We’ve already covered how to split a hand when you get dealt a pair of 10 cards or two, regardless of which face. Each new hand is played the same as an ordinary one. While there are some exceptions to the rule, such as limiting the number of resplits and allowing resplitting of aces only, the general rule is that they can be played just like any other hand.
Like in every other scenario of basic strategy, will decide whether to split a pair or not based on the pair and the relevancy to the up-card.
Do not split 10s
Splitting 10-10 hands defies logic, unless you’re a card counter. For employers who are familiar with basic strategy, it is best to never lose a hand that is close to perfect. Simply calculating the odds of the dealer getting a blackjack or multiple-card 21 in your favor against your 10-10 is simple math.
Once they identify a situation where splitting their hand will give them an advantage, card counters are more likely to split 10s. If you don’t count cards , there is no reason to split 10s .
Basic strategy dictates that you split 9s against any numeric card the dealer has except for a 7. This is because a dealer holding a seven has a high chance of holding a 10, which will allow him to stand on his hard 17. Your 9-9 will win.
Even if the dealer has a hole card of 10, there is still a chance that he will get a strong hand (with 9, 8, 7, 6, 5) and a high likelihood of going bust.
Splitting your 9s with the dealer’s 9 is an excellent choice as your 18 can easily beat by a 10-hole card.
Splitting 8s can be tricky but it is the best choice for this hand. An 8-8 hand is the most difficult to play. It faces the greatest number of cards that could break it,. But hitting an 8 is easier and has a good chance of turning into a great hand.
Split 8-8 will increase your chances of winning and ultimately make you lose less. If the dealer does not have a strong hand, an 8-8 hand is likely to be a loser.
Splitting and drawing a 10-card or a 9, will increase your chances of getting a push, or beating a dealer’s 17. You can also hit again if you draw a low-card card like an Ace or 2 or 3. If you have only one hand that develops as described, you can break out of the bad hand at breakeven. This is a fantastic outcome after a tough 16.
Splitting 7s and6s
Splitting 7s or 6s against a dealer’s up card of 2-7 is done for many reasons. 7s and 6s can be very stiff starting hands, which can lead to you getting busted on hitting. A dealer who holds a 2-7 hand has a greater chance of getting a stiffer hand. It is a smart idea to split your hand and try your luck at a stiffer dealer.
Do not split 5s
Avoid splitting 5s and 10s unless your are a card count. If you have a 5-5 hand, it is a good chance to double down and increase your chances of winning a high-range hand (18-21).
Splitting the 5s leaves you with two stiff hands (all 10, all 9s and all 8s can make stiff hands). You will need another 5 or 6 to double down those hands (to make the total value 10-11). Two 5s have been removed from the deck.
Splitting 4s is more difficult
The rules for splitting a 4-4 hand depend on whether you are allowed to double down after splitting. You should split 4s in a DAS game against the dealer’s up card of 4, 5, or 6. Splitting a hand with DAS allows you to split 4s against the dealer’s up-card of 4, 5, or 6. A 4-4 hand is not allowed if you want to double down on a split. However, 8 starting hands is better than 2 starting hands of 4.
Splitting 2s or 3s
Double down is permitted after a split. 2-2 and 3–3 hands are divided against a dealer’s up-card of 2-7. There are several reasons why this is so. A good way to increase your chances of getting a double-down against the weak up-card dealer is by hitting a 2 or 3. A pair of 2s and 3s is a bad starting hand, as hitting a 10 or 9 for 3s will give you a stiff hand. A dealer with an up-card of 2-7 has a good chance to get a stiff hand.
