The shading pattern must be symmetric with respect to the two diagonals.
Otherwise standard Sudoku rules apply.
Solution code: row 9

Another really nice puzzle with a great flow. I like the ones where we have to shade them ourselves. Thanks for creating it.
---I think the to-shade puzzles add something though I personally like the relative purity of the given-shading puzzles (a point of view not necessarily shaded by other solvers).
Thanks for your solve and the kind comment. ---ATK

It's possible that I will be without the internet for a few days, so forgive me if I fail to reply in a timely fashion to any comments.
