Solution?

Where can the solution be found? Viktor Allis is uncontactable.

Answer: Solutions were found by Computer, so it's hard to show you all positions. But you can trust this because there must be at least 10000 players around the world, who can prove a surewin on board-size 15x15 and bigger. I think there's a surewin on 13x13 too, but nobody would take time to prove it, because it's not interesting. Smaller board sizes would reduce the branch-factor and therefor less complex.
