How to Play a Pair of 10s in Blackjack

At LeoVegas, online blackjack remains one of the most popular casino games for players in Ontario. Whether you’re playing on your laptop, tablet, or phone, the game offers a great mix of chance and strategy.

While the cards you’re dealt are random, the decisions you make can dramatically affect your results over time. Players who follow basic blackjack strategy can reduce the house edge to around 0.5% in many standard games, making blackjack one of the most player-friendly casino games available.

Few starting hands feel more exciting than seeing two 10-value cards, whether that’s two 10s, two face cards, or a mix like a King and Queen. Together they form a total of 20, one of the strongest hands in blackjack. But here’s the question that gets debated at almost every table:

Should I split 10s in blackjack?

Or, phrased another way: Do you split 10s in blackjack?

For almost all players, the short answer is: stand.

In this guide, we’ll explain why that’s usually the smartest move, break down the maths behind it, explore the psychology that tempts players to split, and compare 10s with other common pairs, so you’ll know exactly how to play your pair of 10s.

Do You Split 10s in Blackjack?

Since we’ve already covered the short answer to “Do you split 10s in blackjack?” (which is to stand), it’s worth taking a closer look at the longer explanation and why that strategy works.

A pair of 10s gives you a total of 20, which is already one of the strongest hands you can have in blackjack. Splitting the pair breaks up that powerful total and turns it into two separate hands that still need strong cards to succeed.

Because of this, players wondering whether they should split 10s in blackjack will find that basic strategy gives a very clear recommendation: stand on 20 and keep the hand together.

You might occasionally hear about expert players splitting 10s in very specific situations involving card counting in land-based casinos. However, those conditions rarely apply to online blackjack, where games typically use multiple decks and random shuffling.

For most online players, the strategy remains simple: protect your 20 and let the dealer play their hand.

The Importance of 20

Now that we’ve looked at whether you should split 10s, it helps to understand why a total of 20 is such a strong position in blackjack.

In the game, a hand worth 20 is incredibly powerful. It’s the second-best possible total, beaten only by a natural blackjack (21).

There are two main reasons why this hand is so valuable.

First, the winning probability is extremely high. A total of 20 wins the majority of hands, typically around 85–92% depending on the dealer’s upcard and the specific game rules.

Second, the profit potential is strong. When you stand on 20, you’re protecting a hand that already puts the odds heavily in your favour.

Despite this advantage, some players still feel tempted to split their 10s, especially when the dealer shows a weak upcard like a 5 or 6. At first glance, it might seem like splitting could create two winning hands instead of one.

However, the maths shows that your original 20 is already a highly profitable position. Breaking it apart simply introduces unnecessary risk. To see exactly why this matters, it helps to look at the concept of Expected Value, which explains how blackjack decisions perform over the long run.

The Expected Value Explained

To really understand why splitting 10s is rarely the right move, it helps to look at the maths behind blackjack decisions. This is where Expected Value (EV) comes in.

Expected Value measures how profitable a decision is over the long run. A move with a higher EV will generate better results over thousands of hands, while a lower EV decision gradually works in the casino’s favour.

When holding a pair of 10s, the key comparison is between standing on 20 and splitting the hand into two separate bets.

Standing on 20

Standing on 20 carries a very strong positive expected value. For example, when holding 20 against a dealer’s 6, the EV of standing is roughly +0.65 to +0.70 relative to your original bet, depending on the game rules.

Since your hand is already extremely strong, standing simply protects that advantage and lets the dealer try to beat a very difficult total.

Hitting on 20, on the other hand, almost always results in a bust. Only an Ace can improve the hand safely, which makes taking another card an extremely risky move.

It is also worth remembering that standing on a 20 can act like insurance if the dealer is only able to hit 20 as well. In this scenario, the round would end in a push, returning your money.

Splitting 10s

Splitting 10s changes the situation completely. When you split:

• You place an additional wager equal to your original bet.
• The dealer separates the pair into two new hands, each starting with a single 10.

While these hands may still have potential - particularly against weaker dealer cards, they are not as strong as the original total of 20.

Over the long run, splitting 10s lowers your expected value and increases the house edge. That’s why standard blackjack strategy recommends keeping the pair together and standing on 20.

Why Do Players Split?

After looking at the maths and expected value, the strategy seems obvious: keep your pair of 10s together.

But, blackjack isn’t played by calculators; it’s played by people. And sometimes psychology can influence decisions just as much as statistics. That’s why some players still choose to split their 10s, even when the numbers suggest they shouldn’t.

Overconfidence Against Weak Dealer Cards

One of the most common reasons is overconfidence when the dealer shows a 5 or 6.

Because these cards increase the dealer’s bust risk, players often feel they have a clear advantage. Splitting might seem like a way to maximise profits by creating two potentially strong hands instead of one.

However, this thinking overlooks an important point: your original hand is already very likely to win.

By splitting, you’re turning one strong hand into two uncertain ones, which actually reduces your long-term advantage.

The “Dealer Bust” Fallacy

Another common misconception is that the dealer will almost certainly bust when showing a 5 or 6.

In reality, the dealer still completes a hand more often than they bust, even with these weaker upcards.

Relying on the dealer to bust rather than protecting your strong total of 20 is a classic blackjack mistake — and one that can slowly erode your winnings over time.

Are There Any Exceptions?

At this point, you might still be wondering whether there are any situations where splitting 10s makes sense.

For most online blackjack players, the answer remains straightforward: no.

There are two scenarios sometimes mentioned in advanced blackjack strategy discussions, but they rarely apply to standard online play.

Card Counting

In land-based casinos, expert card counters may occasionally split 10s when the remaining deck is heavily weighted towards high cards. This increases the chances of drawing another 10 or an Ace.

However, this strategy requires advanced tracking of the deck and very specific conditions, which are not present in most online blackjack games that use multiple decks and computer-generated shuffling.

Tournament Play

In blackjack tournaments, players compete against each other rather than just the dealer. Because chip totals determine the winner, players sometimes make aggressive decisions, including splitting 10s, in order to increase variance and build their stack quickly.

For standard online blackjack games, however, neither of these scenarios is usually relevant.

The safest and most profitable approach remains simple: stand on 20 and keep the pair together.

10s vs Other Pairs

To fully understand why 10s should stay together, it helps to compare them with how other pairs are typically played in blackjack.

Aces → Always Split

A pair of Aces totals 12, which isn’t a strong starting hand. Splitting them gives you two chances to build powerful totals such as 19, 20, or 21.

8s → Always Split

Two 8s equal 16, widely considered one of the worst hands in blackjack. Splitting creates two new hands and gives you a chance to escape a difficult situation.

10s → Never Split

A pair of 10s already gives you 20, one of the best hands in the game. Breaking that hand apart only reduces your advantage and increases your risk.

Whenever you find yourself wondering “Do you split 10s in blackjack?”, the best move is almost always the same: stand on 20 and let the dealer play their hand.

Side Bets and Optional Features in Online Blackjack

Many online blackjack tables offer side bets such as Perfect Pairs, 21+3, or other optional wagers.

While these features can add extra excitement, they don’t change the core strategy for playing your hand.

A few things to keep in mind:

• Side bets are independent of your main blackjack hand.
• Your strategy for playing 20 remains exactly the same.
• Basic blackjack decisions should always come first.

In short, even if you enjoy the occasional side bet, your pair of 10s should still stay together.

Key Takeaways

If you remember just a few things about playing a pair of 10s in blackjack, make them these:

Protect your 20

A total of 20 is one of the strongest hands in blackjack and wins the majority of the time.

Trust the maths

Standing on 20 offers strong positive expected value, while splitting reduces long-term profitability.

Ignore dealer bust myths

Even when the dealer shows a weak card like a 5 or 6, they still complete a hand more often than they bust.

Follow the basic pair rules

Always split Aces and 8s, but never split 10s in standard blackjack strategy.

Side bets are optional

They can add excitement, but don’t change the correct play for a pair of 10s. Whether you’re playing classic blackjack, speed blackjack, or another variant at LeoVegas, understanding these fundamentals can make a real difference to your results.

So the next time you’re dealt a pair of 10s, play it with confidence: keep the hand together, stand on 20, and let the maths work in your favour.
