Ever since I started watching badminton I've always been impressed by Lin Dan's "clip" smash. The way he runs round his backhand corner and tap the shuttle down (many of the times despite it being behind him) is just pure awesome. He can do this on the forehand side as well, a jump, then the cross-court "clip", leaving his opponent stranded time and time again. I have yet to see another player display this skill to the degree that Lin Dan does, their taps are like fast drops whereas Lin Dan's are like full-power smashes at times. How does Lin Dan do this? Is it thanks to his unorthodox grip, wrist strength or is it a secret he keeps to himself? What do you think?
