About the AI

This AI uses a Minimax algorithm with depth-limited search and alpha-beta pruning to make smarter moves.

Minimax Algorithm: Evaluates moves a few turns ahead.
Winning & Blocking: Looks for immediate wins, then blocks threats.
Alpha-Beta Pruning: Skips branches that can’t change the outcome.
Move Evaluation: Prefers lines of three and four with open ends.
Center Priority: Favors the center column for more chances.

Challenging yet fair—like a lightweight chess mindset for Connect 4.
