The objective of the project:
The objective of our Online Chess Game project is to create an online Chess game that enables you to both play with your friends as well as against the computer.
Chess Game Rules:
- The player with white pieces starts his turn first.
- The Player has to protect his king and subsequently make strategies to kill the opponent’s king.
- When the king of one player is checked by the other player’s pieces, he will have to take the king out of that check to a safe place. The player who checks the king has to warn the opponent by saying “CHECK”.
- The one to lose his king will be the one to lose the game.
Features:
Player vs Computer:
The player will have to start with whites and make her first move, and the computer will take blacks.
Player vs Player:
The player who takes whites should start first and the other player plays alternately.
