In blackjack you will sometimes hear of players who insist on insuring their blackjack against a dealer’s Ace. They perceive it as guaranteeing that they will receive a payout, that in that they are saving money and their blackjack odds.
However, they will lose money and take a hit to their blackjack odds in the long run. And it is all in the math.
Part of what helps a player’s basic blackjack odds is that they receive a 3-2 payout when they are dealt a natural blackjack, while the dealer does not receive a payout when he is dealt a natural blackjack. Blackjack odds are based on a player’s opportunities to make money. The better the opportunity the more it improves your blackjack odds.
This is why receiving a 3-2 payout is so important. It is always why players should avoid blackjack games and variations that do not offer a 3-2 payout.
When you take insurance on your blackjack against a dealer’s Ace you are giving up your chance of receiving that 3-2 payout for the guaranteed even money. Players who believe in taking that even money just to make sure they are getting money feel that if they are receiving some money so they must be doing good. After all, receiving money is good right?
Actually in this case it is wrong. Taking even money, a 1-1 payout, for a natural blackjack can have a big negative impact on your blackjack odds. How big? A 1-1 payout for a blackjack hits your odds for 2.27%.
So you have a choice. You can take the even money and the 2.27% hit to your blackjack odds, or you can decline insurance and take the chance at the 3-2 payout and keep a hold of your odds.
