Is it possible to shade n cells in every row and column of a 2n x 2n grid so that the shaded cells create one contnected region for any n?
@chaotic_iak That's what I thought, but it always seems to "just miss" and I have no idea why.
I came up with this problem a year ago. Sigh.

@Jack_L_Lance@chaotic_iak I'm not sure that it's possible for any n. -
@Jack_L_Lance@chaotic_iak I don't have a proof, though, which is annoying.
