In Blackjack, winning hands typically consist of a total value of 21 or as close to it as possible without exceeding. The most coveted hand is a "Blackjack," achieved with an Ace and a ten-value card (10, Jack, Queen, or King) dealt as the initial two cards. Other strong hands include totals of 20 or 19, which can often secure a win against the dealer. Players must strategically decide to hit, stand, double down, or split pairs to maximize their chances of winning while navigating the dealer's hidden card.
