15 10?/26?

In the actual battle, White played 10. Compared with 26, he only played roughly 140 games.
With 10 moves, the winning rate is 86%, with 26 moves, the winning rate is 78%, and the draw rate is high, 7%.
It can be approximated that walking 10 is no problem

        21, 23,
        19, 20,
        17, 18,

If Black is placed at 31 or 15 in the upper left corner, the winning rate is 70%, and if White is placed at the bottom or the right vertical position of 10, 26, 12, 28, the winning rate is 35%. The other moves have low win rates.

After Black puts 31 or 15, can White have a solution?

depth: White's 4th move depth is increased to 18, resulting in a very slow 4th move
