Which doesn't mean for sure, that there couldn't be further ones, I checked only those, that Huntsman doesn't solve within 5" with 30 threads.
As for my personal use, I replace these 13 with #10- positions, filling a suite up to 555 positions all in all, which then gives a reasonable hardware- time to let it run about 5"/position, regards
Huntsman is excellent solver. I tried last 1000 positions and gave it 6 cores and 3 seconds. It found "bm" in 944 positions. For comparison SF17 got 786 solutions.
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.
You're welcome, Dann!
Here are the 555 out of #10, #11 and #12 I like to use as a smaller sample, those not solved by Huntsman in 5" with 30 threads checked as for single best move:

At the mentioned hardware- TC Huntsman 1.0 solves 542/555 (Fritz19- GUI: 542 aus 555 = 97.6%. Durchschnittszeit = 0.12s / 11.79), so for this one engine better <5", e.g. as Jouni writes 3" SMP or less, but then other one engines get too much discrimination again, as with all suites it's a matter of engine- pool to compare with, regards
Thanks for the 555 position thinned set. I was planning to do something like that myself.
It would be interesting to see how various strong solvers do on that set.
I am doing a huge gambit analysis right now, but when that is done I may give it a go.
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.
Well, here's a first little EloStatTS- list out of three engines, Huntsman and SF dev. with 30 threads, 1G hash., Lc0 with 3070ti GPU and 1G NN- cache, net 6147500, all with 3"/pos. SF and Lc0 using 6men Syzygys (which rather costs SF a few solutions probably but helps, yet Lc0, I guess, does better with them), Huntsman with ProbeLimit=0:
It appears to me:
The stockfish from 2024-05-18T09:18:14+02:00 is the best mate solver. The power of SF to solve mates has been plunging precipitously lately (according to the graph).

Note, that test is with fixed nodes. Not good way to test at all. So SF11 before NNUEis really the fastest mate finder!
Correct under the terms given abvove (30 threads, 3"/pos, 6men Syzygys for all except Huntsman) for the engines and settings I tried so far, not counting Huntsman, SF 11 was 509/555 at a single run of mine.
BTW, had a bug in the suite yet still, position nr. 3 is stored twice, it (or nr. 4=) has to be replaced, sorry for not noticing till now
