Ko fight

    Keywords: Ko, Go term

Chinese: 劫争 (jié zhēng)
Japanese: -
Korean: -

A ko fight is a local situation which is decided or affected by a ko. The fight involves the ko itself and the ko threats.

The basic sequence of a ko fight is thus, with White starting:

  1. White takes the ko
  2. Black makes a ko threat
  3. White answers the threat
  4. Black takes back the ko
  5. White makes a threat
  6. Black answers the threat
  7. White takes back the ko

... and so on until finally

  • Black or White ignores the threat to resolve the ko
  • White or Black follows up on the threat, taking compensation for losing the ko.
