This document outlines the planned progression for the multiplayer chess platform, from core synchronization to a fully featured competitive ecosystem.
Goal: Ensure games are fair, stable, and resilient to network issues.
- Server-Side Move Validation: Move the logic from
ChessGame.tsto the C# backend (or a shared library) to prevent players from sending illegal moves via console. - Reconnection Support: Implement a "Game State" cache in Redis or memory so players can refresh their browser and resume an active match.
- GameOver Persistence: Ensure the server officially declares the winner and prevents further moves once checkmate or draw is reached.
- Anti-Cheat Lite: Detect impossible move speeds or multiple sessions from the same IP.
Goal: Make the game feel "alive" and urgent.
- Chess Clocks: Implement Blitz (3m), Rapid (10m), and Classical (30m) timers synced via SignalR.
- In-Game Chat: A dedicated chat panel for opponents to talk during matches.
- Action Notifications: System messages for "Check!", "Draw Offered", and "Low Time".
- Emoji Reactions: Quick-tap reactions (👏, 😮, 😠, 💡) that appear over the board.
Goal: Give players a reason to return.
- User Accounts: Authentication using ASP.NET Core Identity (JWT).
- Match History: A dashboard to view past games, including who won and the total move count.
- PGN Export: Allow users to download the "Portable Game Notation" of their games to analyze elsewhere.
- User Profiles: Custom avatars, win/loss ratios, and "Member Since" badges.
Goal: Build a community and a sense of progression.
- ELO Rating System: Implement a Glicko-2 or ELO ranking system to track player skill.
- Skill-Based Matchmaking (SBMM): Update
GameHubto match players with similar ratings. - Global Leaderboard: A "Top 100" list of the highest-rated players.
- Private Rooms: Generate "Join Links" (e.g.,
chess.com/play/abc-123) so friends can play without the public queue. - Spectator Mode: Allow users to watch high-rated matches in real-time.
Goal: Help players get better.
- Server-Side AI Analysis: After a game ends, use Stockfish on the backend to identify "Blunders", "Mistakes", and "Brilliant" moves.
- Opening Explorer: Show players the name of the chess opening they are currently playing (e.g., "Sicilian Defense").
- Move Heatmaps: Visual representation of where a player most frequently moves their pieces.
- Database: PostgreSQL (for users/history).
- Caching: Redis (for active game state and matchmaking).
- Communication: SignalR (WebSockets).
- Processing: Background workers for AI analysis.
