Um, this is a weird one. I was using Crystal 2.0 on this...
[d]5K2/2p3p1/Q2r2P1/3P4/1P5B/7p/pp4pr/kn4Rb w - - 0 1
which the list had as a mate in 17. C2.0 found the mate after a couple of minutes, but I was away from the computer and didn't check back for a couple of hours. Here is what it reported (output from Arena)...

Could someone verify the M13. Not sure if it is a glitch or a TT issue since my 16Gb of hash maxed out.
I will also start it on another engine just to verify.

It seems ok to me. Not easy to check, a lot of complex variations to check with Crystal.
5 best moves after 1.Qc4 gives distance to mate but 3 moves are longer than mate 12.
I checked this 3 subvariations (Rc6, c5 and c6) and they are all shorter or equal to #12.

It's very interesting to see how this shortest mate is hard to solve.

Wow, thanks for the help.
I should have tried Chest, but I rarely do for really deep mates.
Maybe I leaned a lesson.

If the position is a complete unknown, what are the best settings in ChestUCI to minimize the time to solve? Specifically, the "SearchMethod" setting.

I don't know. Most of time when I used chest it is for short mates (dm 8 or less) and I use chest319.
When I use the UCI version, I generally use autoturbo. But I guess that there are better settings.
I find that reading the instructions leaves me more confused than before I started.
I have tried using database mode, but that only looks up the database value and does not compute anything.
I have found that the behavior changes a lot when you change maximum depth of search. I have no idea why.

[MikeGL]

Thanks for the solutions posted.
Could be a cook due to many alternative quick mates.
Yes i agree with your line, maybe your mate in 17 solution was the intended solution by the composer
with B promotions twice:

Here is one from your unsolved file.
[d]5N2/5p2/BBpNpK2/P2kP3/2p2P2/2p5/2pPbPP1/2r3nn w - -
It has two solutions, neither which is the published move of (d3). Once H6 figured out there were 2 solutions, I started it again with MPV=3 to make sure it wasn't a triple.
Very tough even to find one mate for most engines.
