Light to move on the 5 × 5 board. 32 of 60 lines are drawn, Dark has 0 boxes and Light 1.
24 boxes are still unclaimed. With best play you can take 18 of them, 12 more than the opponent gets, and exactly one line achieves that.
What the position is about
- keep control — With best play you stay in control and collect more than half of what is left.
Finding the way in
On 5×5 the chains are long and the loops expensive. Work out the value of opening each component, and open the cheapest one for the opponent to take.
Before you touch a piece, list every forcing move you have and every threat the opponent has; the answer is almost always on that short list.
