A wonderful set of problem books from Cho Hye Yeon 9p who explains in great detail how to think over each of her Life and Death problems. Lots of diagrams and explanations in both Korean and English.

Cho Hye Yeon also has an English blog which she infrequently updates nowadays.
Her Korean facebook account seems to be where she posts nowadays.
