Jacob Aagaard presents the reader with a few key concepts in the endgame and invites him to test his skills with a lot of examples from recent tournament practice. Where many endgame books are theoretical and emphasise memorisation, This book is based entirely in the real world, where the ability to react precisely in technical positions is a life skill. "I strongly believe in training by solving exercises and Jacob Aagaard is a real master here. I often train my own students using the books from his Grandmaster Preparation series, and they really help on the way to becoming an International Master or hopefully even a Grandmaster." -- From the Foreword by GM Karsten Müller
