Brought into the mainstream by books, card counting is often misunderstood as a superhuman mental ability. Actually, card counting is just a basic implementation of probability theory. It won't ensure a victory on every deal, however, it shifts the casino's house edge from the casino to the player.
The Basic Idea: The Importance of Aces and Tens
The entire system of this blackjack strategy is based on one truth: a shoe full of tens and aces gives the bettor a massive advantage, whereas a shoe rich in small numbers helps the casino. Large cards like Kings and Aces raise the odds of the player hitting a natural blackjack, which yields a bonus return. Crucially, an abundance of tens increases the probability that the dealer to bust when they are forced to draw.
The Hi-Lo System: Keeping the Running Count
The standard card counting strategy is the High-Low method. To use this strategy, you never try to recall every single card played. Instead, you attach a score to the cards as they appear. Small numbers from two to six are worth plus one. The medium ranks are ignored completely. High cards (10s, face cards, and Aces) subtract one from the count. While the game progresses, you simply keep a running tally the score mentally.
Your count starts at 0 at the beginning of the deck. Calculate the True Count by dividing the running count by the estimated number of decks remaining. Raise your wagers during a high positive count. Bet the absolute table minimum or leave the table if the shoe is full of small cards.
Casino Countermeasures: The Casino's Defenses
While this mathematical approach is mathematically sound, pulling it off successfully in a real, noisy casino environment is incredibly difficult. Casinos are fully aware that these systems work. To combat this, they have implemented strict defensive rules, which are summarized here.
