Card counting is a technique used in blackjack to gain an advantage over the house. By keeping track of the cards that have been played, a player can estimate the probability of certain cards being dealt in the future. This information can be used to make better betting and playing decisions, which can lead to increased winnings.
Card counting has been around for centuries, and it has been used by some of the most successful blackjack players in history. However, it is important to note that card counting is not a guaranteed way to win money. It requires skill, practice, and discipline. Additionally, many casinos frown upon card counting and may take steps to prevent players from using it.
