Cards to Always Split:
* Aces: Splitting aces gives you two separate hands, each with the potential to make 21. You'll receive one card for each ace and then decide how to play each hand.
* 8s: Having two 8s gives you a total of 16, which is a very weak hand. Splitting gives you two hands with a better starting point.
Cards to Usually Split:
* 2s, 3s, 7s: These cards offer a chance to improve your hand by getting closer to 21. However, keep the dealer's upcard in mind (more on this below).
* 9s: Splitting 9s is usually a good play if the dealer's upcard is 7 or lower. It increases your chances of getting a strong hand.
Cards to Sometimes Split:
* 6s: Splitting 6s is usually a good idea if the dealer's upcard is 7 or lower. However, if the dealer has 10 or Ace, it's generally better to stand.
* 4s: Splitting 4s can be good if the dealer's upcard is 5 or lower. It's generally not a good idea if the dealer has a high card.
Important Considerations:
* Dealer's Upcard: The dealer's upcard significantly influences splitting decisions. If the dealer has a low card, it's more likely they'll bust, making splitting a more attractive option. If they have a high card, it's riskier to split.
* Table Rules: Some casinos have different rules about splitting, like whether you can double down after a split or how many times you can re-split. Always check the table rules before making any decisions.
* Card Counting: If you're a card counter, you'll factor in the count to make your splitting decisions.
General Rule of Thumb:
* Split: When your hand is weak, splitting gives you two chances to improve.
* Don't Split: When your hand is strong or if you're concerned about the dealer's upcard.
Remember: Blackjack is a game of probabilities, and there's no foolproof strategy. The decisions you make should be based on the specific circumstances of the hand and the table rules.
