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.

Wow. Why isnt people watching more computer chess?! Its like watching two immortal people having thousands of years of knowledge and the intellectual capability that makes einstein look like average intelligence. Future is shining bright for AI and chess. Thanks for being one of the few unique channels that actually covers AI chess extensively, i really enjoyed this game! Though Watching this i had a eerie moment of clarity and foresight of the future.. realising AI will truly dominate our daily lives even more, their so powerful and capable of things we never dreamed off, i love it, Until they take our jobs :)

[@GoodKnightChess]

That evaluation bar is the most confused thing I've seen😹

[@Jozarovschesschannel]

Yeah it is, really hard to analyze

[@joshmorganelli6327]

For real. I was thinking the same

[@pukulu]

One of the biggest changes in Lc0 has been in its evaluations, which now are conservative and at one time were fluctuating wildly if you go back 3 or 4 seasons. Both engines are high class. There are differences but their similarities outweigh their differences, which is quite remarkable, since their programming is so different.

[@digitalartsdigitalcurse4512]

Loved this!!! Chess is teaching us even the most intelligent will lose when situation is against you.

Love that!

Fish NNUE is a beast. Title could be: The art of attack. Thank you Jozarov, I have to re-analyze this violent fight.

[@Jozarovschesschannel]

Sick stuff for sure

[@kohlerm113]

The beast lost the reverse ...

[@funandgames2339]

I 'm at 4:22 right now where black just played Bb7...Now I think I remember looking at some of the theory behind this a long time ago. It's so complicated that I've forgotten...but I'm pretty sure white goes e5 here and allows Bxg2. I hope I'm right. Would be cool to see how back logged my chess data base is in my head lol!

[@jahongirkodirov4471]

I learn a lot from ur videos, so informative, and thank you so much.

[@Jozarovschesschannel]

I'm so glad!

[@Corteum]

Wow, what a crazy intense game! If only I had some NZT-48, I might be able to find some of those lines. lol. Great analysis btw. Keep it up. 👍❤️

Finally..the great battle

[@vladavasiljev]

Really beyond human level...just scary a bit...

[@Jozarovschesschannel]

Scary chess, for sure

[@crackhex2649]

This just happens to be the ONLY game stockfish has won during this tournament, and leela has won one against sf

[@Jozarovschesschannel]

Yeah so far the result is equal

[@cheburashkacheburashka4257]

This is good - means both have room fot improvement

[@7777_Leo]

Stockfish = Chess monster Catfish = River monster

[@Jozarovschesschannel]

GOOD ONE

[@ChessSocialism]

I had this exact position at 5:05 as white not long ago and I was so scared for my rook in the corner, very weird to think I can just hold off for so long lol

[@Jozarovschesschannel]

It is possible to sac the rook in such lines

[@olivieraton9591]

It’s really really wild !!!

[@saarike]

This was so complex... huh! Thanks a lot for really interesting game.

[@Jozarovschesschannel]

Hard to analyze

@@Jozarovschesschannel I can imagine. 👍

[@MacDaniboi]

Why play a human opening?

[@danielgautreau161]

Engine endgames are often baffling. At 16:44 why does Black not play Nd3+ and Nxf2?

[@danielgautreau161]

After looking at it again, at 16:03 instead of White's Qxf3, the move e6 seems to produce an " anything wins" kind of position for White.

[@abgacg22]

@@danielgautreau161 why e6? fxe6 and...?

[@danielgautreau161]

@@abgacg22 I think I was mistaken

[@2phil4u]

I don't get it. My engine shows 11.Qh4 as a much better move with no more advantage for black. Did miss something or is this move very deep.

[@sebastianjercan]

It is very hard to follow you. In the middle of the video I do not know anymore which is the actual position...

[@Jozarovschesschannel]

Sorry about that. I’ll try to improve that

[@kingkura]

Agreed the stockfish win was more interesting.
