This means that the player can place a bet, no more than half the original bet, in front of the betting box in the section marked Insurance. If the dealer gets Blackjack, the Insurance bet paid off at 2 to 1 (which covers the original bet). If the dealer does not get Blackjack the Insurance bet is lost and the game continues as normal.

Real-world casinos will often allow you to use a blackjack strategy chart, and some will sell them. If you're playing blackjack online, Outplayed's Blackjack Strategy Calculator, which incorporates the Basic Strategy, is a fantastic tool. It tells you exactly how you should play, no matter what cards are dealt, to give you the highest possible Return To Player. To use it, you just need to enter the dealer's upcard and the two cards you're initially dealt. The calculator will let you know whether you should hit, stand, double, split or surrender.
