If you ever wanted to know, why this problem has not been solved by professionals yet, you can find the answer in this book.

A short overview:

The Problem p. 7

Our Solution p. 8
... in one diagram.

Igo Hatsuyoron – Re-Evaluation by Amateurs p. 9
Introduction.

The Reference Path p. 11
In this chapter, we explain the professionally confirmed sequence with the strongest moves for both sides. White wins by two points !!!

Variations of the Reference Path p. 19

Key Results p. 51
In this chapter, we present in chronological order the main results, and findings.

The Decisive Moment p. 63
This chapter explains, in detail, the move (an Oki), which lead to the refutation of the known (professional) solutions.

Hidden Aspects of the Oki p. 69
In this chapter, we examine various aspects of the Oki, which we think could have been responsible for the effect that the professionals did not use it in the decisive moment.

Guzumi at Top Right p. 75
This chapter explains the consequences of the move (a Guzumi), overlooked by professionals, which we think gives the victory back to Black.

Additional Results p. 87
In this chapter, we consider some earlier commentaries concerning the Seki in the lower right corner.

After the Guzumi – Our Solution p. 91
In this chapter, we explain the main variations after the Guzumi in the upper right corner. Our solution ends with three points for Black.

About Approach-Move Liberties p. 119
This chapter explains an effect, which is important in conjunction with the Guzumi.

About Hanezeki p. 123
This chapter explains the problem's element in the lower right corner.

A Summary of Our Solution p. 127
We wrote this synopsis primarily to give an outline of our solution, but also to highlight some of the problem's main features and interdependencies, in an attempt to clarify the structure.

Acknowledgements p. 135

References p. 137

Postscript p. 138
After the book was in final proofs, we heard about a recently published book, "Research on Weiqi Fayanglun", by Cheng Xiaoliu 6p. This is an updated and extended edition of his 1988 book "Weiqi Fayanglun New solutions".
It was too late to integrate his findings, concerning problem 120, in our book, so we give a brief overview about his results here. Some more of our findings (but not all !!!) can be called "professionally validated" now.

Glossary p. 139

Is it available in any e-format? Best would be Smartgo but PDF or any other non interactive format would be good enough too.

No, it isn't yet.

Gunnar Dickfeld from Brett-und-Stein publishing house is in talks with Anders Kierulf to get an idea about time, effort, and conditions, to have some of his books published as e-book.

But I fear that this will become a long-term project.

If you are looking for some SGF-files, these can be found either on our website or at

http://www.harryfearnley.com/go/trmdpe/ ... -2009.html

The commented SGF-file presents our knowledge as of mid 2008, but should be more than sufficient to understand the problem, especially the Main Path and its variations.

The third edition of our book (with four times the volume of the first edition) has become part of Anders Kierulf's library of SmartGo Books recently:

I'm still having trouble with some of the easiest problems ever created. The one I find trickiest is this one:

Is there a way to purchase this without dealing with Spamazon? If so, I would like to order a copy.l

As preliminary information appending the current state of the first chapter of a book that should be widely available (in paper) in the foreseeable future.

From the book's cover:
The most difficult of all Go problems, created by Inoue Dosetsu Inseki (1646 - 1719), has still not been solved by professional Go players.
“How do you eat an elephant ?” is the usual management consultant’s reply, when being asked how to manage a project that is much too large to be treated as one single entity.
This book comes across with 120 slices, cutting down the problem in size.
We present, and explain, many small aspects of Igo Hatsuyôron 120 as (more or less simple) individual problems. Hopefully, this will make the reader fit to put together the entire puzzle on his own (to be honest: with some assistance, of course) in the very end, i.e. solving the most difficult problem ever.



Further information will be gladly given here. Or via the email-address that is given in the file.

Update:

I am delighted that two publishers intend to include "An Elephant in Slices" in their library:

-- David Ormerod from GoGame Guru (in paper), and
-- Anders Kierulf from SmartGo Books.

Unfortunately, it will take some time until the publication.

-- David has several other books to come in his publishing pipeline already, so the "Elephant" must queue up.
-- Transformation into the SmartGo Books format will also last a while.

So far, some teachers, and players up to 6d, liked the idea that is behind the pedagogical concept of the book.

Wow, it is really cool that Igo Hatsuyoron has been published in English. I wonder how many English speaking players are really strong enough for this book though.

This is about just one problem from igo hatsuyoron. So far the only book for more problems is a fairly old one from Yutopian.

The "Elephant" is an introductory book to the problem, so most of the problems are not so very high level.

Quite the contrary, there is the risk that some readers might find some easier problems somewhat boring. As boring as checking the 100 blue puzzle pieces for creating the sky one by one, but from which each single one is necessary. And in the end they will enjoy the whole picture.

Cho HyeYeon 9p will publish an English translation of the entire Igo Hatsuyôron in her "Baduk Classic" series some when in the future.

Our publications are only about problem 120, the most difficult problem ever created.

We dedicated a website to Inoue Dosetsu Inseki's masterpiece, containing all the results of our investigations in the problem:

We will be pleased to respond to suggestions, questions, and comments, here in this thread.

I earn nothing with the books, so hopefully this post is not contrary to the forum rules.
