Thanks for watching. Chess is the best!!
Top Chess Engine Championship, formerly known as Thoresen Chess Engines Competition (TCEC or nTCEC), is a computer chess tournament that has been run since 2010. It was organized, directed, and hosted by Martin Thoresen until the end of Season 6; from Season 7 onward it has been organized by Chessdom. It is often regarded as the Unofficial World Computer Chess Championship because of its strong participant line-up and long time-control matches on high-end hardware, giving rise to very high-class chess.
The TCEC competition is divided into seasons, where each season happens over a course of a few months, with matches played round-the-clock and broadcast live over the internet. Each season is divided into several qualifying stages and one "superfinal", where the top two chess engines play 100 games to win the title of "TCEC Grand Champion". In the superfinal, each engine plays 50 openings, once as each side. Beginning in Season 11 in 2018, a division system was introduced; the top 2 engines in each division are promoted, and the bottom 2 are relegated. Currently, there are 5 divisions (a Premier division, and divisions 1-4); newcomers generally start in division 4.

Jacket again looks great though.

See, and ask if your wife, will put the link in description, to, the jacket, where to buy it. 😂, incase anyone wanna check it out.

[@Jozarovschesschannel]

Actually this is a hoodie that has a long story. It is a hoodie with a Lichess logo and my brother in law Agadmator bought it for himself. Then my sister washed it at high temperatures and it shrank. Because Agad is much taller it's pefect for me and he gave it away and now I have it

[@letsmakeit110]

re: letting the engines choose their own openings; i'm also curious if stockfish could beat a tier 3 engine like nirvana from the starting position.

[@pukulu]

The addition of the little neural net has made a big difference. Stockfish went on to win this match by 9 points. I'm currently following another season 19 TCEC 100 game bonus match at 30 5 time control between stockfish (classical) and stockfish (nnue). It's a slaughter. The neural net really makes the thing stronger, especially positionally. In difficult positions, stockfish (classical) is losing.

[@MordimersChessChannel]

I have exactly the same thoughts about dubious lines. While checking some sidelines where one side defends with some potential counterplay is cool and definitely needed for the unbalance purposes, the basic opening mistakes which are easily refuted aren't enjoyable to watch. And I also would love to see the pure engine games from move 1, maybe with some a bit more aggressive setup but still, it could confirm the best choices by the engines.

[@hassanhubbi8289]

Oh my God what a tactic! This A5 move is stunning

[@Jozarovschesschannel]

A5 was awesome, it was a very important moment of the game. With a potential b5 pawnbreakthrough motif black could have good chances in the game

[@shotx333]

1:36 I fully agree.

[@ayonmaity6150]

Jozarov Sir please cover Stockfish's win vs Lc0 in the Alekhine defence in round 60.Stockfish played like AlphaZero in that game. Looking forward to your analysis of the game ❤️💓

[@Jozarovschesschannel]

I will

[@ayonmaity6150]

@@Jozarovschesschannel Thank you Sir ❤️💓

[@letsmakeit110]

the engine is called neural network stockfish, but it could just as easily be called matrix search leela, no? basically a combination of the two top engines.

[@anweshmajumder6605]

The problem with playing from opening position is that it would almost certainly be a draw. Like humans, engines like to play solid lines. Engines have little to no chance of going wrong in solid/classical lines

[@thewarlordscalling6537]

it wouldn't hurt any1 for us 2 c a few of those draws

[@Jozarovschesschannel]

Yeah, the result wouldnt be so important. Just the opening line. And on the other hand Many great games have been also played in this so called “drawish openings” with immortal attacks

[@thewarlordscalling6537]

tcec org,please put 6 games without pre-arranged moves next tourney.

[@Jozarovschesschannel]

At least one time

[@jasonz9902]

I'd like to see them play without opening moves provided. I'd like to see what they'd play.

[@Jozarovschesschannel]

Me too

[@Stockfish1511]

We know what they prefer. They usually play e4 and play openings like french, queens gambit declined, sicilian, ruy lopez, giocco piano. If they play without book at this time control of 120 mins and 10 sec increment will be 96-97 percent draws although im confident sf will still win. It no longer has bookless weakness after nnue. At lower time control stockfish will win by bigger marigin. Its way to strong as of now.

[@jasonz9902]

@@Stockfish1511 interesting I guess it will never happen is what you are saying.

[@Jozarovschesschannel]

In faster time format Stockfish is a monster. I agree with your choice of openings. Even if Many draws would happen we could see the last and deepest lines of that openings

[@Stockfish1511]

@@jasonz9902 The problem is not playing without the book. Problem is that if they play without book, the games will very repetetive and similar to each other which will make the tournments very boring. Viewers want to see blood tbh lol. But they do play bookless sometimes. But if you want to what they prefer. Well both prefer e4 as white. But sf likes to get into french, giocco piano in bookless, while leela prefers french, ruy lopez. Although they both do tend to switch etc. Also stockfish sometimes prefers c4 isntead of e4

So the most advanced versión of Stockfish AB engine couldn't defeat Lc0.

[@emacsultron6212]

Are there any games where black actually wins?

[@GenesisOfPorcupines]

No such games in the Superfinal but there were few in Division P (won by SF and Leela vs other engines with black).

[@Jozarovschesschannel]

There are a couple

[@nbrain1595]

there have been multipl test runs between seasons without prearranged openings. not only are they all drawn, they also allways play the same openings. they where all super boring...

[@mikekenworthy]

My interest in this game declined dramatically after QF6. As you said (In different wording) A daft idea.

I just dont like stockfish winning
