Insurance bets in blackjack can impact overall strategy by offering a side bet when the dealer shows an ace, but they are generally viewed as a poor long-term choice due to unfavorable odds. While the payout for insurance is 2 to 1, the actual probability of the dealer having a blackjack is lower, resulting in a negative expectation for the player. Incorporating insurance can distract from fundamental gameplay and lead to increased bankroll volatility. Most strategic approaches recommend against taking insurance unless a player has a strong grasp of card counting, as it can undermine effective bankroll management and gameplay efficiency.
