The selfmate is forced by means of Zugzwang: The only contact move that does not expose the black King gives a fatal check. Threefold exact echo mates, achieved without any repeated moves throughout the three solutions. (Author)
Koko (Contact Chess): A move is legal only if at least one of the squares adjacent to the arrival square is occupied (i.e. a piece, having moved, must be in contact with another). This applies also to the Kings: A King is not in check, if his capture leaves the capturing piece isolated. |
