If this was the case, the chance of the dealer having a 10-value hole card (and therefore you winning your insurance bet) would be even lower.

This hand is a best case scenario because neither you, nor any other players have 10-value cards in their initial hands. However, the 33 losses at £10-a-time leaves you £10 down overall.Each win pays £20 profit, making a total of £320. On average the £10 insurance bet wins 16 times and loses 33 times.Despite this, your position remains one which is not likely to be possible in the long term.This means 16 of the remaining 49 cards have a value of 10, giving your £10 insurance bet the highest possible chance of winning.

You are playing alone against the dealer in a one-deck game and neither card in your initial hand has a value of 10.The following example shows why, even in a best-case scenario such as the one below, betting blackjack insurance is a losing strategy in the long run. Why insurance should generally be avoided in blackjack Expert card counters can keep track of the amount that are still in the deck and ascertain when there are enough to make insurance the percentage call. You need the dealer to have a 10-value card as his hole card to win your insurance bet. However, probability suggests that insurance is likely to be a losing bet in the long term, unless you are a very capable card counter. Insurance can seem like an attractive option for the player if the dealer’s up-card is an ace, as there is a close to a one-in-three chance their other card has a value of 10.
