In this book, a multinational array of top grandmasters explain the differences in thinking between professional and amateur players and how to bridge the gap. It's worth noting, that here amateur generally refers to players with a rating of 2200/2300
It usually takes at least a decade of sustained effort for even the most talented player to reach the grandmaster level and though this book cannot guarantee to make the reader a grandmaster, it is certainly a healthy nudge in the right direction.
The book also dissects typical mistakes made by amateurs. The mistakes they make are not obvious and so this provides valuable insight to the reader.
Who should read this book?
This book comes highly recommended for advanced players who are serious about their game of chess.
