In poker, card counting is simply one component of a much broader strategy. It isn't used in isolation like it would be at the blackjack tables. How does it work? The general concept is identical to blackjack; we want to keep track of which cards remain in the deck, so we can estimate our chances of hitting big on the later streets. In counting cards, you add up card values to see what your odds are of getting a good hand. Cards 2-6 have a value of +1, cards 7-9 have a value of 0, and 10-ace have a value of -1.

Play NowWhat Is Card Counting?
Card counting is a technique in Blackjack that allows players to know when the advantage in the game shifts in their favour.
When that happens, they will increase their bets and win more than the house. When the advantage shifts in the dealer's favour, they will decrease their bets and lay low.
Easy, right?
By following a set of rules and adjusting their bets accordingly, the players (i.e. you) can win more over a longer period of time than when solely relying on luck and basic gameplay.
The idea of card counting is based on a scientifically proven principle that high-value cards are more beneficial for the player, whereas low-value cards are more beneficial for the dealer.
We'll teach you how to make this rule work in your favour.
How Does Card Counting Work?
Before talking more about card counting techniques, it's important to note that in Blackjack the cards are not shuffled after every round.
Instead, they are counted when the number of cards in a deck/decks decreases sufficiently.
After a deck is shuffled, there is an equal number of low and high cards in the deck.
As the game proceeds, the ratio of low and high cards changes. As we have already mentioned, high cards are beneficial for the player and low cards are beneficial for the dealer.
The dealer benefits from low cards because they are obligated to hit hands 12 to 16. If there are more low cards in the deck, there is a higher chance that the dealer will not bust when they hit.
To know when the deck is more saturated with high or low cards, the players assign values to the cards and then add them together.
- Cards 2-6 have a value of +1
- Cards 10-A have a value of -1
- Cards 7-9 have a value of 0 (because they benefit neither the dealer nor the players)
Card counters must pay attention to every card that enters the table and calculate the total sum of the cards.
If the sum of all cards is positive at the end of the round, the player will bet more in the next round. However, if the sum is negative, they will bet less.
The more cards have been played and the higher the positive count, the more money the player should bet in the next round. It's as simple as that!
Is Card Counting Legal?
Card counting seems illegal because you are basically trying to outsmart the Casino.
However, that's exactly what you're trying to do and nothing more. Therefore, no matter what anyone tells you (including Casinos), card counting is completely legal.
But (there's always a but), Casinos have the right to refuse to provide services to whomever they wish, whenever they wish, for whatever reason they deem valid.
Therefore, if Casino officials notice that you have decreased their edge by counting cards, they might refuse to allow you to play in their Casino the next time you come.
More often than not, you will be prohibited to play Blackjack while other games will still be available to you.
However, catching a card counter is not that easy, so it does not happen often. Therefore, you can start learning card counting techniques and not worry about getting caught
Pros and Cons of Card Counting
All that glitters is not gold is a popular proverb we should take into account when talking about the pros and cons of card counting.
Like many other things in life, card counting in Blackjack has both advantages and disadvantages. Let's start with the disadvantages first.
As we have mentioned above, even though card counting is not illegal and you cannot be prosecuted or sent to jail for it, it is still regarded as cheating.
Casinos monitor every table and every player at each table, which increases the player's stress levels when playing. Card counting will increase your chances of winning but it will also decrease the fun factor.
On the other hand, the main advantage of card counting is winning. Who does not like to win often? Blackjack has the highest RTP in Casinos, but the Casino's house edge can never be low enough, in our opinion.
If you do card counting right, you will definitely increase your bankroll.
Advanced Card Counting Techniques
The card counting technique we explained above is called the Hi-Lo technique. However, there are other, more advanced techniques, you should also practice once you have mastered the basic ones.
Omega 2
Omega 2 Blackjack card counting is also based on assigning cards a certain value, but the values are different:
- 2, 3 and 7 are counted as 1
- 4, 5 or 6 are counted as 2
- 9 is counted as -1
- 10 and all picture cards are -2
- 8 and Ace are valued 0
Contrary to the Hi-Lo method, a positive count means more low-value cards in the deck and a negative count means more high-value cards.
Wong Halves
Wong Halves is a balanced system invented by Stanford Wong. It is an advanced technique that uses full and half values:
- 3, 4 and 6 are counted as 1
- 2 and 7 are counted as 0.5
- 5 is counted as 1.5
- 8 is counted as 0
- 9 is counted as -0.5
- 10, Ace, and picture cards are counted as -1
To simplify this method, double the value of each card and avoid having to deal with decimal numbers.

Can you count cards in poker with the same strategy to get an edge over other players?
We answer that question by explaining the maths behind card counting in poker as well as how card counting can be used to count “outs” in Texas Hold’em.
What is Card Counting
To know if card counting in poker cash games is possible, we must look at the method used in blackjack as started by Edward O. Thorp.
Setting the card value
Assign a value to 52 cards in a deck as follows.
- +1 – 2♠3♠4♠5♠6♠
- 0 – 7♠8♠9♠
- -1 – 10♠J♠Q♠K♠A♠
Card values for other suits are also the same.
Counting the cards
Keep a score in your mind for every card dealt, including the ones that go to the dealer’s hand.
Here is an example of one random round in a blackjack game.
- Dealer has 9♠5♥4♦ = +2
- Player 1 has J♦J♥ = -2
- Player 2 has 4♥8♣K♦ = 0
- Player 3 has 3♦2♥7♣Q♠ = +1
Your total score for this round comes to a +1. Take note of this score as we move to the next round.
- Dealer has 4♥A♠5♣ = +1
- Player 1 has 8♥K♦ = -1
- Player 2 has 2♥7♣5♦5♥ = +2
- Player 3 has Q♦5♠8♣ = 0
Within the second-round, you should have a +2. With the tally from the first round, you should have +3.
Using the score
When the dealer used more than half of the cards in the shoe, use the running tally on all the dealt cards up to the current turn. You are tallying the house and your edge as the remaining cards are dealt for the last few rounds before the dealer uses a new deck. A positive score indicates the players have the edge while a negative or neutral score is a signal of the house having the edge.
If the score is +4 or more, you can take advantage of the edge by betting big. Players should double down on a bet if their hand is within this range such as 8♠2♥ or 4♣7♥.
Can Card Counting be used in Poker?
Blackjack card counting for poker games does not work since the method is to calculate a player’s odds against the house. However, in poker, you are not playing against the house but against other players instead. Card counting in poker to determine your edge over other players is still possible through two different methods.
Counting Out cards
Outs are the cards that have yet to be dealt from the deck. Players waiting on a straight or flush draw require a specific out to form or improve their hands. Knowing how many outs are possible for one round can help you make critical decisions such as calling someone’s over bet or placing a value bet on the last two streets.
Doing Texas Hold’em card counting for outs comes down to just deducting how many variations of the cards you need to form a hand. For a gutshot straight draw where you need one numbered card regardless of suit, four outs will form your straight. Open-ended straight draws are better hands because you can form a hand with two numbered cards on the top or bottom end, requiring 8 outs to make a straight. Since there are 13 cards with the same suit, flush draws have 9 outs.
Card counting method is not limited to just straight or flush draws. In the case of a Q♥6♥ hand and a 4♥Q♣2♥, you currently have a pair and are waiting on a flush draw, triple queens, quad queens, a queen and six two pair, and more. Your total outs should be 15 cards when you consider all the possible hands you can make.
Out card counting in poker provides an insight into your edge against other players. With more outs waiting for you on the turn or river, the higher your edge will be during the showdown. Folding or checking in situations where you only have four or fewer outs to make a solid hand is a reasonable strategy.
Calculating Hand equity
Hand equity poker card counting is a method to calculate your share of the pot based on the strength of your hand. Your hand equity drastically changes in each of a game’ street where your hand may start as trash and ends up as winning hand at the river or vice versa. Knowing your hand equity can help you determine your probability of winning against your opponents in one round.
You can already see your hand equity during the pre-flop through the strength of your hole cards. Pockets 10’s or higher tend to have better odds during this stage even if your outs are only two for quads or triples since you already have a hand at this point. Sequential cards with the same suit are the next best hands in terms of odds because of their probability to form open-ended straights or flush.
On the post-flop, you will get a clearer picture of your pot equity. With a J♦J♠ hand and an 8♥7♠Q♥ flop, for example, your odds here are slightly good if you are against one opponent. If you are going against two or more, your probability of winnings goes down since one of them could be carrying a queen that can topple your jack pairs or triples.
Take note that your opponents’ hand, apart from your outs, also determines your pot equity. You can get an educated guess of your opponent’s hand by observing their betting behavior. Tight players who prefer a high range tend to bet with an 8♥7♠Q♥ flop if they are holding a queen’s, giving them better hand equity. Aggressive ones are comfortable with betting on 8 or 7 pairs and waiting on a possible triple or full house draw.
Example of Poker Card Counting Calculations
Let us put into practice what we learned by doing some Omaha card counting. For the sake of this example, all players have their hands revealed to everyone.
Pre-flop
- Hero: 9♥Q♠5♠7♣ – 47%
- Villain 1: 3♦10♦8♠4♣ – 28%
- Villain 2: 10♥8♠5♣7♦ – 10%
You are currently holding a hand with the high odds of winning due to the queen card. Villain 1 has the second-best hand due to the 3♦10♦ hands that can form a flush. That player also has 3♦4♣ to form an open-ended straight.
Post-flop
- Flop: Q♣8♦3♣
- Hero: 9♥Q♠5♠7♣ – 42%
- Villain 1: 3♦10♦8♠4♣ – 47%
- Villain 2: 10♥8♠5♣7♦ – 2%
Odds have shifted to villain 1’s favor thanks to the 8♦3♣ cards that formed a two pair. Your odds have not drastically gone down like villain 2 thanks to the queen pair.
Turn
- Flop: Q♣8♦3♣6♣
- Hero: 9♥Q♠5♠7♣ – 30%
- Villain 1: 3♦10♦8♠4♣ – 52%
- Villain 2: 10♥8♠5♣7♦ – 8%
With this latest development, villain 1 is securing a win since there is only one more street for your out card of either a Q, 9, 5, 7 to create a hand that will beat others. Villain 2 manage to improve their odds by forming an open-ended straight draw.
River
- Flop: Q♣8♦3♣6♣5♦
- Hero: 9♥Q♠5♠7♣ – 100%
- Villain 1: 3♦10♦8♠4♣ – 0%
- Villain 2: 10♥8♠5♣7♦ – 0%
Fortunately, one of your outs appeared to form a queen high two-pair that beats villain 1’s hand.
Are There Card Counting Programs for Poker?
You can find several poker programs that can calculate hand equity based on players’ hand and community cards. One example is ProPokerTools’ Odds Oracle. You can recreate various scenarios for Texas Hold’em or Omaha and get the equity for each of them.
Odds Oracle recreation of various situations is much more than assigning specific cards to the two or more players and the community board. You can set the range of a player’s hand to have the top 5 to 15% card ranges during full-ring games. Going further, you can combine ranges or include rank spans on each hand.
Various Outcomes of each scenario are displayed through detailed charts. Odds Oracle even has interactive hand stats for the flop or turn where you can see the percentage of straight outs, back door flush, and various outcomes.
It is important to note that all card counting programs, including odds oracle, are intended for helping you calculate your odds of winning by yourself. Software for card counting in cash games that works with popular online sites is not available in the market. Once you get a handle on calculating your probability of winning, you can pull off card counting in WSOP live tournaments.
Is Card Counting in Poker Cheating?
A common misconception of card counting is its connection to cheaters who can beat the house with their amazing math skills. If this is true, why are casinos letting their patrons count cards in their blackjack tables? One of the reasons is the lack of ruling under local or federal laws that makes the practice illegal.
One solid reason why casinos allow you to count the cards is the small edge of 1% to 2% that counters can only get. Even without counting the cards, players still have the edge against the dealer since they are required to only stand with a hand of 17 or higher. Casinos want players to believe they have the edge against the house to keep playing and filling the establishment’s cages.
In the case of using card counting tips for poker, it is not considered cheating by any players. Cheating involves methods that give one person an unfair edge against other players. A classic example is the use of marked cards and special glasses that allow the wearer to know the cards everyone is holding. By seeing everyone’s hole cards, cheaters can fold when they see a strong hand or go all-in against a weak one.
Card counting is all about using the information available to you. People who have played several cash games can calculate their chances of forming a strong hand by determining the outs they need from their hole and community cards. Professional poker players take card counting further by getting a read on their opponent’s hand through their behavioral changes and betting habits.
Cheating in poker involves having more information than your opponents regarding the hands present during a game. However, card counting is a fair skill since counters have the same number of details to make an educated decision as everyone around the table has.
