In blackjack, insurance is a side bet offered by the dealer when the dealer’s upcard is an ace. If the dealer has a blackjack (a hand consisting of an ace and a 10-point card), the insurance bet pays out at 2-1 odds, meaning that if you bet $10 on insurance and the dealer has a blackjack, you would receive $20 back (your original $10 bet plus the $10 payout).
If the dealer does not have a blackjack, the insurance bet is lost and play continues as normal. The idea behind taking insurance is that it allows you to protect yourself against the dealer having a blackjack, which would result in your losing the hand.
However, the insurance bet is generally not a good idea for the player, because the probability of the dealer having blackjack is only about 31%. This means that you are more likely to lose the insurance bet than win it, and the payout of 2-1 is not enough to make up for the negative expected value of the bet.
Overall, insurance is a side bet in blackjack that allows you to protect yourself against the dealer having a blackjack, but it is not generally a good bet for the player due to its low expected value.
When to take insurance in blackjack?
As a general rule, it is not a good idea to take insurance in blackjack, because the probability of the dealer having a blackjack is relatively low and the insurance bet has a negative expected value for the player.
However, there are some situations in which taking insurance might be the correct decision, depending on the specific rules of the game and the player’s overall strategy.
For example, if the player is counting cards and knows that the probability of the dealer having blackjack is higher than usual, taking insurance might be a good idea. Card counting is a technique in which the player keeps track of the cards that have been played in order to determine the likelihood of certain cards appearing in the deck. By keeping track of the cards that have been played, the player can make more informed decisions about their bets and play.
Another situation in which taking insurance might be the correct decision is if the player has a strong hand and wants to protect their bet against the possibility of the dealer having a blackjack. For example, if the player has a hand worth 19 points and the dealer’s upcard is an ace, taking insurance might be a good way to protect the player’s bet and potentially win back some of their money if the dealer does have a blackjack.
Overall, while taking insurance can be a tempting option in blackjack, it is generally not a good bet for the player due to its negative expected value. It is important to consider the specific rules of the game and the player’s overall strategy before deciding whether to take insurance.
Why insurance should generally be avoided in blackjack?
Insurance is a side bet offered by the dealer in blackjack when the dealer’s upcard is an ace. If the dealer has a blackjack (a hand consisting of an ace and a 10-point card), the insurance bet pays out at 2-1 odds. If the dealer does not have a blackjack, the insurance bet is lost.
There are a few reasons why insurance should generally be avoided in blackjack:
- Low probability of success: The probability of the dealer having blackjack is only about 31%, which means that you are more likely to lose the insurance bet than win it.
- Poor payout: Even if you do win the insurance bet, the payout of 2-1 is not enough to make up for the negative expected value of the bet. In other words, the insurance bet is not a profitable bet in the long run.
- Distracts from the main goal: The main goal of blackjack is to beat the dealer by having a hand that is worth more points than the dealer’s hand, without going over 21. Taking insurance can distract from this goal and cause the player to focus on the insurance bet rather than their own hand.
- Takes money away from the main bet: When you take insurance, you are placing an additional bet on top of your original bet. This means that you are effectively splitting your money between two bets, which can reduce the potential payout on your main bet if you win.
Overall, while taking insurance can be tempting, it is generally not a good bet for the player due to its low probability of success and poor payout. It is usually better to focus on the main goal of blackjack, which is to beat the dealer by having a hand that is worth more points than the dealer’s hand.
