Solution

13-9!---E 26-22---A,B,C 9-6 22x13 19-16 2x9 11-7 12x19 7x16 Drawn.

A---If 18-22 then 17-13 10-14 11-15 26-31 9-6 2x9 13x6 31x24 15-10 24x15 10x26 Drawn.

B---If 26-23 then 11-15 23x16 15x22 16-11 9-5 etc. Drawn.

C---If 26-31 then 19-16! 31x24---D 28x19 10-15 19x10 12x19 Drawn.

D---12-19 actually loses here after 11-16 31x24 16x7 2x11 28x19 White Wins.

E---Other moves simply don't work, for instance 11-15 is a blunder and loses at once to 25-31 15-22 31-15. Another losing try is 28-24 26-22 11-8 10-14 17x10 18-23 27x18 22x6 8-11 20x27 Black Wins.
