Pos 11:
[d]8/5K2/3p3p/3p3P/pp1P4/rkb1R3/p1p3P1/n1B2B2 w - - bm Rd3; dm 16; id "je 11"; c0 "e3d3";
Pos 11 seems too hard but becomes easy if you give the first move Rd3. So that is probably only solvable without nullmove in the critical line.
Given processing power and time, there is nothing impossible for SF.
I will give Deuterium a long time, just interested if it can find the bm.

:) Thanks for trying that with big brother SF Louis! Yes, tactical positions can be very random. And testing with one thread is in my opion not really a solution, because then you get one basically random result, one draw out of the pool, the time would be different if you change the source with something insignificant.

But I admit, the search of RS is now a bit more singular extension driven and I tried to push it a little further. Basically what that means is that you try to reduce everything unless it is singular, or check, maybe passed pawns, the things SF extends always. It is just an experiment. You have no control over nullmove with this, because that is a separate reduction and if nullmove is succesful you only can check it with the verification search which can be extremely shortened.

Downside is that you start reducing tactical moves. Outside of ProbCut, this was never succesful. So I don't know. Maybe it helps if the reductions are very common, so you reduce in many places and can make up in doing more iterations. But then the Singular Extensions and the still existing normal search may make more iterations impossible. Anyway it's just a very short piece of code and nothing really new either.

What I never got working was something like Singular Extensions for the All nodes. Grandmasters just as well select only one or two moves in those 'nodes' in their thought process, so if we still want to mimic that, one day we will have to find a way. Of course modern programs like Stockfish do reduce an awful lot with Late Move Reductions, and LMP but that is only partially driven by eval much more by sorting the moves by type only.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Pos 11, 12, and 13.

Pos 11:
[d]8/5K2/3p3p/3p3P/pp1P4/rkb1R3/p1p3P1/n1B2B2 w - - bm Rd3; dm 16; id "je 11"; c0 "e3d3";
...
Pos 11 seems too hard but becomes easy if you give the first move Rd3. So that is probably only solvable without nullmove in the critical line.
Zappa made it here, I didn't even switch off nullmove, neither didn't I switch on the mate extensions: (with those on another trial took even some longer, so default seems to be best here, only tbs were switched off)

Sorry for german abbrevations, forgot to change that before starting once again, but at least I did restart the GUI

H4 was much faster, also default but without tbs, pity german abbrevations again.

From a general search point of view, I'm keeping fingers crossed for this patch from Jörg. It just might pass! But then it still would have to go to LTC.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Zappa was a very interesting program. A pity that Anthony buried the sources somewhere in the desert, in what was it, Arizona or New Mexico? :)
