The proverb recommends to respond with hane to an attachment.

[Diagram]
Black 2 responds with hane.  

White 1 intends to settle up quickly here. When you are weak and the opposition is strong you should play closer to the opponent's stones.

Black responds with hane 2.

[Diagram]
One of the possible continuations  

Before playing 1 (or even before the attachment) white should check if the ladder is favourable for him.

Another possible continuation?  

How about this? (my first edit, just trying ;) )

unkx80: I think not so good. White ends up in gote instead.

Standard joseki  

bud1027: This is a standard sequence.


More examples:

hane to an attachment 1  

Klaus: Here W2 is joseki, even if the hane is on the second line!

[Diagram]
hane to an attachment 2  

And again! W2 is just the right move!

[Diagram]
hane to an attachment 3  

Most of us will know this one...


Beware!!

No hane to a supported attachment!!

Sometimes hane to a supported attachment  

Alex: W2 B3 W4 is playable, making light shape.


An attachment in to the corner stone early in the game is bad for the side that attaches. Discussion about how uncomfortable things go if such an attachment is made could be found in /Discussion.


BobMcGuigan: Like all proverbs this one has exceptions. Often one should respond to an attachment with an extension (stretch). Doing this often gives less help to the attacher, making him/her work harder, and gives the attacher fewer forcing moves.

Charles Matthews That's quite true, but if one looks how pros play it depends rather on the specific situation.

Some examples.

[Diagram]
Typical contact play 1  

For example here W2 is more common as an answer to B1 than White at a, according to a database search I've just run. The advantage of W2 is that it takes away Black's possible sabaki techniques here: we can assume Black is defending, or B1 will be poor in fighting terms

[Diagram]
Typical contact play 2  

Here B1 is more commonly answered with W2 than with White at a, though both are frequent in practice. Black will presumably continue now with B3 at b or c. If W2 is at a then B3 at b is expected. The motivation for playing White at a is often explained as 'not giving Black momentum'. It is actually when White is in a position to attack that one expects to see the heavier response at a from White.

So in both these cases it seems that avoiding the hane answer is connected to a wish to attack with a free hand, by not leaving cutting points.
