Probability Blackjack Math

Unlike other casino games, blackjack is not entirely a game of luck. There is a lot of math and statistical knowledge involved in blackjack. If you want to become a winning player, you can increase your chances of winning if you study blackjack mathematics. Good blackjack players know that they must consider probability, statistics, and game theory when they sit down at the table to play. Entire books have been written detailing blackjack strategies and listing methods for calculating blackjack probabilities and blackjack odds.

The book Beat the Dealer by Edward O. Thorp, published in the 1960s, became a bestseller with its 'ten-count system' for keeping track of the cards in the deck. Card-counting became a widely accepted practice among blackjack aficionados to the extent that casinos changed blackjack rules in order to keep the house’s advantage intact.

See full list on gamblingsites.org. For example, the odds of a player receiving blackjack are 4.8%. That’s almost five natural blackjacks for every 100 hands played. Meanwhile, a player will be dealt cards totaling between 1 and 16 38.7% of the time. This means that you’ll have to make a decision on whether to stay or hit on approximately 39 of 100 hands dealt. The backbone of casino game mathematics is “probability.” Informally, we understand probability as a number that describes the chance that something will occur. It is usually given as a fraction or decimal with a value between 0 and 1, or as a percent with value between 0% and 100%. A probability of 0 means the event can never occur.

Advantage play in blackjack is defined as an attempt by players to win at the game honestly by employing memory, computations, and observation. These players, doing something actually very legal, are often undesirable in casinos because they end up winning more than the casino would like.

Card counting

Card counting is the practice of keeping track of the cards dealt in previous blackjack hands in order to calculate the possibility of specific cards being dealt in the current hand. Players good at this method can gain an advantage over the house. Card counting is much easier in one-deck games of blackjack, but can become quite difficult in multi-deck games, and in games with frequent reshuffles. While card counting mentally is completely legal, using external devices to enable this tracking is illegal. Players visibly seen as counting the cards at the blackjack tables are unwelcome guests in casinos and are frequently asked to leave the premises.

Card counters typically assign a point score to each rank of card that is dealt at the table, keeping a running score in their heads. As each card is exposed, the player adds the score of that card to the running total, which is considered the 'count'. After each reshuffle of the deck, the count starts again at 0.

The films “Rain Man” and “21” and some other blackjack movies included scenes of players counting cards, giving them an advantage over the casinos where they played blackjack.

Hi-Lo strategy

Hi-Lo strategy is a card counting system, and it is actually the easiest one to learn. Using the Hi-Lo card counting calculation system, all cards are assigned values of +1, 0 and -1 depending on their value in the game itself. Cards numbered 2–6 are called low cards and assigned a value of +1. Aces, tens, jacks, queens, and kings, the high cards, are assigned a value of -1. The remaining cards (7, 8, 9) are assigned a value of 0.

As each card is dealt at the blackjack table it is easy to add up the point values in your head. The greater that number is, the more high cards remaining in the deck to be dealt. This is a simple method of card counting that will make it easier to decide whether to hit, stand, split or double down on the cards you are dealt.

Shuffle tracking

Shuffle tracking is an advanced form of card counting. Instead of tracking the count of individual cards, the player keeps track of one or more subsections of cards as they are played. These sections are referred to as tracking zones. After the cards are played, and then shuffled, there are zones of cards in the upcoming deals which contain most of the cards in the original tracking zones. This method requires keen eye observation and memory skills

Probability in blackjack

Card counters and all avid blackjack players who rely on skill in order to achieve an advantage at the table employ some element of probability in their calculations as to what card will next be dealt. Players know the number of two-card combinations, the possibility of getting a blackjack, and the total number of possible outcomes in each hand. All of these skills are applied blackjack math.

When you employ a card counting technique, you can calculate the probability of specific cards being dealt to you, and, what the dealer’s face down card may be. Keeping track of the score will allow you to calculate the blackjack odds of being dealt a 3, or alternatively a face card. The more you keep track, the more you will be able to apply blackjack mathematics and know how to play.

Probability Blackjack Math Definition

Applying blackjack mathematics

Although card counting and the calculations it requires sound quite complicated, it is one of the methods players use to get an advantage at the table. Obviously blackjack math will be different when the game is played in a live casino as compared to game play online. Also, the number of decks in the blackjack will influence whether card counting is even a possibility.

Whatever blackjack strategy you employ, you must remember that more than anything else, blackjack is a game to be enjoyed, so make sure to have fun!
