In this modern game of topspin, many players battle to see who can get more topspin on the ball, with more speed and more consistency. After all, isn't that what tends to win games? Yet you might want to consider whether you want to join in this escalating topspin battle every single point. Why not throw an occasional changeup at them - a "dummy loop" - and watch them mess up? Go for less spin, and mess up your opponent's consistency!
