start doing that against short balls of the opponent like those
if you hit those standing a foot inside the baseline you will create a lot of pressure but still keep the errors down. to hit every ball on the rise like agassi you will need great timing, footwork and conditioning. so don't do it against deep balls. better pick your spots to step in as a rec player.
again I think ferrer is a good example to emulate regarding tactics since he doesn't have those genius tools (fed can ignore all rules of "directionals" and play the oddest low percentage shots (like an inside in shot against a too centered CC shot) but we cannot).
against a deep forcing shot he will move back but as soon anything lands near the service line he will step in.
this is high percentage tennis but still forcing.
this here not so much
