What is the status of the white group in the upper left corner?

[Diagram]
Diag.: Moonshine Life


  1. Dead. - one eye dies.
  2. Seki. - White cannot make two eyes but Black cannot kill, because White has infinitely many unremovable threats.
  3. Alive - the white stones cannot be captured, so the "eye" should be worth 1 point.
  4. No result - if Black insists on playing the ko, a triple ko occurs


--Bass


This is the earliest known rules dispute, involving an ambiguous pronouncement by a Japanese monk called Nyobutsu. The status of the top left white group has been regarded differently over the centuries, and modern rulesets do not agree.

I took the liberty of moving this from the MoonlightLife page. Moonshine Life is the usual name for this.
