Blackjack is a casino card game where the objective is to beat the dealer. Players are dealt two cards and can either “hit” (receive additional cards) or “stand” (keep their current hand). The dealer also receives two cards, but only one is face up. If the player’s total is 21 on the first two cards, they win. Otherwise, the hand ties.
Players may also choose to split their cards into two separate hands if they are initially dealt pairs such as two aces, or two 10s. Splitting doubles the bet amount and players are allowed to receive an additional card on each hand. This increases the likelihood of a high value hand, but it can also increase the house edge.
Once the players have finished playing their hands, the dealer will reveal her hole card (as shown in the picture above). If she has a blackjack, the player’s original bets lose unless they have a blackjack themselves. If she does not have a blackjack, the player’s side bets push (get their original bet back) and the round ends. The dealer then collects the cards, shuffles them and begins a new round.
While some people may think that the dealer’s hole card is not important, it can make a big difference in a game. For example, many players will hit a hand value of 16 when the dealer has a 10 showing, but this is almost always a losing move. The dealer will bust nearly 80 percent of the time with a 10, and it is highly unlikely that the player will hit a blackjack when the dealer has a 10 up.
Before the players begin playing, the dealer will usually ask for insurance bets. These bets are placed on a special bar above the player’s cards. The dealer will then check her hole card using a viewing window in the table, and if there is a ten underneath, she has a blackjack, and the players who made insurance bets will receive 2 to 1 on their wagers.
There are a number of different strategies for playing blackjack, and some players use a combination of these to maximize their chances of winning. The most basic strategy is to stand whenever your hand value is less than 17 and to hit when your hand value is 18 or higher, and the dealer has a face-up card of 9 or lower. It is also important to double down on 11 against a dealer’s 10, and never split 10s or aces. In addition, some players use a system of counting cards to optimize their decisions. This requires a great deal of practice to master, but it can dramatically improve your odds of winning. However, it is important to remember that even the best players can lose to a lucky dealer. Therefore, you should only play at reputable casinos.
