Tsuke Nobi Clamp
  Difficulty: Advanced   Keywords: Joseki

[Diagram]
Diag.: 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.


[Diagram]
Diag.: Black builds influence

After black 1, white 2 is the most common answer, but tenuki and white 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.


[Diagram]
Diag.: 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 or black playing A is 22 points. Still, it is only points, and thus considered large endgame.


[Diagram]
Diag.: black's countermeasure (8 connects)

On the other hand, white should not wait too long with playing 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.



[Diagram]
Diag.: 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]
Diag.: 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.

Diag.: Hane

White 3 is the other option in this variation. Black should not omit black 6; this is a key point for both players' eye shape. After white extends with 7, black defends at 8.


[Diagram]
Diag.: Sacrifice

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


[Diagram]
Diag.: 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]
Diag.: White cuts

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


[Diagram]
Diag.: 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.
