## Blackjack Odds

Blackjack is a casino game that more than anything else is about odds. Basically, it’s about the risk of you cracking compared to the chance that you’ll get a better hand than the dealer. The former the risk of cracking if you take out a new card is easy to calculate.

As long as your hand is worth 11 or less, there is no risk that you will get over 21 if you take a new card, and you will then either double, take a new blackjack or, in some cases, split. Under no circumstances should you stay if you have 11 or lower, as you will always get a better hand if you draw another card.

The risk of getting fat starts with 31% if your cards are worth a total of 12, and then increases to 100% if you have 21. But staying with 12 on the hand is rarely a good idea, as the risk is high that the dealer will get a better hand. We call this type of calculation a Blackjack system .

However, there are exceptions if the dealer’s open card shows 4, 5 or 6, the odds are best that you will win if you stay otherwise take another card. If you are 13-13 then you should stay if the dealer has 6 or lower, otherwise take a new card. There is a special rule here if the casino allows you to give yourself the opportunity to give end the hand against giving up half your bet without a fight then you should do so if you have 15 and the dealer 10, or if you have 16 and the house, 9, 10 or 11. If you are 17-20, you should always stay.
