Checkmate as time expires

  • 5 years ago · Quote · #1


    This almost happened to me recently and it got me to thinking - What would happen if checkmate and time expiring for the player delivering mate happened at exactly the same moment? Is there an official rule on this?

    If not, I sure wouldn't want to be an official monitoring the game and having to make the call.

    I'd imagine that if it was really that close then it would be a draw.

    The instant the checkmate move is completed - ie when the piece is released, the game is ended with checkmate even if the flag drops. If the flag falls before the move is completed then it is a loss on time.  Both events would have to occur at exactly the same moment of time for there to be a problem. In practice the checkmate is there to see on the board while the flag fall isnt - the rule states that the flag is deemed to have fallen when it is seen to have fallen by the opponent or arbiter. I dont see in practice how a flag fall and releasing a piece can be seen to occur at exactly the same moment in time. Either the players would agree a draw or, if an arbiter was asked he would go with the checkmate

    If the flag has fallen before the checkmate move is made but opponent haven't pointed that out then checkmate is valid. If the opponent points out that your time is up before you have made your move to checkmate then it's loss (or draw if there is no material enough). My inner lawyer is wondering that when you touch your piece it is considered a move then if I have picked up a piece and my opponent shouts:"TIME!" can I complete my move that is considered alrealy made and win the game if it's checkmate after that.

    This move is considered to be made when you touch your piece comes from the rules where opponent makes a wrong move. Chess rules say that you have rigth to point out wrong move before you have made your own next move and touching a piece is considered as will to complete move and counts as move. So you have to point out that your opponent has made wrong move before you touch any piece.
