Unless there is only one black ball left on the table or there is no way to play a live ball. In the latter case, it must be assumed that, according to the referee's judgment, the batter does try to play the live ball, as long as he directly or indirectly hits the main ball in the direction of the live ball with enough strength, but for these blocking reasons, the main ball will reach the live ball.

In the latter case, the live ball should be the same live ball hit by the last ball before this. That is, any red ball, in which the red ball is a live ball. After all the red balls leave the field, the colored balls are live balls. After the red ball falls into the bag, the colored ball is the one chosen by the batter under the condition of live ball.

In this case, other appropriate punishment measures can be taken: the next player can choose to hit the ball by himself, or he can ask the offending party to slam the next player in the stop position. If the above situation still occurs after being declared empty in a row, any warning that may be awarded to the other party is still valid. (5) All other empty shots are announced according to the referee's judgment.
(6) After the empty shot occurs, the next player requests to put the cue ball back in its original position, and any disturbed target ball should remain in its current state, unless the referee thinks that the offending player will benefit from it. In the latter case, with the consent of the referee, any or all disturbed balls can be returned to their original positions. But in any case, the colored balls that leave the table abnormally should be placed at the ball release point or returned to the original correct position.
(7) After the empty shot, when any ball is put back in its original position, the position of the ball can be consulted with the offending party or the next player, and then the referee's decision will finally end.
(8) When asking for advice, no matter which player touches any ball in the middle of the game, he should be punished as a batter. The original competition order remains unchanged. If necessary, the touched ball should be put back to the position recognized by the referee, even if the ball has been picked up by the referee, it is not allowed to touch the ball.

But there must be an additional condition, that is, it must be announced that the situation must change within a certain period of time. Usually, under the judgment of the referee, each side is limited to three strokes. For example, when the announced time is up and the situation is basically unchanged, the referee will cancel all the scores and rearrange all the balls, just like the beginning of a game.

26, explain:
(1) All provisions and clauses in this rule are equally valid for women.

Note: This rule is the latest version published by World Professional Taiwan Province Association and International Federation of Taiwan Province 1995. 1976-82 rule
Nock billiards introduced the ranking system for the first time after 1976 Snooker World Championship. At that time, it was mainly to determine the seed players for the next World Championships. The initial ranking system was quite simple, only considering the players' world championship achievements in the past three years. The champion and runner-up got 5 points and 4 points respectively. 3 points for three or four students, 2 points for four or eight students, and 8- 16 students 1 point. Ray reardon, the then champion of three world championships, became the first player ranked first in the world since snooker was introduced into the ranking system with a score of 15.
1982-04 rule
The above scoring rules were reformed in the 1982/83 season. With the emergence of new events, the World Professional Billiards Association began to consider the results of these events into the ranking system. In the following years, jameson International (Snooker), Professional Players Championship (later LG Cup, Totesport Grand Prix of Snooker), Snooker Rada Classic, Snooker UK Championship and Snooker UK Open became ranking tournaments. Later, the scoring rules developed and changed almost every year, adding and withdrawing new gifts in the ranking system, and constantly adjusting the scores of various items.
2004- 10 rule
In the 2004/05 season, there are eight categories of events with world ranking points, namely: the LG Cup of Snooker, the British Open of Snooker, the British Open of Snooker, the Welsh Open of Snooker, the European Open of Snooker, the Irish Masters of Snooker, the Snooker Players Championship and the Snooker World Championship. In addition to the World Championships and the British Championship, the winners and runners-up of these events will receive 4000 and 3000 world ranking points respectively. The third and fourth place is 2050 points, entering the top 8 is 1750 points, and so on. 200 points out in the first round. However, the points in the World Championships and the British Championship are twice as high as above and 1.5 times respectively. In the 2005/2006 season, eight events won the world ranking points. They are: en:Grand Prix (original: en:LG Cup), en:British Open (snooker), en:UK Championship (snooker), en:Welsh Open (snooker), en:Malta Cup (snooker) (later changed to en:European Open (snooker). En:Irish Masters (snooker), world snooker china open and The World Champions.
The overall rule is this:
1.2009-20 10 season has 6 qualifying matches; In chronological order, they are Shanghai Masters, Grand Prix, British Championship, Welsh Open, China Open and World Championships. The ranking points are champion, runner-up, semi-final, quarter-final and eighth-final. There are 32 people in each round, 16 people lose points, and * * * five rounds; Each round of 32 participants has two scores, one is the lower ranking and the other is the highest ranking, the latter is half of the former; The scores of a ranking match from high to low are (taking the World Championships as an example): 10000, 8000, 6400, 5000, 3800, 2800/ 1400, 2300/1/50. Other competition points are converted according to a certain proportion of World Championships points. The Shanghai Masters, Grand Prix and China Open are 70%, the British Championship is 80% and the Welsh Open is 50%. There are only six events left in the ranking competition. Except for the points of the Welsh Open and the World Championships, the points of the other four races have all been updated, especially the points of the Shanghai Masters and the China Open have changed in Judah, and the champion points have increased from 5,000 to 7,000. In addition, the points of the Grand Prix and the British Championship also increased slightly, from 6,250 points to 7,000 points in the Grand Prix and from 7,500 points to 8,000 points in the British Championship. One can imagine the change of the points system, and the importance attached by the Taiwan Federation to the China market. In addition, it is not clear why the World Taiwan Federation should greatly improve its ranking score. One reason may be to balance the points compared with the 2008-09 season, because the final official ranking is two seasons' points, while last season was eight ranking matches, and the total points of champions were 654.38+00000 points more than the season.
20 10- latest rules
20 10, 10 In June, a landmark event happened in snooker: Robertson broke the monopoly of Handelli and "75 Sanjie" for 2 1 year, and Higgins was more than 9400 points ahead of Robertson at the beginning of the season! Robertson's seemingly impossible feat is largely due to the new ranking system and its timing. According to the new points policy, the official ranking of players has changed from the total points of two seasons to the total points of two years of participation calculated by nodes, and each season contains three nodes. In this way, players can get four ranking updates in a season.
The new system will set up three demarcation points in the season to update the player rankings. This will be a two-year rolling list, so in the 2008/09 season, the corresponding competition points will be deleted at each stage. This means that the official top 16 players are not sure whether they can participate in the Masters in 1 month or the World Championships in Krusburg in April. They need to perform well at all times of the season to maintain their ranking. The old ranking system was updated after the World Snooker Championship.
