History of blackjack D'Alembert is a simple linear system named after the eighteenth-century theorist Jean le Rond d'Alembert. Playing blackjack successfully, using strategies, means being able to figure out the card sum of other players and even the dealer. The Anti-Martingale system requires that you double your bets after a win instead of a loss, the reverse of the Martingale system.
It may not seem right to be taking that card when the strategy says you should but if you remember that the strategies are formed by mathematicians using complex calculations and tested over thousands and thousands of simulated hands.
