black jack strategy

casino

The most important thing to know about black jack is the basic strategy. This strategy is simply the best way to play every possible situation, without any knowledge of the distribution of the rest of the cards in the deck. Following is the basic strategy for four of more decks when the dealer stands on soft 17. Links are also provided to more basic strategy charts for other rules. However the most common game is the multiple deck game (4 or more decks) where the dealer stands on soft 17. If you only memorize one table I would suggest the one below. It can be played effectively under any rules.

To use the basic strategy look up your hand along the left vertical edge and the dealer’s up card along the top. In both cases an A stands for ace. From top to bottom are the hard totals, soft totals, and splittable hands. Rule variations can have an effect on some borderline situations. The most flexible rules are the number of decks, whether the dealer hits or stands on a soft 17, and whether doubling is allowed after splitting.

Basic black jack Strategy

Key to table:

H       Hit
S       Stand
D       Double if allowed, otherwise hit
Ds     Double if allowed, otherwise stand
P       Split
H/P    Split if allowed to double after a split, otherwise hit
H/R    Surrender if allowed, otherwise hit

Some obvious situations have been left out to keep the chart as small as possible. I have more basic strategy charts for other numbers of decks, as well as European black jack.

  • 1 deck
  • 2 decks
  • 4 or more decks
  • European black jack

The best way, I have found, to memorize the basic strategy is notice patterns and to try to understand why you should play every situation as the chart says. Then make flash cards and go over and over them until you know it cold. Do not deal out cards to yourself because the soft totals and the pairs will not occur often enough to test your knowledge.

Many people do not believe in the basic strategy because they once took the advice of someone who knew it and then lost the hand. Let me make something perfectly clear, you will not win every hand with the basic strategy! In fact you won’t even win half your hands. However I can personally testify that while you will have short term ups and downs over the long run you will roughly break even using it.

Single Deck:

To use the basic strategy look up your hand along the left vertical edge and the dealer’s up card along the top. In both cases an A stands for ace. From top to bottom are the hard totals, soft totals, and splittable hands. There are two charts depending on whether the dealer hits or stands on soft 17.

European black jack:

The following basic strategy table is appropriate for European black jack, at least the variation I saw played in Berlin and Hamburg. The specific rules are as follows:

Six decks (this chart is also accurate for 4 or 8 decks)
Dealer stands on soft 17
Player may only double on hard totals of 9-11
Player may double after a split
No-peek (player loses total bet, including after doubling or splitting, if dealer has black jack)
The house edge under this rules is 0.62%.
