Preface

The stones do not come into contact very much in the

opening stage, so on the surface it seems reassuringly

peaceful. On the other hand, judging what the biggest

moves are can be perplexing. Everything is too vague -

it's hard to establish a criterion for evaluating different

moves. Yet if you neglect the fuseki, you can't hope to

make progress at go. After all, it's the basis of your whole

game.

The fuseki is certainly amorphous, but concealed within

it are a number of key points, points of crucial importance

to your overall development. Gaining an understanding of

what these points are is certainly a sure way to improve.

In this book I have selected what I consider to be the 20

key points of the fuseki and explained them with concrete

examples. This book is made up of three chapters, but the

division is not very significant. I recommend that the

reader treat my 20 principles as proverbs and familiarize

himself with them until they become second nature

factually several traditional go proverbs are included).

Knowledge of these principles will help you to develop a

deeper understanding of the fuseki and to master its basic

strategy. That in turn will make you a much stronger go

player.

I would like to thank the go writer Murakami Akira for

his help in putting together this book.

Glossary

aji - potential (options, possibilities)

atari - the threat to capture a stone or a group of stones on the

next move.

Chapter One

Fuseki Fundamentals

fuseki - the opening moves of the game (usually defined as

lasting until the first fight begins).

gote - a move not requiring an answer; losing the initiative.

Compare sente.

A common pitfall in studying any subject is to rush

on to the more advanced areas before one has properly

mastered the basics. To avoid making that mistake, I

would like to begin by reviewing the fundamental prin-

ciples that really are basic to an understanding of the

fuseki.

bane - a diagonal move played from a friendly stone in contact

with an enemy stone.

joseki - a set sequence of moves, usually in the opening. Locally

they are the best moves for each side.

miai - points of exchange; interchangeable point.

moyo - a large territorial framework, potential but not actual

territory.

ponnuki - the shape made when a stone is captured by four

enemy stones.

sabaki - making light flexible shape in order to save a group.

sente - a move that must be answered or an unacceptable loss

will be suffered.

tesuji - a skilful tactical move.

Principle 1

Corner enclosures aim at side extensions

Dia. 1: the key point for both sides

An extension in the direction of 1 is the biggest point on

the board. Thanks to Black's solid base in the corner, there is a

strong possibility that the area between the corner enclosure

and the extension will become black territory. White would

also like to extend to 1 from his corner enclosure below, so we

can conclude that 1 is the key point for both sides.

After an enclosure, what next?

The first steps in the fuseki emphasize the corners. When

you play a 3-4 stone, in particular, you should waste no time

enclosing the corner This will usually build about ten points

of secure territory.

However, the value of an enclosure is not just the points

of territory it surrounds. Securing a solid base in the corner

makes it easy to develop along either side from the corner.

Dia. 2: looking like black territory

If White responds with an extension of his own at 1, the

idea is to expand Black's territorial framework into the centre

by jumping to 2. The area inside the extension is now begin-

ning to look like black territory.
