When i play badminton, i try to "smack" hard to the end of my opponent but doesn't go far. My strength?

is strong but it seem that the shuttlecock only reach middle of court. Is it something wrong with my badminton or simply i took weak? when i compare other players, their strength is abt same as mine but they managed to hit far back. why is that so?|||well there are diffreent types of smashes. For example, there are the deep smash, the mid court smash and the slice smash. The diffrence between these three are simply the angle or contact point. If you hit the birdie more infront, you will get more angle thus deeper. For your example, you are hitting it closer to you therefore in the middle. If you hit it right above you, you will get a deep smash. It is all about the contact point! Good Luck!|||its your form kind sir, you must make a sweeping under hand motion and hit the shuttlecock right on the nose. that will generate a correct floating flight path!
