Card Values
You can safely ignore the suits of the cards as they have no value in the game.
Cards 2 - 10 have a value the same as their face value.
All of the face cards (J,K,Q) have a value of ten.
Aces can have a value of either one or eleven.
A Jack and a four would equal 14.
An ace and a six would total either 7 or 17.
Hands with no ace are referred to as a Hard Hands because there is only one possible value.
Hands with one or more aces are called Soft Hands because there is more than one possible value.
If you draw a card to a soft hand and counting the ace as eleven puts you over 21 then the hand becomes a hard hand.
