I've always been curious how Federer can hit a good 1hbh using the open stance. I stumbled across some great clips -how Federer hits the 1hbh using an Open stance. Here the two slow motion vids.... http://www.youtube.com/watch?v=tOyoPZUhUTM&feature=channel http://www.youtube.com/watch?v=o6n4domfyA0&feature=channel Notice Federer started his 1hbh prep using the open stance, weight is transferred to his left leg. As he swings to make ball contact, he shifts his right leg across to the front (transferring the weight from left leg to the right while in flight). During the follow thru: his left feet lifts and kicks back - providing balance while he is moving forward (body parallel to the net) to finish off his shot. The left foot also provide a good pivot point (giving Federer solid base to turn for the next shot). Federer uses the same open stance technique when he is returning a serve or when the situation calls for. Hope this helps!
