Go is a mind sport, possibly the greatest mind sport ever invented. Improvement in any sporting arena requires practice, dedication and in some cases blood, sweat and tears. Mind sports do not normally include the blood and sweat but do require practice, dedication and may result in tears of frustration. Diabolical life and death problems along with normal life and death problems are a training tool for people seeking to improve their mind skills. Solving problems is an essential tool for people to improve reading skills in much the same way as lifting weights is important for most physcial sports. This book contains 50 problems originally presented in Diabolical Volume 1 published in February 2021. This book is intended for kyu and lower dan levels who are seeking a new way to improve their skills. The books contains the problems as well as the answers and detailed analysis. Purists do not advise looking at answers because the person studying does not get the maximum benefit. I agree but... ...weaker players may never solve some of these problems, but if they study and try to solve them before looking at the answer there will be a benefit. So enjoy the problems; try your very best to solve each one and only look at the answer as a very last resort. Solving a problem without looking at the answer must be your goal because when you can do that you are thinking like a dan player.
