Card counting is a casino card game strategy used primarily in the blackjack family of casino games to determine whether the next hand is likely to give a probable advantage to the player or to the dealer. Card counters are a class of advantage players , who attempt to decrease the inherent casino house edge by keeping a running tally of all high and low valued cards seen by the player.
Card counting allows players to bet more with less risk when the count gives an advantage as well as minimize losses during an unfavorable count. Card counting also provides the ability to alter playing decisions based on the composition of remaining cards. Card counting, also referred to as card reading , often refers to obtaining a sufficient count on the number, distribution and high-card location of cards in trick-taking games such as contract bridge or spades to optimize the winning of tricks.
The most common variations of card counting in blackjack are based on statistical evidence that high cards especially aces and 10s benefit the player more than the dealer, while the low cards, 3s, 4s, 6s, and especially 5s help the dealer while hurting the player. Higher concentration of high cards benefit the player in the following ways. Thus a dealer holding will bust every time if the next card drawn is a 10, making this card essential to track when card counting. Contrary to the popular myth, card counters do not need unusual mental abilities to count cards, because they are not tracking and memorizing specific cards.
Instead, card counters assign a point score to each card they see that estimates the value of that card, and then they track the sum of these values — a process called keeping a "running count. Basic card counting assigns a positive, negative, or zero value to each card value available. When a card of that value is dealt, the count is adjusted by that card's counting value.

When it comes to the number of decks in a blackjack game, the fewer the better. I often get this question by email, where players will note that the proportion of each rank of card is the same whether the casino uses a single deck or shuffles six decks together.
Regardless of how many decks are in play, we start out with one thirteenth of the cards being Aces…. Despite the initial card proportions being equal, in games with fewer decks you will be dealt more blackjacks. You will also be more successful in your double downs. How can that be, when all the ranks are equally represented no matter how many decks are used?
It is because removing cards has more impact in a game with fewer decks. To get the probability of drawing a blackjack from a single deck, we multiply the chance of drawing an Ace by the chance of drawing a ten-value card. In a single deck of 52 cards there are 4 Aces and 16 ten-valued cards 4 each of Ten, Jack, Queen, and King. Note that the second line reduces the number of cards in the divisor to 51, to account for the removed Ace.
We also need to double the result since we could draw either Ace,Ten or Ten,Ace. Our final result is: Same idea with two decks, with different numbers. More decks means slightly fewer blackjacks. In six decks, the probability drops further yet to 4. The same effect impacts double downs. If you double your initial hand of 6,5 for a total of 11, then you are slightly more likely to draw a face card to make 21 if the game uses fewer decks.
Astute readers may notice that the dealer gets the benefit of these changes as well. But note that a player wins 3: And for hands like the double down example, the player wins twice the initial bet.

Beyond the basic strategy of when to hit and when to stand, individual players can use card counting, shuffle tracking or hole carding to improve their odds. Since the early s a large number of card counting schemes have been published, and casinos have adjusted the rules of play in an attempt to counter the most popular methods.
The idea behind all card counting is that, because a low card is usually bad and a high card usually good, and as cards already seen since the last shuffle cannot be at the top of the deck and thus drawn, the counter can determine the high and low cards that have already been played. He or she thus knows the probability of getting a high card 10,J,Q,K,A as compared to a low card 2,3,4,5,6.
