Blackjack is a card game popular in casinos.

this game would come from the French card game twenty-one called Chemin de Fer.

Rules:
The party opposes all players against the bank. The goal is to approach or to 21. Once a player exceeds 21 they say he jumped and he loses his initial wager. The card values are determined as below:

* February-October → nominal value of the card
* 10 points each figure →
* Ace → 1 or 11 (optional)

Blackjack is an ace and made a figure, if an Ace with a 10, or 21 with 3 or more cards, it counts for a 21, blackjack is above 21.

Early in the game, the dealer deals one card face up to each player draws a card and also face up to him. He then draws a second card for each face and draws a second card face down to him.

Then he asks the first player from the table (player to his left) he wants a card or not. If the player wants a card, he must announce by saying "Card! . The player may request as many cards as they wish. If after the draw of a card, he passed 21, he loses his bet and the dealer the next player. If he decides to stop, saying "Served", the dealer also passes to the next player.

The dealer repeats this process until all players are served.

Then he played for him by a simple rule and codified: it reveals his card that was previously hidden face, then pulled a card as he has less than 17, otherwise it stops. If more than 21 all remaining players win and if it is between 17 and 21 tie the player of the bank according to the height of the hand. In case of tie, the player keeps his bet but does not pocket any more.

After the initial distribution of cards, the player can use other insurance possibilities of the game: If the dealer's upcard is an Ace, a player has the option to insure against his blackjack. Thus, if the dealer has blackjack, the player keeps his bet and his Insurance. However, if the latter did not blackjack, it also cash insurance. For sure, we must make a bet equal to half of its stake.

Pairs: When a player gets two cards of same value, it is possible, by depositing the same bet as the first to have two separate games. Both games and the two bets are independent, however, a player with more points than the banker with his two games and without having put out so pick up twice that he could win without a pair. If the tie with a pair of aces, ten or figure gives rise to a blackjack, the payment of the wager is doubled.

Material:
Initially, there were parts of blackjack is played with one deck of fifty-two cards. Nevertheless, the appearance of card counters, that is to say people who can remember the order of cards, the game never being beaten or cut, has prompted casinos to raise the level by using six sets fifty-two cards.

Counting cards:
The basic strategy provides the player the optimal play for any blackjack situation based on millions of hands played in the long term. However, in the short term, while the cards are played the shoe, the shoe is more complete. By following the cards that have already been played, it is possible to know when the remaining cards in the deck are advantageous for the player.

Card counting allows two kinds of opportunities:

* The player can bet more when the cards remaining in the deck are to his advantage.
* The player can use information on the remaining cards to improve the basic strategy for specific hands.

There are several card counting systems, which do not require the player to remember every card played. In fact, a point system is established for each card and the player follows the scoring when the cards are dealt by the dealer.

Under the rules applied by the casino blackjack, basic strategy reduces the house edge to less than one percent. Counting cards gives the player an advantage of 0.5 to 1.5% on the house.

Basic Strategy:
Blackjack, unlike other games, also depends on the player's choice, which can reduce the casino advantage, playing with a "basic strategy" ("basic strategy" in English). This strategy determines when to hit and when to stop. It also determines when it is best to double down or split two equal cards. This strategy is based on a comparison between cards of the player and the dealer's visible card. However, there are variations in the basic strategies, depending on the rules used by the home and the number of decks used.
