Leela doesn't use NNUE, used only by the classical engines, which use alpha-beta pruning, to advance their evaluation function using efficiently computed on CPU neural networks. Leela uses Monte-Carlo Tree Search with the deep neural network, which uses a GPU to perform an inference

What's your opinion of Armageddon w/ auction, even in classical and especially in 9LX? --- Part0of3 - Intro in CSQPod: A - 2:22 in B2Gi-6EgcfY ( clip for csqpod & MVL ) and B - rc-GquDy3PU ( CSQPod & hikaru ) To break up ties in classical 1v1 matches or knockouts ( as opposed to breaking up ties in round robins or swiss ) - MVL & Fabi don't want super long armageddon's to break up ties - Yet Hikaru & Fabi don't want rapid/blitz to break ties. Compromise: If you're going to do 25+10i rapid tiebreaks, then why not 25+35i classical armageddon tiebreaks? --- Part1of3 - If the point of classical 9LX is that, as said by the top player in - classical-time classical-variant chess Magnus, Carlsen, 9LX isn't suited to rapid/blitz - classical 9LX Wesley So, players don't play so consistently in rapid/blitz 9LX Then classical 9LX should have classical tiebreaks. Generally I'm known to have a huge bias against Magnus Carlsen the chess player (for being a hypocritical cheater), but Magnus Carlsen the 9LX player isn't so evil: Magnus is setting up classical as in 120min+ WITHOUT consecutively repeating starting positions (as FIDE had hypocritically insisted on doing in 2019 & 2022 WFRCC). --- Part2of3 - An armageddon with 120min+ for white might be too long, but there IS precedence of a 60min+ armageddon won by Gata Kamsky in an old USCC in 2010 and even sorta in 2013, I think. You can also do like 25+35i or even 10+50i instead of 50+10i or 60+0i, all of w/c all equivalent under FIDE's conversion. Rapid games are sometimes 25+10i, so just increase the increment by 25 seconds. --- Part3of3 - And I believe Bobby Fischer would like armageddon too (at least in 9LX if not chess). Bobby was preaching about pre-arrangement, but I don't think increments & 9LX are enough to solve this. In xiangqi, their armageddon has auctions and was invented by a Ronghua Hu known as - surprise surprise - the Bobby Fischer of Chinese chess! - pKdQYb Armageddon w/ auction makes every game fair & decisive. I believe this'd mean - A - no more draws but in a good way not in a no stalemate way. And a fortiori no pre-arranged draws - B - no more rapid tiebreaks. You can play chess w/o Armageddon and then settle classical matches w/ classical tiebreaks - C - Can have best-of-1 knockouts - D - All single round robins & single swiss are fair. - E - There's no more issue of drawing a best-of-4 by compensating for a white loss with a white win & 2 black draws like in 2016 & 2023 classical wcc's where Sergey & Nepo had more black wins than Magnus & Liren. Plus, at least in rapid, bids for black in 9LX go like 12min/15min while in chess they're like 9min/15min since 9LX doesn't have as many draws or as much white advantage. I expect classical armageddon bids will also be lower in chess than in 9LX. I notice these 3 improvements of Bobby - 9LX - Increment - Armageddon (w/ auction) Are used more in rapid than classical but they should be used more in classical! They also eliminate the top 3 worst things about classical-time classical-variant chess: 1 - theory 2 - dirty flag 3 - draws

Leela sacrificed a piece in the opening for a big lead in development and to gain space. Ng5 traded black’s only active piece. At 6:23 black struggles to untangle and develop any queenside piece. The queenside pieces are also bad pieces because other pieces and pawns are blocking their activity. At 10:17 black gave the piece back since the queen being the only active piece is not enough. The bishop is tied down blockading the e6 pawn so Leela is still better.

[@spindoctor6385]

Thank you for your take on engines. I find it strange that so many people believe that "stockfish says" is not only objective fact but actual knowledge that they themselves posess. The description of innacuracies, mistakes and blunders are taken as some kind of gospel. Some so called inaccuracies put your openent in a position where they have to play five or more precise and difficult to find moves, that is most often far more likely to end in a win than the suggested move that can put you in that position. They are no doubt very usefull tools but the plate of salt is a great description.

[@cptnoremac]

Yeah, the engines evaluate the position as though they're playing against another engine that never makes a mistake. So if it's in a losing position and it can either A) Make a move that simplifies to an endgame that your uncle could win but postpones checkmate for 20 moves, or B) Make a move that will result in getting checkmated in 7 moves but only if the opponent makes 7 extremely precise moves and otherwise is actually a draw, it'll play A every time.

A new research paper has found a really beautiful idea, demonstrating for the first time that it is possible to train a neural network to play chess at a grandmaster level without relying on explicit search techniques.

The scariest part about engines is how they operate logically beyond even numbers calculation. It sacrifices a peace to render multiple pieces of the opponents useless and effective unplayable.

[@alang.2054]

Not all engines are "ai", for example stockfish is just regular algorithm. Furthermore something like "ai" doesn't really exist. Those engines are just neural networks which are in essence fed by large amounts of data. They don't make any logical connections, nor play chess like humans, they just choose the move that makes the most sense based on data they had before. 2000 years ago people like you were scared of eclipse, because they didn't understand it, now people like you are scared of ai for the same reason.

100 games is a lot and thy definitely did not play that many. Leela won 3-1 and advanced to the next round of the cup. This was part the 1st round of cup13. Only 2 game pairs (2 openings, engines get to play both sids of each opening once) was played by default unless a decisive lead is reached before that (at least 2.5-0.5). If tied after 2 pairs, extra pairs will be played until a decisive pair is found. As time control is 30m + 3s, there's not really resources to be playing 100 game matches in a elimination tournament with 32 participating engines. 100 game matches are reserved to the most important events like the superfinal as it would take 4 days with this moderate time control.

[@Bosshog-WealthHealthBetterment]

This reminds me of when Leela first burst onto the scene and destroyed Stockfish. When you look into the games highlighted in the Gamechanger book, a constant theme was that Leela would be down material but would practically immobilize Stockfish. Having 3-4 pieces bunged up, and typically on the queenside, was an absolute hallmark. Sometimes I wonder why Tucan didn't sac the knight sooner (for example after e4, play Nc6. It forces the exchange and restores parity, plus gives you some room to breathe. Leela has sacked a whole piece for the position. It's obviously objectively wrong (Tucan is 1K points higher than me!!), but for an intermediate human that feels like the right approach to give back the material, what else is better?

What really impresses me about engines is that they are not just better than humans in seen patterns of a position. They are also better because they search through millions of positions per second. So basically, an engine does a move because it belives that it will lead to a position 15 moves ahead in which it saw patterns that it liked.

[@Yusuf_K7]

That has already happened with the AlphaZero match against Stockfish a few years back. What the top players noticed was AlphaZero’s propensity for pushing the h pawn. This was then introduced into the play of many top players.

[@kimgysen10]

I don’t think so. Humans will likely hold on to material in the majority of times because the number of combinations is too much to process for the human brain to avoid mistakes. Intuition could help but you’d still end up with an inconsistent human player. Imo.

[@realderek]

Please always keep that picture of Cortana for Leela. It provides such a great atmosphere of mystery and intrigue!

[@livtulc]

Yes but at move 57, Leela played Qc7+ and then 6 more moves, but she had Qd8 which needed just 5 more moves till checkmate. It's possible that she doesn't care of checkmating faster after all, as long as a checkmate has been seen.

[@pizdaloverbby]

the crazy thing tucano held for 79 moves.

[@TomTom-rh5gk]

You did a good job with variations. Thank you!

[@nicbentulan]

What do you think of nDWpjxXYLZ4 ?

[@eduardouchoa307]

The most efficient way of generating "brilliant games" is by using two engines with a 300-point rating difference. The weaker engine simply does not see the traps of the stronger engine, and yet, from a human POV, it is not committing any blunder

[@divergentlife493]

Robot games the best. I found this channel because of watching Alpha 0. I wonder which the strongest robot currently. I guess this LC0? Really need more robot presentations like this.

[@nabildanial00]

stockfish is still the best engine out there, but leela is a close second.

[@user-hn8lm8th8k]

Agad, thank you for this upload. Your personification of Leela is my favorite of the many images selected to represent Leela. Hauntingly scary/sexy/inviting in an other-worldly way. Classic and still alive thanks to you. Best wishes and be well!

[@hanszauner6036]

The crammed black position reminded me of Game 6 of the first BigBlue-Kasparov match in 1996. Kasparov didn't sacrifice a piece at the time , but slowly and methodologically improved his position and worsened BigBlue's, and finally won the game - probably the last game of any importance that a human has won against a strong engine.

[@theMarcoLee]

Wow. I was laughing the whole video. Those moves are insane. And to think that they were played against an engine that would obliterate any human is mind blowing. Thanks for sharing.

[@oxey_]

I love that throughout the years you've kept making Evans jokes when someone (or something!) plays b4 lol

[@conjurermast]

You've made a very good point about the engines not knowing the best moves either.(at least in the early midgame) It's so jarring to hear commentators treating the engine moves as if chess were solved & those were the best possible moves in existence.

[@hossain8463]

Thank you,Agat.... Please, continue these series of engines.Any

[@coolgamebro2611]

I love your videos for 5 years now Agad!

[@npyrhone2]

I've actually for some time hoped to find a good video about how the cutting edge chess engines actually work and how they differ. The absolute best thing would be to hear about that from you!

[@jessejordache1869]

Yeah, I've thought about that too. The years that I looked at the engine to see what the absolute best move was predate Alpha Zero by over a decade. I was willing to swear by the word of what would be considered a weak engine. Although at the time, the limits of calculuation were obvious in certain positions: I had trouble in Spanish middle-games, and using an engine to better understand them DID NOT WORK: they would just advocate either making non-moves, or they would suggest a move that I now recognize would objectively weaken my position, like the wrong pawn in front of the king going up one square. But still I thought that if Rybka says it, it must be true.

[@georgex9543]

How about partway through the game between these 2 engines have them switch sides and see if Leela can pull it out?

[@darthjarjarbinkstherealsit6832]

That's signature Zero-engine play. Sacking a pice to lock the rest away.

[@ebrahimartang7732]

Wonderful game! Please show more games from Alpha Zero or Leila or other engines. Those are awesome 👌 ❤ Thanks

[@Archerforthelord]

14:18 When you call customer service and the reps name is Leela.

[@apollion888]

"this looks like something your uncle would play" still laughing ...

[@bestofsatish]

knight sacrifice at the beginning to trap black pieces is unthinkable

[@paulmaul2186]

Awesome to watch.

[@patrickmihalcea6480]

I love a few engine games a week. Would like to see more!

[@jonathantsou9255]

That is a super dedicated father-in-law!

[@weavehole]

#suggestion Holly vs Queeg Red Dwarf Season 2 Episode 5

[@IngieKerr]

Heheh. My inner monologue voice when ever I play chess tends to be either Agad' saying something like "...and ingie plays knight to f3, fully developing his pieces", or Holly saying "Horsie, to King Bish' 3"

[@mukmin01]

16:25 We all knew it wasnt because of beauty, but because of winning b4 move LOL

[@joycejulep9115]

I love these Leela games ☺

[@a.m.armstrong8354]

The only Hu-Man who played chess like this was Bobby Fischer. This is musical, a Bach Symphony to match the Mozart of Fischer-Spassky 1.0, game 6. Stunning!

[@julianh7974]

Such an aesthetically beautiful game. Leela sacrifices a piece early on in a well known opening with no obvious (except to Leela) benefits. I still remember the amazing Alpha Zero game in which Alpha Zero put Stockfish in to Zugzwang. So pease show us some more beautiful engine moves. And how about doing what you usually do with human games - telling us what your engine says about the moves. What did your engine think of the piece sacrifice at the start of the game? Maybe that would prove your point - that an engine's analysis might sound convincing until another stronger engine comes along to refute it.

[@alessandrobaca8124]

@agadmator I would really appreciate the comparative analysis between different modern systems. Please do it :)

[@satyamevajayate1138]

Just Imagine Hans niemann playing against Leela.. "Chess will Never speak for Hans for a million years to come"....😂😂

[@asdfasdfasdf383]

Would love to see the different fundamental ideas in engine intrinsics. Maybe in a future video?

[@MrSupernova111]

Wow! Insane! Thanks!

[@LukeLongboneOfficial]

“Or so he says. Heh.” -Agadmator

[@tomhejda6450]

Note that this is a sacrifice for a very small positional advantage after Tuc gives back the piece. That's the point: we can spot really strong positional advantages with a sacrifice, engines spot much more subtle ones.

[@mikemartin5340]

A huge huge plate of salt, baby!
