How to Play

3. Click on a piece to select it, then click on a highlighted square to move
4. The AI will automatically make a move after you
5. Use the "New Game" button to start a new game

AI Opponent

The game includes an AI opponent with four difficulty levels:

• Level 1: Beginner level, makes basic moves
• Level 2: Intermediate level, slightly more challenging
• Level 3: Advanced level, more strategic play
• Level 4: Expert level, provides a good challenge

The AI uses either the Stockfish chess engine (if available) or a random move generator as a fallback.
