Black Jack Basic Rules

The player and dealer are both dealt 2 cards (1 of dealers is hidden).
The closest to 21 after the game is finished wins.  A Black Jack or
"Natural" occurs and pays 3:2 if a hand contains an Ace (1 or 11 value) and
 a Ten. 10's and all face cards count as 10, 2 thru 9 are their face value.

HIT:  Take 1 card.

Stand:  Hold what you got.

Double:  You double your bet and get 1 additional card ONLY.

Split:  You split your 2 cards into 2 seperate hands and double your
bet.  You will receive another card on each and play as above on each.

Insurance:  If the dealer shows an Ace up you can bet that the dealers hand
is a Natural, the bet is 1/2 your bet and if you win you win
2:1 and lose your other bet (effectively breaking even).
