# How to Win at Blackjack Using Odds and Probabilities

Blackjack is a popular casino game that requires a mix of skill and strategy to win. While many people believe that it is all about luck and that there are no strategies to help them, this is simply not true. In fact, the odds and probabilities are an important part of the game that players need to understand in order to improve their chances of winning.

#### Expected Value

EV, also known as expected value, is an important concept in most casino games and is used in blackjack to help players make decisions. It is a mathematical formula that combines the odds of a playerâ€™s hand and the cards being shown by the dealer.

The EV formula is important to know because it helps the player determine whether it is worth the risk of taking an additional bet. It is also helpful when deciding which moves to make in a particular hand.

#### Basic Strategy

Basic strategy is a series of rules that tell you what to do in a blackjack game in order to reduce the house edge and improve your odds of winning. It is not perfect, but it will usually save you from making bad decisions and letting the house take advantage of your mistakes.

#### Keep a Running Total

The best way to start keeping a running total is by practicing with a single deck of cards. Then, gradually increase the number of decks you use until you are able to quickly and quietly maintain a count. Once you have mastered this, you can use it to improve your chances of predicting the cards that will be dealt.

#### True Count

In addition to keeping a running total, you should also keep a true count, which is a simple calculation that allows you to see how many times a certain card has been dealt. This is especially useful if the game is being played with multiple decks and it can help you make more informed decisions on your bets.

#### Practice with a Small Bankroll

Before you play blackjack, it is essential to make sure that your bankroll is large enough to cover the amount of money that you plan to bet. If you are not careful, you could find yourself in a situation where you have run out of money and have to quit the game.

If you are a new player, it is important to start with a small bankroll and work your way up as you learn the game. This will allow you to become familiar with the different rules and strategies and give you an idea of how much you can afford to lose.

#### Surrendering a Hand

If your hand is very weak, it is a good idea to surrender the hand before seeing what the dealer gets. This will reduce your risk of losing and give you an opportunity to get back half of your original bet.

#### The EV Calculator

In blackjack, the EV calculator is an invaluable tool that can be used to calculate the odds of different situations and make more informed decisions. It is particularly useful when you are deciding whether to hit or stand. It also helps to determine when it is time to increase your bets through side bets.
