D'Alembert System (cont.)


This isn't a bad system and you may like to give it a shot. It requires a pad and pencil so as to give you an easy way to keep a record of your past bets. There are different theories, or approaches, spun off of this system. You may even come up with a variation of your own.

The first step is to write down a number which will stand for units or dollars. You adjust your bets according to the number of units that remain on your chart. It calls for you to continually cross off numbers as you win and add numbers as you lose, depending on the decision of the previous spin of the wheel. Here again, the outside bets in roulette provide the best use of this system, as they are considered even propositions.

Write the number 1 on a pad. That stands for units. Either the unit is worth $1, $5 or $25. It is up to you. It is dependent upon each person's own bankroll. You pick one of the three classifications of even bets on the roulette layout, perhaps black. For this session you will only play black.

Your first bet is the number shown on the pad: one unit. Red shows and you lose. Write the number 2 next to the 1, and bet two units. Again you lose and now you write the number 3 in the column and bet three units. This time you win. You cross out the 3 with the amount of your next bet being two, an amount one unit lower than what you just won. Your chart looks like this:

1    2     3/

Again you lose. Again write the number 3 on your chart, and bet three units. Black shows. You win three units, and cross off the 3 and bet two units. Again you win. This time cross off the 2 and bet one unit. Your chart now shows:

1    2/    3/     3/

Since the 1 is still showing, you bet one unit. But red shows and you lose. Write the next highest number of units that you bet on the chart, in this case 2, and bet two units. Black shows. You win two units, cross off the 2 from your column, and have only 1 showing. You bet one unit, win, and now cross off the 1 ending this series. Your chart now looks like this:

1/    2/    3/    3/    2/   Complete.

You have a profit of five units. Examine how many wins and losses showed for this series. Black appeared five times, and red four. That means you had an edge of only one hand on the house and ended up with a five unit profit. Luckily, you did not have to place an enor¬mous bet on the table. This was because you never lost most than twice in a row. The theory behind the D'Alembert Method is that when you lose, you only go up one unit. When you win, it is for more units than the previous losing amount. It does not call for a doubling up method, as in the Martingale. If you lose the first six straight in the Martingale, you could be out 63 units. If you lose the first six straight bets in the D'Alembert, you are out 21 units. Of course the Martingale recoups all the losses on one win, as opposed to the D'Alembert, which only returns a win of one unit higher than the previous bet. But here is where the novice does not understand the danger of long losing streaks. A lot of novices believe you 'can't' lose seven or eight even¬money bets in a row, and base that thinking on their reasons for the doubling pattern.
