Double Hane/ Discussion

Sub-page of DoubleHane

(Sebastian:) Inspired by this article, I just tried this (in [ext] http://kgs.kiseido.com/games/2004/9/18/Socke-Bashan-2.sgf), but I didn't know how to get out of the situation in sente. I was unhappy when I had to play B3, but I couldn't treat B1 as light. Any hints?

Bill: First, you do not have to treat B1 lightly. After B3, W2 is a poor orphan. What is to worry? Second, a is a vital point.


Bill: After looking in vain for a double hane on the Stanley 3-3 Double Hane page, I came here. I believe that the proper term in English is two-step hane. Double hane is ambiguous. Just to make sure I was not out of touch, I looked it up in the 2001 edition of the Go Player's Almanac. There is no entry for double hane. There is none for two-step hane either, but nidanbane is defined as a two-step hane. Is there an example of double hane in the English go literature?

Anonymous: IIRC, the book All About Thickness (English translation) lists a proverb: "Learn the double hane and you are nearly shodan."

Another Anonymous: IIRC, James Davies uses the term "double hane" in his books, too. Also, googling for "double hane" (with quotes) yields lots of hits.

Bill: Thanks for the refs. :-) If Davies uses double hane in his books, I am surprised it does not appear in the Go Player's Almanac, since he was a major contributor to it. I see that van Zeijst uses the term, and withdraw my objection. :-)

Robert Pauli: Anyway, with what can it be confused, Bill?

Bill: Playing hane from two sides, for instance. Like so:
