Once all cards have been dealt, the Dealer will look to the first
Player to his left and move to each subsequent Player for a decision
to take an additional card (hit) or accept the hand (stand). We will
assume that you're sitting at a table where the cards have been dealt
face up. If a Player decides to hit, he will scratch his finger on
the tabletop and the Dealer will dispense another card. The Player
may take as many additional cards as he requests until he either feels
like he may beat the Dealer's hand or he goes over 21. If the hand
exceeds 21, the Player automatically loses (busts). When the Player
decides to stand, he simply waves his hand over the cards.
The Dealer will play his hand once all the Players have completed their hands. First the Dealer reveals the card that is face down. If his initial two-card total was 16 or less, he must take additional cards until his total is 17 or more. If the Dealer's two-card hand totals 17 to 21, he must stand. The Dealer will also bust if his additional cards cause his card total to exceed 21.
If you lose your hand against the Dealer, you lose your wager. If you win the hand against the Dealer, you are paid even money. It is possible to tie the Dealer. In that case, you neither win nor lose, but have a push. If you receive a natural Blackjack, a two-card hand consisting of an Ace and a 10, you automatically win one and a half times your original wager. However, if the Dealer is also dealt a natural Blackjack, it is a push.
Double Down - After your two cards are revealed, you have the chance to double your wager by placing the same amount next to your original bet. The rule for doubling down is that you must take one card and one card only. Many people suggest, and some casinos only allow, doubling down when your two-card hand equals 10 or 11, since the odds of receiving another 10 are greater than any other valued card.
Splitting a Pair - If your two-card hand is an identical pair (two 7s, for example), you are given the opportunity to match your original wager, split the two cards and then play as two separate hands. You would play each hand individually by hitting or standing.
Insurance - Although Dealers and casinos encourage Insurance bets, we've been told over and over that it's not a financially rewarding bet. If the Dealer's face-up card is an Ace and his second card is still face down, you may place an Insurance bet, which is half of your original wager. If the Dealer does not have a natural Blackjack, you lose your Insurance bet, and your hand is played out normally. If the Dealer has a natural Blackjack, you would lose your original wager, but win double the amount of your Insurance bet. Basically, you come out even. After you've been playing a while, you can determine whether the Insurance bet works for you or not.
