The problem looks as if it could have been taken from a real game. But there is a small inconsistency, first mentioned by Joachim: There are 71 white stones, but only 70 black stones, on the board. This imbalance is aesthetically slightly unsatisfactory, but it would not be easy to eliminate. There is (according to our results) hardly any place to put a black stone on the board, without affecting some key sequences (or their final scores).

White, however, could have taken the 71st black stone at and connected there later. On the basis of this hypothesis Black can win, only if the best sequence for both sides would otherwise end with a win for Black, by at least two points.
