I had that idea, but even with that, I'm still stuck. I get to a position with white king stuck behind the pawn on c3, with black pieces on a5, a6 and d6.

Or I start with dxe, take the white rook with the pawn, and end up with black pawn on a1 and white bishop on e6.

Another hint?

EDIT Oh never mind, finally got there. Just a slight tweak to the move order, which took forever to discover.
