There are many advantages to betting on sports, but one of the most effective is tracking line movement. This phenomenon occurs when the masses are on one side of a game and the odds move against it. This can indicate that sharp bettors are lining up on the opposite side. To bet on a game with this kind of line movement, you must know the key aspects of the game before you place your bet. You must also be aware of the different types of sports betting lines available, including in-game events.
