D'Alembert strategy

D'Alembert strategy D'Alembert's economic strategy was invented in the 18th century by the French mathematician and physicist Jean Baptiste Le Ron D'Alembert. This strategy resembles the famous Martingale system, here you also need to place bets on equal chances and, if you lose, increase the bet. But unlike Martingale, in the D'Alembert strategy, the increase in the rate is not doubled, but by one unit.

Let's look at an example to understand the strategy. We bet $ 1 on red, black came up (we lost), so then we bet again on red, but already $ 2. Black comes up again, the next bet will be $ 3, and black comes up again. Then we bet 4 dollars, here we are lucky and red falls out - we won, on the next step we bet 3 dollars, i.e. the previous bet minus one chip (one). If there are winnings during the next spins, then it is also necessary to decrease by one unit, and in case of losses, increase by one.

The essence of D'Alembert's strategy is to get a win with a big bet and a loss with a smaller one. The advantage of this strategy over Martigale is the economy in relation to the deposit. But it can still require a large deposit from the player, because there is a constant increase in rates.
