No.841 by Peter Harris – Author’s favorite Ultra-Patrol condition in a four-men with an exotic content! Thank you, Peter, for a nice dedication! (JV)


Ultra-Patrol Chess: A piece can move, capture or give check only if it is observed by a piece of its own side.

Sentinels Pion Advers: 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.

Royal Piece: Piece that executes a function of the King on the board.
