Cut
Definition
A cut is a move preventing a connection, or an existing situation where stones are prevented from connecting. Usually the term applies to stones which are in direct contact. 切断对方棋子联絡的手筋。將对方的棋分割成两块,叫分断;切断对方侵入棋子的退路,叫遮断。名称虽然不同,但要领都在于通过切断对方棋子的联络,来获取利益。 切断是基本的战术手段,在很多时候,并不需要手筋的微妙次序而可以直接切断。 从狭义上讲,切断的手筋就是通过周密的次序达到切断对方以尖、飞、一间跳等见似坚固联络形的方法。对薄弱、间隔更大的联络,切断的方法有很多,问题就在于根据周围的状况来选择切断的方法。切断有巧拙之分,要根据全局的形势来判断切断后的好坏。
In the left part of this diagram, Black can connect his two stones at the marked point. In the right part it is shown how White cuts the stones, at . The Black stones will only be able to connect again if the cutting stone is captured.
In this situation we will rather say that separates the white stones. The implication on a strategic level is the same (the stones will not easily connect). On a tactical level,
needs not be captured for the white stones to connect .
Example
Because of the two stones, the
stones are cut off from the living white stones on the top edge.
Principle
Cutting and connecting is a central concept in Go. You are normally well advised to keep your own groups connected and cut your opponent's groups apart.
(See: Divide and conquer)
Solid cuts and crosscuts
It is worth noting that cutting stones are often themselves separated from their group, so if you are cutting two groups to capture one of them, you must make sure that your cutting stones will not get captured first.
In a solid cut, Black cuts the White stones while connecting his own, resulting in a very favourable position where only White has the burden of being cut.
Here, , the cutting stone, is itself cut from friendly stones. This more balanced kind of cut is called a crosscut.
