Sting also solved it. I won't show the analysis here because (for some strange reason) Sting 20 only used 2 or 3 threads out of the 32 I alloted. I think it is a quirk with Arena because I see this happen a lot.

Crystal was at three trials with 24 threads of 3x12GHz CPU and 32G hash rather variable in time to solution, from <1 minute to > 5, in MV2 much faster.
Most engines I tried have a6 second best in 2MV almost at once, yet then taking some time to get it up with winning eval, all except Crystal, which was at all trials almost at once stable on a6 as best move in 2MV mode.

Here's a komodo- setting with King Safety 200 (84 def.) Dynamism 200 (def. 120) and White Contempt 50 (def. Contempt 16, Analysis Contempt off)

Best of three trials:

Second best was 24", worst one more then 5 minutes.
For rather sure, that won't be the best setting with lowest (best playable) change of parameters, should rather fiddle with Selectivity and Reducionts a litte too maybe.
Another one single try with Selectiviy 100 (def. 170), Reductions -100 (def. -30)

OK, thank you Louis. For some strange reason Stockfish doesn't find it on my computer (must be the dumb luck MP thing)
Actually, I see what you mean. Here's my second search with Stockfish:

Finally found it ... maybe:

Sting also solved it. I won't show the analysis here because (for some strange reason) Sting 20 only used 2 or 3 threads out of the 32 I alloted. I think it is a quirk with Arena because I see this happen a lot.

Yeah, I mentioned in the original post that Crystal and Sting and Komodo all found it, and just like your Crystal run mine solved it in seconds the first 2 or 3 times, however I tried Crystal again in three new runs of 10 minutes + and it only gets it now sometimes and sometimes not.

first run more than 10 minutes (doesn't get it):

Crystal seems to be hit or miss for me. The only one that seems to get it quickly and every time is Sting (at least for me)

Leela almost immediately detect a6. Meanwhile stockfish is stuck at triple zero until later in the game.

Surprisingly Stockfish is unable to see advantage.

...but leaves it for Bb8 instead now and then again with longer pondering, because the eval doesn't become a clearly winning one.
Tried different nets including LS 13.1 and Fat Fritz, all with 2x2080 RTX.

Try Crystal in 2MV- mode, if you like too.

Please forgive my ignorance Peter, but what exactly is 2MV- mode? is it PV=2? or is it something else entirely?

Sorry, put the blame on me, 2MV to me means, as you presume quite right, multi variant with two primary lines.

There's no blame my friend, I'm not here regularly so I might not be familiar with the terminology as everyone else here is, as you pointed out though many engines have 1.a6 as their second choice so that kind of defeats the purpose of a test position in my VERY humble opinion. That might be one of those "dirty tricks" that Marek (the author of Sting as I'm sure you already knew) was talking about in his post about Sting-sf-20

One might see the trick as dirty, but it helps in very many positions. Pruning- parameters are just not the same in primary lines as they are in non primaries, as you'll probably know. If only two lines of multi variant pondering are necessary, that doesn't even cost much time to depth, so I'll give it a try now and then in almost all postions of interest. Pity it doesn't help NN- engines as much as it does for A-B-ones as for my personal point of view.

Crystal at single variant in this very special one gets it, as you pointed out, sometimes very quickly, sometimes it takes much more time. With 2 primary lines it's at the top with clearly winning eval at once every single try, I had till now.

Thanks for bringing this one up again, btw. Peter Krug is an Austrian composer, not a German one, I know him since quite a while, not personally but from some mails we had and of course from German CSS- forum too. Haven't heard his news for quite a while, hope, he's well.
