Nine men's morris problem #509

The task

To move

Light

Difficulty

Easy

Goal

mill in 2

All men are on the board and the game is in the movement phase: Light has 8, Dark has 8. An easy one: the mill comes on your second turn, so look for a move that makes two threats or forces a reply you can use.

What to look for

• Movement phase: men only step to neighbouring points, so check which of them are actually free.

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.
