3-4 point high approach low extension

    Keywords: Joseki
One-space extension  

This is a Kitani joseki from the 1940s - though not exclusive to him. Black aims to make B1 a very solid stone.

Normal continuation  

Up to W6 is standard. In this case B5 leaves no weakness behind (compare with the case of black+circle at a). This is a tight way to play.


In this crosscut variation, White gets a small corner in sente, while Black, after B11 at a is developing on both sides. Before AI this was considered favorable for Black. AI however likes White better here, with its preference for territory and sente.

Former joseki  

Before AI, this was considered correct and has been played in 2001 in a number of pro games. Black takes a larger corner but White takes influence. AI thinks having this large corner territory in sente is very good for Black.
