People have been coming up with clever ways to win at games of chance for as long as gambling has existed. Countless betting strategies have emerged over the years as a result of these efforts, some better known than others. Systems like the Martingale, Labouchere, and Fibonacci attract the most attention, and no wonder. They have been around for decades, even centuries.
In today’s article, we are going to discuss a less popular system known as the 2-1-2. It borrows its name from one of the area codes for Manhattan, New York City’s most densely populated borough, and is intended for gamblers who seek to exploit streaks of successive wins. Without further ado, let us get straight into how the 2-1-2 system works.
Impact on Expected Return in Common Casino Games
The main idea behind the 2-1-2 system is supposedly to help you win more money during solid winning streaks and cut down your losses during choppier sessions. But does this strategy help you win more at gambling and can it improve your odds of beating the casino?
Gambling expert Michael Shackleford addressed these questions by analyzing the implementation of the system in several popular casino games like baccarat, roulette, and craps.
The analysis involves a hypothetical (and highly unlikely) winning streak capped at twenty one successful rounds. The probability of this occurring in baccarat is 1 in 2.8 million with wagers on the Player side.
Mr. Shackleford first calculated the average losses per session a system player can anticipate, along with the average number of wagers made per session. He then determined the theoretical expected return each casino game yielded with the 2-1-2 strategy in place.
