Puzzle #24: Mill

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

Dark to move, with 9 light and 9 dark men in the game. Not every man has been placed yet: Light still holds 6, Dark 7.

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.

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.

Take your time. There is no clock on the result, and a wrong move is simply taken back so you can look again.

Start with a4. Played out against the stiffest resistance, the whole line goes: a4 b4 a1 a7 g1xa7.
