What was black's first queen move?
Try solving without actually moving the pieces - just by studying the position.
Bonus question: without the e8 knight the problem is cooked. Why?
Bonus: e3xf4 is possible w/o Ne8 on the board.

how the Knight got to a1?
it must have been there before the Queened pawn,because it has to have moved from b3 or c2. Both are blocked now by pawns; one that must have been released from the a-file by a capture.
So before the a-pawn got to the end, the capture must have occured, meaning the Knight must have got there before this, becasue it is when the blocking of b3 occured and closed it's way in. How does it work?
EDIT: Does that make sense?
