Should You Split 10s in Blackjack?

by Alex Thomas | The Gamble Times, updated 11th of June, 2025

TL;DR
Splitting 10s in blackjack is almost always a bad move. It goes against basic blackjack strategy, annoys the table, and usually costs you money long term. That said, in very specific advanced blackjack situations like card counting or high-stakes advantage play, there may be exceptions. But for most of us? Keep your 20 and let it ride.

The Temptation to Split 10s: We’ve All Been There

Picture it: you’re on a winning streak. You get dealt a pair of 10s. The dealer’s face-up card is a 5. The voice in your head whispers, “What if I split and double the win?”

That’s the adrenaline talking.

Splitting 10s is one of the most debated blackjack moves out there, right up there with taking insurance (don’t). But this one has some nuance. So let’s break it down.

What Does Basic Blackjack Strategy Say?

Here’s the short version: don’t split 10s.

Basic blackjack strategy, the one built on millions of computer simulations, says:

• A pair of 10s equals 20, one of the strongest hands in the game
• Only a 21 can beat you
• You’ll win or push most of the time

So why would anyone split them?

Usually:

• They’re feeling lucky
• They want to show off
• Or they’re chasing max profit in specific card counting situations

But unless you’re doing advanced blackjack plays with an edge, you’re just lighting chips on fire

Blackjack Etiquette: Splitting 10s Isn’t Just Risky, It’s Rude

Let’s be real. The table might glare at you if you split 10s.

Why?

• It disrupts the “flow” of the shoe
• It can potentially shift the odds for everyone
• It’s seen as a rookie flex or a reckless move, even if it occasionally pays off

Etiquette matters at the table, especially if you’re in a brick-and-mortar casino.

Pro tip: If you’re curious, practice high-risk blackjack plays at home or online first, not when others are putting real money behind their hands.

When Could It Make Sense to Split 10s?

Okay, here’s where it gets interesting.

There are some scenarios where advanced players might split 10s. Usually it’s when:

• You’re counting cards and know the deck is stacked in your favor. Highly discouraged, though.
• The dealer has a weak upcard, like a 5 or 6
• You’re deep in a high-limit advantage play setup and trying to squeeze every ounce of EV (expected value)

These are rare moments. If you’re not 100 percent sure of your edge, don’t do it.

This is not basic blackjack strategy. This is deep end, PhD-level blackjack.

Pros and Cons of Splitting 10s

Here’s the honest breakdown.

Pros (only if you know exactly what you’re doing):

• Possible to increase profits in advantage play scenarios
• Extra adrenaline, if that’s your thing
• Flex moment at the table, but also risky ego trip

Cons:

• Breaks basic strategy
• Lowers your win probability overall
• Can annoy your fellow players
• Big risk for small (or no) gain

What About Blackjack Online?

If you’re playing blackjack at online casinos like Thor Casino or Wolfy Casino, the etiquette part doesn’t matter as much. But the math still does.

Unless the game rules are weirdly stacked in your favor, which is rare, splitting 10s online is still a no-go.

Looking to test strategies? Try low-stakes tables or free demo blackjack games. Just don’t bring wild moves into real-money play unless you know the odds like the back of your hand.

Final Thoughts from Alex

Look, I get the rush. Splitting a pair of 10s feels bold. It feels like you’re taking control. But most of the time, you’re just giving the house an extra slice of your stack.

My honest advice? Stick to the 20. It’s one of the best starting hands in blackjack for a reason. Don’t let short-term excitement ruin a smart long game.

If you’re chasing the thrill, there are better ways to do it. Try side bets or explore more volatile slots (check out my review of CandySpinz Casino for some spicy picks).

Stay sharp,
