Taisha solid connection

  Difficulty: Expert   Keywords: Joseki

This page deals with the standard pattern, following the complex variation of the taisha joseki (also known as taisha tobitsuke), where B1 makes a solid connection. The other two major patterns are a, taisha nobi 1 and b taisha nobi 2.


This is the most common development, after a while the groups in the center develop shape.


Black 1 here has been played by some top players down the years (Shusai, Sekiyama Riichi, Hashimoto Utaro). The line continues with W2 and B3, and is thoroughly analysed in Ishida.

An apparent impossibility  

Black B1 here is a pro play, though rarely used. Examples include Weon Seongjin (4p) vs Lee Yeongkyu (2p) in 2003 andKubomatsu-Kitani in 1934. This is a pushing battle with a hamete in it. Black B3 may look as if it's easy to refute - but beware the two-stone edge squeeze!


This idea appeared in a couple of Go Seigen's games in the 1930s.

Shuwa's move  

Black B1 and B3, not mentioned in Ishida, were played by Shuwa.


That leaves these plays a and b from Ishida unaccounted for; they may be outright tricks. Analysis is given there for a; for b too but that was played differently 1974-06-06 by Hashimoto Utaro against Magari Reiki (game on Gobase).

Gobase also has a game 1973-10-31 between 1 dan pros Inoue Hatsue and Kimura Yoshio in which Black tries c.
