Bet smarter, not more.

American odds are just probabilities wearing a costume. -150 means the book thinks it hits about 60% of the time. Learn the conversion and every line on every board becomes readable.

Expected value is the long-run average of a bet — what you'd earn per bet if you could make it a thousand times. A +EV bet can lose tonight and still be the right bet. That distinction is what separates process from luck.

Both sides of a -110/-110 line imply 52.4% each — 104.8% total. That extra 4.8% is the book's fee. You must be better than the vig, not just better than a coin flip, to profit.

The same bet is priced differently at different books. Always taking the best available number is the closest thing to free money in this hobby — worth several percent a year with zero prediction skill required.

Tickets% counts bets; money% counts dollars. When 70% of tickets are on the Over but only 45% of the money, a few big, informed bets are quietly on the Under. That gap is one of the market's most honest signals.

Lines move when money or news arrives. A price shortening fast (steam) means informed money is piling on; a slow drift usually means book rebalancing. Beating the closing line is the classic proof you're betting well.

Decide what your bankroll is, bet 1-2% of it per play, and never change stake size because of how yesterday went. Sizing discipline is the difference between a rough week and a wiped-out account.

A 90% L10 hit rate is 9 games of evidence — enough to notice, not enough to trust blindly. Combine short-term form with larger windows, matchup context, and price before believing a streak.

Across decades of markets, longshots are systematically overpriced and heavy favorites slightly underpriced — because big payouts are fun to bet. Our own research found the same pattern in props. Respect it.

Parlays multiply each leg's vig together, so the house edge grows with every leg you add. They're a legitimate entertainment product — just know the tax rate rises with the payout.

Betting should cost what a hobby costs and feel like a hobby feels. Set limits before you start, never bet money that has a job, and know the warning signs and the help line: 1-800-GAMBLER.
