When playing multiple hands in Blackjack, the strategy remains similar to playing a single hand, but there are a few key adjustments. You'll need to manage your bankroll carefully, often lowering your bet per hand to spread out your risk. Doubling down is still a good option for strong hands like 9, 10, or 11, but it’s best not to double down on every hand to avoid overexposure. Splitting pairs follows the same basic rules, but you should consider the risk of splitting if you already have other strong hands in play. Each hand should be treated independently, so you make decisions based on the individual situation of that hand, such as hitting on weaker hands and standing on stronger ones. Overall, while the core strategy doesn't change, managing multiple hands requires balancing each decision to optimize your chances while protecting your bankroll.
