TCEC Cup started! CCCC variants tournament continues....




The TCEC Cup has started and 2 match pairs will be played every day.
We remind that 32 engines will compete in a Knockout elimination tournament, and in each pair match, the best out of 8 games will promote to next round.
That means if an engine completes first, in the 8 games, 4.5 points will promote. As per their decision if an engine completes first 4.5 or 5 points, the match is stopped and the engine promotes to next round. So not all 8 games will be played if not necessary.
Also the tournament would not necessarily be continuous like normal TCEC, since only 2 pairs will be played every day even if there is time for more. The games will begin 12:30 UTC every day.

Till now Stockfish crushed Ivanhoe with a 5-0 score and promoted and Gull won 4.5-2.5 against Texel and will play Stockfish in next round.

According to the above, today there will be the Fizbo- Hannibal and Chiron-Nemorino matches, on Sunday Fire-Senpai and Vajolet-Booot and Leela will play on Monday against Laser as also Ethereal against Rodent.

The TCEC Cup format:



Meanwhile in Chess.com the variants games are being played right now.

In the f2-Pawn missing Chess variant Leela did fine and actually got first, because of having higher SB tiebreaker score, since she won Stockfish with black and with white. Interestingly out of the 30 games that have been played in this Pawn odds Chess, there was only 1 win with white pieces, the Leela-Stockfish one, 15 with black pieces and 14 draws.

In the 3 Queens variant as it was expected, Leela did terribly, since not having seen before this position in her training and having seen probably very few positions with 3 Queens each side in her training, Leela could not play this variant at all.
Houdini also did terribly here, since it was crashing in every game since it doesn't support obvious illegal Chess positions because of material(since generally Houdini supports not valid Chess positions like this FEN 1r5b/3nk1pp/1p6/8/2P5/3B1P2/P4KP1/2R3R1 w - - 0 1  but does not support Chess positions with not valid material since in this variant each side has 3 Queens and 8 Pawns so the Queens couldn't come from promoted Pawns so this is an illegal Chess position and Houdini must have a counter to count such things, like this one).

In the Knightmare Leela did also terribly since again she hasn't seen this position in her training and she couldn't have seen this as like the 3 Queens variant, Knightmare's starting position also is not a valid Chess position so you can't expect Leela to play it. Houdini also crashed again in every game as it doesn't support such obviously not valid Chess positions.

In the One row up Chess variant, that is almost complete Leela had 8 draws and one loss so far.


Here are the standings in each variant:

    1. You can force the engine whatever opening you like (use opening book) or use temperature.Without those, all her choice depends on the statistics of win/loss in her training. ( e.g If the network you use has 51% win rate in d4, and 50.5% win rate in e4, she will never play e4)

  4. I think that Leela does best in closed openings, because the lines are longer so that AB engines don't see everything in their horizons. Problem is with 1.e4 there are so many ways to simplify quickly

  5. This program will give a very hard time to stockfish. (i am not sure it will lose, you may see a big surprise)
    I am a correspondence chess GM.I have been trying it for a week now (2xe5 2699 ve 36 cores at 3.3Ghz with RTX 2080) i am very impressed:
    I think that actually it is already better than stockfish in opening and middle game.
    Once the endgame evaluations are better, I dont think stockfish would be able to hold. (for some reason, it is not able to use syzygy very effectively)
    Best would be a program combining two NN+AB (like stockfish and lc0 analyzing together, getting feedback and chosing the move together)
    I will not be surprised id this program beats stockfish in this tournament. everything depends on the ending. It will get equal or winning positions until the ending against stockfish.
