In Blackjack, insurance is a side bet offered when the dealer's upcard is an Ace. It allows you to wager up to half of your original bet that the dealer has a Blackjack. However, in most cases, it is not advisable to take insurance. The odds are not in your favor, as the payout for an insurance bet is 2:1, but the probability of the dealer actually having a Blackjack is too low to make it a worthwhile bet. Basic strategy generally recommends avoiding insurance because it increases the house edge over time.
If you're a card counter, insurance bets become more appealing when the deck has a higher proportion of 10-value cards left. In such situations, taking insurance can be profitable, as the chances of the dealer having a Blackjack rise. However, without card counting, it’s usually best to decline the insurance offer, as the bet is mathematically disadvantageous. In short, unless you're counting cards and the deck favors you, insurance bets should typically be avoided.
