Info about Leela Zero:
en.wikipedia.o...
...
Leela Chess Zero (lc0) is a free, open-source, and neural network-based chess engine and distributed computing project.
Leela Zero's algorithm is based on DeepMind's 2017 paper about AlphaGo Zero.[3][6] Unlike the original Leela, which has a lot of human knowledge and heuristics programmed into it, Leela Zero only knows the basic rules and nothing more.[7]
Leela Zero is trained by a distributed effort, which is coordinated at the Leela Zero website. Members of the community provide computing resources by running the client, which generates self-play games and submits them to the server. The self-play games are used to train newer networks. Generally, over 500 clients have connected to the server to contribute resources.[7] The community has provided high quality code contributions as well.[7]
Leela Zero finished third at the BerryGenomics Cup World AI Go Tournament in Fuzhou, Fujian, China on 28 April 2018.[8]
Info about Alphazero:
en.wikipedia.o...
AlphaZero is a computer program developed by the Alphabet-owned AI research company DeepMind, which uses an approach similar to AlphaGo Zero's to master not just Go, but also chess and shogi. On December 5, 2017 the DeepMind team released a preprint introducing AlphaZero, which, within 24 hours, achieved a superhuman level of play in these three games by defeating world-champion programs, Stockfish, elmo, and the 3-day version of AlphaGo Zero, in each case making use of custom tensor processing units (TPUs) that the Google programs were optimized to make use of.[1] AlphaZero was trained solely via "self-play" using 5,000 first-generation TPUs to generate the games and 64 second-generation TPUs to train the neural networks, all in parallel, with no access to opening books or endgame tables. After just four hours of training, DeepMind estimated AlphaZero was playing at a higher Elo rating than Stockfish; after 9 hours of training, the algorithm decisively defeated Stockfish 8 in a time-controlled 100-game tournament (28 wins, 0 losses, and 72 draws).[1][2][3] The trained algorithm played on a single machine with four TPUs.
...
Relation to AlphaGo Zero
Further information: AlphaGo Zero
AlphaZero (AZ) is a more generalized variant of the AlphaGo Zero (AGZ) algorithm, and is able to play shogi and chess as well as Go. Differences between AZ and AGZ include:[1]
AZ has hard-coded rules for setting search hyperparameters.
The neural network is now updated continually.
Go (unlike Chess) is symmetric under certain reflections and rotations; AlphaGo Zero was programmed to take advantage of these symmetries. AlphaZero is not.
Chess can end in a draw unlike Go; therefore AlphaZero can take into account the possibility of a drawn game.

Rapidly Evolving Leela unleashes a stunning rook sacrifice vs Stockfish 10 (2018) : Replayable game with indented variations: www.chessworld.net/chessclubs/ltpgnviewer32/ltpgnboard.asp?GameID=5023965&v=cDbOG_oMABs

[@liamhalliday8437]

Whenever I watch Leela (or AZ) I am always amazed at how they will go down material so long as they are up "active material". I lose count of the games where the opponent has bishops and rooks trapped on back ranks. Another super fun and original game, thanks for sharing.

[@kingscrusher]

Cheers, K

[@jeremykothe2847]

Yeah the astonishing thing is that they can evaluate the inactive pieces despite less depth searching - obviously the nn eval is keeping track.

[@kulkidspin7691]

far more interesting is if we can have a0 vs leela , chess will have a bright future indeed as they show how the game should be played properly

[@HellMoodio]

"is stockfish playing with fire?" - see what you did there ;)

[@kingscrusher]

Fun comment - Cheers, K

[@danielweberdlc]

I get the impression that the way to beat "brute force"chess engines is to determine a material sacrifice that gives a large advantage further out than the engines could ever see. Human players can't play precisely enough to take advantage, but computers can. really amazing stuff Granted, this is one game out of 100 million, but hugely entertaining. Maybe that's the future of chess, sifting through millions of computer games to find really entertaining ones.

[@kingscrusher]

Great comment, K

[@brettaspivey]

This has got to be one of the greatest games I have ever seen

[@kingscrusher]

Cheers, K

[@alexmagor]

I'd be curious if there any high level "Queen in SIberia" human games played in similar fashion with that type of rook sac (that wins).

[@dannygjk]

Oh yeah there are GM games in which one side sacs one of their rooks which hasn't moved.

[@douglasquaid7550]

Now that's a Siberian Queen.

[@kingscrusher]

Fun comment - Cheers, K

[@Varney_of_London]

Being able to sac material like Leela and Alpha Zero does (and get away with it against an opponent as strong as Stockfish) is amazing. I've been trying to practice playing like Alpha Zero and Leela does (my rating rollercoasters from the high 1800's to the low 2000's) and its way, way, harder to do than they make it look like. These machines are simply on another level when it comes to playing chess than us mere mortals...

[@petrabanjarnahor229]

I'm proud of Leela :") She grows so fast

[@kingscrusher]

Great comment, K

[@ilyakalinin2660]

When Stockfish goes supergreedy in the opening while playing Leela, he is certainly plaing with fire! It's Leela who beats him almost always in such cases.(At least Stockfish is struggling hard for his live's sake afterwards to find a draw)

[@kingscrusher]

Fun comment - Cheers, K

[@bhgtree]

Thanks KC and David. Test 30 is really getting close to T10 and with the LR drops to come, I think will surpass it. Also a wonderful achievement by Stockfish team, ten wonderful years of dedication, what a gift to the computer chess community.

[@kingscrusher]

Cheers, K

[@xyzct]

Geez, after watching 12 draws in the championship, this was so exciting.

[@maxsimes]

very interesting game, thanks for sharing. maybe one day leela will face alpha zero :)

[@GRESULLIVAN]

Again an amazing game from you Kingscrusher.. Thank you very much again... Our chess skill increases video by video from you!!! may the Force of Tal be with you!!!!

How can I play with leela zero on android thankyou

[@Bobby-fj8mk]

Leela made it look so easy - good game.

[@kingscrusher]

Cheers, K

[@patobrien6862]

What an astounding game. Thanks KC!

[@kingscrusher]

Cheers, K

[@J0sho495]

Insane game.

[@jeremykothe2847]

The title confused me a little - thought I'd just watched it, but it was just that the last game also featured a rook sacrifice - not as neat as this one though!

[@nickbrowne2938]

What!?!? Just crazy play by Leela. Loved every move!

[@RussellMark17]

THAT IS THE MOST BEAUTIFUL GAME I'VE EVER SEEN

[@kingscrusher]

Cheers, K

[@14thsomebodyelse]

İ was thinking this today if sacrifice the rook can queen be taken.. but it was still horrible i thought cuz it was 2 rooks and a pawn for a queen im not computer lmao.. i cant calculate that good to win that

[@julioandresgomez3201]

Wow, that´s really greedy from Stockfish 10. I thought classic engines were way past gaining pawns in plain opening.

[@kingscrusher]

Cheers, K

[@dragosenescu331]

This is on a completely different level

[@kingscrusher]

Cheers, K

[@jamesmicheal3944]

Damn Leela is just unbeatable now a days . Great game by Leela Amazing rook sac. Great coordination in Leela pieces . I cannot believe how Stockfish 10 fall to that pawn sac. Poison pawn . The Queen check is a serious violation of chess principles in the Opening .

[@mustafaunal1834]

Good analysis for KC and good play for Leela Test 30 Network.

[@kingscrusher]

Cheers, K

[@spiritualphysics]

6:41 Nice comedic shot....

[@kingscrusher]

Cheers, K

[@paulbloemen7256]

Interesting opening! The whole rook grabbing is advantageous for White as long as he plays 9. Nbd2, until that move there is nothing for Black that gives him an equal game? So, 5. Qa4+ is sound, and dangerous for Black?

[@kingscrusher]

That does appear to be the problem line indeed.

[@How_To_Reach_2000_At_Chess]

I tested this game with Stockfish, and it gives...11.a4 as being the best continuation. For example, 11. a4 Ne5 12. a5 Qb4+ 13. Nd2 Nbc6 14. Qxf8 Bxf8 15. dxc6 Nxc6 16. e3 Nxa5 17. Ra3 Qc5 18. Kd1 Nc6 19. exd4 Qxd4 20. Rc3 Nb4 21. Rc4 Qb6...and white is winning. Obviously I don't know what Leela would play, but Stockfish evaluation for 11. Na3 is bad, and it eventually descends rapidly for 11. f4, but it think that it's winning after 11. a4, and can't see a better continuation for black than 11...Ne5.

[@kingscrusher]

Why 12...Qb4+ ?

[@joseraulcapablanca8564]

What a conception the rook sacrifice. It almost makes me want to play Grunfield again. Very amusing and insightful analysis. Thanks KC keep up the good work

[@kingscrusher]

Cheers, K

[@marcweeks9178]

The sacrifice reminded me of the a1-rook sacrifice that Kasparov made against Anand in the World Championship. It didn't matter that he was down a rook, because Anand's king was stuck in the center of the board and on the losing end of all sorts of tactics.

[@joseraulcapablanca8564]

Marc Weeks yes I had not thought of that but it was a similar thing. That too was a great game

[@Ytremz]

S10 is too focused on being up material.

[@ramdamdam1402]

tremendous, what were the time controls ?

[@kingscrusher]

40 moves per 2 minutes - with 2 sec increment per move

[@zaksmith1035]

So beautiful!!! Can I tag you if I do some stuff on our game in a video? I want to do it because Leela played wonderfully in it. I won't use your analysis from your website, and will mention your name. Good? Can't believe Leela and Rook Sacrifice. Tied up Stocky. Like Bobby, against Spassky. Kasparov soon.

[@kingscrusher]

Sure and Cheers, K

[@cr35t23]

I watched a bit of the computer chess championship and Leela was getting whooped. It was next to last.

[@shakyricLshadow1111]

Yeah. Leela takes some time to learn because unlike a0 its not using godly hardware. With that said, it'll be interesting to see how quickly it will surpass the others. I think in months it will clearly be the strongest... And in a year?

[@kingscrusher]

I think that one was from a long start position to go over World championship Game 12 - in the normal ones Leela does much better. Cheers, K

[@Arc_Soma2639]

So did Leela really won againts stockfish 10? SERIOUSLY?

[@kingscrusher]

Cheers, K

[@kshoggi]

Yes but the opening was chosen for the engines

[@dannygjk]

@@kshoggi SF decided to eat the material tho it wasn't forced to do that.

[@quizazle4204]

What was the nps for each side ;)

[@RalfStephan]

Does David Groebner (sp?) have a twitch stream where one can follow these Leela-Stockfish games?

[@bkhattingen]

No he doesn´t and isn´t intending to either :-) Cheers, David

[@RalfStephan]

@@bkhattingen Well, then I can at least thank you for your work in this forum.

[@quizazle4204]

Hey, what hardware was this run on?

[@JimothyMcgee]

@@bkhattingen Hey, what hardware was this run on?

[@dannygjk]

@@bkhattingen lol

[@dwyingling]

Can someone tell me why the machines aren't allowed to finish the game by themselves?

[@bkhattingen]

It´s shortens the process of testing without changing the result. In a 100 or 200 games match this spares loads of time. So if both engines agree that one side is better by at least 700 cp for more than 5 moves the game is adjudicated.

[@dwyingling]

@@bkhattingen Thanks

[@kingscrusher]

@@bkhattingen Thanks David :) - a lot of comments on this game - nice game choice indeed :)

[@dwyingling]

@@kingscrusher As a follow on question.... Why are the computers provided an opening book instead of them starting the game themselves?

[@dieghito525]

Another amazing game for Leela0. Leela0 ha mai perso una partita contro Stockfish? Can you tell me Kingcrusher please?

[@Gamimaru1]

si. le partite che vince leela contro stockfish sono solo quelle in cui le aperture sono state predecise. stockfish 10 è più forte di leela. per ora.

[@SpiritualFox]

2:06 I think this Rook sac is book. Or it is now. Welcome to the computer age. 5:30 What's Leela's Queen worth? 8? 9? 11? _EVEN MORE._ 6:30 H3? Stockfish is totally lost, huh? 8:43 How much is Stockfish's H1 Rook and F1 Bishop worth? One, maybe two pawns. Look at that immobile IKEA furniture. Queen should take both for double reward miles.

[@kingscrusher]

Fun comment - Cheers, K

[@SpiritualFox]

kingscrusher Thanks. Dunno if i can do the same for a Carlsen game. "He takes 0.02 pawns by moving one of his pieces back a space! Another incomprehensibly subtle move in a dead position! Thank heavens he's hot, because it's back to staring at him for another 5-10 minutes."
