But in the short term, such as the cards are dealt from the deck, the remaining deck is no longer complete. By tracking the cards already played, it is possible to know when the remaining cards in the deck are advantageous for the players.Card counting creates two opportunities:
* The player can make larger bets when he had the advantage. For example, players can increase the initial bet if there is a lot of aces and tens are left in the deck, with the hope of hitting blackjack.
* Players can use information about the remaining cards to improve the basic strategy rules for specific hands played. For example, with many dozens of remaining in the deck, the player may double down in more situations since there is a better chance to make a strong hand.

Depending on the particular blackjack rules in a casino, basic strategy reduces the house advantage to less than 1%. Card-counting, if done correctly, can give a player advantage, typically ranging from 0 to 2% above the house. Card-counting mentally is legitimate and not considered cheating. However, most casinos have the right to ban players, with or without cause, and card-counting is often used as a justification for banning a player. Usually, the casino will inform the player that he was no longer welcome to play Blackjack at the casino and may be banned from the property. Players must be careful not to signal the fact that they were counting. The use of electronic or counting devices is usually illegal.
