Go/Weiqi/Baduk fuseki Chinese low and high
let's see bellow Go SGF File:
The Chinese opening or Chinese fuseki is the opening pattern that is characterized by the black moves B1 B3 B5 (or B1 B3 a) in this diagram. Black is not enclosing the bottom right corner but playing on a somewhat larger scale. The idea behind the opening is that White at some time will be forced to invade somewhere in the framework that Black builds on the right, after which Black will use the attack on the white group to turn another part of it into territory.
There are two main variants, namely the low Chinese opening, which is presented here, and the high Chinese opening, where B5 is played at a. The high variant is more influence oriented, the low variant more territory oriented. Since at least the late 1990s, the low variant has been the most commonly played and has hence become synonymous with the "Chinese opening," without specifying "high" or "low," in contemporary usage.
