Double Hane
  Difficulty: Beginner  

[Diagram]
Diag.: B1, B3: double hane

A DoubleHane is - as the name already suggests - two hanes played in sucession. Usually it is quite a powerful play, if the local situation allows it.

AKA Two-step hane. -- Bill Spight


[Diagram]
Diag.: Double hane on the 3rd line

Black 3 is a powerful play as it shuts White into the corner. White cannot counter Black 3.

mat But what about W a, B b, W c? Ahhh I see (first think, then edit...): white captures 3 and black captures the three white stones!

[Diagram]
Diag.: The counter fails

Black captures the marked stones and kills the corner as well. As Black 3 in the diagram above is such a powerful play, White has actually made a mistake before and should have extended to Black 1 above herself.

Add more examples if you feel like it :o) --ArnoHollosi

Scartol: Well, I tried to play through the possibilities for the following question, but due to my DiffcultyReading, I couldn't sort it out.

Diag.: White lives?

Suppose white plays at 1 here, instead of 'a'. Can black still kill the corner?

Jan: I think the idea of the original double hane is not to kill white, but to prevent white from escaping. If black omits '3' in the original diagram, white could later play 4 or 'a' in the following for a substantial gain in territory. Your white 1 lets black make a Trumpet Connection with very good thickness.
