|Settling the corner with one move|
With the 3,3 move (san-san) black settles
the corner in one move. This move is thus
very suitable in fast-paced openings.
If black wishes to further develop this
corner his choices are either A
for large scale development, and B or C
for small solid development.
White's usual approach to this corner stone
is leisurely with B or more direct
with D. Both are discussed below.
|Developing the lower side|
The white 2 approach in this diagram is
used when white wants to develop the lower
side of the board. If the left side is
more valuable white would have approached
the black corner from that side instead.
After black 3 white will play any of the
points A, B or C, depending on the whole
board position and especially the situation
in the lower-right corner. You are advised
to study the professional games to get an
understanding of how to choose between these
|Developing the center|
With 2 white aims to make black low while
settling a group in the center. White will
choose this variation when the center is
more important than either of the sides.
White 6 prevents black A. After 7
black likes to continue with B locally
so usually white will play C to make that
move less attractive.
How to choose the direction of black 3?
After black 5 white could play D and close
the lower side for black (see the next variation).
So usually black 3 is played in the direction
of the side which is not interesting for white to develop.
The white 2-4-6 group is not terribly strong,
Actually it can easily turn out to become a weak group later
on in the game.
|The lower side is important|
If white wishes to build up the lower side
white 6 can be played as in this diagram.
After black 7 white usually makes a three
point extension along the lower side with
either A or B, following the general rule
for extensions: the height of the wall plus 1.
