In blackjack, a player doubles if they have two cards of the same rank, and they would otherwise lose. The rationale for doubling is that it increases the chances of being dealt a good hand.
Doubling also allows a player to take more risks, since they are less likely to lose everything if they get unlucky. So why would someone want to double in blackjack? There are a few reasons. .
Firstly, doubling provides an opportunity for a player to increase their chances of hitting a Royal Flush. Royal Flushes are one of the most common hands in blackjack, and so doubling can increase your chances of getting one by a significant margin.
Secondly, doubling also increases the chances of getting a Four-of-a-kind or better. Four-of-a-kind hands are not as common as Royal Flushes, but they can still be valuable and so doubling can make them even moreso.
Finally, doubling also gives players the opportunity to take advantage of split hands. In split hands, each player gets two cards. If either card is another player’s card (e.g., if you get an Ace and another player gets a Two), you automatically lose the hand.
But if both cards are your own cards (e.g., if you get an Ace and a Two),you win the hand with a two-card total greater than their one card total. So by doubling in split hands, you can make sure that you always come out ahead regardless of what happens with the other players’ cards. All things considered, these are all good reasons to double in blackjack!.
