Descent in the avalanche  

Like the Avalanche Connection line, B1 keeps matters simple by accepting white's offer to exchange black corner territory for white center influence. W2 is more or less the only move, after which black can choose between B3 here and black a, which is discussed below. White has little choice in this variation, but she should not be dissatisfied - playing the avalanche means white is going for influence, and that's what she gets, in sente moreover. Black could play black a, white b, black c instead of B5. That way he does not need to slide down to the second line, but white's wall is one stone longer.

Push  

After B1 and W2, black can convert to the previous variation, but more usually he will play the clamp of B3, either directly as shown here or after yet another push as shown below. With W4 white chooses a peaceful variation, giving up her influence along the top to make influence on the side instead.

Fight  

With W4 a fight breaks out in this upto now so peaceful joseki. White does however need a working ladder, or at least a big ladderbreak?, as we shall see below. The three black stones are stuck against white's wall, which itself does not have eyes yet either. For now, however, black needs to do something about his corner group first, as white a is sente

Exchange  

In fact, white could play W1 (a in the previous diagram) instead of W6 immediately, leading to this exchange where each side captures three stones, and white's switch from the top to the left is even more outspoken.

Ladder  

The ladder occurs if black tries to cut with B5 - squeezing with a is not a satisfying result for white.

Second push  

If black pushes once more, more or less the same variations follow, although of course the exchange variant is not possible any more.
