4-5 point 4-3 approach outside contact/discussion

A common response to Black opening with on the 5-4 point is White to invade at the 3-4 point with (4-5 point 4-3 approach). Black attaches "on the outside" with , White hane's with , Black quietly backs off with , and White connects to the outside with .

Although a is a common next move, see the following diagram for another possibility.

Black can turn at instead of cutting. After Black cuts at and White connects with , is a well-timed jab.

Care to guess what White should do ?

In this case it would be wrong for White to capture a stone by playing at ^[1] .

Instead, White should come out with . Black connects out with , White turns with , Black runs twice with and .

However, the interesting reading question comes up here.

It can be verified that if White presses once more with c, Black can kill White in the corner by responding at b .

Hence after Black , White should make life by attaching at a ^[2] .

The fact that Black was supposed to play a instead of attacking with implies that is too aggressive.

How should White take advantage now ?

As far as I can tell, the Get Strong at Joseki 2 book does not answer this question, but since the book does say Black should play a instead of , the question begs to be answered.

Eric Osman: Looks like a good start, but can't Black put up a more interesting fight with a instead of ?

unkx80: I don't think black can win the capturing race.
