Blackjack Strategy | When Should I Double Down?

Doubling down is a blackjack strategy that could increase your winnings. It is also a high-risk play. The move can pay handsomely if done right, but a flopped double down can make you lose more chips than when you split. 

Using this play can be risky, so knowing what is at stake, make sure it works in your favor. In short, find the perfect balance between risk and keeping it safe. On this page, you will learn about the best time to double down, the rules, and how to play your blackjack hand afterward. 

What Does Double Down Mean in Blackjack?

In blackjack, the double down move means a player increases their wager to twice the amount placed on the ante bet. It happens in the middle of a hand that is already in play. In return, you get a single card from the dealer.

When Should I Double Down?

The double-down blackjack strategy raises the stakes for you. So, when do you double down in blackjack?

The answer to that is simple. Double down when you have a very strong advantage against the dealer. Here are a few examples.

  1. The Cards in Your Hand Total 11

It is very unlikely that you will bust with a hand that totals 11. Receiving an additional card gets you closer to 21 for the win.

  1. When Holding a Hard 9 or 10

A hard hand has no aces and is another good example of when you can double down in blackjack. Use the strategy only when the dealer shows a low card for higher chances of winning.

  1. When Holding a Soft 16, 17 or 18

A soft hand comprises an ace and another card. With such a hand, doubling down only makes sense if the dealer has a low hand.

What Are the Blackjack Double Down Rules?

Blackjack double-down rules vary depending on the casino. 

  • Signal Your Move – A common rule at brick and mortar casinos is signaling your move to the dealer. You can alert them of your intent to double down by moving chips equal to your ante wager next to your current bet. If that doesn’t work, signal the dealer to give you a single card. Take care not to tamper with the stack of chips already placed on the table. That could be interpreted as meddling with your previous bet.
  • One Card – After you double down, you will only receive one additional card.
  • Match the AnteIf you double down, you must wager the exact amount you placed on your ante bet.
  • Double Down Not Allowed – If you have already hit or taken the third card, you can no longer place the double-down wager.
