Trick play

In the small avalanche joseki, B5 (instead of a) is a trick play that may be played when the ladder at b is good for Black. The refutation for White can be hard to find however.

Tesuji

W1 is natural to prevent the ladder, but after B2, it seems that White has a problem. The tesuji at W3 saves the day.

Tesuji continuation

With the moves up to W7, Black can cut off W1, but White takes the corner and manages to escape with W7 as well.

If White tries to avoid being sealed in by playing W3 at W5, Black will connect under at W3, and White's horrible shape quickly becomes apparent.

Falling for the trick play

With W3, White has fallen for the trick play. With the moves up to B8, Black seals white into the corner while cutting off W1. White can push through at a, but b is atari, forcing White to capture, after which Black can finish his wall with a move at c.
