Diagonal Jump  

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.)


Occurrence in joseki

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.

[Diagram]
A continuation  

This 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 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. See 3-4 point low approach two-space high pincer hazama tobi.

[Diagram]
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.
