Solution to the 3-mover

The theme in section B was: "The same line is guarded by two black
line-moving pieces (T+T or D+L or D+T). In at least two variations, self
interferences occur on this line, either at Black’s first move or at Black’s
second move."

Solution: 1.Dc7! (2.Dxd6+ Kf7 3.Lxg6#) 1.- Ld4 2.Lg4+ Lf2 3.c4#, 1.-
Lf4 2.c4+ Le5 3.Lg4# (2.- Kxf5 3.Sxd6#)

"The combination of black interference amd self-pins with consecutive
shut-offs makes this the most attractive problem in the tourney, even though
there are only two thematic variations. It was an ingenious idea to have
the black bishop reinforcing the black rooks control of the batteries.
Impeccable construction. A flight is thrown in during one of the thematic
variations, and there is a difficult quiet continuation in the by-play
(1.- g5 2.Sh6 3.Dg7,Dxd6#)."
