Ponnuki
  Difficulty: Beginner  

[Diagram]
Diag.: ponnuki

A ponnuki is the shape that is created when a single stone is captured, like is done with black 1 in the diagram. Such a shape, radiating influence in all directions, is considered a very good one, as is witnessed by the proverb "A ponnuki is worth thirty points".

DaveSigaty: The interesting question here is whether the value comes from the shape or the act of capturing a stone. I seem to remember reading somewhere that the ponnuki is efficient when it is formed by capturing a stone (effectively building this shape with only three moves). However, if B constructs the shape without capturing a stone it is inefficient. This makes a lot of sense when you think about it. This type of thinking is an important point for us amateurs to understand.
