Basic Blackjack Strategy

The exciting thing about card games in general is that the results
are somewhat more predictable than games involving dice and wheels.
Sixteen cards, a whopping 30 percent of the deck, are valued at
ten when playing blackjack. That climbs up to 38 percent when you
include nines and 46 percent when you include eights. Consider the
dealer's hole card. There's a really good chance it's an eight,
nine, or ten. Does that change your impression of a six upcard?
There is a nearly one in two chance that the hand is a fourteen,
fifteen, or sixteen. And consider what will come out of the shoe
when the dealer hits.
Meanwhile, you have a hard thirteen. What's coming out of the shoe
for you? Hitting a hard thirteen against a dealers six doesn't seem
so appealing anymore. With a six upcard, the dealer will bust about
42 percent of the time. Why screw that up?
Mathematicians have worked out the various probabilities. The result
is a basic strategy for playing blackjack that in most cases reduces
the overall house edge to less than one percent. Favorable rules
push the edge past zero into positive territory. The "Basic
Blackjack Strategy" table below contains a version of the strategy
that is optimized for multiple deck games when the dealer stands
on soft seventeen and when doubles are not allowed after splits.
Variations of the strategy for hitting soft seventeen and doubling
after splits are minor and we'll cover them in a later section.
Basic strategy is easy to use. Just find your card combination
on the left and the dealer’s upcard at the top. Follow the
upcard column down and your card combination across the row until
the two intersect. That's how you should play the hand. If some
of the strategy choices seem odd, then you'll find our "Dealer
Bust Probabilities" below useful. It shows the probable outcome
of a dealer's hand based in the upcard.
At first glance, basic blackjack strategy may seem complicated,
but it's simple. About one-third of the hands should always be played
the same way, regardless of what the dealer is showing. The rest
of the hands, with a few exceptions, should be played one of two
ways. This is determined by the dealer's up card.

Note: Hard totals are total hand values without
an ace in your hand a soft total is when you have an ace in your
hand. The strategy changes depending on which you have. Table's
