The D’Alembert betting system is a progressive betting system that has been around for many hundreds of years. It is more than likely that as is the case with all betting systems, this system began to be used almost as soon as people began gambling which was actually thousands of years ago. It was given a name however in the 17th century, and that was the D’Alembert System.
The D’Alembert System of betting is far less severe and aggressive than the Martingale System. It is negative progression betting systems which means that you increase the bet when you lose. Rather than doubling up each time there is a loss however as in the Martingale system, the gambler simply increases the bet by just one unit after a loss and decreases the bet by one unit after a win. The system of progression is extremely gradual and potentially allows the player to remain in the game for longer and be able to accumulate more chips.
The idea was put forward by a 17th century mathematician who believed that by applying the scientific fact that ‘nature seeks equilibrium’ you could beat the casino. The science and mathematics behind the system is that the sum of the differences between the forces acting on a system and the time derivatives of the momentum of the actual system along a virtual displacement consistent with the constraints of the system, is zero.
To put it in terms that we an all understand, if we were to adopt this system our actions would be simple. If you were to place for example a $2 bet and lose, you would increase your bet by one unit making your next bet $3. If your $3 bet then wins, you would decrease your bet by one unit back down to $2.
This D’Alembert System system is about protecting your win and insuring against losses. The gentle progression makes it a popular betting system with novice players. It can only be played with casino games that offer a 50-50 chance for winning which makes games such as Roulette and Baccarat ideal for adopting this strategy. Although these games don’t offer these exact odds however, they are very close indeed. It ensures that you cannot wipe your whole bank roll out in one go and locks in a ‘net win’ even if the next round is lost.
Although this system sounds ideal, there is one glaring hole in it that cannot be overlooked. There is often one fact that tends to be glossed over, and that is that the roulette wheel or baccarat cards have no memory. The outcomes of each round or bet are totally independent from one another and under no influence from any previous activity. This system is based on the idea that if you lose once, your chances of winning increase for the next round and therefore you increase your odds of beating the casino. This is not the case and every time the wheel is spun or a bet is placed, the chances of losing stand at 50% or slightly under. This figure never changes and inevitably the house will always win in the long term. A run of losses that runs into hundreds is possible with or without the system in place. There is still a considerable chance that the bank roll will be wiped out entirely, although by adopting the D’Alembert betting system over something such as the Martingale system it will certainly take longer and you could walk away before seeing this happen.
Many gamblers do adopt this strategy and of course see success on occasion. It is important to remember however that despite possible short term success, this betting system by no means guarantees long term success by removing the edge that the house always holds.
