Yes, you can split Aces in Blackjack, but there are some specific rules around it. When you split Aces, you are essentially turning one hand into two separate hands, each starting with an Ace. However, most casinos only allow you to receive one additional card for each Ace after the split.
Additionally, if you draw a 10-value card (10, Jack, Queen, or King) to one of your split Aces, it typically doesn’t count as a Blackjack (which requires an Ace and a 10-value card as the initial two cards). Instead, it’s just a regular 21. Also, many casinos do not allow you to resplit Aces or double down after splitting them.
The general idea is that splitting Aces gives you a better chance to form two strong hands, but the restrictions make it a bit less favorable than splitting other pairs.
