Michael Shackleford: Hi guys, this is Mike and the purpose of today's Wizard of Odds Academy lesson will be to explain why you should never take insurance in Blackjack. What insurance is, is a side bet that the dealer has a 10 point card in the hole.

It is offered when the dealer already has an ace up, so it wins in the event that the dealer gets a blackjack. The insurance bet can be made for up to half of the player's original bet and it pays two to one if it wins.

I'm going to…

…put a two for the pace if the dealer has a 10 point card in the hole and a negative one if the dealer has an ace and a nine which represents that the player lost his insurance bet.

Let's assume six packs of cards, shall we?

Assuming no other information other than the ace up the dealer already has, there are 96 winning cards for the insurance bet, 16 times 6 out of 311 left. There's 311 because a full six-deck shoe is 312 cards and we take one out because of the dealer's ace, and there are 215 cards that will cause the insurance bet to lose.

Let's take the product of the win and the probability.

2 times 96 over 311 is 61.74% and 215 divided by 311 times -1 is -69.13%. In other words, the player can expect to win 61.74% of his bet and lose 69.13% of his bet. We take the sum which is -7.40%. That means that for every dollar the player bets on insurance, he can expect to lose 7.4 cents or 7.4% of whatever his insurance bet is.

7.4% is a pretty high house advantage and consequently, I recommend that you say no to insurance every time. Before someone says in the comments, 'Mike, what if the count is good? What if I'm counting cards?'

Yes. Then, of course, there are exceptions. If you've been counting cards and you know that the remaining cards are very 10 rich, but for the recreational player that's not counting, insurance is a terrible bet and, again, I recommend you decline it every time.

'What about even money?'

You might be asking me. Well, let me explain to you first of all, that the even money offer is the same thing as taking insurance. It's only offered when the player already has a blackjack and the dealer has an ace up.

Let's look…

…at what would happen both ways if the player has a blackjack and takes insurance. If the dealer ends up getting that blackjack, the main bet will push, so it wins nothing, but the insurance but will win one unit because the player bets half a unit on insurance. The insurance but pays two to one on the winning blackjack. One-half times two equals one.

Next…

If the dealer does not get that blackjack, the player's main wager will pay one and a half but he will lose half a unit on the insurance. The combined when between the main wager and the insurance wager is one unit when the dealer does get a blackjack and one unit when the dealer does not get a blackjack.

It doesn't make any difference whether or not the dealer gets a blackjack. If the player has a blackjack and takes insurance, he wins one unit either way and what the dealer is essentially saying is, 'Look, if you take insurance, you're going to win one to one regardless if I have a blackjack. I may as well just pay you now before I even check what I have.”

It sounds attractive but let's do some math and see if you should take it. Let's evaluate the situation where the player has a blackjack, the dealer has an ace up and the player declines insurance. If the dealer has a 10 in the hole, then the player will win nothing because it will be a blackjack against blackjack tie, in other words, a push. If the dealer has anything else in the hole, the player will win his full three to two on his wager or 1.5.

Let's assume:

knowledge of no other cards in the shoe other than what's already on the table. There are 309 cards left out of the 312 card shoe, less than three cards already involved, the player's ace and 10 and the dealers ace.

The probability that the dealer has a 10 in the hole is 95 divided by 309. Like I just said, there's 309 cards left, the shoe started with 96 tens but the player has one of them. The chances that the dealer has an ace to 9 in the hole is 214 divided by 309.

Let's examine what the playe
