Group
Informally, a group consists of a number of stones of one colour, hanging together as if effectively connected. They are a functional unit on the board, occupying and influencing a certain area.
In this game, 100 stones have been played. The following stones are commonly called a "group"
- the nine white stones
in the lower left
- the three white stones in the upper left
- the black structure
in the upper middle
- the black stones
in the upper right
- the unmarked white stones running from the upper right to the centre
- the ten white stones
in the lower right
- the black stones at the bottom form two groups that are likely to become one, if they swallow the five white stones dividing them, or connecting via one of the points a
The stones in the centre are not all clearly part of a functional unit. The groups identified above, are in different states of stability and development.
