Draughts problem #527

The task

To move

Light

Difficulty

Hard

Goal

win in 5

On the board: 2 men and 0 kings for Dark, 1 men and 1 kings for Light. A long forcing line of four or five moves. Kings and tempo count more than material here.

What to look for

• A sacrifice: giving material first is the only way to force the result.
• Kings are on the board and their freedom to move backwards matters.

How the answer is checked

There is exactly one first move that forces the result; any other first move allows the defence to escape. Moves that keep the forced result are accepted later in the line, and a move that loses it is taken back with a short note.
