Bulky Five
  Difficulty: Beginner   Keywords: Life & Death

Bulky five refers to a certain unsettled eye space of five points.

[Diagram]
Diag.: Bulky five

The key point in the bulky five is the marked point. If White plays there, she is alive. If Black plays there, White is dead.

--MortenPahle (10k)

White can also make life by playing below the marked point, can't she?

--Shinnosuke (20-25k)

Yes, White can also live by playing at a (creating an L-shaped four) or at b (creating a zig zag four).

However, there are two points worth noting:

and

  • both a and b leave Black with ko threats: playing at the marked point threatens to kill the whole group.

A play by White at the marked point doesn't have these problems.

--Jan (15k)
