* The side having this piece is in check if it is threatened.

** A Fers is a fairy chess that moves like a Bishop, but can only go one square.

*** A piece cannot capture or check (but may move or observe) if it is not observed by another piece of its own side.

**** When a piece (not a Pawn) moves, a Pawn of the colour of the opposite side appears on the vacated square, if it is not on the first or the last rank, and if there are less than 8 Pawns of that colour on the board.
