Piece-Drop Mate

Question

Find a way to checkmate Black by placing pieces!

You must use as little material as you can(in points). You cannot place more pieces than allowed in a regular game of chess!

Good luck! :)

7

I can do it with

6 points

As follows

2 knights. One knight must be at either c5 or g5, guarding the bishop and the e6 square. The other knight must check[mate] the king. So at d7 works.

$\begingroup$ You can prove optimality by showing a single rook clearly cannot check the king AND protect the bishop, 3 and below points trivially does not work, and 4 points does not provide enough material :) $\endgroup$ – im_so_meta_even_this_acronym Jul 27 '19 at 2:37
$\begingroup$ By the way the knight could go anywhere legal, not just d7. $\endgroup$ – MakeHellTal Jul 27 '19 at 17:11

$\begingroup$ @MakeHellTal (I like the name!) yes, I meant that d7 worked, but so do 7 other spots. $\endgroup$ – SteveV Jul 27 '19 at 17:25
