Judge: Mikhail Khramtsevich
Henrik Juel: Apparently Gerd has not yet implemented the humble Kangaroo fully, so the beautiful solutions in this problem do not animate (2021-03-22, hidden)
Vaclav Kotesovec: @Henrik, I replaced KA with KÄ and the animation is correct! Kangaroo is implemented correctly. (2021-03-22, hidden)
Henrik Juel: I spoke out of turn, sorry
Now the animation works fine
But it seems that a condition like Maximummmer is missing; otherwise Black is not forced to make in the end (2021-03-22, hidden)
Vaclav Kotesovec: Yes, thank you! Added. (2021-03-22, hidden) more ...
