In blackjack, "insurance" is a side bet offered to players when the dealer's upcard is an Ace. It allows players to bet up to half of their original wager, anticipating that the dealer's face-down card will be a ten-value card, giving the dealer a blackjack. If the dealer does have blackjack, the insurance bet pays out at 2 to 1, allowing players to recover some of their losses. If the dealer does not have blackjack, the insurance bet is lost, and the game continues as usual. This option is often seen as a way for players to protect themselves against the risk of the dealer having a strong hand.
