Best.
Black 1 limits White moyo while building up
Black's. And if White makes the natural
follow up at 6 to protect his two stones,
Black 7 is good enough. Black has altered
the moyo balance in his favor.
Good, but...
Black 1 (or A) are good moyo building moves,
but overlook a serious weakness. After
White leans in with 2 and 4, Black clearly
has a worse result than the best line above.
Overplay.
Black 1 goes too far. After White 4, Black
has two problems: White is reducing Black's
moyo, and Black's lower left group has no
guarantee of living.
