White just made a move, but then realized there was a mate in 1 on the last move and missed it. What was white’s last move, and what was the mate in 1?
White’s last move was to capture a piece on e8. What piece was it? There is only one possibility that allows white to checkmate.
Take back 1. d7xNe8=Q and instead play 1. d8N#

Tricky. My guess was that the white queen was b8 and the right move was b3 but it could get blocked by the black queen for checkmate in 2.
