Card counting is a technique used to keep track of the cards that have been dealt and estimate the probability of getting a favorable hand. There are different methods of card counting, but the basic principle is the same: assigning a value to each card that has been dealt, and adding or subtracting that value from a running count. The running count gives an estimate of the remaining cards in the deck, and the player can adjust their bets accordingly.
Hi-Lo Counting System
The most popular card counting method is the Hi-Lo system, which assigns a value of +1 to cards 2 to 6, a value of 0 to cards 7 to 9, and a value of -1 to cards 10, J, Q, K, and A. The player keeps a running count of the cards that have been dealt, and divides the running count by the number of decks remaining to get the true count. The true count is a more accurate estimate of the remaining cards, and the player can adjust their bets accordingly.
