Games Of Strategy

Games of Strategy by Avinash K. Dixit and Susan Skeath is essentially an introduction to game theory—the study of how people, businesses, governments and organisations make decisions when their choices affect one another. The 2nd edition is designed to explain these ideas without requiring advanced mathematics.

What the book teaches
It helps you understand questions such as:
How do I make the best move when another person is also thinking strategically?
How can I anticipate what my competitor, opponent or negotiating partner will do?
When should I cooperate, compete, negotiate or deceive?
How do timing and information affect decisions?
How can you influence the choices available to other people?
Why do apparently rational people sometimes make decisions that produce poor outcomes?
It covers concepts such as strategies, payoffs, rationality, equilibrium, sequential and simultaneous moves, uncertainty, information, repeated games, bargaining, auctions and voting.

The important thing about it
Despite the title, this is not primarily a book about military strategy or board games. "Game" means any situation where your outcome depends partly on what someone else chooses to do.
For example:
You want to reduce the price of a product.
The seller wants to maximise the price.
Both of you know that the other is negotiating strategically.
What should you do?
That's a game-theory problem.
The book applies the same thinking to business competition, dating, politics, negotiations, family situations, auctions, voting and international conflicts. Its opening chapters deliberately use everyday situations to introduce strategic thinking.

For a businessman, it is particularly useful
If you're interested in business, sales, negotiation, marketing or leadership, this book can be quite valuable. It teaches you to stop looking only at your own decision and start asking:
"What will the other person do when they realise what I am trying to do?"
That is the heart of strategic thinking.
In one sentence:
Games of Strategy teaches you how to think several moves ahead when your success depends not only on what you do, but on what other people choose to do in response.
