A split is an action that allows you to split your hand into two when cards with the same number are dealt . In other words, you will be competing with two sets of hands. In Blackjack, 10, J, Q, and K are all treated as 10 counts, so even if you have 2 of the 4 types in your hand, you can execute it.
Example: Splittable hands (6,6) (10,Q) (J, K)
However, depending on the casino, there are places where you can only do it with the same number, so you need to confirm in advance.
When you make a split, you must spend the same amount as you originally bet . For example, suppose you first bet $ 10 and get distributed (8,8). In addition, if you bet an additional $ 10, you can play in two hands like (8,?) (8,?). After the cards for the missing hands are dealt, the actions such as stand and hit are performed as usual.
Blackjack split constraints
① Resplit (split again)
If another hand with the same number is dealt in the hand after the split – for example (9,9) and 9 and 10 are dealt in the hand after the split. When the situation of (9,9) (9,10) is reached, split the hand again and divide the hand, and re-split to make three hands (9,?) (9,?) (9,10). Is called.
This may or may not be possible depending on the casino, so it is essential to check the rules.
② Ace (A) split
When dealt with (A, A) by hand
A is the most powerful card in blackjack because it has the property of changing numbers from 1 to 11 depending on the situation. If you can split with (A,?) (A,?), If the next card is “10 or a picture card”, it will be 21, which is very advantageous. Therefore, please note that A is limited to being a forced stand after only one hand is dealt after the split.
③ Double down after splitting
Double down is an action that limits the next card you can draw to only one, instead of doubling your stake. Double down after split has different rules depending on the casino, so it is necessary to confirm whether it is possible or prohibited.
When should Blackjack split be done?
While the hands can be paired from [A] to [K], the action to be taken depends on the number. You need to make a judgment by comparing the number of one face-up card dealt to the dealer with the number of your hand. The probability is calculated based on the rule that the dealer must hit 16 or less and stand 17 or more .
In the case of pair hand A : In any situation, the split of the split
ace will be 1 or 11 as mentioned above, and if 10 or a picture card comes in the next card, you will win, so splitting is more advantageous. By the way, it is said that the probability that 10 and a picture card will come is about 30%.
For pair hand 10 and picture card : 20 at the time of the hand, so there is a high chance of winning and there is no need to split.
In the case of pair hand 9 : When 2, ~ 6,8,9 are up cards, the
total number of splits is 18, so there is a possibility of winning with a high card, but it will be judged depending on the situation of the up cards. The reason 7 is excluded is that if 10 comes, the dealer’s total will be 17 and there is a good chance of winning the forced stand.
For paired hands 8 : In any situation, a
total of 16 split hands have no chance of winning except for the dealer to burst, so it is better to split and increase the winning percentage.
In the case of pair hand 7 : When 2 to 7 are up cards
, the total number of splits is 14 and it is halfway. Even if it hits, it is difficult to become 21 because 7 is already in the hand.
For pair hand 6 : Split when 2 = 6 is an up card Since
there are statistics that it is easy to burst when the dealer is 2 ~ 6, split to avoid hitting and bursting yourself.
For pair hands 4 and 5, do not split If the
next card is 10 or a picture card, it will be 18 or 20, so it is easy to win with a high card. Therefore, avoid splitting into a weak hand.
For pair hands 2 and 3 : Split when 2 to 7 are up cards Even if you
hit as it is, the total number is likely to be weak, so expect to split and become a stronger hand.
