Puzzle #26: Mill

  • DifficultyMedium
  • To moveLight
  • TaskMill in 3
  • Main line5 half-moves

Light to move, with 8 light and 9 dark men in the game. Not every man has been placed yet: Light still holds 5, Dark 5.

Your job is to close a mill in at most 3 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.
  • counter-mill — The defender can close a mill too and will take a man; the solution still works after that hit.

Finding the way in

Three-move mills usually need a quiet first move that builds two separate threats; check what the opponent can close in reply before you commit.

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 d7. Played out against the stiffest resistance, the whole line goes: d7 f4xd7 d7 a7 d6xa7.
