The bubbleman (a piece of my own invention) moves like a queen. It captures by moving infront of a piece. The piece is not taken until after the opponent has moved. the piece cannot be moved, and the bubbleman cannot be captured on that move. in the diagram above, if the bubbleman (represented by an inverted bishop) was to move to the cross at f6, black would have to move his a pawn. then his f pawn would be taken a it would be white's move.
