A soft hand in blackjack refers to a hand that contains an Ace valued as 11 without busting. This means that the Ace can be adjusted to count as either 11 or 1, providing flexibility in the total value of the hand. For example, an Ace and a 6 form a soft 17, allowing the player to hit without the immediate risk of going over 21. Soft hands give players more strategic options during play, as they can afford to take risks without the fear of busting in the same way as with a hard hand, where the value is fixed and does not include an Ace as 11.
