PATTERN TWO
The formation here, with Black
having made a three-space extension,
is often seen. Where is the vital point
for invading?
Dia. 1 (invasion). Invading in the middle of Black's threespace
extension is correct.
Dia. 2 (a fight). Defending at 2 or `a' is a solid response. White
will probably jump out with 3 and 5, and Black will turn sideways
to 6. This is reasonable for both. Next, a fight will start.
