Split cards in blackjack are not only allowed, but they are actually one of the most common strategies used by dealers. In fact, dealers are allowed to split cards as long as the resulting hands still meet the basic criteria for being a blackjack hand.
For example, a dealer can split three cards to create a two-card hand and a four-card hand, or two cards to create a three-card hand.
The main reason dealers often split is to improve their chances of making a better hand. By splitting cards, the dealer increases the potential for getting an ace or a king.
Additionally, by splitting cards in blackjack, dealers can help offset their weaker hands and create more favorable hands.
