This is a quote from, of all places, a Hex Wiki: https://www.hexwiki.net/index.php/Games_from_the_13th_Little_Golem_TwixtPP_Championship I just added the vertical bar.
"György: |9.h11 was a mistake, because 10.j11 connects black to the left, and shows strength towards the right. After that it was an uphill battle for spd_iv. But he played it really smartly, used every chance he had. 13.o10 was a very good move, just like 15.s10. It was a tough fight, perhaps the most difficult for me at this tournament. Unfortunately for him, he was too much behind, so I clinched victory with 26.r16."

Maybe |9.g12 was better? 10.j11 11.f10 12.g8 13.g7 14.f6 15.f5 or 14.i7 15.e8 16.g6 17.c3 18.c5 19.d5 or 12.g6 13.f7 14.e7 15.i8 16.j5 17.r8 18.j15 19.q15 20.q11 21.j16 22.k7 23.o11 24.p13 25.k14 26.o10 27.m7 28.m11 29.k8 30.i9 31.h10 of course this barely scratches the surface, and I could easily have missed something.
|9.g12 10.j11 11.f10 12.g6 13.f7 14.e7 15.i8 16.j5 17.r8 18.j15 19.q15 20.q11 21.j16 22.k7 23.o11 24.p13 25.k14 26.o10 27.m7 28.m11 29.k8 30.h10
Leads probably to this 31.d8 32.j9 33.c6 34.c2
