This position is the main line in the Kobayashi fuseki. With 7 black invites white to play kakari at A which black will reply with B which induces white C enabling black to create territory at the bottom with D.
This fuseki pattern was not invented by
but he was the most prominent player employing this
pattern in top-title matches so soon the pattern
became known as the Kobayashi Fuseki.
This all happening in the 1980-1990 decade.
More recently Chang Hao the Chinese top pro is seen to employ this pattern frequently.
Nearly the same
Of course, the exact position of white 6
is not important. The white ikken-tobi
is played frequently as well although
a little less than the keima in the main line.
White adjusts her strategy
Since the normal kakari at A would be according to
black's plan white usually keeps a little distance
with 8 as in this diagram.
Preventing the Kobayashi pattern
With 6 white prevents the Kobayashi pattern altogether.
Also this pattern is quite popular.
