Split cards are a great way to increase your chances of winning in blackjack. When you split aces and face cards, you’re increasing your potential for making a high hand.
However, there is one caveat to splitting face cards in blackjack – if the dealer has two face cards of the same rank, they can always give you a two-card combination that would beat your original hand. For example, if the dealer shows a two of clubs and a two of spades, you would still lose with an original hand of two queens.
In general, it’s best to avoid splitting face cards if the dealer has any other kind of good hand. If the dealer has an ace and a two, for example, splitting the face cards would only give you an Ace high hand which is generally not as good as either of your original hands.
