Best.
Black cannot effectively attack the center
White group, so the game's focal point is
what Black can do with his moyo.
Black 1 works best with both Black's wall
and Black's upper right corner stone.
If White tries to invade with 2, Black 3 blocks
to create an ideal box like moyo shape.
Second best.
Black 1 is solid, but doesn't use all of Black's
stones as effectively.
The top center is wide open for White.
Inferior.
Black 1 expects White to respond in the
upper left corner, but White will pincer
with 2, which nips Black's moyo in the bud.
Bad.
Black's strategy with 1 is misguided.
Black's move "leans" on the White center group
that is fairly immune to attack.
White 2 ignores Black to make an ideal
extension.
