A reflexmate is a chess problem in which White, moving first, must force Black to deliver checkmate within a specified number of moves against their will – with the added condition that if either player can give checkmate, they must. If this condition applies only to Black, it is a semi-reflexmate. (Without this condition, the problem is just ordinary selfmate.)
