In blackjack, when dealing with a soft 17 (an ace and a six), the decision to hit generally depends on the dealer's upcard. If the dealer shows a strong upcard, such as a 7 or higher, it's often advisable to hit because the likelihood of improving your hand is greater. Conversely, if the dealer's upcard is weaker, like a 2 through 6, the strategy might suggest standing, as the dealer is more likely to bust, thus maximizing your chances of winning without risking the hand you currently have.
