Back and lay betting is a unique form of wagering that allows users to bet both for and against an outcome. In traditional betting, you can only back a team or player to win. However, betting exchanges like BetPro introduce the concept of lay betting – where you act as the bookmaker and bet against a particular outcome. For example, you can lay Team A to lose, meaning you profit if any other result happens. This flexibility gives more control to the bettor, especially in live sports where odds fluctuate rapidly. Understanding how to back and lay effectively can lead to better risk management and value betting strategies, especially for traders and experienced punters.
