A bishop stuck in the corner like that can only give check via discovery, of course.
Don't you need to move everything across 1 square: bishop on b1, pawn on f6 and king on g6?

Moving the pieces one square to the right gives several possible last moves. Ba2 could have captured almost any piece on b1, giving check.

Originally posted by BigDoggProblemwell you posted the correct position right away. not much there to add then 😉
The last moves in my solution were -1.dxe6ep e7-e5 -2.d4-d5+. I'm surprised no one got this.
i knew this one from a book. white king is on d7 and author is N. Hoeg, Skakbladet 1916 🙂
