What is Sharp (sharp money)?
A professional or professional-quality bettor, or the action that comes from one, typically defined by long-term profit and consistent closing line value.
Sharp money is what books fear and what other bettors track. A sharp's wager carries information. It is a vote that the line is off. Watching sharp action via reverse line moves (the line moves opposite to where the public is betting) is one of the few public-data signals casual bettors can use to identify +EV plays without their own model.
