the 1st one makes more sense

I meant the first one. Thanks for pointing that out.

Scratch Chess Engine Ranking (on Scratch 3 Runtime)

17	Mystery		1230	268	386	3	0%	45	0%

Data is still limited, too few games played. Bottom ELO numbers should be even lower, some rankings certainly wrong - Archimedes, The Turk too high, White Dove too low (currently facing some Scratch 3 issues). Midecah is the engine which has never drawn let alone won a game and should be last.

BTW, Midecah was very close to a repetition draw against Scurious right now. I started even crossing fingers for Midecah, like a once in a lifetime chance, but no - instead of making the next identical check-evasion, it chose not to.

Thundershark is not in the list, because it was designed for TurboWarp only. U0 has been taken offline it seems.

You can find the engines in this studio: https://scratch.mit.edu/studios/15896412/

I must say this is currently rather Innacurate as Scurious can easily beat Chip, Archimides and Turk, also Frenchgamerlol is way stronger and Midecah chess definately isnt 1200. White Dove also is definately in the top 4.

New GoK Development Version

The previous way how GoK evaluated castling and resulting positions (esp. king protection) was the result of tweaking bits and pieces over several years, including a dynamic component favoring early castling. Yesterday I threw away all the code and re-implemented all of that. Only one game so far against the previous version, which it won. I would appreciate further tests, as it is quite a change. My test automation project is still not done yet. GoK Dev can be found at https://scratch.mit.edu/projects/828094886/

I also reverted LMR to the January implementation. It is less spectacular, but is also on the safer side. It is more important to see something that becomes visible at ply 8, than get to ply 12 and only see it here, esp. as competition won't reach that depth.

Is it just me, or did you also lose that lichess.org analysis board feature that would show you the next best move via a blue arrow once you activate local evaluation? I now have to hover over a variation in the PGN moves panel, and that only appears during live analytics (https://lichess.org/analysis/), not on a stored game.

Thanks, good to see GoK castled at the right time. GoK Medium also played a good game against WD already: https://lichess.org/geJ2aqvs#129

Game #2 against WD was similar, and as before, the one blunder does not happen on Difficult, search-depth related: https://lichess.org/rGFuqJL6#143

I left the aggressive LMR activated for Scratch 3, it has some advantages there, think time among them.

You can see the changeset here: https://github.com/ArnoHue/scratch/commit/b799c201c91b76ca907286de9562c8e3862fb8bc

Yes, as stated before, some calibration games missing, but the trajectory is correct. I did some of those yesterday, and it improved things immediately already. Three times I had White Dove playing, each time it messed up the board on P=2, so there was nothing I could do. I will try again today, as S_P_A_R_T has fixed that now.

And as said, those are not FIDE numbers. Also, for Midecah to fall to 1000 or similar, it must play more games.

WD's bug has still not been fixed sadly. I've been quite busy with my YT Channel (again). I've just been spending 100% of my time on that for the past 2 weeks to get it to 1000 subs (only 3 away right now!). But today, I'll hopefully start debugging the issue.

(The bug is also really weird in the way that you'd expect the bug to happen in TW, as it's just faster S3. But no… It just doesn't occur on TW. And I've even tested S3 without the q-search limiter and it still bugs out.)
