What "correspondence chess" means in chess

Correspondence chess is a form of chess where the players do not play in real-time but instead make their moves via some form of communication such as mail, email, or online platforms. Each player has an agreed time limit to make their move and send it to their opponent. The opponent then responds with their move, and so on until the game is complete. This form of chess allows players to take their time to analyze the game, research strategies and use computer analysis to help them make their moves. It is often used for international competitions and is a popular way to play for those who prefer a more leisurely approach to the game.
