Sharp Betting Concepts — Key Questions Answered
What is sharp money?
Bets from professional, winning bettors. Sportsbooks move their lines in response to sharp money because it signals the current price is mispriced.
What is reverse line movement?
When the betting line moves opposite to where most of the public money is, signaling that sharp money is on the less popular side strongly enough to override the public tickets.
What's the most common way to de-vig odds?
The multiplicative (proportional) method: convert each side to implied probability, add them, and divide each by the total so they sum to 100%.
Why did my sportsbook limit my account?
Retail books limit bettors they judge to be long-term winners - often those who bet soft lines fast, only take value prices, or focus on promos and arbs. It's a business decision to cut unprofitable customers.
Why are parlays considered bad bets?
Because the sportsbook's margin compounds across every leg. A random multi-leg parlay of favorites can carry a hold of 20-30%, far worse than a single bet.
