Puzzle #2: Mill

  • DifficultyEasy
  • To moveLight
  • TaskMill in 2
  • Main line3 half-moves

Light to move, with 9 light and 9 dark men in the game. Not every man has been placed yet: Light still holds 6, Dark 6.

Your job is to close a mill in at most 2 of your own moves, and it has to work against every defence, including the opponent closing a mill of their own.

What the position is about

  • placement phase — The men are still being set down, so each move places a new piece on an empty point.
  • double threat — The key move creates two threats at once, and one reply cannot stop both.

Finding the way in

Look first for points where you already have two men on a line with the third point empty, then ask which of them the opponent can cover in one move.

Play the position in your head from the opponent's side: what would you do against your favourite move? If there is a good answer, try the next candidate.

Start with d6. Played out against the stiffest resistance, the whole line goes: d6 a7 d7xa7.
