In tennis, a Chop is a shot that uses extreme underspin to create a low, slicing ball.
The player hits down on the back of the ball with an angled racket. This creates heavy backspin, making the ball dive quickly after bouncing.
Chop shots are usually defensive and can be hit from both forehand and backhand sides. They're often used to counter hard-hitting opponents or handle low balls. Chops can be difficult for opponents to return due to their unusual bounce.
