Ed Thorp is a mathematician, investor, and blackjack player who developed the card counting system known as the “Thorp count”, which is now used even in online pokies real money. He is also the author of the 1964 book Beat the Dealer, credited with popularising the concept of card counting and bringing it to the mainstream.
Thorp’s work on casino blackjack and card counting led to him being banned from many casinos, but he continued to win money playing the game. He is also a successful investor, and his work in hedge fund management and stock market analysis has made him a billionaire.
Who Is Ed Thorp?
Ed Thorp is a maths professor who developed the Kelly criterion, a formula for determining how much of one’s bankroll to wager on a given bet. The Kelly criterion considers both the expected return of the bet and the variance of the returns. He is also a successful hedge fund manager and investor. Thorp was born in 1932 and grew up in California. He attended the University of California, Los Angeles, earning a bachelor’s degree in mathematics. He then earned a PhD in mathematics from New York University.
Thorp began his career as a maths professor at the Massachusetts Institute of Technology. It was there that he developed a casino blackjack card-counting system. He used this system to win money from casinos playing big gambles. Thorp later became a successful hedge fund manager and casino investor. He is now retired and living in Newport Beach, California.
What Is the Kelly Criterion?
The Kelly criterion is a formula used to determine the optimal size of a bet or investment. It takes into account both the potential return and the risk of the investment and provides a way to maximise the expected return while minimising the risk:
- The Kelly criterion is named after John L. Kelly, Jr., who first published it in 1956.
- Kelly was working at Bell Labs at the time, and he developed the formula while trying to find a way to improve the efficiency of communications systems.
- The Kelly criterion has since been applied to a wide variety of situations, including best payout online casino gambling, stock trading, and portfolio management.
Why Is the Kelly Criterion Important?
The Kelly criterion is a money management strategy used to determine the optimal size of a bet or investment. The Kelly criterion considers the potential return and the risk of the investment. It provides a way to balance these two factors to maximise the expected return. The Kelly criterion has been used by successful investors such as Warren Buffett and George Soros and is an effective way to manage money. The Kelly criterion is important because it provides a framework for making investment decisions that consider both the potential return and the risk of the investment.
When using the Kelly criterion, the casino investor first calculates the expected return on the investment. This expected return is then compared to the risk-free rate of return. The difference between these two rates is called the “risk premium”.
The Kelly criterion states that the optimum bet size is the fraction of the current bankroll that maximises the expected return while minimising the risk. This fraction is known as the “Kelly fraction”. For example, suppose a casino investor has a bankroll of $ 100 and is considering two different investments. Investment A has an expected return of 10 % and a risk premium of 5 %, while investment B has an expected return of 15 % and a risk premium of 10 %.
How Does the Kelly Criterion Affect Blackjack?
The Kelly criterion is a tool used to help casino gamblers determine how much to bet on each hand to maximise their expected return. The Kelly criterion considers the odds of winning and losing and the size of the potential payouts to calculate the optimal bet size. While the Kelly criterion can be applied to any gambling game, it is trendy in blackjack. This is because blackjack has a relatively simple structure and the odds of winning or losing are easy to calculate. Additionally, blackjack payouts are usually significantly higher than the wagers, making them an ideal candidate for Kelly betting.
Casino gamblers need to calculate their edge when using the Kelly criterion. Based on the odds and payouts, this is the percentage of hands they are expected to win. For example, if a blackjack player has a 52 % chance of winning and the payout is 3-to-2, their edge is 4 %.
Once the edge is calculated, the Kelly criterion can be used to determine the optimal bet size. This means that the casino blackjack player should bet 66 % of their bankroll on each hand to maximise their expected return and become successful in gambling.
Conclusion
Ed Thorp is a mathematician who has made significant contributions to the fields of statistics and finance. He is also a well-known blackjack player and has written several books on the subject. Thorp’s work has had a major impact on the way that blackjack is played today, and he is considered to be one of the most important figures in the history of the casino game.
Thorp’s work on card counting led to the development of several successful blackjack betting systems, and his book Beat the Dealer popularised the idea of using card counting to gain an advantage over the best online casino. Thorp’s influence can still be seen today in the way that blackjack is played, and his impact on the casino game for real money is likely to be felt for many years to come.
