It’s been a little over 60 years since they figured out the optimal strategy for Blackjack. A group of statisticians wrote a paper in 1956, and that paper’s findings were verified in Edward O. Thorp’s 1962 book Beat the Dealer. Now, millions of Blackjack players around the world are learning these strategies, including the option to double down. This is when you double your wager and receive one single card; if you haven’t gone bust after receiving this card, you stand with whatever you’ve got.

With millions of players DoubleDown Casino is the best free casino where you can enjoy a variety of games including over 30+ free slots, slot tournaments, multi-player poker, video poker, bingo,. Blackjack Double Down Blackjack is one of the casino games with the lowest possible house edge, which can be attributed to its favourable set of rules. One such rule that works to the benefit of players is the double down option. It enables you to increase your initial bet when you find yourself in advantageous situations.

If you’re not familiar with doubling down, or you’re still learning the basic strategy, Single Deck Blackjack is the right game to start with. Bovada just introduced a modern version of this game to go alongside the Classic version; try out the following strategies, and you’ll be one step closer to playing perfect Blackjack. At Bovada, you can double any two cards when you play Single Deck Blackjack, and the Dealer must hit on Soft 17.

What Is Double Down in Blackjack?

You can double down after you’re dealt your two hole cards, which means you have the option to double your bet and receive exactly one more card. Then, if you haven’t gone bust already, the Dealer plays, and the winning hand is declared. If you’re playing at a live casino, take however many chips you need to match your original bet, and place them nearby – but outside the betting box. Then use your index finger to point at the doubled bet. Figuring out how to double down at Bovada is much easier: Just hit the “Double” button. No hand signals required.

Blackjack Double Down Rules

In both Single Deck Blackjack variants at Bovada, you’re allowed to double on any two cards you’re dealt – and you can double down after a split. Some live casinos will not allow you to double after you’ve split your hole cards. You might also find games where you’re allowed to double after receiving a third card or more.
When to Double Down
This is where the rubber hits the road. As always in Blackjack, the correct double down strategy will depend on how many decks are in the shoe, and the specific rules for the game you’re playing. Let’s take a closer look at the Single Deck Blackjack games available at Bovada, and how to double down in these games for maximum value. In both the Classic and New versions, the dealer must hit on soft 17, which caters to the following strategies when you’re dealt the following hole cards:

Hard Hands (No Pair)

If you have 11 in your hand (say, Seven-Four), you should always double, hoping to spike that 10-value card to make 21. Otherwise, follow this guide:

10: Double when Dealer shows a Nine or lower

9: Double when Dealer shows a Six or lower

8: Double when Dealer shows a Five or a Six

Soft Hands

With hands containing an Ace, you’ll occasionally double when the Dealer shows a low card (Six or lower). If you’re holding Ace-Six, always double against a low card. Here are the other times to double:

19: Double when Dealer shows a Six

18: Double when Dealer shows a Three, Four, Five or Six

13, 14, 15, 16: Double when Dealer shows a Four, Five or Six

Pairs

In Single Deck Blackjack games where you’re allowed to double after splitting, like the ones at Bovada, there’s only one pair you should double first: a pair of Fives. This should only be done when the Dealer’s up-card is a Nine or lower, just like you would with any other hand worth 10. If you have a pair of Fours, split instead when the Dealer shows a Four as well as a Five or Six, and hit otherwise.

Simplified Doubling Strategies

The doubling plays listed above are mathematically proven to maximize your return playing Single Deck Blackjack at Bovada. They’re part of what’s known as the basic Blackjack strategy – although that’s a bit of a misnomer. Learning all the subtle differences between these optimal moves can take some time. When you’re just starting out, you might want to consider using a simplified Blackjack strategy that’s easier to remember, so you’ll make fewer mistakes trying to implement it. There will be a few plays that you’ll make sub-optimally with a simplified strategy, but only a few.

Here’s one recommended simplified strategy for doubling down in Single Deck Blackjack:

1. Double with Hard 9 or Soft 16-18 if the Dealer shows a low card (2-6).
2. Double with Hard 10 or 11, unless you have 10 and the Dealer shows a 10 or Ace.
