Cho just published her Creative Life and Death III, IV and V. Volume I and II was published few years ago and volume III, IV and V completes this series.

Each problem has rate of difficulties. One * denotes difficulty of 5-6d and 2 for 7d and 3 for pro.

She published by herself in paper back to reduce price for Go fans.

If they were being sold on an English website, with a cheat sheet similar to how YMI sells "Lee Chang Ho's Life and Death Set" I'd be likely to purchase them.

The books are written in English and Korean, so there is no need for a translation sheet. Yes a English ordering page would make things more simple. I emailed them about ordering information from that website.

Excellent. That makes them even more appealing.

I had contact with the owner of the website and he says Hye-yeon's book are not available to buy directly from Korea for people in other countries yet. So one will have to wait for the local baduk book stores to stock up on them.
