Preface

I wrote these notes and pictures during Mr. Yang’s lecture entitled “How To Destroy and Preserve Territory”, presented at the 2000 Gaithersburg, Maryland, Yang Go workshop. While I have discussed the pictures with Mr. Yang and subsequently enhanced the manuscript, any errors or omissions in the final copy remain strictly my own.

Acknowledgement

I’m happy my student and friend, John C. Stephenson, has done a nice job of presenting and publishing notes from my lecture, for which I gave him both permission and encouragement.

I hope many players get a good benefit from his effort.

Picture Studies

Picture One

No Moyo in a Diagonal Opening
Black to play

A is really bad in this case because there is no moyo. B opens the corner. C is a good relationship with the corner star-stone. D is flexible but is not good for territory.

Picture Two

Multiple Purposes
White to play

A has only one purpose (to help the left). B and C have two purposes so they are better than A. B and C help white on the left and also open possibilities on the top. After B, D becomes urgent for black. Then, white should not play a jump out to E (the fifth line) unless it has multiple purposes.

Picture Three

Approaching the shimari
White to play

A is a good preventing move. B is a standard move in a moyo game.

Picture Four

Key Point
Black to play

Diagram 4

1 is the key point. If black just plays at A, it’s bad when white jumps out to 3 keeping a step ahead.

Picture Five

Side extension
Black to play

Play A for defense. Two lines is a good number for defense. Or, play B for development. Five lines is a good number for development, and B has a reasonable follow up at C. (Also, three lines or four lines is generally not good, unless there is another compelling reason.)

Afterword by
John C. Stephenson

Amateur 4-Dan (AGA)

Mr. Yang, a 7-Dan Go professional, author and extraordinary teacher, possesses an uncanny knack to instruct people of all rankings. He is somehow able to pull profound lessons out of amateur games of any level. His teaching style is both gentle and insightful, with advice expressed through clear and immediately applicable concepts, sprinkled with a sense of humor. Yet at the same time, it’s intense.

As a full time practicing professional for well over ten years in the United States, Mr. Yang conducts workshops throughout the country, gives lessons on the Internet and comments game records by e-mail. As many players of a variety of strengths have happily discovered, instruction from Mr. Yang deepens one’s game and dramatically adds to one’s enjoyment of go. Mr. Yang’s teaching is truly a remarkable experience, and unlike any other’s.
