Dark to move. 14 stones are on the board, 7 dark and 7 light.
Make five in a line within 2 moves. Every move of the solution is a four, so the opponent's answers are forced.
What the position is about
- chain of fours — Each move of the solution makes a four, so every reply is forced.
- open four — The final shape is four in a row with both ends free, which cannot be blocked.
Finding the way in
Find the stone that makes an open four, or a four plus a second four, 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.
