Dealers bust card

Over the years lots of computer studies have been done on the game of blackjack using millions of hands analyzed to come up with a basic formula for how to play your hand in any given situation. This is known as Basic Strategy for Blackjack. The main principle that these decisions are based on is the dealer's up-card because, remember that the dealer has no say in whether or not to take a card – he or she must play by the rules that require him or her to draw a card until he or her has a total of 17 or more and stand on 17 or less. According to these computer calculations the dealer will bust more often when his up card is a 2,3,4,5 or 6 and he will complete more hands when his up card is a 7,8,9,10-value card or an ace. Take a look at the following chart that shows how each up card affects the dealer's chance of busting:

                                               Chance The Dealer's Up Card Will Bust

                                                                 2       35%

                                                                3       38%

                                                                 4       40%

                                                                 5       43%

                                                                6       42%

                                                                 7       26%

                                                                 8       24%

                                                                 9       23%

                                                                10     21%

                                                                 Ace   11%

As you can see, the dealer will bust most often when he has a 5 or 6 as an up card and will bust the least amount, approximately 11% of the time, when his up-card is an ace. This means it's to your advantage to stand more often when the dealer's up card is a 2 through 6 and hope that the dealer will draw cards that make him bust. It also means that when the dealer's up card is a 7 through ace he will complete more of his hands satisfactorily; therefore, in those situations you need to draw more cards until you have a total hand of 17 or more
