Someone asked for it some time ago and I got this great pics so here it is (enjoy): Roger begins his forhand motion by changing his grip and taking his racquet back with the help of his left hand. With his eyes locked on the ball, Federer rotates his shoulders and begins his "C" loop backswing. Also notice his knees have bent a little further while remaining in an "open stance" position His racquet is as back as he will take it on this shot. Notice that his backswing is pretty compact compared to Ferrero's. Also his left arm is extending out parallel to the net for balance and full shoulder turn. We saw this same thing with the Ferrero forehand. His shoulders are fully turned on this shot as indicated by the location of his left hand. He begins to bring the racquet down and notice where the racquet head is pointing. Roger typically will "rock" his wrist backwards at this point to allow for greater topspin generation. Notice his head has barely moved and his eyes are always locked on the ball As the ball begins to climb, Federer lowers his racquet even more and bends his knees a bit further. He wants to make sure he gets under that ball pretty good. This is right before contact, his shoulders begin to become squared with the ball, his eyes are DEAD LOCKED at the ball, and the butt of his racquet is facing the ball. This is the contact position. Roger comes slightly off the ground to generate a bit more power. His shoulders and hips are squared at impact and what still amazes me about him is how he keeps those eyes locked on that ball. This is kind of a blurry shot, but there is two important things to note about his stroke here. First, he does not have the traditional over the shoulder follow through (as many pros don't). Roger wraps his racquet around his body with great acceleration. The other thing is that his eyes follow the ball as it comes off his racquet. I've seen many people and pros take their eyes off the ball at this point. This helps him sort of "guide" the ball to where he wants it on the court.
