Chess is a game of decisions. As well as deciding about which move to play and which plan to adopt, players must also make practical decisions about how to use their clock time and whether to use intuition rather than trying to calculate every line to a finish. Viacheslav Eingorn draws upon his vast experience to provide guidance on how to weigh the various factors in positions and decide on the best course of action. He examines many practical examples and explains how the critical decisions were made, and investigates whether they were correct. By following Eingorn on this voyage of discovery, the reader will gain a greater understanding of decision-making and develop an enhanced feel for the harmonious use of intuition and calculation.
