The top betting systems for blackjack are the negative progression systems. D’Alembert blackjack strategy is one of the top progression betting strategies and one of the lower-risk ones. D’Alembert uses a system of changing your bets based on wins and losses. Players, therefore, adapt to the blackjack game flow and adjust their bets accordingly as we are about to show you.

Let us take a look at the D’Alembert blackjack betting system, how it works and whether it is worth it. Moreover, let us analyze its advantages and disadvantages when it comes to playing blackjack for real money.

D’Alembert Betting Strategy Explained

The originator of this system is the French mathematician Jean le Rond D’Alembert that studies the theories of long-term balance. As such the D’Alembert blackjack betting system deals with the ratio of wins and losses and how players should alter their bets based on their current outcome. It is therefore a progressive betting system and it works as follows.

The player begins betting with one unit that can be any value that the player decides based on their budget. When the player loses they should increase their bet by one unit as their chances of a victory are higher. When the player wins they should decrease their bet by one unit as their chances of a loss are higher. The system is quite simple to follow and is designed to mitigate losses and always procure a positive end to a blackjack session.

It should be noted that the D’Alembert betting system is best used with a game fully based on chance. Therefore, players should always use the most optimal blackjack action by utilizing the blackjack strategy chart which minimizes the house edge. This way, mistakes due to player decisions are eliminated when it comes to beginner blackjack players.

Furthermore, while following this optimal style of play, when the player wins their chances of losing are increased and vice versa. This is why the D’Alembert system decreases the bet by one unit on a win and increases it on a loss.

Advantages of the D’Alembert

The stability of the D’Alembert provides the player with low variance and a consistent blackjack gaming session. The strategy allows the player to reduce their losses as the player is always in charge of their bankroll and is constantly modifying it to make up for winning and losing.

Additionally, through thorough testing, D’Alembert has showcased the ability to win at least one unit after a long session. This is complemented by the fact that you can lose the majority of the time and still come out with at least one unit of profit. It is possible to get a streak of losses in a row and still come out on top with a few well-placed wins.

Finally, when it comes to losing, the losses are gradual and not rapid. Remember that after each win you are reducing your betting amount and thus lessening the blow to your bankroll when you eventually lose.

Disadvantages of the D’Alembert

The main issue with the D’Alembert blackjack betting strategy is the potentially high investment on a losing streak. When playing blackjack, you are sometimes unlucky and end up in a losing streak from which you might have difficulty recovering. This is due to the D’Alembert system increasing your bets on losses. This can cause you to reduce your bets and thus be unable to win your losses back.

Another factor is that a very specific sequence of events needs to take place for higher wins with the D’Alembert. Although to be fair, every progressive betting system has this issue.

Should You Use the D’Alembert Betting Strategy?

Depending on the circumstance, D’Alembert is worth it in more cases than when it is not. It is a stable betting system with a low variance that can help you profit even when the number of losses is greater than your wins. Players should keep in mind that it can also cost you a lot of money during losing streaks as you are constantly increasing your bet.

Generally, it is less risky than the Martingale system we mentioned in the begging. This is because the Martingale doubles your bet on losses while the D’Alembert simply increases it by one unit. Therefore, the D’Alembert can be sustained for longer and does not tend to go to extremes, both good and bad. One thing you can do though is to set a stake limit for yourself. This limit is where you will stop betting during a prolonged losing streak.

Overall, the D’Alembert blackjack betting strategy is a worthwhile system to try. It is much less risky than other betting systems but it also offers lower payouts. That being said, it is a system that offers at least one unit of profit more often than not at the end of a blackjack session. If you like the notion of the D’Alembert betting system, but also want to try out the alternatives, the Martingale and the Fibonacci blackjack strategies are the most similar.
