Betting Basics

The single number that decides whether a bet is worth making, with worked examples.

Why the price you beat matters more than this week's win-loss record.

From a win probability to a break-even price, and the edge threshold that flags a value play.

The hidden tax in every line, why -110 already favors the book, and the break-even you actually need.

Why a 40% bettor can crush a 60% bettor, and why price beats record every time.

Why pros talk in units, how fractional Kelly sizes a bet, and the one thing you fully control.

Why a real edge still has losing months, and how much swing is normal over 100 bets.

When a bet ties the line, why half-points matter, and how pushes change EV.

How parlays multiply the house edge, and why every play on the board is a straight bet.
