In life-and-death situations and during the sharp skirmishes that arise in the middle game, brute-force analysis is usually required. However, intuition also plays a role in your ability to instantly find the key move that turns the position in your favor. Those key moves are called tesujis. There are about 45 different kinds of tesujis that a dan-ranked go player should be familiar with. If a player has solved many problems that involve a certain kind of tesuji, he or she will immediately recognize -- almost unconsciously -- positions in their games where that tesuji is applicable. This...

Go is played on a very large board, consisting of 361 playing points. During the opening phase, there will be perhaps 50 to 100 candidates for a plausible move, and, for each of these candidates the opponent's many possible responses must also be considered as well as your responses to each of these responses, and so on. An exhaustive brute-force search for finding the best move is clearly impractical. Clearly, a go player needs some principles to guide him. After the opening phase ends, difficult decisions must still be made in the middle game -- which groups should be attacked and which...

Tesujis are skillful moves that accomplish some clear tactical objective, such as capturing stones or a group, rescuing one of your own groups, linking up your stones, separating your opponent’s stones, making good shape, etc. There are two approaches to presenting tesujis problems. One approach is to collect problems according to the objective that tesujis accomplish. The other is to collect problems according to the kind of tesuji used. In this book the emphasis is on the latter. There are about 45 different kinds of moves that make up tesujis. Each of these moves has a Japanese...

This book is the third volume of the series The Road Map to
Shodan. Part One is intended as an introduction to the topic of life and
death, aimed at players who have just learned the rules. However, it should
also be useful for players up to 5-kyu or for any amateur player who needs
to review the basics of life and death. It is also a prerequisite for Part Two
of this book.

The fundamental concept of life and death is that of eye space. Once
this concept is fully grasped and the properties of various eye spaces are
understood, the...

Good shape is a subject that has received scant attention in Japanese go literature. Although references to shape are made in most books, there is no one book devoted exclusively to this subject. However, understanding and recognizing good shape is important for becoming a strong player and developing intuition that will instantly guide you to find the strongest moves in the opening and the middle-game fighting. Shapes are the building blocks of your groups. They determine whether your stones are working together efficiently or are sitting in each other's way. Good shape is a source of...

In the opening stages of the game, territory and influence are equally important. However, if you concentrate only on making territory and ignore influence, the chances are you will find yourself at a disadvantage later on in the game. In handicap games, the handicap stones are high on the star points and are not efficient in securing territory. It is therefore natural and strategically correct for Black to emphasize influence. However, kyu-level players lack the ability and the confidence to play an influence-oriented game; instead of taking chances on positions in which the territorial...
