Perfected during the 1960s, the loop is essentially the reverse of the chop. The racket is "parallel" to the direction of the stroke ("closed") and the racket thus "grazes" the ball, resulting in a large amount of topspin. A good loop drive will arc quite a bit, and once striking the opponent's side of the table will jump forward, much like a kick serve in tennis. Most professional players nowadays, such as Ding Ning, Timo Boll and Zhang Jike, primarily use loop for offense.
