damezumari
A shortage of liberties. In the first diagram, black 1 has just been played in the knowledge that, due to the damezumari possessed by the three marked white stones, it can be connected to the black stone on the first line. As in the next diagram, if White captures one stone with white 2, then black 3 reduces the liberties such that, if White were unwise enough to play a stone at A, it, along with the three marked stones, could be immediately captured. In the final diagram, the alternative white 2 is captured but otherwise ends up with the same result. |
