Development is a general term, applied to moves or stones or groups of stones. Stones can develop on a large scale, in which case we can talk about expansion?, or on a smaller scale, in which case we can talk about movement. Next to spatial development, there is also the change over time.
On a small scale, we talk about the way stones move, or walk. It emphasizes the dynamic nature of the act of playing a stone.
- In Korean, such development is referred to as haengma, though the exact meaning of this term is still debated (see haengma/discussion).
- In Japanese, such development is referred to as suji.
On a large scale, we talk about the way a certain position (a stone, a group, ...) can expand. This large scale notion of expansion is probably also covered by the Korean term haengma.
A position and its quality can also change over time without any active spatial development related to it. This aspect of development is also under discussion at haengma/discussion.
