Mika Korhonen, 1983

Helpmate in six moves (two solutions)

First solution: 1.Kb1 b4 2.Kc1 b5 3.Kd1 b6 4.c1Q b7 5.Qc4 b8Q 6.Qe2 Qb1 mate.

Second solution: 1.d1B b4 2.c1R b5 3.Rc2 b6 4.Bg4 b7 5.Bc8! bxc8Q 6.Ra2 Qc1 mate.

Note both solutions have different and distinctive final mates. And in both solutions the order of moves is unique. In no case can either side deviate from the one and only path to mate.
