Insurance in Blackjack
A game of blackjack is quite dependent on the situation of the game itself and is required when a dealer shows an ace. This insurance is dependent on the belief that a dealer has a blackjack. In order to take an insurance you are required to place on a table half of the amount that you betted. If a dealer does have a blackjack then you get back the betted amount. Conversely, if a dealer lacks any blackjack then you lose the insured amount and have to continue with the rest of the game.
The picture below depicts a situation in which the dealer asks the other players of whether they are willing to take insurance or not. The dealer does so by saying "insurance open" and end by saying "insurance closed". Within this time frame the player is required to get insured. In the online version you shall encounter this as well; this starts from the right side and continues in Yes or No format.
This option is mainly used when a blackjack is present in the player's hand. The term "I will take even money" is used by the player to get the initial amount that they betted. Conversely, if a dealer has a blackjack then they can win the insurance. Absence of a blackjack in the dealer's hand makes the player lose the insured amount.
