[Diagram]
Hane

With B5, Black chooses to go for influence towards the right.


[Diagram]
An unbranched sequence

After B1, this sequence, in which Black sacrifices two stones, is almost invariably played.


[Diagram]
Finishing the joseki

The joseki finishes with these moves. Black of course throws in at B1 to connect his stones, after which White extends to W2 or plays tenuki. Depending on the position, W2 is sometimes played at a instead. Neither side is in a hurry to capture the stones that are in atari: those are not worth much at the moment.


[Diagram]
Incorrect sacrifice

Although the two black stones are intended to be sacrificed, Black should not hurriedly do so with B1 and B3 in this diagram. Black does build some thickness, but his shape is not impressive, and he also ends in gote.


[Diagram]
White's error

Thus, Black first plays the forcing move at B1. If White answers at W2, Black is now satisfied with playing the sacrifice manoeuvre of B3 and B5. The exchange of B1 for W2 is a very large plus for Black. To avoid this result, White takes away a liberty from the black stones, which results in the joseki sequence.


[Diagram]
After a white tenuki

As said, White often switches elsewhere rather than playing at a (or B1). One option which is available for Black is to push from above with B1, forcing White into a low position with W2.


[Diagram]
Attack

Alternatively, Black could attack with B1, forcing White to walk out in awful shape.
