This and Ishigure’s “In the Beginning” were my first Go books. I read this as a 15-20k. It was far beyond my ability to understand, but I did learn from it. It’s a very entertaining read. Kageyama has a great attitude about him, and hops from topic to topic in a lightfooted manner.
I’ve reread it around 10k and got a lot more out of it, but it was still beyond me. 5k now, I anticipate that when I return to it as a 1d, it will still be beyond me, and I will continue to learn from it!
