I was not able to replicate a5 (Nd4) on Stable or Dev versions of Element. I should add the #OfMoves into the FEN, but the move is the same after manually changing it. This could be due to some sort of FEN inconsistency (they are common in Element).

True, when I try to re-import it also plays Nd4. Also, it was very fast, compared to the general think time during the game.

GoK (10sec) vs. WD (P2) on Scratch 3 for a change, WD blunders twice and GoK wins surprisingly fast in 14 moves: https://lichess.org/QIncXlVP#27

Rematch, GoK (black) in control, and its two blunders won't happen on Medium (15s), as solutions are found at 12s each: https://lichess.org/RCaVIKph#136

GoK seems to have regained the edge on Scratch 3.

@HasiLover @ScratchChessChampion how did you conduct lichess.org broadcasts on live games played by Scratch chess engine?

I tried today, and failed, at least by using lichess-only means. I could get lichess games tamong two lichess.org users o show up in the broadcast (using game IDs), but noting else. For games between engines, I thought I could provide a study pgn URL, but it was not accepted in the broadcast settings. And an anonymous casual game will have two “Anonymous” players.

The documented alternative is to host the pgn file somewhere else (but how to update it constantly if it comes from a Scratch chess game?). I mean I could script all of that, but there must be an easier way?

Ah, I’ve encountered this challenge before as well. It’s quite straightforward: scroll down to the bottom left corner of the page to create a chapter, similar to how you would create a study on Lichess. You can edit the name, rating, and other details as needed. To broadcast the moves, simply make the moves, and they will update automatically. You can use another device to test and verify everything.

Oh I see, so you left the games URL empty, and did not use the broadcast manager at all? Great, I will try. Did not see that at all in the instructions, unless I missed it…

OK, I played the first game, again a hiccup as it did not detect the end of the game resp. its result, and I had to recreate the chapter via import. Maybe because I had started analysis once while the game was still running? OK, I have to add the result tag manually.

And the leaderboard is not being updated?! Minutes later after several refreshes it was.

Semifinal #1 again with high accuracy (GoK 98%, Shallow Blue 90%). I liked GoK's attitude on SB's 6. Qg4 attack, like “I don't care, I am doing my own thing”:

Make sure to rename or just delete the default “Chapter 1”

Semifinal #2, White Dove was up during midgame, after that it looked like a draw for a while, until White Dove blundered and Element skillfully maneuvered to secure its win at 93% accuracy:

The final thus is GoK against Element!

The final turned out to be a good game without blunders, GoK steadily increasing its lead, winning against Element in 33 moves, 97% vs. 89% accuracy:

Congrats also to Element, it played a great tournament!

Check out this endgame position between Shallow Blue 4+4 and Element 4+8! SB was black

r6r/pR3kpp/5p2/2p5/8/2bN4/P4PPP/4R1K1 b - - 0 22

GoK managed to find the correct solution (the move Kg6) at depth 10. It was initially found at depth 1 but then skipped. White dove (as far as I know) reached a depth of 9.

Good news, the ‘dev’ version of Destructor (not shared) is moving fast! Some notable improvements have been made.

@ArnoHu thanks for inviting !
Sadly, I don't have a lot of time to spent on chess except from my ahhh laggy python program ( who is definitively slower than scratch engines in average, I tested it out ), so I couldn't join. But the games were good !

-089-

aaaand here I go again, missing out on all the fun… I got an uncanny ability to miss big events, especially if they're something I'm interested in

I see you did actually add me.
but just for future reference; my lichess username is cs6667.

OK thanks, well, it is always important to not only verify the best move, but also the evaluation that led to it being considered best move. Only when its final effect is represented by evaluation, an engine has “truly” found it.

Great, will check it out soon again.

Yes, I remember from static code review there should be some tuning potential. And I strongly recommend a Python profiler like cProfile: https://docs.python.org/3/library/profile.html
