Practice matches are exactly that - practice. That means you should play them so as to maximize how much practice you get from them - meaning maximizing your improvement from them. This means several things. 

1. Play practice matches as hard as you play tournament matches. If you don't play them seriously, then you won't be able to practice the mental or physical skills you'll need when you play tournament matches. 
2. Play them for practice. This means playing some matches exactly as you'd play them in tournaments, so as to maximize your practice for how you should play in a tournament. But you should also use them to practice the techniques you need to develop. For example, if you have trouble counterlooping, and so avoid counterlooping in practice matches, then you'll never develop your counterlooping skills in a match situation. This is your chance to practice the style you are trying to develop.
3. Don't worry about winning or losing; worry about how you played the game. Did you maximize your practice (good) or maximize your chances of winning (sometimes good)?

To give an example of the difference between a practice match and a tournament match, I'll use a player I used to play named Paul. I was rated a little higher than him, but he had one skill that he did a lot better than me at the time - he was a great counterlooper. So, when we played practice matches, we had lots of counterlooping duels. My counterlooping got better and better . . . but he always won, since we were playing his game. Then we played in a tournament - and this time I stayed mostly right at the table, only occasionally counterlooping. I won easily. Result of all this? My counterlooping game greatly improved, and I not only held my own when I did counterloop with Paul, but it was much better against others as well.

So, next time you play a practice match, think about what type of practice you need and what type of game you are trying to develop, and go to it!!!

One of the biggest differences between forehand and backhand looping is that, for the forehand, the body isn't in the way. This means it's relatively easy to take the ball early, middle, or late in your hitting zone. This makes timing a lot easier.

On the backhand, the body is more in the way, and so you can't adjust the contact point as easily. This means that if you are rushed, you can't that easily just take the ball late. Result? Many players get jammed on the backhand, perhaps by a quick, deep push, and so rush their backswings. Result? Lots of erratic misses.

Early racket preparation is key to the backhand loop. If you hold your racket too high, you won't have time to bring it down into position. If you stand too jammed to the table you also won't have time. Instead, find the perfect ready position for yourself, where you hold the racket low enough so you don't have to rush, and not so close to the table that you get jammed. (Arm's length is usually about right.) You should be able to bring the racket down and back in a smooth motion, and then whip it through the ball, giving the ball an arcing topspin - just like the pros. At the back of the backswing, the racket should actually come to a brief stop as the rest of the arm begins its forward motion (with the arm and elbow pulling), leading to that whiplike motion as you put the racket through the ball, almost like throwing a frisbee in a slightly upward direction. If you don't feel that slight hesitation as your racket reaches the back of its swing, then you are rushing your backswing.

Some of you don't have a backhand loop. Then, may I suggest developing one?

Note that everything here should also be hints on the reverse - how to play a player with a good backhand loop. In particular, this means rushing him with quick, deep pushes, and bringing him in with short serves and pushes and then jamming him with deep pushes.

There are so many snap decisions a player has to make while playing that it's mind-boggling that players often increase the mind-load by adding unnecessary decisions. In table tennis, there is never a decision on whether you have to move; you always move - or more specifically, you always assume you have to move. Maybe once in a hundred shots you might not have to actually move, in which case you prepare to move and simply don't. The huge bulk of the time you will move, even if it is one inch, if you want to play your best shots instead of awkwardly adjusting while reaching.

So, for now on, ban any thinking about whether you have to move. The only decision is in what direction and how far. As the opponent is hitting his shot, flex your knees slightly, perhaps even do a tiny bounce, and finish set to move in either direction as the opponent is hitting his shot. (Watch video of top players to see how they do this - don't watch the ball, focus on one player, and for this, just watch his feet.)

Remember, in table tennis, you aren't an oak tree; you are a squirrel scampering about the court!

Beginners play to the middle forehand and middle backhand. Intermediate players play to the corners. Advanced players play the wide corners and the middle. Which are you?

Assuming you want to be an advanced player, you will learn to attack the middle. The middle is not the middle of the table - it's the mid-point between the opponent's backhand and forehand, the transition point where he has to decide whether to play forehand or backhand, and then move to do one or the other. (You usually go there when attacking, but sometimes even a push to the middle is effective.) Covering the middle is generally the most awkward shot in table tennis, where you have to make a snap decision (forehand or backhand?), make an often awkward move to get into position, and then, after hitting the ball, try to get back into position before the opponent exploits the corner you moved away from.

But it's worse than that. If you play the corners, the opponent has only two options - move left or move right. Even in a fast rally, many opponents can cover those shots consistently. If you also play the middle, some think it means the opponent now has three things to cover. WRONG! They now have FOUR things to cover: the two corners, the forehand from the middle, and the backhand from the middle. It doubles the number of shots they have to prepare for. Worse, while going to the forehand or backhand is an easy decision if the ball is going to the forehand or backhand, covering the middle means that awkward split second while you decide what to do. So the opponent not only has twice as many things to cover, he has to make that split-second decision that he didn't need to make if you only play the corners.

So, do you want to make things easy for your opponent? Keep going for the wide corners, and you'll do well. You'll just never be as good as you could be.

When you decide to go for a shot, or play safe, it usually (not always) means you've thrown tactics and percentages to the wind. If you decide to go for a shot, or play safe, is it because it's the tactical and high-percentage thing to do? Or is it more an emotional thing?

With experience, players successfully play by "feel," where instincts built up over years of play tell them when to "go for" a shot and when to play "safe." But those instincts were built up based on tactical probabilities - over those years they instinctively learned when to do each to maximize their chances of winning. For example, they learn when to be aggressive when returning serve, when to play safe, and when and how to mix it up.

But many players simply make the decision to go for shots or play safe. This often happens when a player is nervous and so can't really think clearly. They may mindlessly go for shots or are afraid to play aggressively and so play safe, even if it's not the smart thing to do. Examine your own game and habits - do you do these things at the right times for the right reasons?

To go back to the title of this tip, you shouldn't think of yourself as "going for a shot" or "playing it safe." If you think you have to go for a shot, that implies it's a difficult shot, which is a quick way to get nervous under pressure and miss. If you think you have to play safe, that implies you aren't able to attack effectively, which is also a quick way to get nervous under pressure, especially if you have to attack on some shots. Instead, just think of it as always trying to do the right shot in any particular situation, and the pressure goes away even as the percentages move in your favor. If that means attacking ("going for shots") or pushing ("playing it safe") then so be it - because, in that situation, it was the right shot.
