First complete analyze of this 117 new candidates to find dubious key moves :

27) 3rr1k1/1b2nnpp/1p1q1p2/pP1p1P2/P1pP2P1/2N1P1QP/3N1RB1/2R3K1 w - - bm Nf1; id "AlphaZero - Stockfish8";
Qf4 has the same eval as Nf1. May be it's a valid key move also.

31) 4k2b/7P/4KP1P/8/8/pB6/P7/8 w - - bm f7; c0 "eval=mate";
Bd5 is mate in 21 also. Move this position the "special" -> find the mate or a very good eval.

57) 8/2B2k2/6p1/5P1p/6p1/p1p3PP/6P1/1n2K2R w K - bm fxg6+; c0 "eval = draw";
Be5 is a second solution.

72) 8/p7/5k2/pPp1p3/2P3KP/8/8/3Bb3 b - - bm Bxh4;
Bf2 gives the same score.

94) r1br2k1/1p4p1/p1nBp1n1/q5PB/4Np2/2P1Q3/3R4/4K1R1 w - - bm Nf6+;
Qh3 is very good also.

Because this one has too many major pieces:
[d]brkrqbqn/qnpNqqbr/bnNqRbrn/qNrrnRrb/BrqnbqRr/bqRNnprR/QQbNNrNn/bqrnRbKb w - -

I guess that it will cause some programs to crash.
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.

The following positions contain frivolous ep markers:

[d]r4rk1/ppp3pp/3b4/7q/1PPp2b1/P2P1Nn1/3NPRB1/R1B1Q1K1 b - b3
[d]r1b1k1r1/1p2np1p/p1n1pQp1/3p4/3NPP2/P2RB3/2PK2PP/q4B1R w q d6
[d]8/pp3p1k/6pp/7P/P5P1/3K4/1PP5/8 b - a3

Better as:
r4rk1/ppp3pp/3b4/7q/1PPp2b1/P2P1Nn1/3NPRB1/R1B1Q1K1 b - -
r1b1k1r1/1p2np1p/p1n1pQp1/3p4/3NPP2/P2RB3/2PK2PP/q4B1R w q -
8/pp3p1k/6pp/7P/P5P1/3K4/1PP5/8 b - -

So as not to waste database space and effort solving problems that are already solved.
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 guess that it will cause some programs to crash.
It's time to debug this programs ;-)
May be adapt the code to check the position before the search ?
