The clamp

White 4 is another option in this joseki. It is often used in an attempt to settle the shape. Black 5 to 8 are a common continuation.

Black builds influence

After Black 1, White 2 is the most common answer, but tenuki and White at 3 have also been played. If White does not play 2, capturing there is a big point for Black as well. Black 3 is a key point for influence, and should not be omitted.

White cuts

Although the joseki has ended with Black 5 in the previous diagram (or White 4 if there is already a black extension on the left side), White is left with the large move of White 1. The difference between White playing here and Black playing a is 22 points. Still, it is only points, and thus considered large endgame.

Black's countermeasure (8 connects)

On the other hand, White should not wait too long to play White 1 in the previous diagram either. If Black's position along the left side is more solid, he could play Black 4 at 1 here, and try to kill the white stones. If White feels unable to resist this variant, her endgame move is at 1 in this diagram.

The other atari

This variant I found in [ext] Jan van der Steen's database and has apparently been played between professionals. Unfortunately, I do not know what Black would have played, had White run out with 3 instead of 2.



[Diagram]
Hane

Black's second choice after White 1 is the hane at 2. White 3 and Black 4 form a very simple variation, after which both players extend with 5 and 6. White 5 could also be played at a, and many other possibilities exist for Black 6.

Hane

W3 is the other option in this variation. Black should not omit B6; this is a key point for both players' eye shape. After White extends to W7, Black defends at B8.

Charles Matthews There are not many pro games in which W3 is played, it seems. But the variations there are rather different: B4 at B6 omitting the atari, or B6 at a. I wonder if this line to B8 is more like a 'handicap game joseki. In even games White is also interested in pushing up to b.


[Diagram]
Sacrifice

White tries to start up a fight with 1 and 3, but Black sacrifices the corner in exchange for extra influence.


[Diagram]
Continuation

Although White has taken the corner, her territory is surprisingly small - only 15 points or so (White will have to take the black stones off the board). Black's thickness is much more valuable.


[Diagram]
White cuts

If White cuts with 1 first, Ishida's book gives this variation.


[Diagram]
Continuation

White manages to capture some black stones, but Black gets a nice amount of territory, and can look forward to a ladder block as well. Of course if the ladder does not work, this variation is even more problematic for White.
