How to master the technique of shrinking the cue in billiards, whether to hit the ball with the cue or to take it back quickly?

When a player hits a white ball, whether it is a high ball or a low ball, the ball rolls first and then rotates because of the extension of the pole, which can be seen clearly under high-speed camera. When professional players play the white ball, the white ball stops at the high or low pole and moves forward or backward when they come out, which is why they can get good results with a light blow. At first, it was tumbling. After a certain distance, the effect of high and low bars came out, which is one of the reasons for judging a player's impenetrable strength. Generally speaking, amateurs get instant results with low tricks and high tricks. In fact, the extension of the club is not enough and the strength is not enough. This is effective, but the white ball is difficult to control. In short, remember, the club should be as long as possible, use lever force instead of hand force, and practice more!
