I'm also updating the parameters for wider search because I'm doing very long calculations and I'm using SF to guide LC0 if there are tactical problems. I will be recompiling LC0 to use doubles instead of floats like koedem has suggested - this seems more important in long searches.

h4 is likely next.
I'm curious how deep your SF searches are vice your Lco searches.

I'm very interested in the response. I've stayed with a larger net based on LC0 Discord recommendations.

I'm using Nibbler for LC0 lately and it doesn't show depth. I'm usually just verifying various LC0 lines in SF but if I run a full long search, it gets to around 51.

Komodo 13.2.5 at depth 45 using MultiPV=3: Black's three best options have evaluations of -1.19, -1.12 and -1.11. Won't give the associated moves!

So was that mystery move h4?

This is where it gets interesting -- when move evals are very close. Generally, it could mean the engine doesn't know what to do (or it could mean the moves really are much the same).

Yes. And I didn't check if the three PVs include transpositions and might converge to a common future position ...

From what I've seen, the lines in this game do not converge (order matters a lot).
