Players can determine whether to hit or stand in less common scenarios by relying on basic strategy charts, which outline the mathematically optimal decisions for each hand based on the player's total and the dealer's upcard. In unusual situations, such as facing a dealer's weak upcard with a middling hand, players must consider the probabilities of busting versus the dealer's likelihood of drawing a stronger hand. Card counting can also provide additional insight by indicating whether the remaining deck favors high or low cards, helping refine the decision.
