These are not matches, but hard positions selected from various forums and ranked according to Shashin's theory.

Re: ShashChess
Right, chosen positions. But I am also referring to the 15 games mentioned above. Were they hand picked openings for the same purpose? I did not play thru them (yet).amchess wrote: ↑Fri Sep 17, 2021 12:40 amThese are not matches, but hard positions selected from various forums and ranked according to Shashin's theory.

Re: ShashChess
With only 20 games, these results are almost certainly going to be impossible to reproduce anyways. Meaningless

If indeed the idea of the games and test positions is to 'showcase' somehow the Shashin theory, then all you have to do is find another 20 openings leading to positions would allow the same.
There is nothing wrong with that of course. It simply is what it is.

Re: ShashChess
My point was that, were you to run this same match again, you could get drastically different results. You're looking at what amounts to a coin toss.Cornfed wrote: ↑Sat Sep 18, 2021 3:13 amI disagree.connor_mcmonigle wrote: ↑Fri Sep 17, 2021 11:58 pmWith only 20 games, these results are almost certainly going to be impossible to reproduce anyways.

Re: ShashChess
The same time control, exact same openings - leaving book at the position they did again and... instead of 4 wins, 1 loss and 15 draws...it could just as well end 1 win, 4 losses and 15 draws or some other 'drastically different' result? No, I don't think so. Some of the factors would need to change.connor_mcmonigle wrote: ↑Sat Sep 18, 2021 6:51 amMy point was that, were you to run this same match again, you could get drastically different results.

I believe they simply chose specific opening positions to play just as they say they did for the test positions...just to demonstrate Shashin theory at work in ShashChess.

Re: ShashChess
I put together HTC114 from Vincent Lejeune, ERET from Walter Eigenmann, Arasan- testsuite from Jon Dart, remove the doubles and add 77 more out of my personal collection of difficult positions to have 500 all in all.
With these I run A-B-engines with 30 threads of an 16x3,5GHz avx2- CPU (or GPU- based ones with an NVIDIA 3070ti) 10"/positions, 1G hash, default settings (ShashChess without experienc- file and all GM- options unchecked), Syzygy Probe Limit 5.
Here both had the latest green net from SF- dev- site:
Code: Select all
Program Elo +/- Matches Score Av.Op. S.Pos. MST1 MST2 RIndex
1 ShashChess18.2-nn13406b1dcbe0.nnue : 3513 9 405 53.6 % 3487 399/487 2.0s 3.4s 0.94
2 Stockfish170921 : 3487 9 405 46.4 % 3513 354/487 1.8s 4.0s 0.86
MST1 : Mean solution time (solved positions only)
MST2 : Mean solution time (solved and unsolved positions)
RIndex: Score according to solution time ranking for each position
Postions, that aren't solved by any opponent, aren't counted, so here 487 instead of the full 500 are rated.
You have to define a starting value, here I gave 3500 Elo as an estimation to start with regards
Peter.

Re: ShashChess
Modern chess engines behave like chaotic systems as slight perturbations to initial conditions can evolve into very different behavior. Many factors can lead to these perturbations: OS using time for some background process, thermals affecting clock speed and nps, etc.Cornfed wrote: ↑Sat Sep 18, 2021 7:32 amThe same time control, exact same openings - leaving book at the position they did again and... instead of 4 wins, 1 loss and 15 draws...it could just as well end 1 win, 4 losses and 15 draws or some other 'drastically different' result?
