Cutting Point
   

A cutting point is an empty point between two chains of stones. If the opponent plays at that point, the two chains are cut .

[Diagram]
Diag.: cutting point

Black has a cutting point at the circled point.



If the cutting stone can be captured immediately, there is no cutting point.

[Diagram]
Diag.: no cutting point

In this position, a White move at the marked point puts itself in atari. Black's stones are in fact connected by a HangingConnection.



[Diagram]
Diag.: Threat to cut

White can of course threaten to cut. After White 1, there is again a CuttingPoint at A, so Black now has to connect there. White 1 is called nozoki.



In the following diagram, the marked Black stone protects the CuttingPoint in a fancy way (see KeimaConnection). If White cuts, her cutting stone will be captured in a ladder towards the bottom, or in a loose ladder towards the left. So in a broader sense, there is no cutting point, yet this position contains some aji.
