Some positions on Ed's Start Your Engines were showing Stockfish blind at depth 120... (with a mate in X on the board, Stockfish was showing 0.00 at such depths...)
Great spirits have always encountered violent opposition from mediocre minds.

I tested MateFinder 9 Ipman compile and it's better than 2017 versions.
Here's mate in 15 from Chest database
[D]K4b2/B3p1p1/p2pP1p1/P1pN2N1/1pPk1P2/1p6/1P6/5B2 w - - bm #15; 00:00 @ C2/R0/K3/P1/X2;

MF finds it fast, but improves soon to mate in 10! Hope this wasn't prize winning composition :) .

24/30 00:04 48 515k 10 274k +M15 Ng5-f3+ Kd4-e4 Nf3-d2+ Ke4-d4 Nd2xb3+ Kd4-e4 Nb3-d2+ Ke4-d4 Nd2-f3+ Kd4-e4 Nf3-g5+ Ke4-d4 Ba7-b8 b4-b3 Ng5-f3+ Kd4-e4 Nf3-d2+ Ke4-d4 Nd2xb3+ Kd4-e4 Nb3-d2+ Ke4-d4 Nd2-f3+ Kd4-e4 Nf3-g5+ Ke4-d4 b2-b4 c5xb4 Bb8-a7+
25/30 00:06 62 899k 10 129k +M10 Ba7xc5+ d6xc5 Ng5-f3+ Kd4-e4 Nf3-e5 Ke4-f5 Bf1-d3+ Kf5xe6 Bd3xg6 Ke6-d6 Ka8-b7 e7-e6 Nd5-b6 Kd6-e7 Kb7-c7 Ke7-f6 Nb6-d7+ Kf6-e7 Ne5-c6+

If MF finds shorter mate it's correct!

I guess you have a quite old version of the ChestUCI database, because this position has been corrected already long time ago (to #10):

K4b2/B3p1p1/p2pP1p1/P1pN2N1/1pPk1P2/1p6/1P6/5B2 w - - bm #10; 00:00 @ C2/R7/K3/P2/X3;
