I am excited to share a recent tsumego book I've been working on with Chen Hsi (Leon) 陳禧 4p and Chen Feng 陳鋒 5p, two professional players from Taiwan - the title of the book is called Planet, and it contains 136 originally-created tsumego puzzles, which have their own names and stories. There aren't many tsumego collections by contemporary authors, but we are hoping that this series will qualify for the list in the long run!
If you would like to find out more about this book, please visit the original OGS Forum post: https://forums.online-go.com/t/planet-2 ... zles/34003.
A free sample can be found here on OGS Puzzles as well: https://online-go.com/puzzle/27301
Thanks for reading and I hope that you'll enjoy this collection!
