Correspondence chess is like playing chess with a friend who lives far away. Instead of sitting next to each other and making moves on a physical chessboard, you play by sending messages or letters to each other with your moves. This can be done through the mail, email, or even online platforms.
The game can take a long time to finish because it can take days or even weeks for each player to receive and respond to their opponent's move. This means that players have more time to think about their moves and make strategic decisions.
Once a player makes their move, they send it to their opponent, who then decides on their next move and sends it back. This cycle continues until the game is over.
Something special about correspondence chess is that players can use chess books or other resources to help them think about their moves. It's also a great way to meet other chess players from all over the world and improve your game by playing against stronger opponents.
