Thinking strategically means anticipating others' decisions and incorporating their incentives into your planning.
It introduces game theory as a toolkit to analyze interactive decision problems in business and life, emphasizing strategic thinking over solitary optimization.
This chapter defines games formally by listing players, available strategies, and payoffs, and shows how to represent interactions in normal (matrix) and extensive form.
It explains dominant strategies, dominated strategy elimination, and how payoffs reflect preferences and incentives.
Simultaneous-move games are ones where players choose without knowing others' current choices; Nash equilibrium identifies strategy profiles where no player can unilaterally improve their payoff.
The chapter explains existence, multiplicity, and interpretation of equilibria as stable predictions of play.
When pure-strategy equilibria don't exist or are exploitable, players may randomize over actions; mixed strategies assign probabilities to pure moves and can produce equilibrium.
The chapter shows how randomization makes players unpredictable and balances opponents' incentives.
Sequential games model situations with ordered moves and observed actions, using game trees to represent choices; backward induction solves these by reasoning from the end of the game to the beginning.
Subgame perfect equilibrium refines Nash by requiring credible optimality in every subgame.
