Renouned Grob Killer
This book was recommended by derschwarzeritter, this book isnt a very known of text, but it turned out to be quite good. It has a much more thorough guide to mating patterns than Vukovics Art of Attack had, I went through the trouble of copying each page it introduced a new mating pattern, and I have found this to be quite helpful, when studying Fred Reinfelds 1001 Brilliant Checkmates.
