The white King has disguised himself as another piece (or pawn) of indeterminate color. Where is he?

Originally posted by SwissGambitsince the position is a checkmate and there is no legal way that the white Queen had come to that position without a previous checkmate, but the Queen can`t be the white King since then the position would be illegal I think the white King is the black King who in turn is disguised.

Last move must have been Qg8 (not possible) or g8=Q (not possible)
therefore the black king is an imposter and is really the white king
but that's too easy!!!!
Are you sure board is correct SG?

Originally posted by tvochessWell done. wK is on c7 because that reduces the number of black pawn captures by one. We don't know for sure that Bc1 was captured on b6 (it could also have been the promoted d-pawn).
Next step in the solution:
The white king is disguised as the black pawn on c7.
SPOILER ALERT!
Explanation:
Assuming all black's pawns are genuine, the following moves must have happened at some time during the game: b7xa6, d7xc6 and c6xb5. On the other hand, white has only lost 3 pieces: 1 pawn, the dark-squared bishop and 1 rook. Each of the c ...[text shortened]... came from c7 by capturing the dark-squared bishop on b6 and then moving one step forward to b5.
Originally posted by tvochessYes, that's what I mean. Bc1 can be captured by something else.
hey SwissGambit,
I'm happy that my solution was correct. However, I don't understand your last comment. If Bc1 wasn't captured on b6, where else was it captured? I'm unsure, but do you mean that this bishop may have been captured by something else than a pawn?
By the way, nice puzzle!
