How Splitting in Blackjack Works?

• Splitting Cards In Blackjack

What splitting in blackjack means is that when your hand consists of two cards with similar value, you can split them by placing additional bet, creating two hands that will be played separately. The option to split is of enormous value; if it’s used wisely of course. You can even double down a blackjack in some casinos. This rule applies whether you are playing blackjack live or playing online. A few casinos still restrict doubling down to a hard total of 9, 10, or 11. In these establishments, you can only double down if your first two cards total these amounts.

When to Split in Blackjack – Basic Strategy

We will try to make it simple to remember. Here we won’t explain the mathematics behind each decision, but you can find it in additional articles.

Most crucial ones:

• Never Split 5s and 10 value cards. (Double on 5s as you would on any hard 10).
• Always split Aces and 8s.

The easy ones to remember:

• 2s, 3s, 7s – split when dealer shows 2-7
• 6s – split on dealer’s 2-6.

And the unique ones:

• 4s – are not a perfect hand for splitting, so you should split them only when the dealer shows 5 or 6 and only when you can double after split. If the casino doesn’t allow to double on split hands – never split 4s.
• 9s – split on dealer’s 2-6 and 8,9.
