Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

One of the maybe records got goofed up. It should be:
bm Bf2; ce 32740; pv Bf2 Qxf1 bxc2+ Ka1 Bd4 Qf4 Bg7 Nf2 Bh8 h5 Bg7 h6 Bh8 h7 a6 h4 a5 h5 a4 h6 a3 Qf6+ Bxf6 Ne4+ Kd3+ Nxf6 c1=Q+;

Suggesting eliminating criteria: Those positions with 7men on the board or less. Rationale: These can be solved by a TB lookup without an engine.

I've also cleaned up one of the new candidates, eliminations at the end of this post.

I also saw a mirror in one of the positions (the one I just posted has a colors reversed twin)
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

I am doing another search for alternate solutions now, also.

And this is the theme duplicate (both of these can be found in the ChestUCI EPD database):

bm Bf7;

This one is easier, so it is eliminated:

After sifting through 1000 potential positions, I came up with these additional candiates:

Give the previous 47, the total is 47+22=79
So if we eliminate the 15 least desirable positions, that gives 64 (the goal count, IIRC).
Previous best + remaining candidates:
