There are few books on Handicap Go that attempt to give receipes for good play. Those that do exist advise simplistic, safe, but slightly ineffective josekis. Cosmic Go takes a different approach. The authors teach you to take the severest path in the opening and play on a large scale. They instruct you to create big open spaces and not worry about territory in the beginning. Handicap books will tell you to create thickness but his book will teach you how, and then use it to construct moyos and pick advantageous fights.
