What is Square (square money)?
The recreational or public bettor — or the action that comes from them — typically biased toward favorites, overs and household names.
Also known as: public money
Square money is predictable: heavy on the favorite, heavy on the over, heavy on the popular team. Sportsbooks shade lines toward where the public will bet because that is the side they can afford to take more action on. Going against the public is not automatically +EV, but combined with model edge or sharp action, it often is.
