Sports betting, plain English

Read the math sharps actually use. Twelve evergreen explainers, no fluff.

Moneyline is the cleanest bet on the board. Pick the winner straight up. The math under the hood matters more than people think.

A unit is how sharp bettors talk about size without revealing their bankroll. Standard unit = 1% of your roll. Here's why.

Positive expected value (+EV) is the only thing that wins long-term in sports betting. Math, not feelings.

Odds tell you two things at once: how much you risk to win, and the implied probability. Here's how to read them without confusion.

Kelly Criterion sizes bets to maximize log-bankroll growth. Used full, it's reckless. Used fractional, it's the right answer.

Teasers move the line in your favor across multiple games. Sometimes a sharp play, mostly a tax on bettors who don't know the math.

Same bet, two books, different prices. Always take the better number. The compounded edge over a season is bigger than people think.

Implied probability tells you what win rate the sportsbook thinks each side has. De-vig it, and you have the closest thing to true probability.

Steam = sharp money hitting a number across multiple books at once. Sometimes you follow it, sometimes you fade. Knowing which is the edge.

Sharps win on price. Squares lose on size. The two edges are about as different as it gets in sports betting.

Hold is the cost of doing business with a sportsbook. The lower the hold, the more of your edge survives the bet.

Sharps don't find edges by watching games. They find edges by reading prices. Here's the playbook.

Reading is half. Tailing real plays is the other half.
