Can you smash a serve that you are receiving from the opposite team? Also, can you leave your service court when you are the receiver in order to play the shuttle?
Smashing your opposition's serve depends on the serve itself. Its a high one in mid court, why not? I believe, your not allowed to move until the shuttle is put into play. That means you can't leave your court before the shuttle has been served. That also includes making and noises or sounds that make distract your opponent.
I've seen someone constantly moving when they are getting ready to serve. When I say move, it's like "shaking" or dancing moving. Can he do that? Where does it say in the IBF rulebook? It's like a moving distraction to the serving side.
as long as both your feet are planted to the ground, i believe your body can move as much as you want up to the point it is not distracting your opponent.
I am not too sure but is it true ur arm has to be above or below ur waist when u serve????? It's either one, I am not too sure.
