# The Basic Rules of Blackjack

Blackjack is one of the most popular casino card games in the world. Its appeal stems mainly from two factors: its simple rules, which are nearly identical everywhere; and its low house edge, which can be brought down to less than 1% if players use basic strategy. But even with these advantages, many players make mistakes that reduce their chances of winning. Some of these errors are minor, while others are major.

While some Blackjack players claim that there is no need to learn a strategy, this view ignores the fundamental role of math in the game. Using mathematical analysis and computer simulations, it has been shown that for every possible combination of the dealer’s cards and the player’s hand there is a particular playing decision that gives the highest probability of winning.

In a standard game of blackjack, each player and the dealer receive two cards. The value of each card is determined by its rank – number cards (2-10) are worth their numerical value, face cards (Jack, Queen, and King) are worth 10 each, and Aces can be worth either 1 or 11, depending on the situation. The player’s objective is to get a hand that is as close to 21 as possible without going bust.

The game rules allow for a variety of playing options, including surrender, pair splitting, doubling down, and hitting and standing. However, there are some basic blackjack rules that should always be followed.

When you play Blackjack, you should double down when you have a strong hand that can be improved by an additional card. This is most often done with aces and eights, but it can be done with any good hand that can be improved by an additional card.

You should also hit when your cards total 11 or less, and the dealer has a weak point that you can beat with a hit. It is also a good idea to hit when the dealer shows a face card and you have a soft hand.

In some situations, you may wish to surrender if you have a weak hand and the dealer has a strong one. This will cost you half of your original bet, but it is a good way to protect yourself from a bad result.

Some Blackjack players try to gain an advantage by chasing their losses, but this can be dangerous. You should never bet more money than you can afford to lose, and setting limits before you play is an important step in controlling your gambling. You can also set your own bankroll for Blackjack, which will help you to play responsibly and avoid the temptation of chasing your losses. You should also consider playing for free before betting real money, as this will give you a feel for the game and the rules. This will also help you develop a strategy before wagering real money. This way, you will have a better chance of maximizing your profits.
