What Is DAS in Blackjack?
To kick things off simply, DAS is an acronym for Double After Split. It is a rule in both solo and live blackjack that has you doubling down after splitting your hand in two.
DAS is different from standard rules in blackjack. When practiced correctly, it can make all the difference to your game. Rules like DAS give you more options, instead of limiting you like the NDAS rule might. You should always keep this rule in mind when choosing your blackjack table as its availability will affect the house edge that works against you in the game.
When you split a hand in blackjack, you divide a pair into two separate hands, receiving extra cards per hand. DAS lets you double down on one or both of the newly created separate hands. The real skill lies in knowing when to use DAS.
Before using DAS, you should take note of whether the dealer’s up card is weak (a low card). If it is and you have a strong hand (for example, double 10s), doubling down on both hands could potentially increase your payout. When the dealer has a strong card (10, J, Q or K) and you have a weak hand after splitting, it’s probably best to avoid doubling down and focus on hitting instead.
The importance of DAS in blackjack strategy is that it provides you with the opportunity to turn a losing hand into a winning one and/or it could potentially increase your winnings - but there's always risk involved.
DAS Rule Implementation in Gameplay
DAS provides you with options after splitting your hand. If you land a strong hand, doubling down can potentially increase your payout or make up for any losses you would have previously incurred. So, it gives you the chance to turn a weak hand into a strong one. You're most likely to consider following the rule when the dealer’s up card is weak as it gives you a better chance of sealing a win.
Most single-deck blackjack games follow the H17 rule which has the dealer hit on a Soft 17. A Soft 17 is a hand totaling 17 that includes an ace, and the ace is valued as 11. Sometimes you’ll find games that offer DAS and H17, making the game almost even against the house. The idea is that when used wisely, it can give you the edge over the casino.
When playing a two-deck game, it's worth choosing a table that offers the DAS rule. In a situation where the dealer hits a Soft 17 instead of standing, it might be a good time to try DAS. If a two-deck game offers the H17 rule minus the DAS, steer clear.
DAS is ideally used when the dealer’s upcard is weak. In this instance, your chances of scoring higher than the dealer are increased since there's a better chance of the dealer having an overall weaker hand. If the dealer’s up card is strong, it is better to stay put and hit instead. The game becomes more volatile when there are multiple strategic options to consider and you’re exposed to higher stakes, which is often the case when DAS is available.
When adopting strategies in play, it’s important to understand the influence they can have on your bankroll. Remember that splitting and doubling down are actions that both require additional bets. That’s why effective money management is important here, as it helps you protect your bankroll while you enjoy the game to its full potential. It’s also important to note that there is a time and a place to play the DAS rule, and good observation skills and practice allow for an informed decision.
Advantages of the DAS Rule
- Increased opportunities when doubling down after a split if the dealer’s hand is weak.
- Enhanced strategic options.
Disadvantages of the DAS Rule
- Potential risk of higher losses if effective money management isn’t in place, since DAS makes the game more volatile.
