Joseki of the week 2

The joseki for this week is encountered often.
After black plays a close pincer, White immediately plays the 3-3 invasion.

The Joseki this week is when black plays for influence along the left side.

Black 3 in the above diagram is necessary instead of a hane to the third line.
If black does hane, white descends to B17, then cuts at E16.

b is an important point for both sides to decide whether white gets sealed into the corner.

If black has a stone on the Top side around c, then he might play 9 in the above diagram at a instead, giving black a strong wall facing the left side.

If there are any questions about the joseki of the week,

Joseki of the week 1

This is the second in the series of joseki that may be posted occasionally weekly.

The diagram shows a 4-3 pincer joseki. Here black plays at 5 instead of the more common a or b.

White would like to connect 2 and 4 from the above diagram, but can’t immediately succeed.

The correct move is for white to play D18 first.
Now if black saves C15, white can trade and capture D16-17,
which is usually a happy result for white.
