Quah examined the use of fairy pieces to show triple Grimshaws in two movers, Ruud
Beugelsdijk investigated shifts of moves motivated by twinning involving a change of
condition, and Bob Meadley and Geoff Foster contributed a biographical article about the
Latvian born Australian composer Laimons Mangalis. Ian Watson reported on the European
Solving Championship and Browsing in the Library covered the 1919 treatise on
mutates, All Change Here! The Supplement featured articles by David Shire on
two-movers featuring critical play, and John Rice on the work of helpmate expert Fadil

Nightriders play one or more knight moves along a straight line as a single move,
i.e. Nh1 can move to f2, d3, b4, or capture on g3, while Na2 can move to c1,
b4, c6, d8, c3, or capture on e4.

Three black pieces control the white battery. Each piece in moving to f2 shuts off the other
two, and in turn is shut off by the rook.
