Piece-Drop Mate

Piece-drop Mate #2

Piece-drop Mate #3

Here's another installation of the Piece-drop Mate series!

I'll try to be more explicit about the rules of the puzzle, as recommended by @Rewan Demontay.

This time, the position is one where Black wins. He makes a regular move and places a piece on the board at the same time, resulting in a position in which White is checkmated. White never gets the chance to make a move in this puzzle.

As usual, everything about the position must be legal (except for the fact that you are making a move and placing a piece at the same time, of course) (i.e. the position can't have more than 8 pawns at any given moment.)

Good luck!


@Rewan Demontay was such a stickler about the legality of this that I have to include the fact that position can only arise from a Chess960 position due to the bishop on e8.

    $\begingroup$ It's hard to require a legal position of the position that you have is illegal-The black bishop on e8 couldn't possibly get there, but I suppose that you could call it a Chess 960 game for some salvation. $\endgroup$ Jul 28, 2019 at 0:01

    $\begingroup$ Even Chess960 doesn't save the impossible pawn structures from earlier puzzles. $\endgroup$ Jul 28, 2019 at 0:15

The move is d5. Knight on c8 is the placed piece, giving 3 points.

  • $\begingroup$ Correct! Well done! $\endgroup$ Jul 28, 2019 at 0:04
  • $\begingroup$ Can anyone post an answer with all 3 moves? $\endgroup$ Jul 28, 2019 at 0:04
  • $\begingroup$ Obviously, there are a variety of different answers here. One can place a knight on a8 or c8, or a bishop on c7 or a7. $\endgroup$

5 points:

Rook at b4

6 points:

Knights at d4 and b2

9 points:

Queen at b4

Obviously this is not an optimal solution and shall be expanded upon later...

  • $\begingroup$ Yeah your rook answer might be the best placing-only solution. $\endgroup$ Jul 27, 2019 at 23:58
  • $\begingroup$ @JoshuaBizley - Yeah, you could just move a random pawn to add a move to it, though... $\endgroup$ Jul 27, 2019 at 23:58
