Count the s cards in Blackjack: this is how it works

It is no secret that Blackjack isone of the casino games with the lowest house edge. Sin embargo, a pesar de utilizar la estrategia básica optima en cada turno, resulta sumamente dificil vencer a la banca a largo plazo.

Because of the large decision margin that a hand presents, some betting geniuses developed amathematical system to count the cards and establish clear betting patterns and odds of appearance that will grant winnings to the participants in 100% of the cases. On this page we will explain the technique used, step by step, so that you become experts on the subject.

To understand the logic behind the strategy

The standard strategy is essential!Resumen de estrategias para contar cartasTake a look at the tables with strategies here.

By counting the cards, it is possible to recognize the remaining ones in the deck and thus have an overview of favorable situations that generate profit or, conversely, disadvantage leading to losses on pending hands. By having access to this knowledge and a little patience,any participant can place high bets, knowing that he will win the next game and, with it, recover the amounts lost until the moment.

The systematic counting of cards directly influences the bets placed at the beginning of a turn, although for its effective use, it should be used in parallel withthe basic betting strategies, since each game must be used optimally, in order to see long-term benefits.

Recognize when atable is “hot” , that is, ready to be approached, is of great importance, since this defines the moment in which the bets will increase, as well as the profits. How do you know if you have reached this point?

When in the set of decks, the majority of cards contained areAces, 10es and images instead of small numbers|| |231, la probabilidad de obtener naipes altos y una puntuación elevada es incrementada considerablemente. Para obtener esta calculación, es necesario contar cada carta descubierta individualmente, incluidas las repartidas entre los participantes y el Dealer.

In this procedure the real value of them is not counted, but the“relationship” between large and small figures. After a while, there will be few cards in the deck and if most of them are high denominations, then it will be the ideal time to attack the house.

Value counting system

El método más sencillo (en efecto, existe más de uno… y al final de este artículo sabréis todo acerca de ello) es the one known as Hi-Lo: a cards 2 through 6 are given a value of +1; while Aces, 10s, Js, Qs and Ks are assigned a -1. The 7, 8 and 9 do not belong to any of these categories and therefore remain neutral with an overall value of 0.

As soon as the game starts with aset of decks “fresh and virgin”, the count starts at zero. With each card drawn from the deck, the above values ​​are added or subtracted.

The index moves from the positive to the negative fieldthroughout the game, depending on the cards that are appear. When the deck is at about 2/3 of use, attention must be paid to the immediate development of the following hands, since the possibility of preparing ground for the attack is approaching, but only if the balance is in positive numbers. To determine if the time is ideal, the “real calculation” is used.

Set Bet Controls

A positive current count (+5, for example) is not great relevance at the beginning of the game, when there are still many cards in the deck.The situation changes once the game is advanced -near the last phase of the game), since a positive value (however small it may be), greatly influences the odds of winning.

Hereshould be considered in parallel with the value of the cards, the so-called “real calculation” (or “true count” in English) , by which the relationship between the current value and the permanent cards in the deck is estimated. Based on this, it is possible to limit the total bet to move in the following turns.

The easiest way to make the calculation is to divide the current value by the number of pending decks, and then multiply the result by the total number of decks.

The same principle remains with the number of pending cards. However, these must be calculated together with their current value, so the operation can be more complicated.

To avoid losing cashwhen playing Blackjack for real money, before becoming completely familiar with the method, we recommendto set only the minimum limits allowed by the table at the beginning. As you gain experience, you can raise the stakes and, when the time comes, directly apply the real calculation information to bet large amounts.

If thereal calculation is +1, 0 and even in a negative range, it will be necessary to remain with the minimum amount of bets . In the end, it may happen that the account does not grow to favorable levels, even once you have entered the last third of the deck.

In this case,you will have to wait until it runs out and a new deck is shuffled. We referred to this point at the beginning when we mentioned that patience – and not just mathematical ability – is a requirement to get the most out of this game.

The optimal strategy for counting cards in Blackjack|| |310

Seguramente, más de un usuario habrá reconocido el proceso de conteo en documentales sobre personajes conocidos, como the famous Edward O. Thorp, or more recently, the film based on the group of students/professors at MIT (Massachusetts Institute of Technology) “Blackjack 21”, where the protagonists manage to accumulate large profits by successfully using their skills with the counting system.

However, many other strategies have tried to complement the tools and even solve the present deficiencies, such as thelarge range in the evaluation of the cards. What does this mean? That a 2 is not equal to 6, or an As has two different values. These characteristics need to be considered to further increase the chances of winning.

In response to this "problem" is that characters like Lawrence Revere, Ken Uston and Stanford Wong (to mention only the most outstanding) created different methods of greater complexity and, therefore, much more difficult to apply. Eventhere are some variants that do not consider the actual calculation at all and work only with the individual card count.

The table below will show you an overview of the differences present in the different systems, without dwelling too much on the details.

Conditions for the system not to work

In the different types of payment it is recognizablethe difficulty to generate profits with each card count , since the strategies must be changed and adapted to the rules and individual situations that alter the development of the variables.

There are also somevariants of Blackjack in which it is impossible keep track, because after each game, a new deck is shuffled and dealt, thereby returning the count to the original “0”.

Fortunatelyesto es poco común en los casinos tradicionales, due to the high cost of personnel or machines to carry out this task. In contrast, online it takes only a fraction of a second for a full set of decks to be shuffled and returned to the table.

But there is one exception to this constant:Casinos with live blackjack, because real cards and dealers are used here, but with online transmission to the home of each participant.
