Sometimes ago, a friend showed me a position where he had the black king removed. The goal was to find where is the black king using some pretty weird reasoning.
I tried to remember the puzzle but I can't. Does anyone know a "where is the black king" puzzle?
There were only a few pieces on the board, quite close to each others in the bottom left corner of the board. Something like 2 pawns each, and and maybe two pieces.
I'm almost sure that the white king was in doublecheck.
Spoiler (more clues but also gives hint about the solution)
The solution (very approximately) was first to find who's move it was, obviously white because of the check, and then from that deduce what was black's last move, and from that deduce the king's position. The reasonning was more complicated than that as it required to go like 2 or 3 step backward but this was the general idea
