=> my real question = does the "jump" pertains to after service only or during the rally or return of serve also?
Reasonable people can disagree about this.
Serve and receive are pretty clear. If you stand "pro-style" at the side of the table you have to jump to square up and get behind the table. If you serve bh from behind the table it's a lot easier. On receive you start in ready position and may be able to step in with one foot and back out, if the ball isn't very short to your FH course. So far so simple.
In the rally I think it's almost always better to move with both feet off the ground at once. Maybe the exception is when you only need a small reach to FH, and you step over with your right foot then immediately bring it back after your shot. But any other time it will change your balance and height unless you move both feet. That may be fine for one shot, but you will lose time getting back in position for the next ball, and very soon you can't play on the table. This is my experience. YMMV
=> der and i have been working on my effective strike zone and i am discovering sometimes taking a step closer with my left foot helps with BH loop quality yet you pointed out above "Thinking in terms of steps is possibly unhelpful. Steps are too slow" ... could you provide further context so i gain a fuller understanding? tks man
If the ball comes directly to your backhand right where you are standing, and the only problem is it doesn't come deep enough to you, then Der's solution is perfect.
Step in, play, step out, ready for another ball. Usually it would be better to also move slightly to the side so you don't have to move your elbow left or right to adjust to the ball. Maybe you have time to do those two steps separately, or sometimes you don't. The further the distance you need to cover the less well steps will work compared to jumps (or hops, whatevs).
The bottom line is any moving to the ball beats not moving. So if a step is enough great. And taking a step in may not be perfect, but it's a lot better than standing and waiting for a ball that won't come out to you.
For now just move your strike zone around as best you can and it will develop as you play progressively higher levels.
=> i've been told there's many ways to hit a shot, win a game or develop my BH blocking a loop, in a way, that frustrates me, a lot, b/c i want to be told what to do, just tell me what to do and i'll go to work ... until a point where i have more confidence and i am more capable of figuring things out for myself, i would understand my own game better then too, just a thot
Well, it's a complicated game. Infinite varieties of serve, four main rubber surfaces that play completely differently, seven or eight major play styles, it goes on and on.
If it helps your mind, you could also think of it as there only being one way to hit any table tennis shot. You always move to the ball and use the same kinetic chain (as der said to wrighty) to touch your paddle to the ball. Some swings are bigger or smaller and faster or slower. The bat angle changes maybe. But it's the exact same basic thing every time. Even on a BH block.
I play better and win more when I think in terms of priorities and not at all about technique. My priority order for every shot goes like this.
Play this ball:
1) on the table
2) with spin
3) and good placement
4) and the right timing (top of the bounce mostly but not always)
5) lowest priority if everything else is perfect, is power.
