The slow drop shot is also known as the “chop” from the baseline. This is an important still that you need to learn to let your opponent have a sharp lunge towards the shuttle. Might even be a winning shot if you opponent is not alert with where you going to hit the shuttle.
The striking point is same as the clear. Turn the face of the racket slightly and gently send the shuttlecock over the net into the front part of the opponent’s half of the court.
