The following position was reached via a sequence of legal moves from the starting position. Black made the last move. What was that move?
Give a complete description of the move, including departure square and piece captured, if any.
If there is more than one answer, give all possible answers.
Adhere strictly to the letter of 14D. If the position immediately prior to the diagrammed position had been a dead position, then the diagrammed position would not have had an opportunity to arise, because under 14D the game ends immediately when a dead position is reached.
A dead position is one in which there is no sequence of legal moves leading to either player being checkmated, even if the players cooperate in trying to find such a sequence.
It look like the possibilities are Kf8xB (instead of Ke8), Kh8xR (instead of KxN) or Kf8xN (the last is not technically dead though the king starting on h8 would be a dead position due to the forced capture)
A) Nh7+ Kf8xBg8
Throughout all of this (and the other thread) I have been looking for some kind of position where the previous move could have been KxR but not KxQ (because the latter would have been forced but not the former) and where KxB, KxN, and K moves without capturing are all impossible for (possibly) other reasons. I haven’t succeeded yet. The current problem would be such a position if you could somehow prove that the king came from h8 rather than f8. Does anybody have any ideas for improvements?
