A dango is a structure that occurs in the game
Go, made up of four pieces in the following form:
---------
----xx---
----xx---
---------
Dangos are weak structures. Eight of the opponent's pieces are required to surround and thus
kill it:
----00---
---0xx0--
---0xx0--
----00---
Where as a different use of the four pieces:
---0-----
--0x00---
--0xxx0--
---000---
Reqires 9 of the opponent's pieces.
Any additional piece played on a dango:
---00----
--0xx0---
--0xx0---
---0x0---
----0----
Does little good, adding only one
liberty to the structure, where as on the other arrangement, one stone placed provides two
liberties.

Incidently, Dango is also my
ferret.
