you mean to be able to tap them correct? Racket up and stay near the front line. Look mean to scare your opponent. See some youtube examples there. Good luck!
it's really up to your skill level. if you're good enough to lean forward, toe up against the front line, yet still be able to attack any flicks, that's great. but in reality, how fast you are determines where you stand. the slower your reactions and movement and shot ability under pressure, the further back you stand. sure, if that's the case, you forfeit the net dominance, but if you're not good enough to stand so close, don't. you should be the judge. you don't have to lean forward. you simply need to have it in your mind to attack the serve. sometimes, leaning forward throws away you balance and you can end up playing a shot in an awkward position. but most importantly, is to have your racquet up. not somewhere ridiculous like fully extended into the air, but around or slightly above your head. keep your wrist cocked so as soon as the serve is done, you can push at the shot with out the need to take a big swing first.
Racket foot and body weight 70% leaning forward. Racket a bit higher than the net. Brain thinking about the high serve.
yea, i agree with everyone, I stand 1 or 2 steps back from the front line in doubles. in the center of the box for singles. I can get the flicks if i stand 2 back, jst i stand in middle because high serve is about as common as low serve in singles
