# Searching for a “where is the black king” puzzle?

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?

Edit

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

• Can you give some more clues? Can you remember a fragment of the position? Or some feature of the answer which would make it easier to track down? As it stands your question is too broad. – Brian Towers Jan 17 '19 at 15:15
• You are right, i just did in the edit. I also added a spoiler that may trigger some memory to the ones that have already faced this puzzle, but t does not really give the solution (only partially) – ghilesZ Jan 17 '19 at 15:47

What leaps to mind is Raymond Smullyan's problem, it's to find the white king but possibly it. A retro classic (and one of the few good ones he made.)

``````8/8/8/1r1b4/B7/8/8/3k4 w - - 0 1
``````

(1+3) Where is the white king?

• That's the one! ok its not the black king and there's no double check, but my memory played me some tricks i guess. Thank you very much! – ghilesZ Jan 17 '19 at 20:07
• @ghilesZ: well there was a double check :) – RemcoGerlich Jan 18 '19 at 8:20
• @RemcoGerlich haha yes indeed ;) – ghilesZ Jan 18 '19 at 9:03
