What is Sealed Move?

A Sealed Move in chess refers to a move in the game that is not immediately played on the chessboard, but instead is written on a piece of paper and kept hidden, usually in an envelope. This practice typically occurs when a game is adjourned and the player whose turn is next secretly records their intended move and seals it. The move is then revealed when the game is resumed, ensuring that neither player has an unfair advantage of knowing the other's next move during the interim.
