Whether your primary interest is to improve your card game or put together a political coalition, here you will be enjoyably instructed in an approach to strategy that has caught the imagination of a generation of readers.

He discusses poker; game theory, as it applies to games but mainly to business; the strategies of buyers and sellers; and finally military and other applications.
