NAME            bj -- the game of black jack

SYNOPSIS        /usr/games/bj


        bj is a serious attempt at simulating the dealer in the

        game of black jack (or twenty-one) as might be found in

        Reno.  The following rules apply:

           The bet is $2 every hand.

           A player 'natural' (black jack) pays $3.  A dealer

           natural loses $2.  Both dealer and player naturals is

           a 'push' (no money exchange).

           If the dealer has an ace up, the player is allowed to

           make an 'insurance' bet against the chance of a dealer

           natural.  If this bet is not taken, play resumes as

           normal.  If the bet is taken, it is a side bet where

           the player wins $2 if the dealer has a natural and

           loses $1 if the dealer does not.

           If the player is dealt two cards of the same value, he

           is allowed to 'double'.  He is allowed to play two

           hands, each with one of these cards.  (The bet is dou-

           bled also; $2 on each hand.)

           If a dealt hand has a total of ten or eleven, the

           player may 'double down'.  He may double the bet ($2

           to $4) and receive exactly one more card on that hand.

           Under normal play, the player may 'hit' (draw a card)

           as long as his total is not over twenty-one.  If the

           player 'busts' (goes over twenty-one), the dealer wins

           the bet.

           When the player 'stands' (decides not to hit), the

           dealer hits until he attains a total of seventeen or

           more.  If the dealer busts, the player wins the bet.

           If both player and dealer stand, the one with the

           largest total wins.  A tie is a push.

        The machine deals and keeps score.  The following ques-

        tions will be asked at appropriate times.  Each question

        is answered by y followed by a new line for 'yes', or

        just new line for 'no'.

        ?               (means, "do you want a hit?")


        Double down?

        Every time the deck is shuffled, the dealer so states and

        the 'action' (total bet) and 'standing' (total won or

        loss) is printed.  To exit, hit the interrupt key (DEL)

        and the action and standing will be printed.
