This week's problem is another change of genre. In a serieshelpmate, Black
plays a number of moves in a row (in this case, seven), at the end of which,
White mates in one. Black is allowed to capture, but may not give check on any
move except his last. This problem is also a twin. When you have solved the
above position, move the white knight from e5 to f5, and it is again
serieshelpmate in seven.
This is example of Allumwandlung ("all promotions"), all four possible
promotions featuring in the two solutions. Note how the need to avoid a check
early in the sequence forces the uniqueness of move-order.
Any comments or questions on this problem should be addressed to
