Piece-Drop Mate #1

Here's a second piece-drop mate, but with a twist.

Just like last time, you may only place the maximum number of pieces allowed on the board in a regular game of chess. You're trying to use the minimum amount of material needed(in points).

But this time, you must place pieces so that the position will lead to a mate next move, not an immediate mate. Also, there are NO PROMOTIONS allowed. Good luck! ;)

Opening bid: 6 points. Bishop on b7, knight on d7. Black is forced to play Ka7, then White can play b6#.

Real answer (thanks @Sid!)

Bishop on b7, pawn on c7. Black is forced to play Ka7, then White can play b6#.

    $\begingroup$ Bishop on b7 and pawn on c7 should also do the trick, no? $\endgroup$ – Sid Jul 27 '19 at 19:21
  • $\begingroup$ @Sid You should have answered that yourself! Fixed. $\endgroup$ – Purple P Jul 27 '19 at 20:03

This is probably bending the rules, but....

1 point or 2 points (see below)

As follows:

put a white pawn on d7. Put a black pawn on a6. I'll assume this point doesn't count against white, but even if it does, it makes the solution 2 points. Then, bxa6+ followed by Qb7#

  • $\begingroup$ doesn't work; has to be a 1 move mate. $\endgroup$ – MakeHellTal Jul 27 '19 at 21:31

    $\begingroup$ @MakeHellTal Well, it says mate on next move, but doesn't specify if it's currently white or black's move. If it's whites move then it would be mate on next move! $\endgroup$ – SteveV Jul 27 '19 at 21:40
  • $\begingroup$ Correct, I overlooked that $\endgroup$ – MakeHellTal Jul 27 '19 at 21:43

I can do it in 3 points:

Place pawns on b7, a7, and a6.

  • $\begingroup$ @I N T E R E S T I N G Kxa7 and how do you plan to mate Black in 1? $\endgroup$ – MakeHellTal Jul 27 '19 at 17:50
  • $\begingroup$ Plus, that places 10 pawns on board, exceeding the limit of 8. $\endgroup$ – MakeHellTal Jul 27 '19 at 17:51
  • $\begingroup$ @MakeHellTal - Ohhh.... I completely forgot about that. Oops! $\endgroup$ – Voldemort's Wrath Jul 27 '19 at 17:51
  • $\begingroup$ @MakeHellTal - I misunderstood the direction... Oops! $\endgroup$ – Voldemort's Wrath Jul 27 '19 at 17:51
