In game theory, the term "strategy" refers to a well-defined plan or set of rules that a player follows to make decisions in a particular situation. Strategies are crucial components of games, influencing the outcomes and players' payoffs based on their choices. Understanding different types of strategies and how players employ them is essential for analyzing and predicting outcomes in strategic interactions.

Types of Strategies |
Pure Strategies:
Pure strategies involve a specific, deterministic plan where a player commits to a single course of action. There is no element of randomness or probability in pure strategies.
Mixed Strategies:
Mixed strategies introduce an element of randomness into decision-making. Instead of committing to a single strategy, players assign probabilities to different strategies within their strategy set. The decision to play a particular strategy is then made randomly based on these probabilities.
In game theory, strategies play a crucial role in determining the optimal decisions for players in various situations. Two important types of strategies are pure strategies and mixed strategies, each offering a different approach to decision-making in games.
Pure Strategy Games:
In pure strategy games, each player makes decisions based on a specific, well-defined strategy. A pure strategy is a set of predetermined actions that a player commits to taking with certainty. There is no randomness or unpredictability in the choice of actions, and players choose a single strategy from their strategy set.
Examples of Pure Strategies:
In a game of Rock-Paper-Scissors, choosing to always play "rock" is a pure strategy.
In chess, each move a player decides to make constitutes a pure strategy.
In a penalty kick in soccer, the decision to aim the ball to a specific side without any randomness is a pure strategy.

Advantages and Disadvantages of Pure Strategies |
Advantages:
Simplicity:
Pure strategies provide clear, straightforward decision rules.
Predictability:
Opponents can easily predict a player's moves in a pure strategy game.
Disadvantages:
Vulnerability:
Pure strategies can be exploited by opponents who anticipate and counteract them.
Lack of Adaptability:
Players using pure strategies may struggle to react to changing conditions or opponents.
Mixed Strategy Games:
In mixed strategy games, players introduce an element of randomness or probability into their decision-making. Instead of committing to a single pure strategy, players assign probabilities to different strategies within their strategy set. The decision to play a particular strategy is made randomly, based on the assigned probabilities.
Examples of Mixed Strategies:
In a card game, a player might decide to bluff with a certain probability or play a strong hand with a different probability. In a game of matching pennies, players might choose "heads" with a certain probability and "tails" with another probability.
Advantages and Disadvantages of Mixed Strategies:

Advantages and Disadvantages of Mixed Strategies |
Advantages:
Unpredictability:
Mixed strategies introduce an element of unpredictability, making it challenging for opponents to anticipate a player's moves.
Adaptability:
Players using mixed strategies can adapt to changing conditions and opponents' strategies.
Disadvantages:
Complexity:
The introduction of randomness adds complexity to decision-making and analysis.
Potential Loss of Control:
Players may feel less in control of the outcomes due to the random nature of mixed strategies.
In summary, pure strategy games involve players committing to specific, non-random actions, while mixed strategy games introduce an element of randomness and probability into decision-making. Both types of strategies have their advantages and disadvantages, and the choice between them depends on the context of the game and the goals of the players. The concept of Nash equilibrium extends to both pure and mixed strategy games, providing a fundamental understanding of strategic decision-making in game theory.
