Recall that negative progression systems, such as Martingale, are based on increasing the bet after a loss. Insurance systems, on the contrary, are based on decreasing the bet after winning.

As you can see, these two approaches do not contradict each other at all, so there are strategies that combine them into one whole. A striking example of this is the D'Alembert system (D'Alembert), known to players in roulette and other casino games for many years.

## How to play the D'Alembert strategy?

The basic idea of this strategy is to consistently change the bet depending on the outcome of the previous draw.

1. If you win, the bet should be decreased,
2. If you lose, you increase it.

As a rule, this system is used by beginners to play the odds on roulette. Usually the game does not start with the minimum bets, which in the process doubled if you lose and halved if you win. However, depending on the game, the amount of bet increase/decrease can vary.

## Pros and cons of the d'Alambre betting system

This approach is believed to minimize losses and provide fairly regular wins, but in practice, be prepared for occasional failures. If the losing streak is too long, you will reach the upper betting limit even sooner than when following the Martingale strategy, because you will not start from the minimum.

This is a great system for an even game, where winning and losing hands alternate evenly.

In this case, you will win by process. If the game will consist of long repetitions, for example, the same color, you can quickly lose your bank.

At the same time, as in any other system, consistency is important in d'Alambert strategy. If after several losses in a row your nerves give up and you go back to the original bet, the whole point of the strategy is lost. So decide for yourself whether this strategy suits you.

## Varieties of the d'Alambera system

There is a methodology that is directly opposite to the D'Alambert strategy - Contra D'Alembert. In it, the bets are increased by one step when winning and decreased by one step when losing. Thus, the game is played until a set amount is reached.

The bets are then returned to the original amount. This system is suitable for those who do not want to significantly raise the stakes when losing.

## Conclusions about the d'Alambert strategy

Finally, let us remind you once again that the fallout of each number on roulette is in no way related to the previous number, so the effectiveness of systems based on this approach is very relative. Moreover, they will never protect you from losing, unless you can use some gap in the rules of the casino.

Popularly about betting systems and the mathematical superiority of the casino over the player is described in an article by a famous math professor.

But in any case, if you regularly gamble, it is necessary to have an idea of the different systems, so that in each individual case to bet systematically, relying not only on fortune.
