Chess for Zebras
Each chapter revolves around a different premise mostly around the chess improvement. He refers to a study that the higher rated a chess player when asked to analyse a position was less emphatic that his analysis was right than lower rated players. That GM's had a higher level of appreciation of the complexity of chess and a inquiring mind to explore the ambiguity of a position.
He also had a premise that most knights would agree with is that improvement comes mainly from activity not studying. Actively working with chess positions, solving problems, playing against Fritz from a won position, looking at a position for 20 + minutes to come up with a plan. Improvement comes from ones ability to know what to do when faced with a position one most likely had never seen before. So the emphasis is the ability to solve problems.
