If you feel the dealer has been a little too lucky, place your side bet in the area of the table marked insurance. The price of insurance is half the amount of the blind wager and pays 2-1 if the dealer proceeds to reveal a natural 21. If the dealer does not have blackjack, insurance bets are cleared before play continues. In blackjack, insurance is a side bet which is separate to your original stake. Offered only when the dealer's upcard is an ace, it acts as a safety net against an opposing blackjack. An insurance bet is usually half your original wager and pays 2 to 1. The side bet is completed when the dealer's second card is revealed.

I’ve written a few articles in the past that included advice that said you should never take insurance when you play blackjack. I stand by this advice because, for over 90% of the players who read my articles, the advice is 100% correct.

But I also need to present the other side of the argument to give you a complete understanding of insurance. The truth is that insurance is the correct play in a few specific situations. Most of these situations only become apparent to professional card counters, and because counting pros spend most of their time beating the casinos and not reading my articles, my advice of never taking insurance is correct for everyone else.

So why am I writing an article about taking insurance?

As you’re getting ready to learn, there are a few situations while playing blackjack when clearly it seems that taking insurance is a good bet. The odds are good that these situations are going to surprise you because they’re not why most players take insurance.

The Argument Against Insurance

The reason why taking insurance is a bad decision most of the time can be explained using simple math. But, as you’re going to see in the next section, this same simple math is used to show in a few situations that insurance is a good bet.

Explain Insurance In Blackjack

When the dealer has an ace, he or she offers insurance to the payers at the table. Insurance costs half of your original wager and pays 2 to 1 when the dealer has a natural blackjack. The only way the dealer has a natural blackjack is when his or her down card is worth 10 points.

The odds of the face down card being worth 10 points are 9 to 4 against. This is a percentage chance of 30.77% that the dealer has a blackjack. The reason why the odds are 9 to 4 is because of the 13 total card ranks, four of them are worth 10 points, and the other nine aren’t. The four 10-point value ranks are the face cards and the 10s.

Explain

When you compare 9 to 4 against the payout of 2 to 1, the casino has an edge. For the bet to be fair, the chances of the dealer having a blackjack need to be the same as the payout. The payout of 2 to 1 means that the percentage chance of the dealer having a blackjack needs to be 33.33%.

In any situation where the chance the dealer has a blackjack is over 33.33%, the insurance wager is a good bet.

The problem is that most of the time, the dealer doesn’t have a 33.33% or higher chance to have a blackjack. This goes back to how you compute the dealer’s percentage, or odds, based on the normal makeup of a deck of cards.

Determining the odds or percentages based on a normal distribution of cards in the deck sounds correct, but it assumes you don’t know the value of any cards. This is the safe way to do it, especially in a shoe game because a single card doesn’t change the odds or percentages much.

But what happens if you take the knowledge of cards played and remaining available in the deck or shoe into account?

Is there a way to use this information to determine when taking insurance is a good bet?

When You Should Take Insurance

Now that you understand how the math behind the insurance bet works, let’s look at a specific example where the bet changes from bad to good.

You’re playing in a single deck blackjack game.

  • On the first round of hands, you see the value of 14 cards. Only one of them is worth 10 points, so the remaining cards have 15 cards valued at 10. With 14 cards played, the deck has a total of 38 cards.
  • The second round of hands is dealt, and the dealer has an ace face up. You haven’t seen the value of the other player’s cards at this point, and you have a king in your hand. Now you’ve seen the values of 17 cards when you include the two in your hand and the dealer’s ace.
  • The remaining unseen cards total 35 and 14 of them are worth 10 points. This means that the odds of the dealer having a 10-point value down card are 21 to 14 or 3 to 2 against. In other words, 40% of the time the dealer is going to have a natural blackjack.

A winning insurance wager pays 2 to 1, so the odds are better than that in this hand. The 2 to 1 payout means that the chance of a dealer blackjack needs to be at least 33.3%, and in this example, the chance is 40%.

Explain Insurance In Blackjack

While this example is an extreme one to show when insurance is a good bet, you can also learn something from it. Now that you know that the chances of the dealer having a natural blackjack need to be 33.3% or higher, you can use this information in any single deck blackjack game. You can even use it in a double deck game if you do a good job of tracking cards.

This is much like card counting in that you don’t have to memorize every single card that’s been played. All you need to do is keep track of the ratio of total cards played to 10-point value cards. This even works in shoe games, but the truth is if you’re able to keep track of this ratio in shoe games, you should be counting cards.

How Important Is This Knowledge?

While it’s important to recognize and use every small advantage you can find, the truth is that the opportunity to take insurance with an edge is rare. If you play in single and double deck games often, it’s something that you should watch for.

But you should only concern yourself with profitable insurance opportunities after you do a few other things to lower the house edge. The first thing you should do is find blackjack games with good rules. The next thing every blackjack player should do is use basic strategy. It’s a waste of time and energy to worry about insurance before you do these two things.

Once you learn about the rules and learn how to use perfect strategy, then you can start looking for opportunities to take advantage of insurance. But even in this situation, I recommend looking for insurance opportunities as an introduction to learning more about counting cards.

When you start tracking card ratios, which is at the heart of determining when taking insurance is a good bet, you’re starting to use the same techniques card counters use. And the fact is that most popular card counting systems include a breakpoint where players start taking insurance.

In other words, a good counting system already has the insurance wager built in, so you know when to take it and when not to take it.

If you’re looking for every possible edge at the blackjack table, understanding how insurance works and when you should take it is important. But if you don’t want to do the extra work, then stick with good rules and proper strategy. By declining insurance every time, you’re not going to make a mistake often. When you do, it’s only going to cost you a small amount over time.

It’s a much more costly mistake to take insurance when you shouldn’t than to miss an opportunity to take insurance every once in a while, when it’s the correct play.

Conclusion

Taking insurance at the blackjack table is a bad bet most of the time. If you’re a basic strategy player or a seat of your pants player and don’t count cards, your best play is to always decline blackjack insurance. But as you can see from the numbers included in this article, there are certain situations when insurance goes from a bad bet to a good one.

Once you master basic blackjack strategy, start looking for opportunities where insurance is a good bet. When you start recognizing these opportunities, it’s a good sign that you’re ready to investigate card counting. It’s a small step from understanding and using what you learned above to become a successful card counter.

With simple rules and easy to learn strategies, the game of blackjack is one of the most popular card games in both Las Vegas Casinos and online around the world.

Blackjack side bets add a layer of complexity to the game, though at much greater risk.

In this article we’ll take a look at the different side bet options, how they are structured and what side bets pay.

What are Blackjack side bets?

Blackjack side bets are additional bets placed during a standard game of Blackjack. They involve predicting which cards the player, and sometimes the dealer, will receive.

Wagers are made before any cards are dealt and each side bet is based on chance rather than skill, although you can count cards to help you choose the most likely combinations for your best side bets.

Why play side bets?

One of the most attractive features of the game of Blackjack is the low house edge compared to other games on the casino floor.

Explain Insurance In Blackjack Winnings

Good players will face a house edge of around 0.5%, and even if you play quite badly, that edge only rises to around 2%.

However, while the odds of losing big are low, the odds of winning are also poor.

Blackjack is mostly an even money game, rising to 2:1 at best if you are dealt a Blackjack.

Side bets offer you the chance to play much longer odds for higher player wins – as much as 5,000:1 in one case.

However, it must be noted that the house edge rises significantly for Blackjack side bets, with most bets carrying a house edge of 10% or more.

In other words, side bets make it a lot easier to lose money on blackjack.

Common side bets at most Casinos

There are a number of common side bets that you will find at most Blackjack tables.

These are clearly marked with the odds either printed on the Blackjack tables or available as a hand out or a side menu in the online version.

You should check the pay outs carefully before placing your bets as they can vary considerably between different Casinos or online sites.

The three main Blackjack side bets are:

  • Insurance
  • Perfect Pairs
  • 21+3

Insurance – this is the most common Blackjack side bet and allows you to cover yourself against Blackjack if the dealer has an ace face up.

This bet involves half of your original stake and pays out at 2:1 if the dealer has Blackjack. The insurance bet reduces the overall house edge.

Perfect Pairs – this side bet uses the player’s cards only, and pays out if you are dealt two of a kind as follows:

  • Mixed pair (two of the same value but different suit and colour) – pays 5:1
  • Coloured pair (two of the same value and the same colour) – pays 12:1
  • Perfect pair (two of the same card) – pays 25:1

The returns can vary between different Casinos and different pay tables and the house edge will depend on both the pay out and the number of decks used and can range from just 2 or 3% up to 11% or more.

21+3 – this side bet involves the player’s two cards and the upturned card of the dealer. It will pay out for a number of different combinations:

  • Flush – (all cards are suited) – pays 5:1
  • Straight – (all cards consecutive) – pays 10:1
  • Three of a kind – (not the same suit) – pays 30:1
  • Straight flush – (consecutive cards same suit) – pays 40:1
  • Suited triple – (three of the same card) – pays 100:1

The house edge for the 21+3 side bet will vary depending on the number of decks used, standing at 8.78% for four decks, 7.81% for five decks, 7.14% for six decks and 6.29% for seven decks.

Other side bets to look out for

The Casino industry is highly competitive, and so new side bets are being invented all the time to try and attract new Blackjack players.

Some of these will flourish and become widely available, while others remain niche and can only be found in selected Casinos. Here are a few examples:

  • Royal match – pays 5:2 for any suited player’s cards and 25:1 for suited king and queen
  • Over/under 13 – pays even money for correctly predicting the sum of the player’s cards as less than or greater than 13. In most cases, exactly 13 will lose, but some Casinos will allow bets on exactly 13.
  • Super sevens – this bet pays out if one or more sevens are dealt in the player’s cards. One seven pays 3:1, two unsuited sevens pays 50:1, two suited sevens pays 100:1. If the third card dealt is also a seven, then the bet will pay 500:1 unsuited and 5000:1 suited. However it is important to make sure that the Casino will still deal a third card if the dealer has a Blackjack, as some Casinos will not do this.
  • Lucky ladies – this bet pays out if the player’s cards add up to 20, with an unsuited 20 paying 4:1, a suited 20 paying 10:1, a matched 20, same rank and suit pays 25:1, two queens of hearts 200:1 and two queens of hearts when dealer has Blackjack 1000:1.

Are Blackjack side bets worth playing?

Blackjack side bets do not involve any skill and you are simply betting on the luck of the draw.

What’s more, the returns do not reflect the odds of each bet coming in, which gives the house a significantly larger edge.

Conclusion

Blackjack side bets are best viewed as a bit of extra complexity that adds up to a session at the Blackjack table.

However, you should not make them the main focus of your gameplay or your wagering, and you should be aware of the significantly increased house edge.
