Act as a senior game developer and AI engineer. I want you to design and build a professional-grade chess application that can be used for serious tournament-level training. Core Requirements: 1. Game Modes: - Two-player mode (local multiplayer on same device) - Single-player mode vs AI (Player vs Bot) 2. AI / Bot Requirements: - The bot must be highly intelligent (tournament-level strength) - Use advanced techniques such as Minimax with Alpha-Beta pruning, iterative deepening, transposition tables, and opening/endgame heuristics - Ability to adjust difficulty levels (Beginner → Intermediate → Advanced → Grandmaster) - Should simulate human-like play styles (aggressive, positional, defensive) 3. Visual Move Indication (Important UX Feature): - Before making a move, the bot must visually indicate: - Which piece it intends to move - The destination square - Use UI highlights, arrows, or animations to clearly show the predicted move - Add a short delay (e.g., 1–2 seconds) before executing the move for better user understanding 4. Chess Rules & Engine: - Implement all official chess rules: - Castling - En passant - Pawn promotion - Check, checkmate, stalemate - Draw rules (threefold repetition, 50-move rule, insufficient material) - Maintain move history and allow undo/redo 5. UI/UX Expectations: - Clean, modern chessboard UI (responsive for desktop + mobile) - Drag-and-drop and click-to-move support - Highlight legal moves when a piece is selected - Show last move played - Optional: evaluation bar (like professional chess tools) 6. Training Features (Important): - Show best move suggestions (optional toggle) - Blunder/mistake detection - Move analysis after game ends - Provide explanations for bot moves (why that move was played) 7. Tech Expectations: - Suggest a scalable architecture - Recommend tech stack (Frontend + Backend + AI engine) - Code should be modular, clean, and well-documented - Include performance optimizations for AI calculations 8. Bonus (if possible): - Integrate with an existing strong engine like Stockfish - Add PGN export/import - Timer modes (Blitz, Rapid, Classical) Deliverables: - High-level architecture - Step-by-step implementation plan - Core code snippets for: - Board logic - AI decision engine - UI move highlighting - Suggestions for further improvements Focus on building a real-world, production-ready system—not a basic demo.
