zChess

An individually developed chess engine for implementing chess algorithms and personal tactic study. zChess is currently in pre-alpha and has yet to have any minor releases yet. It is built purely using Vanilla JavaScript, HTML, and CSS.

Contents

• index.html The landing page for the app
• style.css Basic CSS formatting to display board
• functionality.js The main logic controller
• inputHandler.js The input manager
• an img directory containing the piece images and their respective .psd source files

Features

All chess rules for legal moves are currently implemented in the engine including:

• Check
  • Pieces can't move if it doesn't get their king out of check
  • Discovered attacks that put your own king in check aren't allowed
• Castling
  • Cannot castle if King or any spaces in between are threatening check
• En Passant

Installation

• Clone the repository to your local machine
• Open index.html in your web browser.

Thats it!

Planned updates (In order of precedence)

• Checkmate / Stalemate detection
• Turn system
• Sound effects
• Code refactoring
• Mobile support
• Move King to Rook in order to Castle
  • Note : This is an additional movement option, castling is already possible currently by moving two spaces to either side of the king
• Show potential moves
• AI Opponent
• Engine analysis
• Multiplayer Integration (This may require an engine rebuild)
  • Chat room
  • Matchmaking
