Chess

Overview

This project is a simplified chess game implemented in Python. It allows two players to compete against each other by following the core rules of chess, with a few exceptions for simplicity. The focus is on piece movement, capturing the king, and turn-based gameplay rather than the full complexity of check and checkmate.

Features

• User registration and login system
• Ability to start a new game with another registered user
• Pieces move according to the standard chess rules (except castling, en passant, and pawn promotion)
• Simple board display in text format
• Option to select and deselect pieces
• Undo functionality (each player can undo up to two moves per game)
• Configurable move limit (or unlimited if set to 0)
• Forfeit option if a player wants to give up

Installation

Clone the repository and move into the project directory:

git clone https://github.com/soroushsohrabi/Chess.git
cd Chess

This project only relies on Python's standard library. No external dependencies are required.
Make sure you are running Python 3.8 or later.

Run the game with:

python Chess.py

How to Play

The game is entirely command-driven. Here are the main commands:

• register [username] [password] → create a new account
• login [username] [password] → log in with your account
• new_game [username] [limit] → start a game with another user, limit = number of moves allowed (0 = unlimited)
• select [x],[y] → select a piece at given coordinates
• move [x],[y] → move the selected piece to a new spot
• next_turn → finish your move and pass the turn to the opponent
• undo → revert your last move (max 2 per player)
• show_board → print the current board state
• forfeit → give up the game
• logout → log out of your account
• exit → close the program

Game Rules

• The game ends when a king is captured.
• Check and checkmate are not part of this version.
• Pawn rules: can move one or two squares forward on their first move, afterwards only one. Capturing is diagonal.
• Bishop moves diagonally, rook moves horizontally/vertically, queen moves like both, knight moves in an "L" shape and can jump over pieces, king moves one square in any direction.
• No castling, no en passant, and no pawn promotion.
• If the move limit (set at game start) is reached, the game ends in a draw.
