Kelly Criterion, named after John Kelly, is a popular betting strategy used in various gambling games, including Blackjack. It is a method of determining the optimal amount to bet in a game by considering the player’s edge and the likelihood of winning. The Kelly Criterion is expressed as a percentage of the player’s bankroll and is calculated by multiplying the player’s edge by the odds, then subtracting one. This percentage tells the player how much of their bankroll to bet in the game. Although the Kelly Criterion has some limitations, it has been widely used by gamblers and investors for its effectiveness in maximizing profit over time. (Factual reference: Investopedia)

The Modified Kelly criterion is a betting strategy that is an adjustment of the original Kelly criterion, primarily used in gambling. It suggests a specific percentage of bankroll that should be bet based on the probability of winning and the payoff ratio. The Modified Kelly fraction is obtained by dividing the expected profit by the maximum possible loss and is then adjusted to reduce the risk of ruin. For instance, if a person has a 60% probability of winning a bet with a 2:1 payoff ratio and a bankroll of \$10,000, then the suggested Modified Kelly fraction is 0.25, meaning that the person should only bet 2.5% of their bankroll. The Modified Kelly criterion aims to maximize long-term growth and minimize the risk of ruin.
