FWIW, Crystal doesn't LMP the PV, so one might expect results similar to Komodo.

Do these stockfish's really know the position is drawn, or do they just have some hacked eval modification that equates a lack of progress to a draw.

Surely, a search based result is more reliable than eval.

Ok, I was able to track down the issue with the Rc1 position and fix the regression there. The second position I consider more or less resolved as well. When fed the position after Kh8, it properly detects the queen stalemate and eventually switches over to promoting to rook. This takes a little bit...

I don't think so? For a second I thought I must have missed something, but playing through alternate lines.... Again, I see no reason for promoting to a queen to be a draw. EDIT: OK, I found it.

I hope You have looked at Houdini 6 tactical mode source. It solves some tactics still faster than Crystal even being from 2017! To be honest, I doubt I will. While the code is GPL, it was undoubtedly not intended to be public, and I have no way of knowing if all of the ideas present are genuinely ...

Thanks for the kind words. I don't really have the setup to provide high quality cross compiles... But I wouldn't bother with the minor updates for now. I'm still actively working on it and SF dev is going at a rapid pace. Once things slow down a bit and I am confident I have everything I want in fo...

Better contact Microsoft/Github while you are at it....
