When trying to serve shorter, many players slow down their swing, and when trying to serve long they speed up their swing. Both are mistakes – that's not how you control depth or even ball speed.
"Serving is a violent motion," said two-time (and soon to be five-time) U.S. Men's Champion and future long-time U.S. Men's Team Coach Dan Seemiller at a training camp in the late 1970s – and those words have always stuck with me. If you want to maximize the spin, you maximize the racket speed. (You do this with smooth acceleration, but that's another topic.) If you want to maximize the speed, you also maximize the racket speed (at least as fast as you can make it and keep it on the table).
So how do you adjust the depth? Not by changing the racket speed, which should always reach a maximum around contact, but by three things: the grazing contact; where the ball bounces on your side of the table; and the spin.
If you barely graze the ball, you get two things: more spin and less speed. This means a shorter serve (i.e. one that would likely bounce two or more times on the far side if given the chance). As you sink the ball a bit more into the sponge, you get more speed and so the ball goes deeper. You also lose a little spin – though not as much as you'd think. More of your energy now goes into speed and so you lose some spin, but you also gain some spin from the rebounding of the sponge, since you've sunk the ball slightly into it at an angle.
And so you can control the depth primarily by how much you graze the ball. Want it to go short? Graze it finely (and get more spin as well), and the ball will travel slower, and so land shorter. Want it to go longer? Sink it a bit more into the sponge.
You also control depth by where it bounces on your side of the table. If the first bounce is near the net, you'll tend to get a shorter serve. If it's nearer your own end-line, then the ball has a long way to go to get to the net – 4.5 feet – and so will likely bounce deeper. Most top players like to serve the ball so the first bounce is as close to their own end-line as possible while still barely going short (with the second bounce on the far side, given the chance, right on the end-line or sometimes just a touch past it).
You also control depth with spin – backspin will make it bounce shorter, topspin longer. A good sidespin serve can also make the ball go shorter as it curves the ball sideways, keeping it over the table rather than bouncing out.
You also can keep the ball shorter by serving it low over the net – but that's a given. Always serve low to the net. You also can get a "shorter" serve by serving crosscourt, where you have more table, instead of down the line.
So learn to serve with that "violent" motion, and vary the depth with your contact, first bounce, and spin. It's easy to remember – Contact, Bounce, Spin = CBS! (After practicing your serves, you have my permission to go watch TV.)
Re: May 31, 2016 - How to Cover a Short Ball to the Forehand
Larry,
I would kind of disagree with you on the stepping in as far as you can. In order to step in the farthest (with your foot) you actually need to lean your upper body back to keep your balance. The foot goes well under the table, but your shoulder (and thus your racket) does not move forward that much. I think what you want to do is step as far under the table as you can while still maintaining (or even increasing) the forward lean in you upper body.
I read this "step under as far as you can" idea and tried to follow it. I could never figure out why I had such trouble reaching the short balls until I saw some video of myself. I stepped well under the table, but my head never got over the table. Now I try to lean forward and then step under as far as I can. My foot does not go as far under the table, but now my head is over the table and I have very good reach to get to the short ball.
It is kind of a semantics problem. I am sure if a coach had been watching me he would have corrected what I was doing and I would have quickly gone to "stepping in as far as I could while maintaining the right posture". However having only read "step in as far as possible" I was over-stepping and actually keeping myself from reaching the ball because the upper body leaned back.
I could be well off base, but this is my impression of what happened in my case.

While you do want to step well in to comfortably reach short balls to the forehand, I decided to change "as far in as you can" to "as far in as needed." Hopefully that puts us in agreement!

Am I correct in assuming that you do want to maintain the forward lean and get your head over the table?
I think I remember you writing something about trying to get the head close to the ball when pushing short balls. The point was that helped prevent "reaching" for the ball and over extending the arm. That would apply in this case also, wouldn't it?
Maybe it was not in one of your articles. But the head close to the ball comment was what made me realize how different I looked in my videos from what good players looked like.
Not trying to detract from the main point of your tip. When coaching serve return I find myself telling students to "step in more" over and over. So I do realize the importance of your advice. I just need to follow that advice as well as pass it along.

When forehand flipping, you do want to lean over the table with the head somewhat close to the ball. However, there are some players who flip with their arms straighter, but that leads to less control. (The advantage is the extra reach and more power for flip kills with the extended arm.)
