First, we should be able to grasp the key point of the club (the balance center of the club). Secondly, we must decide the position of the body. Third, we must decide the position of our feet. Fourth, bridges. Grip lever
Before we decide where to hold the club, we must first know the center of gravity (the balance center of the club). Usually, the center of gravity of the club is about 50 cm away from the end of the club. The most suitable grip position is about 10 cm behind the center of gravity. Of course, because the length and thickness of the clubs are different, the center of gravity of the clubs is slightly different, so you must choose the clubs that suit you as soon as possible. When you aim correctly, you must pay attention to the position of your face. The so-called correct position of the face is to always put the center of the face directly above the club, so as to aim correctly. The key point to keep the posture stable is to keep the feet in balance with the center of gravity of the body, and the structure of the left hand should be smoothly placed on the line between the right hand grip and the cue ball. The grip of the club is the basic action to set the correct posture, but the grip method often varies from person to person. The way to hold the club is to hold it gently from directly above the club. When holding the club, the thumb, index finger, middle finger and ring finger lightly hold the club, while the little finger and palm touch the club but don't. If the little finger also holds the rod hard, it is likely that there will be abnormalities in the process of hitting the ball, which will affect the correct hitting. If you can hold the club correctly, then your right hand is almost at right angles, which means that the elbow to wrist must be perpendicular to the club. When we make a beat, we swing our wrists back and forth with our elbows as the center, like the pendulum of a clock. bridge
The action of supporting and stabilizing the club with the left hand is called bridging. If the bridge is unstable, the aiming point and impact force will be abnormal when hitting the ball, and sometimes the phenomenon of sliding bar will appear. Beginners often only focus on hitting the ball and ignore the importance of bridging, so they often make mistakes or even mistakes. Beginners must practice more before trying other bridging methods, and use other bridging methods after fully learning the basic bridging methods. The standard bridging position is about 15 cm away from the cue ball, so we must adjust the bridging shape according to the impact point of the cue ball. Due to the difference of cue ball center, center and center, it is also necessary to change the height of fingers when bridging. Besides the basic bridging methods, there are V-shaped bridging method, buckle bridging method, rubber edge bridging method and fingertip bridging method. We will introduce the essentials of various bridging methods one by one with photos. Fingertip bridging method: when the cue ball is close to the cue ball, the bridging method is the same as V-shaped bridging method, but the finger must be propped up to make the ball cross the cue ball (obstacle ball) and hit the cue ball. Buckle bridge method: wrap the club around with the bent index finger and thumb, open the other three fingers as far as possible, and stick your wrist to the table (you can use the height of the bridge to change the hitting point when aiming). Glue-edge bridging method: put the club between the index finger and the middle finger, close to the table top, and form a bridge between the table edge and the fingers (this method is mostly used when the cue ball is close to the table edge). V-shaped bridge method: thumb up and use it to form a V-shape with the root of the index finger. Except the thumb, the other four fingers are stuck on the table, and the club is placed in the V-shaped groove. Basic theory of billiards 2: the basic action of billiards hitting the ball
When you stand in a good position, the grip posture, the face posture and the bridging method are correct, and the preparatory action before hitting the ball has been basically completed, and then the most important hitting action is followed. You must do this slowly and correctly, so that the club can hit the hitting point of the cue ball you want to hit accurately. The hitting action is the preparation action before you hit the ball correctly. Its main point is to take the bent elbow as the axis and then swing the wrist back and forth like a pendulum. There is no special limit to the number of swings, but you should swing back and forth at the same speed and wait until the force is smooth before hitting the ball, so as to master the rolling of the ball. At this time, the elbow or wrist should not be forced, but should swing in a relaxed and natural state. When you swing the cue ball smoothly, the club head must glance forward from where the cue ball stopped? About 0 cm. This phenomenon is called full push rod. Before the end of your push, be sure to stabilize the bridge and not shake it slightly, which is also the key point to hit the ball correctly. It takes a long time to make the cue ball roll as planned, and even a skilled person can't hit the ball properly every time. This is the difficulty of billiards, and beginners are often attracted by it. Basic theory of billiards 3: the movement and direction of the ball
Beginners can successfully hit the cue ball as long as they can fully learn and experience the basic movements of fancy billiards mentioned above. However, most beginners will flash an idea in their minds, that is, they will ask themselves suspiciously: "Why can't I play the cue ball according to my idea?" But when others hit the ball, it turns very flexibly. Why on earth? "Some people with good skills can easily and happily let the cue ball touch two target balls, or let the cue ball hit and roll back, and shoot down the designated target ball into the designated ball bag. Most novices will envy the master of this technical fantasy. The movement of the sphere is quite complicated, so some people call billiards "brain movement". Before we study which part of the cue ball should be hit to make it rotate at will, we must first understand the motion principle of the ball, and after repeated practice, constantly correct the expected error and actual error, so as to learn the essentials of hitting the ball in trial and error. We will explain the basic impact method and the rotation of the ball below. If you accidentally hit the cue ball, it is impossible to score, and it is not easy to improve your skills. If you want a ball with a diameter of about six centimeters to rotate according to your own meaning after being hit, you must remember the characteristics of these balls. Let the ball have an ever-changing rotation and several important factors in the future: impact point: where should I hit the cue ball? Thickness: When the cue ball touches the target ball, the two sides overlap. Power: the power used to hit the ball. Angle: the incident angle, reflection angle and separation angle when the cue ball hits the rubber edge or target. These four factors affect the result of hitting the ball. Impact point
The cue ball has many hitting points. The better the player's skill, the more effectively he can use all kinds of subtle collision points to make the cue ball spin subtly. But for beginners, as long as the nine basic collision points in the picture can be followed, the cue ball can be effectively transported.
(1) impact center point
(2) At the center of impact (putter ball)
(3) Under the impact center (pull rod ball)
(4) Hit the right side (right spin ball)
(5) Hit the left side (left spin ball)
(6) Hit the upper right (rotate the putter ball right)
(7) Hit the upper left (left rotating putter ball)
(Hit the lower right (turn the pull rod ball right)
(9) If you can know the landing point and rotation of the cue ball by hitting the lower left (the left rotating pull rod ball), then you have really come into contact with fancy billiards. You can master the essentials of billiards on the basis of hitting the ball. The hitting points of cue ball are basically divided into middle hitting, top hitting (putter ball), down hitting (drawbar ball), right clicking (right-handed ball), left hitting (left-handed ball), right-handed hitting (left-handed putter ball), right-handed hitting (right-handed drawbar ball) and left-handed hitting (left-handed drawbar ball). The putter ball hits the top of the cue ball, and the cue ball will roll forward after being hit. After the cue ball touches the target ball, it will roll forward with the direction of the target ball. The pull rod ball hits the bottom of the cue ball, and the cue ball will roll backwards after being hit. When it hits the target ball, it will retreat. The spinning ball is hitting the side of the cue ball. After being hit, the cue ball will spin forward like a top. We can hit different landing points on the cue ball, so that it has many different changes when it goes forward, and there are also many different changes after hitting the target ball. In the bag-dropping fancy pool game, it is necessary to make the cue ball hit the target ball and shoot the target ball under the bag, so the forward route of the target ball after being hit must be considered. Therefore, in these two different competitions, there must be different choices for the landing point of the cue ball. When you want to practice playing cue ball, you must start by practicing playing the center point. When you spin the cue ball forward and sideways, the cue ball will change subtly after being hit. Players should also gradually master subtle changes with the gradual improvement of technology. For beginners, before learning the impact of other impact points, they must be familiar with the impact of the central point. If you play snooker, more than half will hit the ball by clicking the ball in the center. When you hit the ball with a club, try to keep the club level. Beginners will hit the ball a little lower than the center point, which is easy to cause mistakes or fouls. The reason for this phenomenon is that the nose of the right hand is too high or too low. You can know whether you hit the center of the cue ball or not by hitting the cue ball at right angles to the edge of the rubber. If you hit the center of the cue ball with the correct hitting action, the cue ball will still bounce back at a right angle after hitting the edge of the rubber. If it bounces back at a right angle and leans to the left or right, it means that it missed the center when hitting the ball. However, if you hit any point on the vertical axis (the center point is above or below the vertical axis), the cue ball will still bounce back at a right angle. Although there are only nine basic points, there are actually countless impact points for impact, so there may be countless changes after the cue ball is hit. Beginners must thoroughly learn the hitting point of the central point before learning the other eight basic hitting points and more subtle hitting points. There is no shortcut except learning step by step. It is related to the lower stroke (above the cue ball), the draw stroke (below the cue ball), the English of the spin ball and the side of the cue ball. When you learn how to hit the center point, if you are playing snooker, you must consider how to shoot down the target ball you are aiming at smoothly. And in order to continue hitting the ball, we must also consider where the cue ball should stay after hitting the first target ball, so as to easily shoot down the next target ball. Sometimes, in order to avoid the cue ball from bathing (cue ball falling into the goal bag), it is necessary to carefully consider its landing point. Beginners can gradually master the essentials of hitting the ball, and then they can practice pushing, pulling and spinning the ball repeatedly, or they can practice it repeatedly with the target ball and the rubber edge. Basic theory of billiards 4: aiming point and contact point
The so-called aiming point is the direction that the club head faces when you hit the cue ball, and the part where the aiming point contacts the cue ball is called the contact point. When the cue ball hits the target ball, the target ball will move along the extension direction of the straight line connecting the center points of the two balls at the moment of hitting. If the extension line of this line is facing the bag, the target ball will fall into the bag impartially. Because if this extension line is facing the ball bag, it means that when the cue ball touches the target ball, the cue ball, the target ball and the ball bag are just in a straight line, and the source of strength is the contact point of the cue ball and the target ball on the extension line. However, as we mentioned before, the ball and the bag are rarely in a straight line at the same time. Therefore, we can apply this "extension line connecting the center point" to the basic ball gathering technology and develop a technology that can shoot the target ball under the ball bag. More specifically, if we want to easily find the correct aiming point on the target ball, we must first draw a line from the center point to the center point between the target ball and the bag you want to shoot down. The tangent point between this imaginary line and the periphery of the target ball is the ideal aiming point. Basic theory of billiards 5: imaginary center point
When the target ball is shot down, the aiming point on the target ball is fixed, but when the cue ball is used to hit the target ball in different positions, the contact point of the cue ball is different because of the different positions. When the cue ball, the target ball and the ball bag are not in a straight line, you should imagine that there is an extension line connecting the center points of the cue ball and the ball bag. When you hit the cue ball at the target ball, if the contact point between the cue ball and the target ball is just on this imaginary line, the target ball will move towards the ball bag. At the moment of contact, the center point of the cue ball is the imaginary center point. To put it more clearly, we can imagine that there is a ball just close to the target ball on the line between the target ball and the center of the bag, and the center of this imaginary ball must be on this imaginary line. When you hit the ball, you should hit the cue ball at this imaginary ball position. When the cue ball is hit at this position and touches the target ball, at the moment of contact, the cue ball, the target ball and the ball bag are just in a straight line, and the target ball will fall smoothly. It is not easy for a novice to set an imaginary center point or play cue ball at this imaginary point, and it may take a lot of time to get familiar with the essentials. In addition, the change of cue ball speed and the different degree of rotation will make the target ball change very subtly. When you hit the left or right side of the cue ball, you will always move in the direction pointed by the club head before it hits an obstacle (other ball or rubber edge). Beginners often inadvertently hit the club to the right when they want the cue ball to hit the right side of the target ball. Because when we want to shoot the target ball into the bag, we must hit the cue ball to the imaginary point. First of all, you should remember that these basic hitting methods and the thickness of hitting the ball will affect the forward route of the target ball, because this is the only shortcut to improve your skills. As for the complicated calculation, control the cue ball in a position where it is easy to shoot down the next ball, and you will be skilled. Basic theory of billiards 6: the power of hitting the ball
(1) When the impact force is weak,
(2) When hitting with normal force
(3) When hitting the ball with a strong force (the forward route is slightly curved)
It is impossible to explain the strength of cue ball by scientific methods such as photos or pictures. We can only explain it in an abstract way, such as using vague words such as hard hit, middle hit, weak hit and ordinary hit. If you want to control the cue ball according to the power path, you must feel the sense of speed when hitting the ball and practice it repeatedly. There is no other shortcut. Every time you hit the ball, the strength can't be exactly the same. Even subtle differences will make subtle changes between the cue ball and the target ball, so we can only experience it slowly from the actual swimming pool center. Whether it's bag-dropping fancy pool or pool-opening, the intensity of pool-hitting must be well controlled to make the next impact easier. The impact force will affect the separation angle of the cue ball after hitting the target ball, so that the cue ball will hit the same place. As long as the impact force is slightly different, the separation angle will change. The strength of hitting the ball varies from person to person. For beginners, almost all of them hit the cue ball with the same strength, and almost all of them are very hard. In fact, they don't need much strength to play cue ball. Too much hitting power may not make the ball go further, but it is easy to make mistakes when it is too strong, and sometimes it is difficult to achieve the expected effect when it is too weak. However, as long as your skills are improved, you will gradually master the essentials of strength. In billiards, as long as you can flexibly use the hitting force and the rotating hitting method, your skills will be more advanced.
