Points to look for:
- The bat has stopped moving forward soon after making contact. This is because the playing elbow has not moved during contact. Checking the position of the playing elbow against the previous two photographs will confirm this.
- The player has hit the side of the ball more than the top of the ball. Too much topspin on the ball makes it hard to keep the serve short.
- Note the depth of the bounce of the ball on the table. This is typical of a double bounce serve (where the ball will bounce twice on the opponent's side of the table if left untouched). It is very difficult to do a double bounce serve where the bounce on the server's side is close to the endline.
