Definition

从原有棋子的同一横线上,向左或向右有间隔地下一子。如果间隔一路,称为"拆一",若是间隔二路,则称 "拆二",其余类推。拆常常用于扩张地盘,或谋得对方的根据地。

An extension is a big fuseki point that extends an existing configuration of one or more stones along the side, leaving several spaces between the played stone and the existing stones. It outlines potential territory towards the edge and/or blocks the opponent's extension (checking extension).

Because moving along the side is so important, it is distinguished from moving toward the center, which is instead called a jump. If a stone is played directly next to an existing stone, it would be called a stretch or solid extension.
