Kelly Strategy

Kelly Strategy, also Kelly Criterion, was conceived and propounded by John Larry Kelly Jr. in the year 1956. Apart from the fact that it was developed by a genius, one distinguishing attribute of excellence that set this staking strategy apart from other sports betting and staking strategies out there is its incredible hybrid nature.

When one staking strategy is drawing strength from what contents and elements that power three other staking formula, definitely its formula has to be a whole lot thicker and potent in bringing about significance winning experience and creating value for itself in betting and gambling space.

How Kelly Strategy was conceived

Another way we can understand the potency of Kelly Criterion is by looking back to its incidents surrounding its inception – the notion that its founder had in mind that eventually led to its creation. When John finally came up with Kelly Criterion in 1956, it was a manifestation of a fruitful and productive effort that he had embarked on. His goal was to devise a strategy, an initiative, a formula that can be used and applied to investment with the sole aim of maximizing its long-term growth rate. He finally achieved this goal in 1956 when he came up with the Kelly Criterion. Given how powerful the formula has proven, its application extended rapidly far beyond the whims of investment and found its rightful place in the world of betting and gambling.

How Kelly Criterion works exactly

In its quest of taking good care of your bankroll on your behalf and making your more money by winning more of your sports bet, the Kelly strategy takes a holistic approach to management. The strategy makes judicious use of three very important variables to achieve optimal health of your bankroll. These three variables include:

  1. Current bankroll size: That is, your current betting budget.
  2. Bet odds that are available.
  3. Edge that bettors think are available to them in determining the optimal size of their bets.

This is how it works. The logic here is that Kelly Criterion posits that your stake should be larger and bigger for sports bets in there is a reasonable degree of significant edge. Conversely, it implies that for a sports bet that you don’t think you actually have a significant edge on, then it only makes sense that your stake be lower.

The Kelly Criterion Formula

The Kelly Criterion formula makes use of two major variables. Well, they are actually two major outcomes. The first outcome it uses is that it’s either a bettor loses all his stake. The second outcome is that bettor’s stake and profit come back to him if he wins. Before we bring up the formula, you should be aware that there are different variations of Kelly strategy formula today due to differing circumstances. However, you need not worry much about the variations. This is because there are enough Kelly calculators on the Internet that take good care of you on this front.

Now, the Kelly formula looks something like this:

Stake=(((Decimal Odds×Percentage Chance of Winning)-1))/((Decimal Odds-1))×100

Stake: This will be the optimal and desirable size you want you stake amount to be.

Decimal Odds: The bet odds that your bookmaker offers, an example is 3.0.

Percentage Chance of Winning: It’s simply the estimated probability of you winning your bet.

Let’s use a good example to illustrate:

Let’s say for example that you are a big fan of the English Premiership and you decide to take bet odds offered by your bookmaker for Tottenham to win a match with decimal odds of 2.0 and a winning chance of 53%. Now, let’s assume that your bankroll is $500, using the Kelly Criterion calculator, here is what you get:

How Kelly Criterion protect his own

One interesting thing about Kelly Criterion is how it embeds notes of warning in its own doctrine. For example, its logic and formula clearly point out that there may be situations and circumstances where bettors really have no edge, that is, zero edge. This usually happens when the probability offered by your bookmaker is the same as yours. On such occasions, the note of warning is to avoid betting.

There may be another scenario that is not even zero edge. In these circumstances, bettors may find themselves a negative edge. Negative edge simply means that the probability that your bookmaker offers for a sports event outcome is higher than your own probability for the same outcome. In such circumstances, Kelly preaches that bettors can either completely avoid the bet, or those with a relatively high level of risk threshold can lay such bets.

One last important detail to mention is the question of whether this particular variable staking type in context is the most appropriate or right for you. To be frank, that is completely a question of personal preference and compatibility. Without mincing words, we’ve identified and explained the numerous advantages and strengths of Kelly staking plan and what makes it soar higher in the world of betting and gambling. However, whether it’s the right staking plan choice for you will depend on your risk threshold, your bankroll size, your betting goals, and your betting habit.
