In blackjack, a soft 18 (an 18 that includes an Ace counted as 11, such as Ace-7) is usually played cautiously, as it’s a flexible hand. The general strategy for a soft 18 is to stand if the dealer has a 2, 7, or 8. If the dealer shows a weak card, like a 3 through 6, you can double down for a better chance to improve your hand. However, if the dealer shows a 9, 10, or Ace, you should typically hit, as their strong upcard puts you at a disadvantage with a soft 18. The goal is to improve your hand without risking a bust.
