Description

This book is based on my articles in the British Go Journal numbers 102 to 120 (1996-2000). Six articles covering the definition of Type 1 to 6 fights, plus the summary overview, were published in the Belgian Go Journal, translated into Dutch by Stefan Verstraeten.

Most of Chapters 1 and 5 was included in The Second Book Of Go

If you have already read all the BGJ articles, then the main new material is Chapter 4, which mirrors Chapter 1 but looks at capturing races involving ko. Chapters 3, 6, and 8 are mostly new too.

In Chapter 1, I introduce six types of fights

  • Type 1: No eyes, at most 1 inside liberty.
  • Type 2: No eyes, at least 2 inside liberties
  • Type 3: One eye versus no eyes. This is widely known as Me Ari Me Nashi
  • Type 4: Big eye versus same size big eye.
  • Type 5: Big eye versus a smaller eye. This is called O Naka Ko Naka in Japanese
  • Type 6: Small eye versus a small eye.

On page 1, I define liberties as the unoccupied points directly adjacent to stones and mention that this is a simplification that will be extended later. On page 16, after introducing approach moves, I redefine liberties as the number of moves it takes to capture the stones. If I want to refer to the dame on a group after that, I use physical liberties.

Use of Japanese terms

I have deliberately made minimal use of Japanese terms in order to make the book easy to read for beginners. The ones I have used are: sente, gote, hane, seki, ko, tesuji.
I have not used semeai, dame, or Me Ari Me Nashi etc.

Specific terms related to capturing races

inside liberty
outside liberty
eye liberty
exclusive liberty
physical liberty

Comments

I carefully avoid using the terms mutual liberties and shared liberties, which are the cause of a lot of misunderstanding.
I hate the expression Eyes Win Semeais, which is a terrible proverb designed to ensure that weak players stay weak. It is a mistranslation of Me Ari Me Nashi. I shall comment on the relevant pages later.
