Pairs in Blackjack

Pairs – To Split or Not to Split, That Is the Question

Blackjack has multiple variations at both land-based and online casinos, but all versions of the game share some basic principles. Whenever the player is dealt two initial cards, there are several possible combinations, including a pair. As a skill-based game, blackjack allows players to reduce the house edge to its lowest possible level by using basic blackjack strategy. Optimal play also requires making the right decision with certain pairs. Some hands should be split, while other cards of the same rank are better played together.

Handling pairs correctly requires practice and a good understanding of these types of blackjack hands. Because pairs are common in the game, you may also encounter blackjack variations with side bets that pay when players are dealt a pair. This further underscores the importance of knowing how to play pairs correctly, which this article explains.

Pairs That Should Never Be Split

In blackjack, there are two pairs you should refrain from splitting under any circumstances, as doing so will likely leave you in a worse position. In general, you should split your hand only when you have a reasonable chance of making two strong hands. Therefore, when you receive a pair of 10s or 5s, you should avoid splitting because it will place you at a disadvantage.

A hand consisting of two 10s has long been the subject of debate. Over the years, many discussions have taken place because this pair can be tricky. Most gambling experts advise that whenever you get two 10s, it is best never to split them. Instead, you should always stand, regardless of the dealer’s up card. This is one of the best hands in blackjack, and splitting it would reduce your chances of winning.

Surprising as it may sound, a pair of 10s is one of the most misplayed hands in blackjack because many players fail to recognize its strength. Considering that the average winning hand is estimated at 18.5 points and that this pair totals 20, your best move is clearly to stand.

The other hand you should never split is a pair of 5s, although it requires a different approach. If you split the pair, you will most likely end up with two hands that have little chance of reaching a strong total. Initially, a pair of 5s gives you a total of 10, which provides a fairly good start. However, splitting this hand would turn one strong hand into two weak ones.

Instead of splitting, you should double down or hit, depending on the dealer’s up card. If the dealer is showing two through nine, you should double down because the dealer is in a weak position, and you should capitalize on it. This gives you the chance to increase your wager when the odds are in your favor. If the dealer shows a 10 or an ace, it is best to hit and try to improve your hand.

Pairs That Should Always Be Split

Unlike hands containing a pair of 5s or 10s, some situations always require splitting. For instance, whenever you have a pair of 8s, you should always split. Most proficient blackjack players agree that you should split a pair of 8s regardless of the dealer’s up card. However, this combination is considered one of the trickiest hands. It is important to take your time and consider the possible moves carefully.

A pair of 8s gives you a total of 16. On the one hand, this total probably is not enough to beat the dealer, considering that the average winning hand is 18.5 points. On the other hand, if you attempt to improve it by taking another card, your chances of exceeding 21 and busting are high.

Another hand that should be split consists of two aces. The ace is the most powerful card in the deck, so whenever you have such a pair, it is essential to know your best option. Knowing how to proceed in these challenging situations will help you get the most out of every game.

You should always split paired aces, regardless of the blackjack variation you play or the dealer’s up card. A pair of aces is a soft hand that totals 12 or 2 because aces can count as 1 or 11. Therefore, it is better to split paired aces and form two separate hands, each with a strong starting value of 11. This improves your chances of winning by allowing you to play two strong hands simultaneously. In addition, you have a very good chance of drawing a ten-valued card and forming a two-card total of 21, as a single deck contains sixteen ten-valued cards. Of course, there are a few exceptions to this rule. If you play a no-hole-card game, you should hit your paired aces if the dealer’s up card is an ace and split in all other cases.

Important Considerations

Blackjack is a card game with many variations that are as widespread and popular as the classic version. These games use the same basic rules as the original but may also introduce additional rules and features. One rule that can vary by blackjack version and casino concerns splitting. This is why you should always double-check the rules of the game in advance and identify any restrictions that favor the casino.

Some variations impose restrictions on the number of times you may split or the types of cards you are allowed to split. You should also double-check whether doubling down after splitting is permitted and whether you are allowed to split aces. In general, if you are denied the option to split a pair, the house edge increases by approximately 0.57%. If splitting aces is not allowed, this also works in favor of the casino, increasing the house edge by 0.10%. If you are allowed to re-split aces, this is beneficial because it gives you an advantage of 0.32%.

Conclusion

While playing blackjack, you will inevitably be dealt a hand consisting of two cards of the same value. If you want to handle these situations successfully, you should prepare in advance. It is highly recommended that you learn all the possible moves so you know which options are best and which to avoid in each situation. For instance, when you have a pair of 10s and know that hitting carries a high risk of busting, you will avoid this move. Mastering basic strategy will help you determine when splitting is the optimal decision, but you should remember that splitting does not guarantee a win.
