Respond to attachment with hane
Path: GoProverbs   · Prev: TakeOffStonesCapturedInALadderAtTheEarliestOpportunity   · Next: HaneAtTheHeadOfTwo
    Keywords: Proverb

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.

One of the possible continuations

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

Another possible continuation?

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

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



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 RespondToAttachmentWithHaneDiscussion.


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.

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.
