In the mid-1960s, a group, or an individual, came up with a strategy to give a blackjack player the advantage over the casino, known as Oscar’s Grind blackjack strategy. The strategy is a positive progression system that can be used to increase a player’s chance of beating the casino in blackjack. The strategy was created originally for craps but was later applied to blackjack.

It is important for players to understand that the Oscar’s grind system is not a get rich quick guide. Instead, it demands patience, with an aim to make a profit off of one unit.

Different Kinds of Blackjack Betting Systems

In online blackjack, there are two kinds of betting systems, negative and positive progressions.

Negative Progressions

Negative progression means that players raise their wagers after they have undergone a loss. This is not advised as a series of loses can wipe your bankroll out faster.

Positive Progressions

In positive progressions the general theory is that players raise their betting amounts after a win, meaning that a player’s raised bets are funded by money that they have won.
