CCCC continues and Leela, along with Stockfish, Houdini, Komodo and Fire, already has secured a place in the 2nd stage.
Ethereal after a strong finish, mainly winning in the last games, has almost secured the promotion. Booot has also many chances.
While Shredder and Andscacs are the ones that are competing for the final 8th place right now with Shredder to be ahead, but having difficult opponents to face in the next 4 rounds.

ROUND 38
 Fire in a sharp Sicilian Najdorf line, managed to win after a blunder of Leela. If Leela would have found the correct move she would have drawn the game. This CCCC net that is playing, i.e 11089, has tough time to find the correct move and it sticks to the blunder after even more nodes examined than it did in the game. But thankfully most newest nets of Leela find the correct move instantly and stick with it. Out of 20 nets of test10 that have been tried only 3 play the losing move and the other 17 play the correct move easily as also the correct continuation. So it was just a bit of bad luck for Leela. She is not perfect anyway. :)
 And of course this "she" is a bit ambiguous since there are so many nets of Leela and most are untested, so no one really knows which is the strongest. For sure though, the 11089 that is participating in CCCC, is not the strongest as the nets after 11150 are surely stronger.

Ethereal had its 2nd win on the row and now things do seem better for his chances to promote. While Shredder had a shock loss from Xiphos and now struggles with the promotion! Andscacs lost from Houdini and also is on a bad situation about promotion.

ROUND 40
Leela with black won against Arasan in a beautiful game and Ethereal had its 4 win in the last 4 games and now it's the favorite to promote.
Boot drew with Laser and so Andscacs too and both took advantage of Shredder's loss to Stockfish.
 In that game Shredder showed how not to play French with white! And it was against Stockfish that of course grabbed the chance and did not forgive anything! No favors to Shredder from the leader. Shredder did have a really bad game and completely lost track of the position and Stockfish won rather easily.

ROUND 41
Leela won another nice game against Wasp this time, again showing some signs of not being able to provide the crushing move, the move that will win easily, but still managed to get a comfortable win in a game of zugzwangs. A really beautiful game played by Leela that won because it made her opponent to be in a zugzwang a-la Nimzowitsch style!

While Ethereal is on a roll since it made its 5th win in the lats 5 games and now it's seems improbable that will not promote. Boot won against Ivanhoe also almost securing its place in the 2nd stage. Andscacs drew against Fizbo and lost a big chance to take a valuable full point since Shredder won against Senpai easily.

ROUND 42
Stockfish continues its rampage winning the last 8 games.
Leela also won a very nice game with black outplaying positionaly Texel with some very nice moves.
Shredder won against Nirvana and Andscacs lost to Fire and now it's the outsider for promotion even though Shredder has to play difficult opponents in next 4 rounds.
Booot and Ethereal got 2 draws but probably this would not cost them as they will promote.


493 Fire vs Andscacs 1-0
494 Fizbo vs Ethereal 1/2-1/2
495 Crafty vs Fritz 0-1
496 Gull vs Booot 1/2-1/2

  1. Congrats to the whole Leela team and community! Yay! 😊

    In stage 2 of CCCC, pondering will be off. This may dramatically improve Leela's time management performance! (Out of principle, I'm against this change; they could always just fix things and try again next competition; in the mean time, Lc0 might have time to patch up the time management to work more optimally with pondering; but, I understand their decision anyway.) Thus, her chances of getting into the top 2 have (in my eyes) gone up significantly! Wow. 😲

    Unfortunately, they've also announced that stage 3 will have pondering back on again (if they can fix the underlying issues with it). That means if Leela performs great in stage 2 and makes it to stage 3, without any update, she may end up with a rather dull performance in the finals. 😭 Ugh.

    Well, we'll see. Maybe they'll allow a small patch to handle time management between stages 2 and 3 (assuming she makes top 2 in stage 2). 🤔

    (And, unfortunately, all this changing the settings back and forth will lead to all sorts of needless controversy (even more than what was needlessly started in the first place), so no matter the results, I think many people will consider them ambiguous at best, and suspect or bogus at worst. Ah, well. 🤷‍♂️)
