Basic strategy is based on a blackjack player's point total and the dealer's visible card. A Blackjack player's ideal decision may depend on the composition of his hand, not just the information considered in the basic strategy. For example, a blackjack player should ordinarily stand when holding 12 against a dealer 4. However, in a single deck game, the player should hit if his 12 consists of a 10 and a 2; this is because the player wants to receive any card other than a 10 if hitting, and the 10 in the player's hand is one less card available to cause a bust for the player or the dealer.

Doubling down! Blackjack players are allowed to double down for any amount up to the original bet amount, so you could double down "for less" if you wanted. Online Blackjack tip: Just remember that you give up the ability to draw more than one additional card for being allowed to increase your bet. Internet Blackjack strategy: If the correct play is to double down, you should always double for the full amount if possible.

Splitting Aces! Splitting aces is a very strong move. Also, if you draw a ten-valued blackjack card on one of your split aces, the hand in not considered blackjack, but is instead treated as a normal 21. Always split aces.
