Starting sequence

[Diagram]
Noseki  

The combination of B2 and B4 is a bit of a trick play just short of joseki. A gobase search yields only 13 games. That's a big clue that it's not joseki, but a situational play. In all the games Black had something in the lower left corner or side. It might be a wall, an enclosure, a 4-4 stone, or an approach from the left side. In one case it was a pincer.

Tricked

[Diagram]
White is tricked  

If White plays like this, her influence obtained towards the bottom will only work if she has some stones there herself. Black has sente and can use it to build at a.

Countertricked

[Diagram]
Correct for White  

This is correct for White. It is important to play the hane at the foot? of W5 before W7 and not to play W7 at a instead [1].

[Diagram]
Continuation  

White's capture is one line higher and therefore much more powerful, also due to the extra forcing move at W6.



[1]

[Diagram]
Not ideal  

White has sente and two forcing moves. But White can do better.



What Ishida says

Ishida's joseki dictionary, volume 2, gives the following a one diamond (= acceptable joseki) rating:

Variation (with fighting)

Joseki  

White can force with 1 and then secure the corner and an outside connection in sente with 3. Also seen is a pro game with W3 at a leading to a large scale fight.

Alternate response  

W1 also occurs, with this continuation.
