Build Chess.pro, a brand-new, fully functional online chess platform inspired by Chess.com. This is a NEW website, not an upgrade. It must be a real playable platform, not a mockup or fake dashboard. Make it responsive for Android, iOS, tablets, and PC, with modern design, custom chess logo/favicon, light/dark mode, mobile-friendly controls, smooth animations, and customizable boards and pieces.

CHESS GAME: Implement complete standard chess rules: legal moves, check, checkmate, stalemate, castling, en passant, pawn promotion, draws, resignation, timeouts, move history, SAN, PGN, and FEN. Include tap-to-move, drag-and-drop, legal-move highlights, board flipping, sounds, replay, and game saving. Validate all moves server-side.

PLAY ONLINE: Real-time multiplayer using WebSockets or equivalent, quick matchmaking, rated/casual games, play-a-friend challenges, private invite links, rematches, draw offers, resignations, disconnect/reconnect support, synchronized clocks, and real game results. Support Bullet, Blitz, Rapid, Classical, Daily, and custom time controls with increments.

COMPUTER: Integrate genuine Stockfish AI with multiple difficulty levels, player colors, hints, engine evaluation, and analysis. Ensure the engine really loads and calculates moves; never fake AI responses.

RATINGS: Use Glicko-2 or another established rating system. Track separate Bullet, Blitz, Rapid, Classical, and Puzzle ratings, provisional ratings, rating changes, peak rating, wins, losses, draws, streaks, and rating graphs. Add global, friends, country, and club leaderboards.

PUZZLES: Daily puzzles, rated puzzles, Puzzle Rush, survival mode, puzzle battles, tactics (forks, pins, skewers, sacrifices, checkmates), hints, verified solutions, explanations, history, and progress tracking.

GAME ANALYSIS: Use Stockfish to review games, identify inaccuracies, mistakes, blunders, best moves, missed tactics, and checkmates. Include an evaluation bar, move-by-move analysis, opening identification, accuracy estimates, engine variations, and PGN export.

OPENINGS & LEARNING: Opening explorer, opening names and ECO codes, move statistics, beginner lessons, tactics, strategy, endgames, checkmate training, interactive exercises, master-game replay, and learning progress.

TOURNAMENTS: Arena, Swiss, and round-robin formats where supported; public/private tournaments, registration, time controls, automatic pairings, live standings, tie-breaks, results, and winner announcements.

SOCIAL: Unique user accounts, profiles, avatars, optional biographies, friends, follows, challenges, private messages, notifications, blocking, reporting, clubs, club tournaments, and moderation. Include privacy settings and online status controls.

PROFILES & ARCHIVE: Show ratings, peak ratings, statistics, recent games, achievements, puzzle progress, tournament results, and public game archives. Allow users to search players, games, clubs, and tournaments; replay games; import/export PGN; and save analysis.

EXTRA MODES: Support Chess960, Three-Check, King of the Hill, Crazyhouse, and custom positions only when their rules are fully implemented. Add achievements, customizable board themes, sound settings, coordinates, premoves, promotion preferences, and accessibility controls.

ACCOUNTS: Secure registration/login, unique usernames, password hashing, password recovery, sessions, email verification where available, profile editing, guest mode, and account deletion. Never store plaintext passwords.

TECHNOLOGY: Use a compatible frontend, secure backend, persistent database, real-time networking, a trusted chess rules library, and Stockfish WebAssembly or a legitimate engine service. Store users, games, moves, ratings, challenges, puzzles, tournaments, clubs, notifications, and settings. Keep API keys and secrets server-side.

ADMIN & SECURITY: Protected admin dashboard, user management, reports, moderation, tournament management, error logs, rate limiting, server-side authorization, input validation, and basic fair-play safeguards.

FREE & TESTING: Prefer free/open-source tools. Clearly disclose infrastructure limits and required API keys. Test chess rules, multiplayer on two devices, clocks, matchmaking, ratings, Stockfish, puzzles, authentication, database persistence, mobile layouts, and security.

Build in stages: (1) chessboard, rules, accounts, and Stockfish; (2) real multiplayer, clocks, and saving; (3) ratings, profiles, and leaderboards; (4) puzzles and analysis; (5) tournaments, clubs, and social features; (6) security, testing, and optimization.

FINAL RULE: Every button and feature must work or be clearly marked unavailable. No fake players, hardcoded statistics, simulated matchmaking, fake engine moves, or temporary-only storage presented as permanent. If backend services or setup are required, explain exactly what is needed. Build Chess.pro as a real, usable chess website, not merely a visual copy of Chess.com.
