Contra-d'Alembert
Like Reverse Labouchere, the idea behind Contra-d'Alembert is to reduce the amount risked while allowing profitable runs to rise to great heights. With this strategy, we will increase our wager one level after a win and reduce it one level following a loss.
The only positive aspect to the strategy is that when you hit a prolonged losing streak the size of your wagers is quickly reduced. In this respect, this system can help protect your bankroll.
However, the upside of using any system requiring increasing your wager following wins is limited. Trends of long, uninterrupted winning streaks are fairly rare in gaming and a system relying on piling up a win after consecutive win is not going to win very often.
Here's an example. Your first bet is for one unit. You win and move up to betting two units. With another win, you wager three units and have a loss. You have won two out of three bets and have absolutely nothing to show for it. All of your profit evaporated with that single loss.
If you could always pick your spots, this system would have merit. Of course, if pigs could fly . . . well, you get the idea. It is just about impossible to know in advance when a three-wager consecutive win might occur so that you could jump in with a Contra-d'Alembert. Like so many systems, this one sounds good on paper but is difficult to squeeze profits out of in real-world gaming.
