The basic strategy was developed through intensive computer simulations which resulted in a complete combinatorial analysis. Through the computer calculated thousands of possible situations in each hand of blackjack, establishing statistically the best decision for the player. Before presenting the tables where are the results of the combinations and the respective games recommended for each situation, we'll explain the logic of the basic strategy of blackjack:

First, as a player, you should remember to follow three basic steps in each hand:

- Paying attention to the cards in your hand
- Meet the dealer's visible card
- Determine the probability that you and the dealer to bust.

Although the dealer should be governed only by the rules of the house has the advantage because after the players play, then even if both were to fail, which would lose the player. Taking them to specific numbers, the margin of the casino on the players in the game of blackjack is 5.5%. With this in mind, several mathematicians and great blackjack players have tried for a long time to reduce the house edge at blackjack and favor the player. The basic strategy is the result of one such effort.

The premise of which party's basic strategy is that the value of the cards that have a greater presence in the deck is 10: 16-card deck, 52 in total, worth 10 in the game of blackjack. Therefore, it is desirable for the player, assuming that the dealer's hole card is a 10, though often not. Thus, based on the visible card of the same, the player can calculate the total scores that could come to have the dealer.

If the dealer's visible card is a two, a three, four, five or six are likely to fail. For example if the dealer's up card was a 5 or 6, and his hole card a 10, his total (15 or 16) would be high enough to take another card to the final score of his hand more than 21 . In this case:

- If the score of your hand is between 12 and 17: be planted. Do not try to get to 21 because you might break and not worth being you could win anyway, given the high probability of bankruptcy that is the dealer.

- However there are some exceptions to this rule. When your hand is worth 12 points and the dealer's card is 2 or 3 you should take another card. And if you are 17 soft spots formed by an ace and a 6, you can take the chance to take another card since the total of your hand can be counted as 7 or 17.
