How to count cards in blackjack?

Let’s see, can you count cards in blackjack online? The random number generator of any house is set up so that drawing cards from a shoe (a box containing cards) is a simple simulation. In fact, the system shuffles the decks after each hand.

Counting cards at Live casino

However, there are Live (live) casinos , where the dealer deals the cards in real time. Here it will be expedient to count the cards, and besides, no one will know about it. It will be more profitable to play at tables with a large number of participants – this way you can see more cards coming out of the game and count better.

So how do you count cards in a live casino? Possible application of “Empty card account”. To use it you need:

• Connect to a live casino blackjack table and start counting blackjack cards without placing real money bets.
• Only start betting when the deck is hot.
• You can start playing with a hot deck without spending money on the account.

Counting cards in the movie “Twenty One”:

Consider the movie Twenty-One, where Matt, a gifted student who is well versed in mathematics, finds himself in a group of fellow students who often visit Las Vegas.

In the movies, the players used the Plus-Minus scoring system, which will be discussed below. They even developed their own sign and word language to communicate the meaning of the deck’s current score to each other. Why did the blackjack card count give them such an edge over the casino?

The answer is simple: the more cards that have come out we know, the more accurately we can predict the probability of the remaining cards coming out. Or: the more pictures come out, the fewer of them are left in the deck. Therefore, the probability that the next card will be shallow (not a picture) depends on the ratio of the pictures that have already appeared and the total number of cards that have been issued (or remaining) (see the real score below).

How to count?

All “pictures” give 10 points each and for the counting system do not differ from each other, so that the player can successfully calculate the probability of cards of both large and small value. The basic blackjack strategy assumes the same probability of all cards coming out. But when we know that the probability of a particular group of cards coming out is higher than the rest, we adjust our strategy and get a positive mathematical expectation. This difference of a few percent allows the counters to beat the casino.

Is it possible to count cards when playing online:

Game progress

Which account is profitable for the player, and at which should you skip the game or lower the rate? What ratio of pictures and non-pictures in the deck are we trying to achieve? In short, we are interested in the situation when there are more large cards in the deck – aces and ten (pictures). Why?

• Firstly, for a combination of blackjack, the player receives a payout of one and a half bets. In other words, the more blackjacks we collect, the better. After all, if the dealer gets the ace and the picture, we lose one bet, and if we get it, we win one and a half.
• Second, the dealer is obliged to take cards until he has seventeen points. And if there are a lot of big cards in the deck, it is easier for us to predict the dealer’s brute-force when he put a five or six with the first card. The player, if he knows about the prevalence of pictures in the deck, can stop at twelve or sixteen points and protect himself from busting.
• Thirdly, by doubling the bet (Double) with a good first card, we increase the chances of a big card coming, getting 19-21 points and, therefore, winning a doubled bet.
• Now let’s move on to the card counting systems in blackjack and go back in time for a bit.

What are the ways of counting cards in blackjack:

Plus-minus system

Card counting was discovered by Edward Thorpe, back in 1962, he assigned values ​​to cards in the “absolute system”. But it was very difficult, each card had its own size: from -9 to +11, and therefore the counting process was incredibly difficult. Thorp’s system was in urgent need of simplification for use at gaming tables.

In 1963, a card counting system called Plus or Minus appeared, which was simpler and more understandable for the average person. Many meters still use this system. With minor modifications, it was used in the basic strategy .

In “Plus-Minus” all cards are divided into three groups, each of which is assigned its own meaning:

• +1 (for small cards: 2-6),
• 0 (for medium cards: 7-9)
• and -1 (for large cards: tens, pictures and aces).

According to the Plus-Minus system, the sum of the values ​​of all cards in a standard deck is zero. The same is true for a game with six or eight decks. During the game, we keep score by subtracting or adding values.

• Medium-ranked cards (sevens, eights, nines) are not counted.
• High cards (tens, pictures and aces) decrease the score by -1.
• Low cards (from two to six) add +1.

The Plus or Minus counting system works on one simple rule: if the score is positive, the probability of large cards coming out (and hence the mathematical expectation of the player’s winnings) increases, and if the score is negative, it decreases.

So how does the score affect the chance of winning in blackjack? When should you raise rates? To obtain information about the probabilities within a single game, you must refer to a real account. We can get the real score by dividing the value of the current score by the number of decks remaining in the game.

An example of using a real card counting:

• Let’s take an example of card counting in blackjack. Let’s say that one has already retired from a game with six decks, and the current score of the cards that have been issued is +12. Dividing this value by five (the number of decks remaining), we get the value of the real account: +2.4. How do I count the remaining decks in the game? Need to keep track of issued cards? Or ask the dealer to wait while we count the remaining cards? This is not necessary at all. The easiest way to estimate the number of decks remaining in the game is to evaluate the pile of played cards to the right of the dealer. We do not need the exact number – just an approximate value.
• And if you are sitting not far from the shoe, from where the dealer gets his cards, you can try to look directly into it. The main thing is not to make it too noticeable. These actions require serious training. You need to learn to at least roughly estimate the number of decks in a random pile of cards. You need to be able to accurately maintain a current account and quickly determine the real one.
• They first learn to do both in a relaxed atmosphere, and then try them in the noisy hall of the casino. You should not spare your time and energy to practice these skills: playing with the wrong score can lead to extremely unpleasant consequences. If you are not sure of your capabilities, do not bother with the score and play blackjack according to the usual basic gaming strategy.

Expected value:

Counting according to the Plus-minus system, you will receive the following values ​​of the mathematical expectation with the indicators of a real count:

With a negative value of the card count (-2 and below), you need to reduce the rates or skip part of the hands, continuing to count the cards of other players. If the score is positive (+2 and higher), the rates need to be increased. If the account deviates from zero, the basic strategy needs to be adjusted. The higher the real card count, the less often we take additional cards from 12 and the more often we take a sarrend (surrender at half time) on the dealer’s picture, as well as double the bet on the dealer’s five or six. It also becomes profitable to split large cards (Split).

Disadvantages of the system, plus or minus:

The main problem with the system is inaccuracy. In Thorpe’s system, for example, an ace is preferable to a ten, and a five is much worse than a two. The plus or minus system makes no distinction between these cards, strictly dividing the deck into three groups. But after all, the real score obtained as a result of the exit from the deck of fives will be much more useful than the score when the deuces exit. The same goes for tens and aces.

Regardless of the size of the real count, we believe that the probability of the appearance of a two and a five is the same, and the pictures will come out four times more often than an ace. This is where our knowledge of large and small maps ends. As for the rest of the cards (seven, eight, nine) – we paid absolutely no attention to them.

Despite its obvious imperfections, the Plus or Minus card counting system is one of the easiest to learn and most popular to use. The unreliability and inaccuracy of the data is more than compensated for by its ease of use and speed of learning.
