ChessMate is a real-time, peer-to-peer multiplayer chess game built for instant, low-latency play — no login required. Just register your name, invite a friend, and start playing in seconds.

Designed with performance and simplicity in mind, ChessMate combines custom-built chess logic, Redis, and WebSockets to deliver a smooth, sub-10ms latency experience right in your browser.

• 🧑‍🤝‍🧑 Instant Peer Connection
  Players can join by simply entering a name and requesting their friend's name — no login or signup needed.

• ⚡ Ultra-low Latency
  Real-time gameplay with <10ms delay using Redis and Socket.IO for state synchronization.

• 🧠 Fully Custom Chess Logic
  All chess rules and piece movements — including check, checkmate, castling, and en passant — are implemented from scratch without external chess libraries.

• 🎨 Interactive Frontend with chessboard.js
  Visual game board using chessboard.js for a polished interface.

• 🗂️ Session Management with Redis
  Player matching, game state management, and messaging handled efficiently through Redis.

• Frontend: HTML, CSS, JavaScript, chessboard.js
• Backend: Node.js
• Real-Time Communication: Socket.IO
• Data Store: Redis

1. Player A registers with a name and enters Player B’s name to request a match.
2. Redis temporarily stores both players' session info.
3. A WebSocket connection is established via Socket.IO once both players are matched.
4. Players exchange moves in real time with minimal latency.
5. Each move triggers a full validation cycle, including:
   • Piece legality
   • King safety (no illegal check-exposing moves)
   • Checkmate and stalemate detection
