How to Beat the House Edge in Blackjack

Blackjack is a card game played by two or more players and against a dealer. The game has a large following in the gambling industry and is a favorite among many casino visitors. In order to beat the game, it is important to use math skills and learn basic strategy. The best way to increase your chances of winning is to keep your bet size consistent and to make decisions based on the odds. Using the proper strategy will allow you to win more hands than lose and can eventually lead you to profitability.

When to hit

In general, you should always hit when your cards add up to 11 or less. It is very difficult to bust with this hand, and it gives you a good chance of beating the dealer’s up-card. However, if your cards total 17 or higher, it is more beneficial to stand. This is because the dealer has a very low probability of hitting a seven or higher and will almost certainly bust when he or she does.

When to stay

The decision when to stand in a blackjack hand is one of the most important and is based on the dealer’s up-card. If you have a score of 16 or 17, it is often better to stand than to try to improve your hand. It is unlikely that you will be able to improve your hand into something higher than an 18 without going over 21. An 18 is a strong hand value, and the dealer will have to have an extremely lucky draw in order to beat it.

When to double down

Doubling down in blackjack is a betting option available to players once they have received their initial two cards. This action entails requesting another card while adding an additional wager equal to the player’s initial stake. The player’s turn then ends after this third card is dealt. Doubling down is usually only offered on certain hands, such as a pair of eights or aces.

When to split pairs

Splitting pairs in blackjack is a common strategy that can result in significant gains for the player. This is because the cards in a pair have different values and can be ranked differently according to their rank. It is also important to note that splitting 8’s and aces will, if the dealer has a face card, reduce the house edge considerably.

When to buy insurance

Insurance is an optional side bet that a player can make when the dealer shows an ace. It is a bet of up to half the original wager and pays out at 2 to 1 if the dealer has blackjack. It is generally not wise to buy insurance, as the player’s expected return is lower than that of playing blackjack alone.
