Pesky FEN of the Day

Post by MOBMAT » Wed Aug 05, 2020 11:03 pm

I found this M20 position in my "never tried these before" list and found it particularly difficult for just about every engine.
Granted I only have 6 threads and 16GB of hash available, but still, it is only a mate in 20.


Houdini 6 (with Nalimov) was the only engine to actually solve it, but it took it overnight to do so. Sorry, I cleared the analysis and don't have it.
CorChess 6.0 and BrainFish 200724 found M21, and Crystal 080420 found M22, so they would probably find the M20 overnight as well. Other engines, well, try your luck with more threads and RAM.

The only reference I could find to the position was that it was in the WCSAC list of 1001 positions. It is #161.

Dann, have you tested the WCSAC list of positions? I might run through them to see if they seem to be easy or difficult.

I have tested every position from every test set I know of, but some of the older ones were not tested on the latest and greatest hardware, so I will look up that one and see what I have for it
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 did not even have it resolved to mate:
8/3n2kp/p3p1p1/4P1P1/4Nr2/PK6/2B5/8 b - - acd 34; bm Rxe4; c0 "level: easy-1"; c3 "Rxe4"; c4 "Reinfeld.161.1001"; cce -0; ce 9086; pm Rxe4; pv Rxe4 Kc3 Nc5 Bd1 Rxe5 Kb4 Rxg5 a4 h5 Kc4 h4 Bf3 h3 a5 h2 Kb4 Nd7 Bh1 Rg4+ Kc3 Rg1 Ba8 Nc5 Kd4 Nb3+ Ke5 h1Q Bxh1 Rxh1;

I will take a closer look now.

I am testing right now with SF NNUE, but on a wimpy machine. My strongest machine is tied up now, and some of the others are shut down for the peak of the summer. But after 5 minutes the score is +38 pawns so I guess it will resolve to mate pretty soon

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.

Crystal was clearly stuck on a fail low, so it may have been ready for a breakthrough.
But SF-nnue is really starting to catch my eye.
