Hello! We played some doubles with our new friends this monday and we stumbled upon a disagreement - one of them warned my partner, that her service might not work with other players (would be called a fault, but he didn't mind). He said that she is "dragging" the shuttle a little bit forwards just before hitting it with the racket - to explain it better, in the serve motion she moves the shuttle a little bit more in front of her and they said that it is not allowed to "drag" the shuttle this way. I said that I don't know of any rule that would said that this would be a fault (I know the rules quite well, or at least I hope so), but then again they were ~50yo players and I have been playing only for a year and a half, so how could I know more right? So I wanted to know for sure, because I am quite certain that when I watch pro players serve, they often drag the shuttle this way (for example when they flick serve, they often move the shuttle a little bit upwards during the serve motion). Only way I can think of this being a fault would be if the shuttle was on the string bed all the time during the drag? Like if you literally drag the shuttle with the racket head (but that was not the case, I cannot imagine serving that way - no control) Thanks!
