In blackjack, the basic strategy for deciding whether to hit or stand with a total of 12 to 16 depends on the dealer's upcard. When facing a dealer showing a weak card, like a 4, 5, or 6, players are generally advised to stand, as these cards are more likely to lead the dealer to bust, when the dealer has a stronger card, such as a 7 or higher, players should typically hit, as the risk of going bust is less significant compared to the potential for losing to a strong dealer hand. The overarching principle is to assess the dealer’s position while maximizing the chances of improving the player’s hand without exceeding 21.
