It can be proven, using the axiom of choice, that there are games—even with perfect information, and where the only outcomes are "win" or "lose"—for which neither player has a winning strategy.) The existence of such strategies, for cleverly designed games, has important consequences in descriptive set theory.

Game theory is a branch of mathematics that studies the strategic decision-making of individuals or groups in competitive situations. It involves analyzing the potential outcomes of different strategies and how they may be influenced by the actions of others.
When there are no winning strategies in game theory, it means that there is no single optimal decision or set of decisions that will guarantee a player's success in a game. In these cases, players must consider the actions and potential reactions of their opponents in order to make the best possible decision.
Yes, game theory can be applied to a wide range of real-life situations, such as business negotiations, political campaigns, and even personal relationships. It can help individuals and groups make more strategic decisions by considering the potential actions and reactions of others.
While game theory can be a useful tool for decision-making, it does have some limitations. It assumes that all players are rational and have perfect information, which may not always be the case in real-life situations. Additionally, it cannot account for factors such as emotions or ethical considerations.
In some cases, game theory can be used to find a solution to a conflict by identifying a "Nash equilibrium," which is a strategy that no player can improve upon by changing their own strategy. However, in situations where there are no winning strategies, game theory can help individuals or groups understand the potential outcomes of different decisions and make the best choice based on their goals and priorities.
