Blackjack Strategy

The Blackjack strategy is the optimal way to play your hand when not counting cards. This blackjack strategy is derived from a computer simulation in which the computer deals out millions of hands, plays them, and then analyzes the results. The blackjack strategy is not based on hunches. Basic blackjack strategy is the mathematically correct way to play your hand against every dealer's hand.

Blackjack Tip

Play only at tables offering the most beneficial conditions.

Blackjack strategy enables you to improve your edge. The casino's initial edge in the game of Blackjack is approximately 5.75%, which includes the 3 to 2 payoff on player Blackjacks. By employing the correct blackjack strategy, it is actually possible to reduce the casino's edge to about 0.5%, as per the following:

Initial casino's edge - 5.75%
Correct hitting and standing - 3.25%
Correct doubling - 1.5%
Correct pair splitting - 0.5%
Casino's edge with basic blackjack strategy - 0.5%

It is certainly possible to lower the casino's edge to less than 0.5% by playing in games that have very favorable rules. A blackjack strategy player has in fact a slight edge against the casino in these games.

Blackjack Tip

Hit until you have at least 17 against the dealer's 10.

Blackjack Strategy

• Watch out for a weak dealer hand. Blackjack strategy states that some hands, like 5 or 6, are extremely weak, since the odds for the dealer to bust are high. Blackjack strategy when the dealer’s hand is weak recommends that you stay with your cards whether they are strong or not.
• Always double down on 10 or 11 cards when the dealer’s is 9 or less and 10 or less. Blackjack strategy rules state that you have a strong hand, so take advantage of it.
• Always Split 8's and Aces.
• Never split 4's, 5's or 10's.
• Never take insurance, unless you're counting cards.
• Always follow strict basic blackjack strategy rules.
• Surrender when necessary.

Blackjack strategy depends on the number of decks of cards used in the game. Thus, the blackjack strategy for a single deck game is slightly different than a six-deck game.
