Bulky Five

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

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 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:

  • the play at a doesn't work if the bulky five is crammed into the corner, as this will create a Bent Four in the Corner
  • 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.

In dutch we call this one the axe. Don't know why by the way ^_^

Charles In English, 'hatchet five' - I actually think that's better.

Andre Engels To N.N.: The reason is the shape, with the four points being the blade and the one point the handle. To Charles: I think the two (axe and hatchet) are actually the same word in Dutch, so there is no real 'better'. In fact, the Dutch meaning would be closer to hatchet, because the diminutive is used - 'axelet' would be a better translation than 'axe'.

Charles I did mean better than 'bulky'. Hatchet is euphonious, anyway, and carries an air of menace too.
