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.

I'll try Stockfish-dev (unaltered) again. Maybe my first run was unlucky. Or your was very lucky.Dann Corbit wrote: ↑Tue May 05, 2020 10:18 pm Current code seems to solve it fairly quickly, even without altering the null move status.

Re: Any engines good at solving puzzles like this?
At least depht 76 could be some kind of good luck, at my so far only one trial it needed 85 till Nf7 came into pondering as third of 13 moves. Then a long standstill till next output line. But that was with default Contempt of 24, just give it a try with 0 now.zullil wrote: ↑Tue May 05, 2020 10:24 pmI'll try Stockfish-dev (unaltered) again. Maybe my first run was unlucky.

Anyhow latest SF dev. seems to have a problem with giving output- lines in doubt anyhow, at least in Fritz GUI.
Yet Dann is right, SF dev. get's it sooner or later too probably. Might be a matter of hardware and SMP luck, if 10 minutes could be enough or not. Within this time I didn't see it till now.

Re: Any engines good at solving puzzles like this?
I guess this is one of the positions where my little mobility tweak makes a difference.
Here is the version that I used, which reduces null move reductions when mobility is very cramped and increases reductions when mobility has gone wild:
