Blackjack is a casino table game that involves playing against the dealer. The player’s goal is to have a higher hand value than the dealer, without going over 21. The game is played on a semicircular table that can accommodate varying numbers of players, known as “spots”. The dealer stands behind the table and chip rack.
Blackjack strategy is based on probability and mathematics, rather than chance. A computer analysis of all possible combinations of the player’s cards and the dealer’s card results in a single play (hit, stand, split or double) with the highest probability of winning. A player who knows this basic strategy can dramatically reduce the house edge and increase their chances of winning.
Each blackjack round starts with two cards being dealt to each player. If a player has an ace and a ten-value card, they have a blackjack (also called a natural). This is an automatic win as long as the dealer does not also have a blackjack. The dealer must pay the player one and a half times their bet if they have a blackjack, and in the event of a tie, all bets are returned with no adjustment.
Some casinos have reduced the payout of blackjacks from 3:2 to 6:5. This changes the strategy of the game and makes it less profitable for the players. However, this is not the case in every casino and it’s important to read the rules before you sit down.
If the player’s initial two cards have a value of 11 or higher, they can choose to split their cards and receive an additional card for each new hand. The player must then decide whether to keep the split hands or discard them. The player can also double their initial bet on a given hand, if they believe that the additional card will help them reach a better total than their original two cards.
Once the player has determined their action, they must wait for the dealer to reveal her hole card. If she has a ten underneath, she has a blackjack and wins the round. If she does not have a blackjack, the players who purchased insurance will be paid 2 to 1 on their bets.
Occasionally, the dealer will have a blackjack and lose to the player, but this happens very rarely. The dealer’s best chance to beat the player is to draw a hand value that goes over 21, which is difficult to do. The dealer’s other option is to stand with an ace and a ten-value or face card, which is very unlikely. If the dealer does not have a blackjack, she will usually return all bets with no adjustment. This is a called a push. The player should only bet more money on the next hand if they are sure that they can beat the dealer’s. Otherwise, they should quit while ahead and play another table. This is especially important on hot tables.
