Sharp betting is not picks, it is arithmetic. These are plain-English explainers of the concepts that actually move long-term results, each tied to a free tool you can use right now.
The single number that separates a winning bettor from a losing one over time. →
The whole strategy in one idea: only place bets that pay more than they are worth. →
Backing both sides at prices generous enough to profit no matter who wins. →
One leg from a big payout. Here is the exact math for locking profit instead of sweating it. →
Your preseason longshot made the final. Here is how to turn the ticket into cash before kickoff. →
Site credit is not money until you hedge it. The math that turns a 100 bonus bet into about 66 in cash, guaranteed. →
Bet both sides at different numbers and there is a window where both tickets cash. →
Every parlay is just multiplication. The book's edge multiplies right along with it. →
No US book guarantees best odds. Shopping the line is the do-it-yourself version, and it is worth real money. →
The one metric that predicts whether you will win long term, before the results even arrive. →
When a line moves hard and fast across every book at once, and why the timing is everything. →
When the line moves the opposite way from where the public money is going. →
Quick answers to the definitional questions bettors actually type. Each concept gets the full treatment in the explainers above.
-110 means you risk $110 to win $100. It is the standard price on spreads and totals, and the extra $10 is the book's cut. At -110 you need to win 52.4% of your bets just to break even, which is why finding -105 on the same side matters.
Vig, also called juice or hold, is the bookmaker's built-in margin on every market. Add up the implied probability of every side and the amount over 100% is the vig. A standard -110 / -110 market carries about a 4.76% overround, which is money the book keeps regardless of the result.
A unit is a bettor's standard stake size, usually 1% to 2% of bankroll. Tracking results in units instead of dollars makes records comparable: up 12 units means the same discipline whether your unit is $10 or $500.
A moneyline bet is picking which team wins the game outright, no point spread involved. Favorites carry negative prices like -150 (risk $150 to win $100) and underdogs positive ones like +130 (risk $100 to win $130).
A middle is betting both sides of the same game at different numbers, leaving a gap where both bets can win. Take an over 3.5 at one book and an under 5.5 at another, and a result of 4 or 5 cashes both tickets. Miss the window and you only lose the small combined vig.
CLV measures whether the price you bet beat the market's final price at kickoff. Consistently beating the close is the most reliable sign of a long-term winning bettor, more telling than any short stretch of results.
Draw no bet is a soccer market where your stake is refunded if the match ends in a draw. It pays less than the straight three-way moneyline in exchange for removing the draw risk. You can build the same position yourself by splitting your stake between the moneyline and the draw.
An arbitrage, or arb, is when two books price opposite sides of the same market far enough apart that you can back both and profit no matter the result. It happens when the two best prices imply a combined probability under 100%. Books limit accounts that hammer arbs, so treat them as a bonus, not a business.
Line shopping is checking multiple sportsbooks for the best price before placing a bet. The same side is routinely priced several cents apart between books, and over a season that difference is often the gap between a winning and losing record. It is the one habit this site exists to make effortless.
Implied probability is the win rate a betting price assumes, computed as 1 divided by the decimal odds. A -110 price implies 52.4% and +200 implies 33.3%. Comparing a price's implied probability to your honest estimate of the outcome is how you judge whether a bet is worth making.
