stockfish could find without multi-pv f4 in the second problem and changed its mind at depth 93.
Maybe at depth 94 it is going to change its mind again to Bd1

I forgot to stop the analysis and found that stockfish can change its mind even at higher depths

Re: Why is Stockfish with NNUE so blind sometimes

Post by Eelco de Groot »

It seems a nice problem for beginning programmers to try maybe, because have feeling it may not be so difficult to get a better performance at least with these two positions, but just a feeling. No working compiler yet so I leave it for the moment. Jörg says, position two is probably search related. Position one could also be search related because the NNUE evaluation (+ PV search), if you make the first move 1...Rf6, seems far superior. So, with NNUE, PV search is clearly better, but the nullwindow search with NNUE is inferior. Of course this is only one position, and I did not try the second at all.
Is not totally clear though what the influence of eval is here because with search depths below 30, the evaluation with NNUE is zero, and without NNUE it is negative. But from depth 30 begin Fail Lows.


Tried Black Marlin 14.7 from dorsz from Open Chess:

Without Multi PV the best move is not found at least not in reasonable time. With Multi PV = 3 and after a search with Multi PV 1 and with 2 so a lot of nullwindow searches in transposition table:

For some reason these position will not copy and paste into HCE pro? No idea why

You're right, didn't notice till now neither, that HCE Pro needs move count- info to paste.
Like this it does work:
2k2Br1/p6b/Pq1r4/1p2p1b1/1Ppp2p1/Q1P3N1/5RPP/R3N1K1 b - - 0 31
(or with 0 1, in original game it's move nr.31...)
BTW with old HCE 1.10.1 it does work without move count too.
Peter.

Hi Eelco!
Eelco de Groot wrote: ↑Tue Jan 11, 2022 11:39 am It seems a nice problem for beginning programmers to try maybe, because have feeling it may not be so difficult to get a better performance at least with these two positions, but just a feeling. No working compiler yet so I leave it for the moment. Jörg says, position two is probably search related. Position one could also be search related because the NNUE evaluation (+ PV search), if you make the first move 1...Rf6, seems far superior. So, with NNUE, PV search is clearly better, but the nullwindow search with NNUE is inferior. Of course this is only one position, and I did not try the second at all.
Is not totally clear though what the influence of eval is here because with search depths below 30, the evaluation with NNUE is zero, and without NNUE it is negative. But from depth 30 begin Fail Lows.
As for the first one position (Sirobaba F.-Chaika I. ICCF 2011), here's Dragon 2.6 with Selectivity 10 (min.) and Reductions -200 (def. -20, min. -500), everything else default (except no Syzygys used, Table Memory 512), 30 threads of 16x3.5GHz Ryzen, 32G hash:

So default even a bit better.
Problem of course, as said from others already here, with this position is also, that Black wins with 31...Be3 and with 31...Rd7 too, even if not as qickly and as beautifully as with best move 31...Rf6.

As for the Salai- study after 5 minutes with default params no winning solution, will give it another one try with setting of before, if it helps, I'll come back with it.

Seclectivity and Reductions only didn't help.
Best setting so far is this one: Aggressive Personality (which switches off NNUE- usage, as far as I know), Selective 10 (min.) Reductions -500 (max.), Nullmove unchecked, 6men Syzygys.
Same hardware as before, again 32G hash:

In two further trials one was <2 minutes time to solution too, worst one was 3' 25".
As presumed still no real competition against Sting, SugaR AI ICCF (which currently again isn't developed anymore) sometimes gets it rather quickly, but then takes more than 5 minutes once in a while again too, Crystal 4.0 not any better at a single try, ShashChess 20.1 with MCTS single and option Tal took 7 minutes at a single try.
All of those with and without parameter- settings profit from MultiPV of course too, as well as SF dev. does as shown by Uri already. As for the Chaika- game- position MultiPV=3 is enough normally to have ...Rf6 over ...Be3 and ...Rd7 rather soon.

Seclectivity and Reductions only didn't help.
Best setting so far is this one: Aggressive Personality (which switches off NNUE- usage, as far as I know), Selective 10 (min.) Reductions -500 (max.), Nullmove unchecked, 6men Syzygys.
Same hardware as before, again 32G hash:

In two further trials one was <2 minutes time to solution too, worst one was 3' 25".
As presumed still no real competition against Sting, SugaR AI ICCF (which currently again isn't developed anymore) sometimes gets it rather quickly, but then takes more than 5 minutes once in a while again too, Crystal 4.0 not any better at a single try, ShashChess 20.1 with MCTS single and option Tal took 7 minutes at a single try.
All of those with and without parameter- settings profit from MultiPV of course too, as well as SF dev. does as shown by Uri already. As for the Chaika- game- position MultiPV=3 is enough normally to have ...Rf6 over ...Be3 and ...Rd7 rather soon.
Hello Peter,

Houdidit (Houdini 6) seems to solve the f4! position rather quickly with default settings:
