Given the [Rules of Chess](https://en.wikipedia.org/wiki/Rules_of_chessThere has been no capture or pawn move in the last fifty moves by each player, if the last move was not a checkmate.
Let the board offer this to either player after its occurrence. Keep it on offer until such time as a pawn moves or a piece is captured (when it will be reset).
