Recently, some people have been proposed, and the "block head still child" is recovered, called "remember the living system". It means that each chess should stay at least two eye positions, can not be filled, so they do not count on the ground. I consider it, I feel that this rule has a certain reason. Its main benefit is to achieve the completeness of Go rules.
The so-called "completeness" is a rule that can be handled, and the processing result does not change due to factors such as time, place, human subjective idea. And the result of the same situation is completely objective and constant. The current Go rules are incomplete. The most typical situation is that there are some officials who have not received it in the final ending. How to determine the victory? You will say that this is a very low-level mistake, and it will not appear, but as the completeness of the rules, it is necessary to give a way to deal with this situation.
Therefore, if the rule is changed to "how much the number of different discs are calculated when calculating the final situation". Note that it is calculating the number of children, regardless of living, a dead. Therefore, the two endmen will consciously take the other party's dead and in their own air. Its essence is "block still child". This is like this, even if the two sides have official sisters, this rule is movable. The "do not mention three", "single robbery", "single robbery", etc., and it is not meaningless.
Of course, this specified is also a shortcoming, that is, the Finance is too trouble. However, I think this regulations are suitable from the perspective of "Aesthetics".
