The Basics of Blackjack

Blackjack is a casino game in which the goal of each player is to beat the dealer by having a higher, unbusted hand. The cards are dealt in a circle to the players and the dealer, who is overseen by an often stern-looking casino employee called a pit boss. If the player surpasses 21 without busting, he wins; however, if both the player and the dealer have a total of 21, it is a push and neither party wins. The dealer’s hand is not exposed until the end of the round. Blackjack can seem complicated at first, especially when one encounters it in a live casino setting. But the rules are actually very simple. The key is to understand the role of mathematics, which can dramatically tilt the odds in the player’s favor. The game is played on a table with anywhere from two to eight decks of cards. The dealer is given two cards, with one face down. This card is referred to as the dealer’s hole card. During the course of the game, the dealer can check his hole card to see if he has a blackjack. Then he can pay off the player’s bet. A player can choose to “hit” (take another card) or “stand” (keep the same card). The dealer can also split a pair of matching cards into two separate hands, putting a second bet equal to the original in the betting box. A player can then play the two hands independently. An ace and any ten-value card is a blackjack, or a “natural,” and beats all other hands. It is also possible for a player to get a blackjack after splitting, provided that the first two cards are not the same. Some casinos offer insurance, which pays out 2 to 1 on a blackjack. This is an additional bet placed over the initial wager, and the dealer must ask the player for an insurance bet before dealing the first card. A player may decline to take insurance, or raise the amount of the bet to cover the cost of the insurance. There are several different blackjack variations, including games with no doubles or splitting of pairs, and those that don’t allow the use of wild cards. The game can also be played with a single deck of cards, or with a mix of both full and half decks. Some blackjack tables are marked to show the house edge, which is based on the number of decks being used and the rules of the particular game. A game with a high house edge is more likely to lose money to the player, while a game with a low house edge is more profitable. There are many strategies that can be used to reduce the house edge, including card counting and shuffle tracking. These techniques are legal and do not violate any gambling laws.
