Blackjack Basic Strategy - Duke's Black Jack Basic Strategy

HARD HANDS: all hands not containing an Ace.
SOFT HANDS: all hands containing an Ace coupled with a 2, 3, 4, 5, 6, 7, 8, or 9.
PAIRS: all hands that contain a pair of cards with the same value. A simplified approach to basic blackjack strategy is as follows:

HARD HANDS:
If you have a 9 or lower, hit.
If you have 10 or 11, double down if your total is more than the dealer's upcard; hit otherwise.
If you have 12 through 16, hit when the dealer's upcard is 7 or higher; stand otherwise.
If you have 17 or higher, stand.

SOFT HANDS:
If you have 13 through 18, double down when the dealer's upcard is 5 or 6.
If you have 17 or lower, hit.
If you have 18, hit when dealer's upcard is 6 or less; stand when dealer's upcard is 7 or more.
If you have 19 or higher, stand.

PAIRS:
Always split a pair of 8's or Aces.
Never split 10's, 4's, or 5's.
Split all other pairs when dealer's upcard is 6 or less.
