Compromised diagonal and dropping back

  Difficulty: Expert   Keywords: Joseki, Ko, Shape

This sort of pattern on the side is quite common after an invasion:

White drops back  

You could call W3 a dropping back idea; it is certainly also a getting ahead idea. In this case Black doesn't cut with Black a, White b, Black c because White d is a tesuji of the flying-off kind.



To play W1 at a is clearly slower and heavier, even though it has more effect on Black too.


Here is a very special case of this shape.

An unusual shape  

This choice of B1 (instead of Black at a, in the 3-5 point low approach one-space low pincer) is an example of a play that is recorded in joseki dictionaries, but rarely seen in pro games.



From what is said at weak player's diagonal, one can understand the rarity: Black at a is very natural from the point of view of shape. Of course B1 can be called a lighter play.

This example game in which B1 was played (Kori Toshio?-Kajiwara Takeo (B) 1982-03-04) is a good example of Kajiwara's style. We join it at Black 33.[1]

Moves 33 to 40  

Presumably W2 is intended as a sort of inducing move. Black wastes no time playing B3 at another key point of White's diagonal.

[Diagram]
Moves 41 to 50  

Kajiwara was nicknamed 'the drill' for his maximum attitude to local play: B5 is a good example. A ko results.

[Diagram]
Moves 51 to 60  

Black wins the ko. This leaves White needing a move to live in the lower right.

[Diagram]
Moves 61 to 70  
[Diagram]
Moves 71 to 80  

Another ko: Black trades away the upper right.

[Diagram]
Moves 81 to 90  

Here B5 (dropping back with a diagonal play) shuts White in, rather than chase him out into the centre.

[Diagram]
Moves 91 to 100  
[Diagram]
Moves 101 to 110  
[Diagram]
Moves 111 to 120  

By W10 (move 120) this is the endgame. Black won by resignation, at move 213.
