What to say about a collection of go problems? Overall "I liked this one."
1. I made it to the end, working every problem, getting about 50% right. Seeing the correct answer and explanation for those I missed was useful. Since these are opening problems there may be multiple good moves, but as a kyu player I try to be humble enough to recognize that the authors thinking is stronger than mine. It is foolish for someone at my level to quibble with the answers.
2. Last night my go teacher presented a board diagram during his lecture on the history and evolution of this game... and I recognized the board as one of the problems in this book! So I knew the answer before anyone else watching the lecture. That was a cool moment, and it made me realize that some of these problems are from famous games...I didn't know that while reading the book.
3. Author Rob van Zeijst's 2.5-page Introduction is concise, useful, and the illustration works to make his point. Many problem books don't have introductions this useful.
4. As explained at the beginning of the book, the problems have an "opening principle" printed below the board diagram. This is akin to providing a hint. I tried using a bookmark to cover these up while working the problems, but it's easy for bookmarks to slip and slide. I wish there was a way that these texts could be hidden and made visible by the reader. Maybe an electronic version could perform this?
Yessss. Bijna 3 jaar mee bezig. Ik was met goede moed begonnen maar was er weer vrij snel van afgevallen van de gedachte ik doe elke dag 10 problemen. Ik had er ook in een paar weekenden doorheen kunnen knallen zoals ze in Korea doen. Nou ja ik heb mijn dagelijkse tsumego ook verwaarloosd dus ik ben vrij snel achteruit gegaan in mijn 9x9 spel. Dit helpt vooral in inzicht voor de direction of play, ik had hem ongeveer de helft van de tijd goed of zat in de juiste richting. Het lastigste vind ik altijd goede vervolg zetten vinden na de joseki in het middenspel. Ik zal me maar beperken tot weer oefenen en het 9x9 spel weer oppakken waar ik op het hoogtepunt op ogs zo tussen de 11 en 10 kyu (regelmatig ook wat sterker) speelde. Als volgende het 9x9 boek van Bozulich dan maar..
