Does not work in UCI mode - this is a known issue.
In which mode does it and where are the learning- entries stored? In book.bin? Is it about book- learning only or is it a feature for all played or analysed moves?

Latest version here: https://arasanchess.org/arasan2023.epd.
Can you explain the solution of these test positions?

Code: Select all

8/7p/5kp1/4p3/p3rPRP/3K2P1/8/8 b - - bm Kg7; id "Arasan2023.17"; c0 "Flohr-Geller, URS-ch Final Moscow 1949";

First one isn't a game changer, and if e.g. next best 1...Rd4+ is much weaker, won't be easy to prove. Crystal after some Forward- Backward and 1...Kg7:
[d]8/6kp/6p1/4p3/p3rPRP/3K2P1/8/8 w - - 0 1 Analysis by Crystal 6 PMT:

2.h5 a3 3.Kxe4 a2 4.hxg6 a1Q 5.gxh7+ Kxh7 6.fxe5
Black is clearly winning: -+ (-96.91) Depth: 22/55 00:00:03 148MN, tb=1233673

and after 1...Rd4+:
[d]8/7p/5kp1/4p3/p2r1PRP/3K2P1/8/8 w - - 0 1 Analysis by Crystal 6 PMT:

2.Kc3 Kg7 3.Rg5 Re4 4.Kd3 Re1 5.Kd2 h6 6.Rg4 a3 7.f5 a2 8.Rxg6+ Kf7 9.Kxe1 a1Q+ 10.Kd2 Qb2+ 11.Kd3 Qd4+ 12.Kc2 e4 13.Kb3 e3 14.Rxh6 Qd3+ 15.Kb4 Qxf5 16.Ra6 Qd7 17.Ka5 e2 18.Kb6 Qb5+ 19.Kxb5
Black is clearly winning: -+ (-96.65) Depth: 28/55 00:02:52 7918MN, tb=77384156

Time to best eval for second one is a little higher maybe but you're right, not enough discrimination for a single best move position.

Second one in MultiPV=3 again after some Forward- Backward in depth 50:
[d]1r2r1k1/2R2p2/1N1Rp2p/p2b3P/4pPP1/8/P4K2/8 w - - 0 1 Analysis by Crystal 6 PMT:

1. = (0.00): 1.a4 Red8 2.Rxd8+ Rxd8 3.Nxd5 exd5 4.Ke3 Rb8 5.Rd7 Rb3+ 6.Ke2 Rd3 7.g5 hxg5 8.fxg5 d4 9.g6 Re3+ 10.Kd2 Rd3+
2. = (0.00): 1.g5 Red8 2.Rxd8+ Rxd8 3.Nd7 e5 4.Nxe5 Bxa2 5.Ke3 Rb8 6.Nd7 Rb3+ 7.Kxe4 Bb1+ 8.Kd5 hxg5 9.fxg5 Rb5+ 10.Nc5 Rb4 11.g6 fxg6 12.hxg6 Bxg6 13.Ke5 a4 14.Ra7 Rg4 15.Rxa4
3. = (0.00): 1.Ra7 Bxa2 2.Nd7 Rb2+ 3.Kg3 Rc8 4.Nf6+ Kg7 5.g5 Rc3+ 6.Kg4 Rg2+ 7.Kh4 hxg5+ 8.fxg5 Rh2+ 9.Kg4 Rg2+

So not a good single best move test position neither, regards
Peter.

Stockfish doesn't show a clear advantage for the 2nd position, but it does select g5.

Took out these two and nr.189, [d]4K1k1/8/1p5p/1Pp3b1/8/1P3P2/P1B2P2/8 w - - 0 1 because this one Salai- study is too difficult for STC and has a dual with 1.f4 and 1.Bd1.
I then added Eret (Eigenmann Rapid Engine Test) minus 8 of it, 594 single best move positions from STS (Strategic Test Suite from Swaminathan and Corbit revised by Schröder and Mosca), 60 UHO- positions from Stefan Pohl's sets and 157 easy endgame studies out of HHdbVI (Harold van der Heijden database).
So I have 1111 positions of a rather homogenous level of difficulty for modern engines on modern hardware at 1"/position or less, preferably single thread for an even wider spreading of results.

A lot of the positions in that epd have the wrong best move. A simple google search gives different results.

These are just some of them. I don't know if you are manually changing the best move or if they are unintentional mistakes.

The first of your two choices is true (I intentionally changed bm from sources, especially from old STS, sometimes even from Ed's revised version of it):

As for the third one, you're right, mixed up there two of my many versions of STS with and without MEA- syntax. Won't have extra upload of the corrected suite, thanks for pointing out, just change that manually in your own one, and if you find further wrong ones, just show them too, please, so I don't have to check all of the positions on my own alone again, regards
Peter.

It should be avoid move, not best move.
