Understanding Your Bankroll
Your bankroll is the total amount of money you are willing to risk on sports betting. It’s essential to have a clear picture of this amount, as it helps determine your bet sizes. For example, if your bankroll is $27,000, you might decide to keep it at that figure until you surpass $28,000. This practice of adjusting your bankroll helps in maintaining discipline and avoiding unnecessary risks.
The Kelly Criterion Explained
The Kelly Criterion is a formula used to determine the optimal bet size based on the odds of winning. It originated from John Kelly’s work at Bell Labs, intended for analyzing long-distance telephone signals. In sports betting, it serves as a risk management tool, helping you decide how much of your bankroll to wager based on your estimated probability of winning.
However, a common misconception is that the Kelly Criterion is infallible. It’s crucial to understand that your probability estimates significantly impact the effectiveness of this tool. If your estimates are off, the recommended bet size may not be beneficial. For example, if you mistakenly believe a bet has positive expected value (EV) when it does not, the Kelly Criterion can lead you astray.
Key Considerations for Bet Sizing
When determining your bet size, consider the following:
- Your Comfort Level: Understand how much you’re comfortable losing on any given day. If losing $100 causes distress, it’s better to set your limit lower.
- Market Analysis: Always analyze the market carefully. Use sharp books as a reference and be wary of betting too heavily on underdogs without proper justification.
- Rounding Your Bets: To avoid appearing as a sharp bettor, round your bet sizes to $5 or $10. This practice can help maintain your longevity in betting.

De-vigging Methodology
De-vigging is a methodology used to assess the potential outcomes of a betting scenario. The key takeaway here is to use the worst-case scenario unless you have better information. This approach helps manage the inherent uncertainty in sports betting, particularly with larger underdogs or favorites.
For instance, if you’re considering a bet on a team with odds of +135, you might initially think of placing a larger bet based on the expected value. However, if the market signals indicate uncertainty, it’s wise to reduce your bet size, even if the odds seem favorable.
Practical Example
Let’s explore a practical example. Suppose you’re looking at a betting opportunity for the Minnesota Twins against the Detroit Tigers. If the Kelly Criterion suggests a bet size of $140 based on a 4.58% EV, but you feel uneasy about the randomness of the first inning, you might decide to bet $100 instead. This conservative approach allows you to manage risk while still participating in the bet.
Final Thoughts
In conclusion, the key rules for effective bet sizing are:
- When in doubt, bet less.
- Always analyze the market and understand your comfort level with potential losses.
- Use the Kelly Criterion as a guideline, but do not rely on it blindly.
By managing your bankroll effectively and being mindful of your betting strategies, you can enhance your chances of long-term success in sports betting.
