Hi Walter!

They are of course not unsolvable, but I think the programs probably have different problems with these studies...
Thanks for the five very fine pieces, I didn't know any of them so far.

Hardest ones seem to be nr.2 and 3 (Hörning and Bondar), which really seem to demand something like the "MagicTacticSolver" in the SF- version Mobmat showed, if it goes for SF-

This code of MagicTacticSolver goes back to a user called Romeo in Outskirts, who came up with it for some CFish- compiles of his own, Marco Zerbinati had it in some of his SugaR- versions, the revival from February is here on github:

https://github.com/official-stockfish/S ... ccbc4bbb3f

Of course MTS checked isn't usable as for game- playing.

Yet both are solved quickly (at least as for the first move of each of both studies) by LC0 as you probably have seen on your own trials already.

Nr.3 Bondar:
2k5/p2p4/1P6/P3p3/1q2N3/2p5/K7/7Q w - - 0 1

BTW, thanks for bringing "MagicTacticSolver" back to mind.

What is this: 24 threads of 3x12GHz(!) CPU, 32G hash.
Maybe 24 threads of 12x3GHz CPU with HT.

In my case, the first of the five offers the most resistance.
(I rarely use the MV mode for puzzle tests to have a minimal comparison with the tournament practice)

I just bought a Komodo 14 and played around a bit :-)
(60sec - Ryzen7 - 16Threads - 2048MB Hash - 5-men-Syzygy)

But Komodo doesn't seem to like crackers :-(

Komodo 14
1. Weiss hält remis - Michal Formela, Studie 2019 > 60s.
2. Weiss setzt matt - Gerd Hoerning, Studie 2004 > 60s.
3. Weiss setzt matt - Ivan Bondar, Studie 2001 > 60s.
4. Weiss gewinnt - Gerhard Josten, Studie 2001 > 60s.
5. Weiss hält remis - Michal Formela, Studie 2020 > 60s.

A little better with Monte Carlo search:

Komodo 14 MCTS
1. Weiss hält remis - Michal Formela, Studie 2019 > 60s.
2. Weiss setzt matt - Gerd Hoerning, Studie 2004 > 60s.
3. Weiss setzt matt - Ivan Bondar, Studie 2001 > 60s.
4. Weiss gewinnt - Gerhard Josten, Studie 2001 Gelöst in 4.03s/13; Gelöst: 1
5. Weiss hält remis - Michal Formela, Studie 2020 Gelöst in 48.05s/20; Gelöst: 2

Then I tried SugaR:

SugaR-NN 260120
1. Weiss hält remis - Michal Formela, Studie 2019 Gelöst in 36.92s/35; Gelöst: 1
2. Weiss setzt matt - Gerd Hoerning, Studie 2004 > 60s.
3. Weiss setzt matt - Ivan Bondar, Studie 2001 > 60s.
4. Weiss gewinnt - Gerhard Josten, Studie 2001 > 60s.
5. Weiss hält remis - Michal Formela, Studie 2020 Gelöst in 2.47s/20; Gelöst: 2

With MCTS also 2 solutions, change 1-2 :-)

SugaR-NN 260120 MCTS
1. Weiss hält remis - Michal Formela, Studie 2019 > 60s.
2. Weiss setzt matt - Gerd Hoerning, Studie 2004 Gelöst in 43.84s/45; Gelöst: 1
3. Weiss setzt matt - Ivan Bondar, Studie 2001 > 60s.
4. Weiss gewinnt - Gerhard Josten, Studie 2001 > 60s.
5. Weiss hält remis - Michal Formela, Studie 2020 Gelöst in 5.56s/22; Gelöst: 2

Extremely impressive is LeelaZero!

Lc0 0.25.1 t60-304 ( RTX2080 / 1Thread )
1. Weiss hält remis - Michal Formela, Studie 2019 > 60s.
2. Weiss setzt matt - Gerd Hoerning, Studie 2004 Gelöst in 4.30s/14; Gelöst: 1
3. Weiss setzt matt - Ivan Bondar, Studie 2001 Gelöst in 3.59s/12; Gelöst: 2
4. Weiss gewinnt - Gerhard Josten, Studie 2001 Gelöst in 15.80s/18; Gelöst: 3
5. Weiss hält remis - Michal Formela, Studie 2020 Gelöst in 14.84s/22; Gelöst: 4

As for the to me second hardest one, Bondar's study, again CorChess, this time using 5 multi variant lines with same hardware as above:

They are of course not unsolvable, but I think the programs probably have different problems with these studies...
Thanks for the five very fine pieces, I didn't know any of them so far.

Hardest ones seem to be nr.2 and 3 (Hörning and Bondar), which really seem to demand something like the "MagicTacticSolver" in the SF- version Mobmat showed, if it goes for SF-

This code of MagicTacticSolver goes back to a user called Romeo in Outskirts, who came up with it for some CFish- compiles of his own, Marco Zerbinati had it in some of his SugaR- versions, the revival from February is here on github:

https://github.com/official-stockfish/S ... ccbc4bbb3f

Of course MTS checked isn't usable as for game- playing.
I'd like to thank Glarean for the problems too! :wink:

For the MagicTacticSolver, i first saw it appearing in Thothfish (http://talkchess.com/forum3/viewtopic.p ... =ThothFish ). As you mentionned, it does not play good chess, but will solve some problems that many engine won't ever be able to. For example this study of Smyslov, currently problem #41 in arasan20.epd: 2b1rk2/5p2/p1P5/2p2P2/2p5/7B/P7/2KR4 w - - bm f6 is very hard to solve for game playing engines.
