Blackjack is one of the most popular casino games. The game is played against the dealer and the objective is to have a hand value that is closer to 21 than the dealer’s without going over. There are a number of strategies that can be used to improve the player’s chances of winning. One method is called card counting which allows the player to increase their bet size in favorable situations and make decisions based on the information they have gathered as the game progresses. Another strategy is to play basic strategy which reduces the house advantage to less than 1% if the rules are followed.

When a player’s first two cards are an ace and a ten-card (or a picture card or a 10), this is called a blackjack, or “natural” and the player wins automatically 3:2 as long as the dealer does not also have a natural. If a player has a natural and the dealer does not, the dealer will offer the players even money, which is equal to their original bet. The dealer will then take any insurance wagers.

After each player has hit or stood, the dealer takes their turn. They can re-hit or stand depending on the cards they have in their hand. Once the dealer has a valid hand, all the players’ hands are compared to theirs to determine who wins. If a player’s hand is higher than the dealer’s, the player wins and their original bet is returned to them. If a player and dealer have the same hand, this is called a push or tie and neither player receives their original bet back.

The game of blackjack can be influenced by various factors, such as the number of decks in use and the rules of the particular casino. However, the overall house advantage is a fixed percentage which will always play itself out over time. This advantage can be reduced to less than a percent using basic strategy, which is a set of playing guidelines that are based on probability calculations and the knowledge of how many cards have been dealt.

Several legal methods can be used to gain an edge in blackjack, including a technique called “shuffle tracking.” This involves keeping track of the number of cards that have been removed from the deck and estimating how many remain. It can be combined with basic strategy to give the player an edge over the dealer, but is still not foolproof.

In addition to being knowledgeable about the game of blackjack, a certified blackjack dealer must be able to handle complaints and disputes calmly and professionally. They must also be able to identify any type of foul play or cheating that may occur during gameplay. These skills can help a dealer to earn more money and improve their reputation as a reliable and responsible casino employee. Having good customer service is important because it shows that the dealer cares about the players’ experiences at the casino.
