How to get the shuttlecock with your badminton racket??

What? Free? I buy 10 at a time. It's difficult to play a match while hiding stolen missiles about your person, (although George Michael managed it). But good luck with that! If you meant hitting it, I usually do OK with a lob shot, but you have to lure them up to the net with far-flung long strong shots first. Then tip it gently over the divider, and be gracious about your victory.
