CChess

Welcome to CChess, a simple chess game coded in C that allows you to play against an AI using the minmax algorithm or against another person on the same screen. The graphical interface is built using the ncurses library.

1. Main Menu:

   • Here's the game's main menu, where you can choose between playing alone against the AI or with two players on the same screen.

   

2. Gameplay:

   • Once on the game screen, you can move the pieces by clicking on them with the mouse. If you're playing against the AI, it will automatically play after you.

   

Minmax Algorithm in Chess

The AI opponent in this game utilizes the minmax algorithm to make decisions. The minmax algorithm is a decision-making algorithm used in two-player games, such as chess. Here's a brief explanation:

1. Maximizing Player (AI):

   • The AI is the maximizing player, trying to get the highest possible score. It assumes that the opponent will make the best moves to minimize the AI's score.

2. Minimizing Player (Opponent/You):

   • The opponent, or the human player, is the minimizing player, trying to get the lowest possible score. It assumes that the AI will make the best moves to maximize the opponent's score.

3. Recursive Exploration:

   • The algorithm recursively explores possible moves, creating a tree of possible game states. At each level, the maximizing player chooses the move with the highest score, and the minimizing player chooses the move with the lowest score.

4. Heuristic Evaluation:

   • The algorithm uses a heuristic evaluation function to assess the desirability of a particular board state. This function assigns a score based on factors like piece values, board control, and positional advantage.
