In blackjack, soft refers to any hand that has an Ace in it. The Ace can count as either 1 or 11, so it gives the player a lot of flexibility in how they play their hand.
A soft hand is generally considered to be a good thing, because it gives the player a better chance of winning.
There are a few situations where soft hands can be a problem, though. For example, if the player is dealt a soft 18 (Ace-7), they might be tempted to hit, even though there’s a good chance they’ll bust if they do.
That’s why it’s important to know when to hit and when to stand on soft hands.
Overall, though, soft hands are considered to be an advantage in blackjack. If you’re dealt a soft hand, you should usually try to make the most of it.
