What Is Insurance in Blackjack?
Hardly any of you reading this does not know what insurance in blackjack is, but we will still refresh your memory of this moment the rules.
Insurance is offered to a player if a dealer opens an ace. If you think that he has a natural blackjack, you can protect yourself from a loss, by applying for insurance. It is equal to half of your original bet. If a dealer has blackjack, insurance is paid 2:1.
According to the basic strategy, insurance is disadvantageous for the player, so it is not recommended. However, not everything is so simple if you count cards. In such a case, you should not always refuse insurance.
When Should You Buy Insurance in BJ?
We will not go into lengthy mathematical calculations.
Let's just say that if you use a counting system of High/Low (also known as "Plus/Minus"), it is possible to make insurance if the TRUE count is above 3.3. According to the "halves", this value should not be less than 3.7.
If you are not using the system of card counting, you can consider tens remaining in the shoe. If the dealer's odds of having a ten are above one to three, purchase insurance. But it is better to use a standard card counting system.
What about Even Money in BJ?
There is also an option known as "even money " in most blackjacks."If you have a blackjack and the dealer opens an ace, he offers you a payout at the ratio of 1:1.
It is unnecessary to accept the proposal without counting cards since it means the average gain in the 26/27 ratio. As you can see, by refusing, you save 1/27 of beys.
The calculations mentioned above for insurance are valid for "even money." It is up to you to decide whether you should complicate the card counting process with this option. If you have just started mastering this technique, it is best to refuse insurance initially.
Finally, we note that there is insurance from the dealer's ten in some casinos. It would help if you always ignored it. This bet has a high house edge.
