What "classical chess" means in chess

Classical chess refers to the traditional and most widely played form of the game, where players have a fixed amount of time to make their moves and can only rely on their own memory, calculations, and strategic thinking to determine their moves. It is played on a physical chessboard and does not involve any electronic assistance or timed moves. The standard time control for classical chess is two hours for the first 40 moves, followed by an additional hour for every 20 moves thereafter.
