The author, on nearly 500 pages, discusses the tactics and mate patterns. The material is sorted into chapters as shown in pictures 2 to 4. From the foreword: .. that’s the main idea of the book: to be a companion for trainers and players who seek improvement — simple but effective! .. What’s crucial is understanding and sub-consciously memorising these patterns in order to recognise when they’re about to occur in a player’s own games .. Each mate’s theoretical pattern is presented as a diagram, with constructed examples and actual games. Further information about the book and a sample are available at thinkerspublishing.com
