Capture Variation:

Compared to the superordinate variation, ...

  • Black got an additional two points of territory in the left centre.
  • White got an additional two points of territory there.
  • Black destroyed one point of White's territory in the upper right corner.
  • White captured Black's stone in the lower left, so gaining two points.

In total, Black lost one point.

White + 2 => White + 3

Semeai Variation:

At White's decision point, Black's large group at the right will have ten liberties (), so White will be unable to capture this group.
