Hand going to Right Twice
is a reason along with still head that this slice serve works so well. One can mentally be firing the shoulder rotors forward while the racket still is winding back. And rotors are more effective when upper arm is parallel to court with whole arm right-angled. The mechanical advantage is greater than if both halves of the arm started out squeezed together. Also, from the right angle, your arm has half the distance to go to get itself flung passively straight. At that point the fact that the elbow also is rising does not matter. The firing rotors with first movement forward immediately centrifugate hand to right. In a thousand-frames-per-second filmstrip of this very fast, continuous throw seen midway we could say, "Oh, my arm is straight. Now it's time to pronate."
Despite what anyone says, however, and despite the semantic distinction that says that word ("pronate") applies only to muscular forearm twist, muscular shoulder twist contributes too same as in a Federer-type forehand. And so, as in that shot, you have a choice. You can push the racket head left from your hand, abandoning the precision you so carefully built up. Or you can go with the flow and pull the hand away from the strings. This and only this won't mess with the straightness of their flight.
I sing BOTH of Ralston type slice serve and Federer type topspin forehand. In the serve due to spaghetti arm the hand flies toward opposite fence but also to the right. In the forehand due to a solid connection between arm and body the hand flies toward opposite fence but also to the right.
In the serve the hand then gets out of the way of the slicing strings by shifting to right again. In the forehand the racket butt never stops or slows down since it is firmly connected to smooth body rotation. It is rather the racket tip that seems to get stuck in a puddle of mud as the racket butt, uncaring, is unaffected except to spear to right more.
In the serve the combination of all motions brings racket up then down low and even back toward body preceding an easy, floppy bend of arm to bring racket up to final position. In the forehand the racket butt suddenly drives left to get out of the way of the shearing strings and to initiate big sideways recovery movement toward center including the human head.
