Contingent strategies are well known, but this book will often make them more explicit and formal than they sometimes are in the game theory literature. Nested games may be a novel topic to the game theorist, as the concept comes from applications in political science, and are crucial to the distinction of a private from a public sector. “Imperfect recall” is very little mentioned in recent game theory, and needs to be discussed in the context of cooperative game theory.
