The dealer must play his hand according to very specific rules.  There
are two basic rule variations that determine what hand total the dealer
must draw to.
Dealer stands on all 17sThe dealer must continue to draw cards (hit) until the
hand total is at least 17.Dealer hits soft 17The dealer must continue to draw cards (hit) until the
hand total is at least 17, except when the dealer has a soft total of 17
he must take another card.
A soft total is one where an Ace card is counted as an 11.
