When trying to find the best move, it is often helpful to look at the position from your opponent’s point of view.
Black 1 is the most important point on the board. White is almost forced to defend with 2, after which Black can take up position on the right side with 3.
In place of Black 1, to play at 2 first would be in the wrong direction. White would simply respond at 1 and, depending on Black’s next move, either play at ‘b’ or invade at ‘c’.
If Black neglects to play B, White can turn at 1 in this diagram and his potential for constructing a large territory on the left side is greatly increased compared to Answer B.
Black 1 is the ideal point on the right side. However, after White 2, White’s territorial potential on the left is increasing. It is necessary to limit the size of the left side by first playing 1 in Answer B.
The kakari at Black 1 is certainly a big move, but it misses the most important point. Moreover, compared to the move on the right side, it is not as big.
Since the white stones in the upper left are alive, it is pointless to contain them with Black 1. This gives White the chance to jump into the right side with 2.
Moves as restrained as Black 1 should never be made. Black 1 in Answer E is the correct way to play on the right side.
This book is the first volume of a collection of problems from the popular series which has been appearing in the magazine ‘Igo Shincho’ over the last number of years. It is a unique series in that by solving these problems and recording your score you can get some idea of your actual go strength.
The problems are divided into three parts; the first part consists of 20 problems on the fuseki, the second part 20 problems on the middle game, and the third part 10 problems on the endgame. In each problem you have a choice of five moves. Each move is given 10, 8, 6, 4, or 2 points depending on how good or how bad it is. At the beginning of each section there is a sheet on which to keep your score as you go along with a rating for the number of points scored in each section. [We hope to provide automatic scoring in a future version of Go Books; for now, please keep track of your scores manually.]
If you approach these problems as if they occurred in one of your own games, I’m sure that this book will both be interesting and increase your strength by one stone.
