In Blackjack, the terms "soft" and "hard" refer to the type of hand the player has, based on the presence of an Ace and how it can be counted.
A soft hand includes an Ace that can be counted as either 1 or 11 without the risk of busting. For example, a hand with an Ace and a 6 is a soft 17 because the Ace can be counted as 11 (giving a total of 17), or as 1 (giving a total of 7). Soft hands are more flexible since the Ace can adjust to avoid busting.
A hard hand, on the other hand, does not contain an Ace, or if it does, the Ace is counted as 1 because counting it as 11 would cause the hand to bust. For instance, a hand with a 10 and a 7 is a hard 17, and if the hand contains an Ace like Ace-6-10, it would be a hard 17 as well, because the Ace would be counted as 1.
