One, and sometimes more engines, toil without rationing electricity, sometimes checking on their master's ideas or more oft en showing their own evaluations and recommendations on screen with each conclusion supplemented by an exact numeric equivalent. There is no arguing with such an expert. Is it even necessary? He, as the almighty judge, knows all and can answer any question. All that is needed is patience. During a mutual training session, a young player who is currently one of the top in the world, asked Garry Kasparov: "How did you evaluate positions in the past?" After all standard evaluations like "better" or "worse" are too vague and cannot begin to satisfy a modern professional. Th e very question feels like a giant gap between the approach to solving chess problems then and now. Intuition and improvisation are gradually phased out by exact knowledge and calculation. So far this has only become fully evident in the opening. More than anything else it has become opening preparation which has made the biggest fundamental change to professional chess. So now let us peer behind the curtain!

This book focuses on a subtopic of explainable AI (XAI) called explainable agency (EA), which involves producing records of decisions made during an agent’s reasoning, summarizing its behavior in human-accessible terms, and providing answers to questions about specific choices and the reasons for them. We distinguish explainable agency from interpretable machine learning (IML), another branch of XAI that focuses on providing insight (typically, for an ML expert) concerning a learned model and its decisions. In contrast, explainable agency typically involves a broader set of AI-enabled techniques, systems, and stakeholders (e.g., end users), where the explanations provided by EA agents are best evaluated in the context of human subject studies. The chapters of this book explore the concept of endowing intelligent agents with explainable agency, which is crucial for agents to be trusted by humans in critical domains such as finance, self-driving vehicles, and military operations. This book presents the work of researchers from a variety of perspectives and describes challenges, recent research results, lessons learned from applications, and recommendations for future research directions in EA. The historical perspectives of explainable agency and the importance of interactivity in explainable systems are also discussed. Ultimately, this book aims to contribute to the successful partnership between humans and AI systems. Features: Contributes to the topic of explainable artificial intelligence (XAI) Focuses on the XAI subtopic of explainable agency Includes an introductory chapter, a survey, and five other original contributions

This book is not a pure (auto)biography, rather a games collection. It consists mainly of interesting high-class games played by me, including many losses. Most of the games are preceded by accompanying texts, which vary from essays to tournament reports. The title of the book might seem presumptuous, but I wanted to show how I see or experience the competitions without denying the chess worlds of others. While the texts are mostly light and subjective, at the same time I tried hard to stick to the facts and provide some food for thought. GM David Navara May 2020.

With the ascent of computer technology, humans have a chance to develop their thinking process in chess based on hard evidence. Think Like a Machine explores human limitations and proposes new avenues for human thinking, inspired by computer engines. In positions taken almost exclusively from modern tournament play, the authors present jaw-dropping continuations which humans struggle to find, not due to lower human computing power, due to conceptual and perceptual limitations. In this book these "crazy" moves are analyzed and categorized. If you want to expand your chess imagination, understanding and intuition, Think Like a Machine is the book is for you.

Bestselling author and eminent foreign policy scholar Zbigniew Brzezinski's classic book on American's strategic mission in the modern world. In The Grand Chessboard, renowned geostrategist Zbigniew Brzezinski delivers a brutally honest and provocative vision for American preeminence in the twenty-first century. The task facing the United States, he argues, is to become the sole political arbiter in Eurasian lands and to prevent the emergence of any rival power threatening our material and diplomatic interests. The Eurasian landmass, home to the greatest part of the globe's population, natural resources, and economic activity, is the "grand chessboard" on which America's supremacy will be ratified and challenged in the years to come. In this landmark work of public policy and political science, Brzezinski outlines a groundbreaking and powerful blueprint for America's vital interests in the modern world. In this revised edition, Brzezinski addresses recent global developments including the war in Ukraine, the re-emergence of Russia, and the rise of China.

The three-times World Chess Solving Champion distils the most useful middlegame concepts and knowledge into 100 lessons that everyone can understand. Following on from his successful Understanding Chess Endgames, John Nunn turns his attention to the middlegame - the phase of the chess battle where most games are decided, yet the one that has received the least systematic treatment from chess writers. With the outstanding clarity for which he is famous, Nunn breaks down complex problems into bite-sized pieces. In the case of attacking play, we are shown how to decide where to attack, and the specific methods that can be used to pursue the enemy king. Positional play is described in terms of the major structural issues, and how the pieces work around and with the pawns. Nunn explains how to assess when certain pieces are better than others, and how we can make use of this understanding at the board. Readers will never be short of a plan, whatever type of position arises. Each lesson features two inspiring examples from modern chess, annotated honestly and with a keen focus on the main instructive points. Both sides' ideas are emphasized, so we get a clear picture of the ways to disrupt typical plans as well as how to form them.
