When you hear “insurance,” you probably think of your car or home. However, it might come as a surprise to many that insurance also applies to Blackjack. What then is Blackjack Insurance, and how can it be used at the table? This guide provides the answers.
Key Takeaways
- Insurance is a side bet offered when the dealer’s up card is an ace, paying 2:1.
- Odds of the dealer having Blackjack are approximately 30%. This makes insurance statistically unfavorable.
- Avoid using Blackjack Insurance unless you’re an expert at the table.
What Is Blackjack Insurance?
Blackjack Insurance is a side bet placed when the dealer shows an ace. It protects you if the dealer has a blackjack — a total of 21 with an ace and a ten-value card.
Insurance is a separate wager from your bet. It is usually valued as half of the original wager. If you take insurance and the dealer has blackjack, your bet will be paid 2:1. This mitigates the loss from the main bet. On the other hand, if the dealer does not have blackjack, you lose the insurance bet, and the regular hand proceeds.
Let’s use a $20 original stake as an example. You can place a $10 insurance bet if the dealer has an ace face-up. The $20 primary stake is lost if the dealer has a blackjack, but you are to going to win $20 from the insurance payout. However, if the dealer does not have blackjack, the insurance bet of $10 is lost, and the hand moves forward.
How Insurance Works in Online Blackjack
In online Blackjack, insurance becomes available when the dealer’s upcard is an ace. The process for placing an insurance bet is straightforward and occurs before players make any decisions about their hand, such as hitting or standing.
Online Blackjack games are either RNG-based or live-dealer formats. Both adhere to the same rules regarding insurance. In RNG-based games, a random number generator determines the dealer’s hole card. On the other hand, live Blackjack uses real cards dealt by a human. Regardless of the format, players sees an insurance prompt when the dealer shows an ace.
If you choose to take insurance, you have to do so before gameplay resumes. Also, know that insurance isn’t always a safety net. When the bet is lost and the hand continues, you lose money, which is regarded as a poor betting decision.
The Odds Behind Blackjack Insurance
Understanding the underlying odds and expected value is vital when considering blackjack insurance. Here’s all there is to know:
- When the dealer shows an Ace, they have approximately a 30% chance of having blackjack. This is calculated as 16 out of the 51 remaining cards being 10-value cards.
- The insurance bet pays 2:1 if the dealer has blackjack. However, this bet winning odds outweigh the 33.33% needed to break even.
- The house edge rises to around 7.4%. This is derived from the discrepancy between the insurance bet payout and the chances of the dealer having blackjack.
- The expected value (EV) of taking insurance is roughly -8.75% (single-deck game). For every $100 wagered, the player is expected to lose an average of $8.75.
- Due to the negative EV, consistently opting for insurance is statistically unprofitable over time. The bet favors the casino over the players.
Pros and Cons of Taking Insurance
Deciding whether to take insurance in blackjack can impact your game. Here are the key pros and cons to guide your choice before taking the insurance at the blackjack table.
Pros
- Limits Losses: Insurance has the ability to limit losses when betting large amounts, allowing you to break even if the dealer has blackjack.
- Protects Chip Stack: In tournaments or high-stakes scenarios, it protects your chip stack, maintaining competitiveness.
- Advanced players using card counting may benefit when the deck is rich in 10-value cards, increasing the dealer’s blackjack odds.
Cons
- Success has a low probability (30% in a single-deck game) unless you know the deck composition, which makes it risky.
- Insurance distracts from basic strategy, undermining long-term expected value.
- Blackjack Insurance extends the house edge (7.4% or higher) compared to the main game’s ~1%, it is particularly not advantageous for inexperienced players who bet emotionally rather than strategically.
When (If Ever) Should You Take Insurance?
Most experts advise against taking insurance in blackjack due to its high house edge. It goes from ~1% to approximately 7.4% by triggering the insurance clause in-game. For an average player, the odds significantly go against you.
The insurance wager is designed to protect against the dealer having a blackjack. However, from the house edge, we see that it is statistically in favor of the house. Therefore, taking insurance isn’t advised as you are disadvantaged by the odds. Making use of the insurance has the possibility of leading to an accumulation of losses over time.
However, there are exceptions to this rule. If a player is counting cards and knows that there are many 10-value cards in the deck, taking insurance is justified. In such cases, the dealer’s blackjack probability increases, making insurance potentially profitable. However, only use this strategy if you have a solid understanding of deck composition.
To sum up, insurance is not a wise bet for most players. It’s best to focus on basic strategies mastered using free Blackjack that offer better long-term outcomes. For average online blackjack players, declining insurance maintains a lower house edge and potential winnings.
