When playing blackjack, it is important to know when to “double down.” There are a few factors to consider when making this decision: the number of decks in use, the amount of money in the player’s hand, and the dealer’s hole card.
If there are two or more decks in use, doubling down is typically a good idea if the player has at least 21 points (two jacks and a queen). If the player has 16 or less points, it is generally not a good idea to double down.
If the player has only one deck of cards and has at least 21 points, doubling down is generally a good idea.
The dealer’s hole card can also affect whether or not to double down. If the dealer has a ten or an ace showing, it is often better not to double down because this could give the dealer an opportunity to hit on all fours (a bust).
If the dealer has any other card showing, such as a two or three, it is usually a good idea to double down.
