6? 1 What are the rules of English billiards in the national standard? Thank you, everyone.

Snooker (English) Rules 1. The inside of the snooker table is 350 cm long, 175 cm wide and 85 cm high. The 22 colored balls * * * are divided into 8 colors, including 15 red ball (1 minute), 1 yellow ball (2 points), 1 green ball (3 points), 1 brown ball (4 points) and 650. 2. Before the kick-off, the cue ball can be located at any point in the kick-off area (D-shaped area). Kick-off must first hit the red ball directly or indirectly. Shoot down a red ball in turn, and then shoot down a colored ball until all the red balls fall into the bag. Among them, the colored balls are put back to the original ball release point after falling into the bag. Then shoot down the yellow, green, brown, blue, pink and black balls in the bag from low to high according to the color ball score. When there is only a black ball left on the table, hitting the ball into the bag or making a foul will end the game. At this point, if the scores of both sides are equal, the black ball will be placed again and the last game will be played. At this time, whoever hits the ball into the bag or fouls will end the game. 4. If one of the following violations occurs, points will be deducted (if the score is less than 4 points, points will be deducted according to their respective scores): hit the ball before it stops; When hitting the ball, the club head touches the main ball more than once; Hit a hollow rod; The main ball falls automatically after hitting the target ball; When hitting the ball, the foot leaves the ground, and the cue ball is not placed in the service area (D area) when kicking off; Play a jump ball; Hit the ball out of bounds; The cue ball hits the non-live ball first; When hitting the ball, the player's clothes, body, clubs and clothes touch the ball on the table. 5. 7 points for the following fouls: after hitting the red ball into the bag, hitting the ball without specifying the ball; After playing the red ball, the red ball was played and no colored ball was reported; Use any other ball as the main ball instead of the white ball. 1) There are 22 balls for snooker, including red ball 15, colored ball (1 black, pink, blue, brown, green and yellow) and white ball 1. Red balls and colored balls are used to score points, and white balls are used to hit the ball. Before each start, put the ball in the form of 1 Before the kick-off, both sides can decide who will kick off first by tossing a coin. When kicking off, the kickoff party can put the white ball anywhere in the kickoff area to play the red ball. After that, where the white ball stops, it must be played from where. Each side must get a red ball first, and then choose a favorable colored ball to play. After the color ball is scored, it needs to be taken out and put back in its original position (that is, the position before the kick-off). Then, play with red balls and colored balls, and so on until all the red balls are in the bag. After that, you must play with colored balls in a certain order. That is to say, play yellow ball first, then green ball, brown ball, blue ball, pink ball and black ball. At this point, if you put a colored ball in, there will be one less colored ball on the table (it is no longer necessary to take out the bagged colored ball and put it back in its original position), and all colored balls will be put in the bag, leaving only one white ball on the table, which is the end. The process from the beginning to all colored balls and red balls being hit into the bag is called a game. During the whole goal-scoring process, if one side fails to score successfully or hits a bad ball, then he has to give way to the other side to play. The process of winning goals in succession is called "one shot". The outcome of each game is determined by the number of points scored by both sides, and the one with more points is the winner. There are two ways to score: one is to score by scoring goals, and the other is to score by punishing the other side for their mistakes. Red ball 1 point, yellow ball 2 points, green ball 3 points, brown ball 4 points, blue ball 5 points, pink ball 6 points and black ball 7 points. So both sides will try their best to get more black balls into their pockets. When playing the red ball, if the white ball fails to touch any red ball, it will be fined 4 points; If you touch the colored ball by mistake, you will be punished according to the score of the colored ball, but at least 4 points will be deducted. In other words, if you encounter a black ball, you will be fined 7 points, and if you encounter a yellow ball, you will be fined 4 points. Similarly, when playing colored balls, if you don't hit the colored ball you want to play, you will be punished according to the score of the colored ball; If you accidentally hit a colored ball with a high score, you will be punished according to the high score, and at least 4 points will be deducted. Therefore, after scoring the red ball and before playing the colored ball, in theory, each player must first declare which colored ball he wants to play. In actual operation, if the colored ball to be played is obvious, you don't need to declare it, but if it is not obvious, you must declare it, otherwise you will be fined 7 points automatically. As shown in Figure 2, the batter must first state which colored ball (brown ball, blue ball or pink ball) he wants to play. If you accidentally hit the white ball into the bag, at least 4 points will be deducted, or points will be deducted according to the ball with higher score that the white ball meets before it enters the bag. If the white ball is in the bag, the next player can put the white ball anywhere on the tee. Penalty points are not deducted from the penalty party's points, but added to the opponent's points. Because it is also possible to score through the mistakes of both sides, if one side on the court feels that he has no chance to score, he will try to be a "snooker". The so-called "snooker" is such a situation that the next player can't directly hit the ball to be played, but has to catch a difficult ball such as a rebound ball or a curveball, which is easy to make mistakes and lead to points deduction, as shown in Figure 3. You can play one game, three games, five games and seven games in one game. The final of the world professional championship is to play 35 games. If the two sides are tied in the end, the traditional way to decide the outcome is that the black ball stays in the black ball position and the white ball is placed in the tee area. The two sides decide who plays first by tossing a coin, and the one who scores the black ball first is the winner. 2) Some common rules and applications of snooker The following are some common rules that often confuse novices. Wrong ball: The wrong ball will be fined at least 4 points. If the wrong ball is a colored ball with more than 4 points, it will be deducted according to the actual score of the colored ball. (1) Hit the ball out of the table. (2) Both feet leave the ground at the same time when hitting the ball. (3) The white ball jumps over the middle ball and hits the target ball. (4) The ball on the table is touched by any object other than the hitting end of the club or any part of the body. (5) In the process of hitting the ball, the club hits the white ball continuously for more than two times. (6) The cue, the white ball and the target ball contact at the same time. This often happens when the white ball is too close to the target ball. For example, when the distance between two balls is less than 2.5 cm, it is very difficult to make a foul-free shot unless the target ball is lightly touched, as shown in Figure 4. Therefore, when the white ball is close to the target ball, only the batter is allowed to hit the white ball away, but not the target ball. In this special case, as long as the white ball goes to the target ball, it is regarded as hitting the target ball. A good player often takes advantage of this opportunity to play a safe ball or snooker. Because, at this time, you can only play the white ball without playing any other balls, so it is easy to make a safe ball and snooker, as shown in Figure 5. Free ball: after one side plays the wrong ball, snooker appears on the table, so that the next side can't play the red ball directly, and the next side can choose any colored ball as the red ball to play. This colored ball is called a free ball. If this colored ball is put into the bag, it will be put into the bag as a red ball and get 1 point, and then the colored ball will play as usual. If the red ball on the table has been played, it will appear that the next player cannot directly hit the colored ball to be played. The next player can choose any colored ball to play, which is a free ball. Calculate the score of the free ball according to the lowest score left on the table, and then play the colored balls in the normal order. Play again: If one side plays the wrong ball and puts the other side at a disadvantage, the other side has the right to ask the wrong side to continue playing. This rule, like the free kick rule, is designed to prevent either side from making deliberate mistakes and profiting from them. However, before deciding to let the wrong side play, we must ensure that every ball on the table has no chance and take into account the level of the wrong side. Unconscious save: If the referee thinks that the ball should be hit after one side hits the wrong ball, he can punish the unconscious save. In this case, the beneficiary can have the following options: (1) restore the ball to the original state before the wrong ball and ask the wrong side to play again; (2) Ask the wrongdoer to continue the game at the current position; (3) Call yourself at the current position; (4) If snooker appears on the table, play the free ball yourself.
