Watching the US Open to learn strategy is a very eye opening experience. I notice that some of these players will vary where they stand when executing a serve. What are they after? Anyone know? Usually when I serve it is typically within a foot from the T. Some of these guys will move around a lot and I mean like sometimes standing 3-5 feet from the T when serving. What is the strategy here? I am thinking that it allows them to go out wide while passing over a lower part of the net, but this is just an uneducated assumption. Also, the further from the T you move, doesn't this kill the ability for the down the line bomb? (if so) Why surrender that weapon/option?
