Blackjack and the importance in the size of its cover

Blackjack is very popular in the casino industry; it is fun and requires great skills on the part of the player to win. However, the game of blackjack goes beyond the goal of getting the precious number 21, since it is a casino game, although the prizes and winnings are merits of the interference and decisions that the players make during the game, the odds also they take part and have a considerable influence on the final result. This has allowed variants of the game to be developed, such as the cover.

It is very common to hear discussions in casinos about the dimensions of the blackjack deck and how much is better. Just as there are games of a deck, there are also others where two, three, four, five, six and more decks are used. It is said that the less they are used in the game, the better the chances of the player. But have you ever questioned about it? Or if it really is important to consider the dimensions of the cover for the game?

Assumption of  the blackjackthe-importance-in-the-size-of-its-cover

The truth is that when a player wants to start in blackjack, it must be deepened not only in the basic strategies and regulations, but in everything related to the game, which leads us to develop this article to deny or affirm some theories about the dimensions of The covers in a game of blackjack and if they really influence the odds of winning a player. The theory that is handled in the casino is that the smaller the deck, the more likely the player has to win. For this reason, you will explain below the details of this philosophy and if it is mathematically possible.

Small cover = much more blackjack

Every blackjack player knows or should know that of all the cards in the deck, 1/13 are Aces, this gives strength to the theory that the smaller the size of the deck, players can make more blackjack. But in theory, the proportions of the initial values of the cards would be equal to each other, regardless of the number of decks with which it is played. Actually, everything is that you can more easily eliminate a card from the game if there is a small shoe in blackjack.

Blackjack and the odds of getting a natural with only one deck

To begin, you have to consider an idea about the consecutive times with which a player gets a blackjack in games where there is only one deck. By multiplying the odds of taking an Ace by the odds of drawing a card with any value of 10 points, you would get the odds of getting a natural with a small shoe, which is really the goal. The deck contains fifty-two cards, of which sixteen cards are worth ten points consisting of: four tens, four jots, four kings and four queens, and the rest of the deck four are Aces.

Being Ace one of the most coveted cards during the game, the odds of drawing one is 4/52, which simplifying results in 1/13. After the ace, you will need a ten point card, but the odds of getting it out are 16/52. Here is an important note; the first probability is determined by 52 cards that make up the deck, while the second is based on 51 cards, the reason? If you get an ace, the deck no longer has 52 cards but 51, is that is why it is based on that figure and not on the previous one.

In this sense, the theory that says that if a deck is small, provides greater advantages to the player, begins to charge much more force. The player is advantaged by the possibility of getting a blackjack faster, while the house advantage is affected. In other words, if a player wants to know exactly the probability of getting the natural with a small shoe, what he has to do is double his result, since this can be achieved if he initially receives a card from an Ace or a 10.

In other words, 4.83% is the total odds a person has to win a blackjack from a single deck. This figure results from the odds of drawing an ace equal to 1/13 and in turn multiplied by the probability of obtaining a card of 10 points equivalent to 16/51, which must be multiplied by two.

A game with double deck and the odds of getting a blackjack

To reach a conclusion regarding the probabilities, you must start with the idea that a double deck has 104 cards instead of 52, and from there the possibilities of obtaining a blackjack start. To begin, the odds of a player getting an Ace with a double-deck shoe is 8/104, while the odds of getting a 10-point card from a double deck are 32/103. If you multiply these figures as in the previous approach and then duplicate them, the result yields 4.78%.

Comparing both scenarios of probabilities, you have that in a game of a single deck, the odds of obtaining a blackjack are 4.83% while the same odds to get a blackjack but with a double deck, is 4.78%. Obviously, the odds are reduced as more decks are added to the game even if the rules are not changed. The reduction by the casino in an additional deck is 0.05% taking into account that every time a blackjack is lost, the casino has a victory, and this is because the payments in a standard rule, is 3 to 2, and losing it, impacts the final balance of the casino.

Reasons why DoubleDowns is more efficient if you work with fewer decks

After proposing the scenarios of the dimensions of the decks based on the probabilities of obtaining a blackjack, it is a phenomenon that applies perfectly to the DoubleDowns probabilities and is the main reason why it is so successful. If a player, for example, doubles his first hand with 6 or 5, he is more likely to steal a face card with which he will form the desired 21 as long as he is using fewer decks.

But to these probabilities, you must add a third factor, and that is that distributors also enjoy benefits when there are changes in the lower counts. It is there where everything gets a little more complicated since the player is not the only one who is influenced by the odds of getting the natural one. In this sense, there is a reason why the game is not so affected and is that the players in general when they win the blackjack, the payment is 3 to 2, while the house would be winning only their money. Other factors, is that the dealer is prohibited from doubling unlike the players, this simple fact, represents a huge advantage over the dealer because it is an extra double win.
