Dark to move. There are 13 dark and 31 light discs on the board and 20 empty squares.
Force your way onto a corner square within 2 moves. The opponent sees it coming and will defend.
What the position is about
- corner — The fight is about a corner square: once taken, it can never be flipped back.
- edge square — The key move is on the edge of the board, where discs are harder to flip.
Finding the way in
Look for a move that leaves the opponent only replies that open a corner for you, or a disc that, once flipped, gives you a diagonal into the corner.
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.
