And WD on 8x8 can be tried here. It doesn't seem to have much difficulty forcing checkmate against any play, even though it starts in a generally unfavorable position (with the strong side crammed in a corner.) For a piece like WD it could be worse if it starts in the corner opposite from its own King; then there are positions where it is 'dynamically trapped', when it is on the same diagonal as the bare King.
