3-4 point high approach, keima
  Difficulty: Intermediate   Keywords: Joseki

[Diagram]
Keima

This choice of B1 is very steady. Usually Black isn't planning any complex variations here, but to keep sente and create a solid position on the left side.

For pro use of this joseki, see the keima joseki in fuseki.

White's reply

After that Black at a is the standard play. The pincer at b is quite a new development in joseki (though played by Takagawa 50 years ago). Occasionally Black plays at c, but this leaves an obvious weakness and bad aji near a. Black tenuki at this point is rare (though in a game in the Honinbo book shows it, quite a rare case in which knowing a pro play can be detrimental).

For White tenuki now, see 3-4 point high approach, keima, tenuki.

Black's answer 'a'

After B1, the main line here, an extension to one of a, b and c is expected: which then ends the joseki. It seems that the tight extension at a has become more popular than c; the play at b will be made in connection with some overall consideraion. White directly at d is also seen.

Black's answer 'b' (1)

After B1 White commonly plays into the corner with W2, and B3 gives Black some sort of development on both sides.

Andre Engels: I cannot find any extension like B3 in my game collection. Black either connects at a, or plays tenuki.

Charles Two examples I have (Gogod) are Takagawa games from 1954 (as old as me). A recent one was Yoda Norimoto-Kobayashi Koichi 2002-02-18 in the Kakusei final.


[Diagram]
Black's answer 'b' (2)

There is also a fighting line, set off by W2. After some moves on the outside, Black goes back to a to live in the corner.


[Diagram]
Black's answer 'c'

After B1 this way, W2 is normal. Possibly White plays at a. After that an extension along the left side is very big for Black.
