Every club player knows the problem: the opening has ended, and now what? With this new edition of his award winning book, International Master Herman Grooten presents to amateur players a complete and structured course on how to recognize key characteristics in all types of positions and how to make use of those characteristics to choose the right plan. You will learn the basic elements of positional understanding: pawn structure, piece placement, lead in development, open files, weaknesses, space advantage and king safety. You will master the art of converting a temporary plus into other, more permanent advantages. Each chapter of this fundamental primer ends with a set of highly instructive exercises. This new 3rd edition has, besides various corrections and improvements, a new introduction and a brand-new chapter called 'Total Control' with new exercises.
