What is Card Counting?

Card counting is the practice of keeping track of the cards that have been dealt in a game of blackjack in order to make more informed decisions about when to hit, stand, or double down. The basic idea behind card counting is that if there are more high-value cards (10s and face cards) left in the deck, your chances of getting a strong hand increase. Conversely, if there are more low-value cards (2s, 3s, 4s, etc.), the dealer's chances of busting increase.

How to Count Cards

There are several different methods for counting cards, but the most commonly used method is the Hi-Lo system. In this system, each card is assigned a value: 2-6 are worth +1, 7-9 are worth 0, and 10s and face cards are worth -1. As each card is dealt, you add or subtract the appropriate value from a running count in your head.

For example, let's say the first three cards that are dealt are a 5, a 10, and a 6. You would add +1 for the 5, -1 for the 10, and +1 for the 6, which would bring your running count to +1. As more cards are dealt, you continue to update your running count accordingly.

Once you have a running count, you can use it to calculate the true count. The true count is the running count divided by the number of decks left in the shoe. For example, if you have a running count of +4 and there are 2 decks left in the shoe, the true count would be +2.

Using the Count to Make Decisions

Once you have the true count, you can use it to make more informed decisions about when to hit, stand, or double down. If the true count is positive, that means there are more high-value cards left in the deck, so you should be more aggressive and take more risks. If the true count is negative, that means there are more low-value cards left in the deck, so you should be more conservative and take fewer risks.

It's important to note that card counting is not illegal, but it is frowned upon by casinos. If you are caught counting cards, you may be asked to leave the casino or even banned from playing blackjack altogether. Therefore, it's important to be discreet and not draw attention to yourself.

Conclusion

Card counting is a skill that takes practice to master, but it can be a powerful tool for increasing your chances of winning at blackjack. By keeping track of the cards that have been dealt, you can make more informed decisions about when to hit, stand, or double down and gain an edge over the house. However, it's important to remember that card counting is not a guaranteed way to win at blackjack, and it's important to play responsibly and within your means.
