Diagonal Jump

Chinese:象飞 (xiàng fēi), or 象步飞 (xiàng bù fēi)
Japanese: ハザマ飛び (hazama tobi)
Korean: 밭전자 [밭田字] (bat-jeon-ja)

The shape created by the two White stones is called hazama tobi in Japanese. It has the obvious defect at the marked point, but can be a powerful move in the right circumstances.

It is also called an elephant's move, because the elephant in Chinese chess moves this way. (In Chinese: 象飞 (elephant's jump) or 象步 (elephant's step) and 象眼 - the elephant's eye for the marked place.)


In joseki, there are two main uses from the 3-4 point.

[Diagram]

Two-space low pincer

This pincer isn't often played now, so W3 is rarely seen. Popular enough in the first half of the twentieth century.

A continuation

This furikawari idea is a typical sequel.

[Diagram]

Two-space high pincer

This is still current as joseki.

[Diagram]

Towards the Kajiwara joseki

This leads to a large-scale sacrifice variation known as the Kajiwara joseki. White [1] gives up around 20 points in the corner for the sake of imperfect outside influence. Not an easy line in practice. It is still being played by the pros.

Yoda Norimoto (white) vs Cho U, 3th November 2004

BramGo: This variation I saw recently in the 6th Round of the 29th Meijin title. I am not sure if it is something new, but personally, I had never seen it before. After w8 black tenukied, to approuch the corner at the topright of this diagram. White ignored this and played A.

4-4 joseki

White can also play this way for the corresponding 4-4 pincer.

[Diagram]

Pushing battle

White probably played that way to gain influence; so Black 1 and so on are natural, starting a pushing battle in the centre. Black has to be careful not to create difficulties for the corner 4-4 stone, though. It isn't easy to say when Black can or should stop pushing.

Cutting a big elephant?

Frs: Does a Japanese, English or animal Go term exist for Black's shape or/and W1 ?

Sebastian: How about "Mammoth"? For Chinese, I'd propose "猛傌", pronounced "mengma". (This would mean mammoth, if the second character were "獁". By replacing it with the old character for "knight in chess" - which is pronounced the same way - it now reads "fierce knight".)

It's tough to call Black connected, there, so the shape is somewhat nameless like many others... The potential use for such a shape depends so much on the surrounding area. Coconuts

[1] Robert Pauli: Seems, Black and not White is trading corner for influence, not? I searched for "Kajiwara joseki" (with double quotes) and nothing was found??

Charles Try 3-4 point low approach two-space high pincer hazama tobi.

Robert Pauli: Ah, I see. Thanks.


I've also seen this one played a few times jumping to the 2nd line as a tesuji... I'll try to find an example... (Wrote it here hoping somebody else would do it.. ;p) Reuven
