These can be tricky for a new blackjack player, as they have their own special rules (when it comes to doubling down, hitting, and standing). Soft hands are any hand with an ace with which the player can choose between 2 totals (for instance, A-4 could be either 5 or 15).
The player should hit a soft 13 through 17 if the dealer is showing 7 or higher. If the player has a soft 13 through 17, only double down when the dealer shows a 5 or 6.
Most of the time, the player should stand on a soft 18, although if the dealer is showing 9, 10, or A, the Player should take a hit. With the soft 18, always stand versus a 2, 7, or 8, and double down against a 3, 4, 5, or 6.
No matter what the dealer is showing, the player always should stand on a soft 19 or higher.
Finally, if the dealer holds a 2 and the player has a soft hand, do not double down.
