igo hatsuyo-ron

motto:“It is a matter of life and death, a road

either to safety or to ruin. Hence it is asubject of inquiry which can on no accountbe neglected.”

Sun Tzu: The Art of War

preface:This problem collection was com-

piled around 1710 by Inoue DosetsuInseki, fourth head of the Inoue houseand fifth Meijin Godokoro. It was de-signed for training of the best studentsof the Inoue school and was kept secretfor a long time.

Igo Hatsuyo-ron consists of 183mostly insanely difficult problems andis aimed at serious players with deepinterest in the game. While solving theproblems takes many months, possiblyeven years, finding the solution is al-ways particularly rewarding.

I wish you enjoyment and improv-ing in the wonderful game of go, weiqi,baduk, or whatever you like to call it.

addendum:I have reformatted the origi-

nal files for both iPhone view-ing and creating A6-booklets. Ob-serve that Igo Hatsuyo-Ron (Dis-cussion on Tactics) is one of themost difficult problem collections.
