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.

We now need a follow up video where KC plays this trap against humans in the advanced French.

[@warrendsmith6832]

If two human GMs had played this it would have been one of the greatest games of their lives, but for these silicon monsters it is a freaking superblitz speed game. Damn.

“Guess what Leela plays next”. With a title like that....hmm....shucks.....I have NO idea!!

Everyone loves a queen sac. I have been ill for a week. Have missed your KZbin work great to see you enjoying the new improved Leela. Thanks KC keep up the good work

[@Jiffy_Park]

Hi KC I always enjoy your leela videos but could you consider getting a better microphone? The audio quality could be a lot better

[@khem1652]

that damn d4 pawn cannot be captured :)

[@Norpan506]

not anymore :)

[@xyzct]

Soon the Milky Way will be used a thorn pawn in Leela's relentless quest for total domination as our Intergalactic Overlord. Then you're _really_ going to wish you bought one of KC's t-shirts.

[@Pintkonan]

are KC'S t-shirts supposed to survive the overkill?

[@marcuslarwa9098]

That poisonous pawn was really nasty.

[@vargas2022]

You're right. We should all play the advance variation due to this mega trap :)

A great game ,thanks Crusher ,you're great too!

Engines can't offer draws :P

[@EpsilonCentenarian]

Hi Kings, thanks for the video. I was looking at your analysis of the missed draw opportunity at 11:45 in the video. I think after rook h1, pawn h4 prevents any draw opportunity. Wondering what you think. Loving the LC0 games. Thx again. Edit: Pawn to h4 seems to be losing for white. Since, you didn't cover that variation, I was wondering if you overlooked something. But there was nothing there.

[@jesussavior6383]

WE NEED YOU KC MOVE STOCKFISH VIDS LOVELY (((l

[@travisheck5979]

You know, I'm curious to see what kind of weakness(es) Leela has to overcome in the future. Perhaps you could annotate one or two games where Leela loses? Not too many, as I love Leela and like seeing her win spectacularly ;) THORN PAWN!

[@gabrielmillee8745]

Its very nice I'll have to study this

[@primeobjective5469]

Blasted rook at the end, he knew he could not be touched!

[@matth571]

Kingscrusher, you should do a man vs machine match and pick a strong club player to expert rated chess program such as fairy max, fruit or some other type of 2000ish rated computer and do like a three game match I think a fairy max chess match would be especially interesting

[@Hazy2425]

Seems like there was only a drawing chance with 46....Rh1 because 46. Bg5 is a mistake. Seems like 46. Rd7 or 46. Rf8 win.

[@kingscrusher]

Cheers, K

[@Mighty_Deeds]

Is it fair to say that so far only Leela and A0 Consider the king as a potential asset rather than a constant liability?

[@victorpetrescu6586]

Impossible to say such on a limited number of games. Why would stockfish bring out his king if for the most part it has no reason whatsoever to

[@chesslover2925]

Dear KC. At 10:42 why stockfish didnt play pawn f6 ??????

[@miespetmiespet440]

hoi what about king h4 afther queen g6 check ??? seem he escape behind pawn and knight and win !!!!

[@Bert86]

I have a question, will the stockfish team try and program the engine in a way that now plays more like the machine learning engines since they have demonstrated to us another way of playing chess? that would be cool

[@kingscrusher]

I hope they stick with the main AB approach for a while at least to see if taken to the limits, it might be able to compete with evolving NN networks.

[@jesussavior6383]

[@Aliens-Are-Our-Friends2027]

WHY STOCKFISH NO DRAW?

[@aesirvanir8671]

Thank you for the analysis. ..h5 seems peculiar to the human eye; my "fresh of the press" SF10 did not consider the move either! What anomaly in its calculation led to the move materialising on the board? -- what _cul de sac_ did SF10 see looming in the depths of its analysis tree?

[@kingscrusher]

Great comment, K

[@jnizamani]

There is no draw option.If rook attacks the h pawn,white move h4 will stop the perpetual

I am not so sure - it was a fast time limit. Cheers, K

[@piyushsharma5938]

@@kingscrusher i checked with my stockfish. ... Rh1 is a sure draw. .... however stockfish suggests Rd7 instead of Bg5.. on Bg5 black can reply with Rh1 and force a draw. .. Anyways thanks for yet another beautiful game. ... I am learning so much

[@jnizamani]

I was also surprised.so simple calculations. why did stockfish not calculate it? I concluded that the way these algorithmic engines are calculated ,carry a weakness.They concentrate more on defense.where they see a threat there 99.99% calculation work on defense.So They can not see an attacking defense.

[@simohayha6031]

Amazing all those stockfish fans say that oh Sf10 can beat A0 blabla and that Leela is nothing. Guess they ain't know this channel

[@kingscrusher]

Cheers, K

[@Stockfish1511]

Leela lost more games to stockfish than actually won. What makes you think A0 can beat sf. This pure hype.

[@simohayha6031]

@@Stockfish1511 and Leela Zero has only 3/4 experience of A0

[@ElieM1]

@@@simohayha6031 Dude, just admit you were wrong. KC shows us games where Leela wins because those are the games we want to see. But that doesn't mean that Leela consistently beats SF10. Don't make it about Leela's lack of experience because that's not what your original comment was about. You simply made a mistake when you assumed that KC's selected sample of Leela and SF10 games are representative of reality.

[@simohayha6031]

@@ElieM1 my comment didn't imply that SF ten is consistently beaten by Leela. You just want to interpret it that way so that you from YOUR point of view, can prove me wrong to save your SF ass. The fact that Leela can already beat this whilst not even at A0 strength shows that it is definitely possible for A0 to consistently beat SF. 8 or 10. Leela has a lack of experience compared to A0. It's true. It's about how many self play games they played. Leela has to accumulate self play games over a time span of months in order to grow to Sf10 power while A0 did all that work in a couple of hours on mega hardware. My comment is meant to show that Leela is of high caliber already (I've seen alot of ignorant people on other channels covering A0 games who seem to not acknowledge Leela strength). Furthermore it shows that, if a "weaker" version of A0 can beat SF ten, then surely A0 can. So all the dick riders who scream that Sf10 would defeat A0 are also put to rest.

Btw dear KC. Iam number one stockfish fan :(
