Over the past few months, David Mitchell has been working on a TsumeGo book for Dan players which has gone through a rigorous validation process (including a review by An Younggil 8P) and will be available shortly.
There are 100 problems in the book but the answers are NOT included. David is working on problems and answers books using the same problems with the answers and explanations aimed at kyu players. If you need answers, please wait, the first problem & answer book is likely to be published in 3 months.
The real intent of the book is for people to solve the problems themselves without having to resort to looking at answers. Solving problems is a great training exercise that extends and improves reading skills, looking at answers does not help reading skills.
The problems are presented in a totally different manner to any other TsumeGo problem. Each problem is set on a whole board with four or more positions. One position is unsettled, the rest are already settled (no matter who plays first the result is the same).
The task is for Black to win in all positions; Black groups live, White groups die. Black plays first and moves alternate as in a real game. Black does not play first in each position, just one move, so finding the unsettled position is vital. If you want to see how it is done check this video – click here to watch
