Large avalanche  

W4 and W6 is the avalanche joseki. If Black plays B7 and B9 here, then we get the large avalanche.

If either player wants to avoid these complications, White can play at a or play tenuki (move elsewhere) with W8, or Black can play at a or b with B9. These are described in large avalanche simple variations.

Large avalanche  

In the large avalanche, W1, B2, and W3 are all forced. Next, Black can choose amongst a, b and c. Here a is the oldest variation, b is newer and c is most modern, having been introduced by Go Seigen in a game against Takagawa Kaku in 1957. Nowadays, the turn inward at c is the most popular variation, while the turn outward at b is also still played often. The cut at d is a recent development.
