Blackjack Doubling Down Strategy Guide

Doubling down is a useful option which allows you to gain more money when you think you have a rather good shot for beating the dealer with hitting for a single last card, but it's not always clear to players when to do so. But with a good blackjack doubling down strategy you'll know when to double and when not to.

While some players rely on their instincts to decide when to double down others would prefer to rely on math and blackjack odds. By relying on math and odds you can be sure that in the long run your doubling down strategy would earn you more money than it would lose. The following options rely on math and blackjack odds so you can be sure to use them without a doubt.

Doubling Down Strategy Options

  1. A hand Value of Hard 11 - It is always advisable to double down when your hand value is 11 since there is a 30.7% chance to hit another 10-value card and to improve your hand to 21, which is an unbeatable hand less the dealer has a blackjack, and in such case it would only result in a push and you would not lose your money.
  2. A hand Value of Soft 11 - Not all casinos would allow you to double on a Soft 11, but if they do then the above strategy is advised.
  3. A hand Value of 10 - As with a hand value of 11, doubling has a high chance for improving your hand to a 20 value hand, this is a good hand in blackjack, but when the dealer's up card is 10, face-card or an Ace then with a hand of 20 you have a fair chance for a push.
  4. A hand Value of Hard 9 - As with a hand of 11 doubling has a high chance for improving your hand to a 19 value hand, still a power full hand, the only deter is when the dealer's up card is 8/9/10/face-card/Ace. This improves the dealer's odds to get a better hand, but still – the correct blackjack doubling down strategy here is to double.
  5. A hand Value of 8 - The correct blackjack doubling down strategy here is not to double. Many are tempted to double with a hand value of 8 hoping to improve it to an 18 value hand, which isn't always the case. With a hand value of 11 you can double, get a 7 card and still have a powerful hand – 18, with a hand value of 8 this is not the case.
  6. A hand Value higher than 11 - It is not advisable to double with a hand value higher then 11, you have a 30.7% chance to bust, with a hand value of 12 you have a 56% chance to bust and the figure keep on rising as the hand's total grows.
  7. A hand Value lower than 8 - You have little chances to improve your current hand into a powerful hand that would beat the dealer, but if you feel that the dealer would bust then, and only then, double down. Such strategy is advised only if you use card counting techniques or you have sufficient experience.

The best way to improve your blackjack doubling down strategy is to practice and test it as much as possible, in order to do so you can play free online blackjack games and you wont risk your money at all.
