Fuseki
Fuseki is a Japanese go term meaning arraying stones.
Fuseki (布石 or 布局 in Chinese) is the whole board opening in the game of Go.
This normally occurs in the first moves of a game so fuseki is often used as a synonym for opening. Rarely, there are games that have no fuseki, rather fighting begins almost immediately.
Joban is the Japanese term for the first moves of a game regardless of the presence or absence of a fuseki.
