Those who know the rules of snooker come.

In my impression, I have learned snooker the most, which is 12 times. It's hard to get more than that.

What you said has been solved, but it doesn't actually exist!

If the ball really has no theoretical solution, then the opponent only needs to solve it once, and you have no right to ask him to solve it twice. That is to say, it was just a foul, and there was no unconscious save (miss).

As long as the ball is untied, it can usually be solved within a few strokes. As for why it can't be solved, the player just doesn't want to give the opponent a chance after solving it. If you play hard like you said, it is very easy to leave opportunities for your opponents, no matter whether you can't solve it. At this time, the opponent will definitely not ask the referee to restore the ball and let you solve it again. Winning depends on your own offensive score, not the opponent's deduction.

However, there are also lucky cases in which the ball is scattered. Although it has not been solved, the opportunity has not been missed. If the opponent asks for a reset, the referee has to do it!

There is usually a big screen to help. However, the requirements for recovery are not absolutely strict, as long as the key ball does not shift in nature (for example, it will become visible if it is not invisible).
