This is indeed feasible in theory. If you have experienced a pot of downspin practice, you should have this experience. We often have the following stages for the level of backspin. The goal at the beginning is to turn the ball. The evaluation index can be that the opposite person uses the ball to receive the serve, and then examine the frequency of the ball to the net. Later, the goal will be higher, that is, the ball cannot be released, and the evaluation index, that is, the second jump is still in the table. Then, you will require the ball to be served very low, at least not to allow the opponent to be able to twist and pull on the first board. The above are all servings that are practiced for actual skills and tactics. When these are played proficiently, you will want to show off your skills a little more. For example, if the pursuit of more extreme is not released, the indicator is that you practice a bowl of serve, and finally the net on the opposite side of the table is full of ping-pong balls. To be more extreme, you can control that during the training process, each serve will bounce back to your own table quickly after the first jump on the opposite table. I have also heard of the more amazing thing, which is that every serve is flared…Ok, then why no one does this in the actual game. I have seen that the main answer has already said that, in fact, it is difficult to control the height of the arc with such a serve. At a certain level, such a serve is a death-hunting. Of course, if the opponent’s level is far from yours, you can indeed serve this way during the game, but such serve is not the reason you won. Then let’s talk about a practical problem. When it comes to the game, it is very good to be able to achieve half the stability of the training level on the service level. For example, as Ma Lin, as the best pen-hold shot player who can serve the backspin in the ball without forwarding (there are a lot of video materials of Ma Lin’s serve on the Internet), when it comes to the real key game, his hands are also trembling. If you are interested, you can take a look at the second half of the final round of the 1999 World Table Tennis Championships men’s singles final. Ma Lin made almost every serve… Then Liu Guoliang played and passively defended herself. Although this may also be a tactic, the defense was broken in the end, and the last ball is typical.
