The math that keeps you in action long enough for your edge to compound. Unit sizing, Kelly Criterion with real examples, risk-of-ruin tables, and the discipline framework.
The Beginner's Guide to Sports Betting
A plain-English walkthrough of how sports betting actually works — bet types, payout math, realistic expectations, the most common mistakes, and responsible gambling.
Guides
Deeper dives into odds math, pricing concepts, and the research frameworks behind each pillar.
What Is Implied Probability?
Convert American odds to a win percentage, understand what the vig does to implied probability, and use it as the first step in evaluating any bet.
What Is the Vig?
The built-in margin that raises your break-even rate, lowers your expected payout, and compounds silently across every bet. The math, the damage, and what to do about it.
Expected Value in Sports Betting
The core framework for deciding whether a bet is worth making. How to calculate EV, why win rate alone misleads, and what line shopping does to EV without touching your handicap.
Line Shopping
Comparing odds across books to find the best price on the same bet. Why a few cents changes your break-even rate, and how to do it efficiently for spreads, moneylines, and props.
Closing Line Value (CLV)
What CLV measures, how to calculate it, when it is a useful process metric, and when it is overrated — especially for low-liquidity prop markets.
Kelly Criterion
A formula that converts an estimated edge into a bankroll fraction. The math, full vs. fractional Kelly, why probability error is the real risk, and practical guardrails.
Sports Betting Glossary
Odds formats, bet types, bankroll terms, line movement, and betting jargon — defined clearly and grouped by topic.
