After a FH down-the-line shot, the player expects the opponent’s response to land approximately 0.5 to 1 meter to the left of the center of the baseline. The angle bisector (yellow) of the best possible responses runs through the two shots (blue). This results in the shorter or longer path to the corresponding position (black circle), which is the most advantageous spot for covering one’s own side of the court.
