Learn Doubling Down Blackjack Rules With Game Examples

As mentioned in the previous article about doubling down, when we win against the dealer's point value, our base bet is doubled. The key of doubling down blackjack lies in the timing of choosing to double down. If the timing is incorrect, our losses will also be doubled. Betting with doubling down blackjack at the right moment is crucial to maintaining a steady increase in our Expected Value (EV) and achieving profitability. Therefore, through today's discussion on the doubling rules in Blackjack, I'd like to explore with all the players the timing of doubling down, discussing basic blackjack strategy, and point value calculations. So, let's begin.

Doubling Down Blackjack: Point Value Calculation

In the process of aiming for profitability through Blackjack, learning how to calculate point values is an essential element. This is also the first aspect of the doubling rules in Blackjack that we want to introduce. Familiarizing yourselves with point value calculations will make it easier to proceed with the following basic strategies.

In reality, there are at least five different methods for calculating point values in Blackjack. They all categorize the values of the cards and conduct comprehensive calculations based on the statistics. The goal is to determine how many cards in the remaining deck will be beneficial to your hand, ultimately leading to profitability. Some may wonder why there are so many different methods for calculating point values under the same doubling rules in Blackjack and what the differences are. The discrepancy lies in the assessment of each card. Since point value calculation is approached from a statistical perspective, the optimal solution varies with the remaining number of cards in the deck. Therefore, some players use different point value calculations. Today, we'll introduce the most common and widely used method: the Hi-Lo point value calculation.

Through the table above, we can see that Hi-Lo classifies the cards dealt by the dealer into three point value categories: -1/0/1. 

The calculation method involves summing up these values. For example, if the cards dealt are 4/4/5/2/3/A/10/9/9/Q in sequence, we add their corresponding point values:

1+1+1+1+1+(-1)+(-1)+0+0+(-1) = 2.

The resulting value of 2 indicates that more small cards have been dealt, and there are relatively more big cards remaining, allowing us to increase our base bet.

Doubling Down Blackjack: Basic Strategy

Having covered the point value calculation in the doubling rules of Blackjack, now let's delve into the basic blackjack strategy. This strategy guides us on the optimal actions to take when our hand faces specific dealer upcards. While point value calculation determines whether to increase the base bet, the basic strategy informs us of the best actions to take in the current situation.

Refer to the provided chart, where the left column represents our hand, the top row signifies the dealer's upcard, and the explanations in the bottom right corner denote actions such as "H" for hit, "S" for stand, "D" for double down, "Ds" for doubling down if not possible then stand, "N" for no split, "Y" for split. The recommendation here is to avoid any insurance bets, play with pure base bets, and refrain from surrendering strategies as they can decrease our EV value. These suggestions are derived from optimal solutions calculated through statistical software.

Doubling Down Blackjack: Conclusion

Today, we covered the point value calculation and basic blackjack strategy in the doubling rules of Blackjack, forming an introductory combination for profiting through Blackjack. Blackjack is a game of understanding probabilities. Increasing the base bet when the probability of winning is high is information we can obtain through point value calculation. The basic strategy, on the other hand, allows us to maximize our win rate and profits based on the increased information in each round. The complete doubling rules of Blackjack emerge when these two aspects are combined. There are deeper details in the doubling rules of Blackjack, and we hope you memorize the basic strategy chart we explained today. This knowledge will accelerate your actions in future games. This concludes our sharing for today, and we'll see you next time.
