Double low approach, tenuki  

It is rare for Black to play elsewhere in response to the 4-4 point double low approach, and allow W1 to shut in the 4-4 point stone, because White gets superb influence while Black can only make small life? in the corner.

Canonical joseki  

B2 at the 3-3 point is the canonical joseki typically given in Go textbooks.

The hane of B2 is painful, but is necessary for life. See joseki-related life-and-death example 4 for more discussion on the life-and-death issues surrounding this position.

White too thick  

Typically Black will not play at B8 and allow W9 to cut in sente.

White too thick  

After B2, White can play elsewhere. In this variation, it is generally recognized that White is very thick, unlike the canonical joseki where White has cutting points.

Go Seigen recommendation  

Go Seigen recommended this sequence over the canonical joseki, which gives Black unconditional life with potentially more points while giving White cutting points. However, the life-and-death of this group is a lot more complicated than that of the canonical joseki, hence this sequence should not be recommended in high handicap games.

Gobase sequence  

This sequence is found in Gobase. It appears that the B6 and W7 exchange is not absolutely necessary.

Exchange  

According to Gobase, the W3 here leads to an exchange.

Later, Black can regain part of the corner by playing at a.

Tenuki again  

There are a few instances where Black chooses not to make life in the corner. In such cases, W1 can turn the whole corner into White's territory.
