Of the six-point big eyes, only this one and rectangular six in the corner can be killed. Its vital point is a. It is known as the rabbitty six [1] or nutcracker. It is also known as the flower six because the Japanese term for this shape is hana-roku.
Robert Pauli: Problem 32 in David L. Silverman's Your Move (no other go problems):
[1] The term "rabbitty six" was invented by James Davies. The shape vaguely reminds one of a rabbit's head; the ears are at the top left.
Robert Pauli: Did James really have the (t)y? In German the adjective-noun form sounds funny to me (hasige Sechs...ouch, not a hare, a bunny: karnicklige Sechs). BTW, is 'bunny'' also usable as adjective?
My favorite name for this shape is fish(y) six - makes sense in all directions.
Later...hmm, why not piranha six?
Andy James?: Can't say what Davies called it, but "bunny" is not an adjective in English (unless you want to invent a word for "like a bun.")
cartan: Davies calls it "rabbity six" (one t).
