[@fburton8]

I've really been enjoying this series of videos on Leela Chess Zero (and the earlier ones on AlphaZero too) - and yes, I think I do learn something from each one. :) Thanks Jerry!

[@isteinsvik5995]

What about a game with Leela winning as black? ;)

[@lukechavhunduka2970]

Øistein Søvik check out Kingscusher he did a video where she beat stockfish 9 with the black pieces

[@Narrowcros]

It's an it not a she, and that was Stockfish 6. it doesn't stand a chance against stockfish 9 or 10,calculations are way too deep for it.

[@Cscuile]

I second that fburton8

[@JB_inks]

13:21 - I know Leela is brilliant but even I'd be impressed if she could move her bishop like that!

[@sooooooooDark]

14:28 i think leela did that so the white king/queen could see each other a last time before the war thickened

[@JimmyJJJohnson]

Beautiful 😂

[@freshrockpapa-e7799]

Mr GM_Carlsen lol thanks for pointing it out

[@ginoginoh]

You can move the bishop like that if you are a GM

13:18 - that black bishop boldly attacking the king on a white square cracked me up for some reason. xD

[@rmendeljacobs2832]

13:25 Nice arrow drawing for the bishop 😂😂😂

[@mohd1nagyyyyy]

I am a simple man. I see Jerry and leela together I press like.

[@MrRishik123]

[@michelemeriggi]

Now when i blunder my bishop in bullet i can say im as good as leela (;

[@shaikriyaz1874]

This is sensational, really. Excellent work by Jerry as usual, which we have grown accustomed with

[@Nagaros]

Please continue with these highly instructive games !

[@truthcrackers]

Delivered with your usual clarity. Keep making videos!

[@scorchedBoard]

Alpha0 used to crush the light square bishop, but leela0 crushed the entire queenside pieces!! So aggressive..

[@AScentOfPhoenix]

This is what is known as a "positional sacrifice." Great job by Leela, and an excellent job presenting and analyzing this game by the uploader.

[@collinstump9706]

For the viewers who may be confused, you must be a GM to move a bishop like that @13:20 Another great video, Thanks Jerry!

[@JWalkLance]

Jerry, I absolutely love your analysis and commentary style - the best IMO. Many thanks for your excellent videos.

[@pyro-is-magic8202]

From watching Leela and Alpha Zero, I feel like there is some big possibilities in strategies involving killing the opponents Bishops by messing with their pawn structure. That Bishop sacrifice killed the entire Queen side of Black’s board. Maybe one day we could see more GMs emulate this in their play. Anyways thank you always for the great content Jerry.

[@TheJungleRobot]

The way these engines do it require SO much calculation though, I don't think a human brain is even capable of calculating so many lines at once. But yeah, I wish it was possible too cause it makes for amazing games!

[@TheJungleRobot]

Thinking of it, Levon Aronian actually played a game that was somewhat reminiscent of this where he gave up the exchange and a pawn to just isolate the black queen out of the game. It ended in a draw, but that was a beautiful showcase aswell

[@ChessNetwork]

The play is certainly an eye opener. Thank you

[@rmendeljacobs2832]

I guessed the bishop move but I had no idea *why* it would be a good move. It just looked so ridiculous so I chose it 😂

[@quazzydiscman]

Ninnifier O.o, me too. Only because of the title of the video and seeing that revealed check by black's Bishop, I'm like "yeah, that's something a human would never do I'll bet it's Bc4..."

[@Bennerboi]

I saw it instantly, and I was like: "It's probably Bc4, I have no clue why it's good, but it probably is." It's so funny, because a lot of the time I see a really deep great move, but then I don't see the continuation that makes it a good move lol.

[@GEM4sta]

BeEJayLetsPlay Yeah, I'd say 50% of my losses are me spotting a deep sacrifice, haha. Who has time to read lines? Let's see if it works

[@mikem720]

No human as white would be able to convert without some luck, after bishop to c4. Black is going to be able to trade the position down in a human vs human game.

[@zarion1181]

That is very poetic. Nice!

[@abelhutten4532]

Really enjoying the frequency and quality of these videos! Thanks Jerry, keep it up :)

[@LthiagoR]

I came up with Bc4 not 'cause I understood the move, but because it was the most incredible and a little bit intuitive move. Thanks for the video Jerry!!

[@lilalexbmx]

Great game. Great commentary. Great production quality.

[@TheMarksT]

Absolutely unbelievable Bishop sac there, yet also very reasonable of course, afterwards. Very deep and creative programming this Leela Zero

[@fluxvital]

i really love the leela sacrificial strategy. We already seen this in others games from leela and this impress me every time. Thoses games are extremly instructives. Please keep it going

[@lawdogwales5921]

21 Bc4!! If that was played by a world champion in a title match it would go down as one of the greatest moves in chess history.

[@fdllicks]

that was a fascinating video. The bishop sacrifice for positional gain. WOW

[@durimkid_9362]

Thanks Jerry!! Much love

[@maxlisk80]

Schliemann briefly rose from grave and applauded this game

[@petergregory7199]

21 bc4 is a stunner. Blew my socks off! Leela doesn’t mess about. Especially when she’s playing chess.

[@rohith.prabakar]

I did get the BC4 move. Reason 1 - I guessed that it was probably a sacrifice. 2 - I remember Anand Aronian game 2013 had a similar move. It was a just a blind guess tho. Great video as always!

[@LionHGH]

It's crazy watching you analyze a bullet game that's played better than two super GMs in classical time format.

[@irlrp]

I love that you showed small opening traps that us, mortals, could easily fall in, but those computers are WAYYYYYY ahead of those moves and explaining them would be irrelevant in this "4000 elo" context I learned so much (i'm a "beginner", i mean, i play chess regurarly but i was oblivious to the opening traps you showed)

[@mradeelmalik]

Even before you're asking about pop quiz, i was thinking the same to sacrifice white bishop. Recently watching so many games of Leela and my game strategy also change from defense to attack. Great Game and Great Analysis.

[@ChessNetwork]

Nice! 😎

[@yusufceylan5144]

Great analysis Jerry, thank you so much !

[@ChessNetwork]

Thank you Yusuf.

[@andrewweakland9197]

Still come back and watch this, one of the nastiest games I’ve ever seen

[@TranscendentalTunes]

One of the most beautiful bishop sacrifices ever! Makes so much sense - if Black gets his pawns rolling it's game over for White. Makes sense, but not easy to find

[@YAMI-co8fq]

I'm jealous of your warm clear confident friendly voice.

[@eldritch43]

Seems like leela is already above human level. Im especially impressed by the way it plays in. Its much easier to follow the game then any other classical chess software. There seems to be a motif and a clear theme permeating and its play. Referred to as "human like moves" by some people. Thanks for making these videos Jerry by the way :) thumbs up

[@adeptsang]

Super cool analysis. This was instructive

[@Moronvideos1940]

You are an excellent commentator and analyzer Thanks a lot.

[@Taubenschmied]

Funny, when you said 'I wonder how many of you are gonna come up with this', Bc4 was the first move that came to my mind. However, I did not see white's pawn move as a follow-up. I only saw Bc4 dxc4 Qxc4+ Be6, so I abandoned the thought. Great video as always, Jerry, you are doing such a fine work by all these analyses! (This is just one of the many ways this comment could have ended, pick your favourite one.)

[@XIIchiron78]

This was a really cool game. I always learn a lot from these!

[@sava-lakicevic]

I had stockfish 8 running on the side, it needs a minute to realise how good the moves from Leela are, it sometimes showed her losing, and then changing the evaluation to ~0, or from losing to winning even. Amazing what Leela has shown us. I wanna see AlphaZero vs Leela!

[@sarahbeanTX]

Savva Lakichevich and Leela had 1 minute for the whole game.

[@haikuaday8253]

instructive as always, jerry. Thanks for these!

[@reshad8570]

I came up with that wild bishop move when I watched this video for the second time! Wow! I must be really good at this!

[@scalethemachine]

Nice game. Interesting to ponder the mystery moves!

[@marcusklaas4088]

Jerry. I love these Leela Chess videos. Really fresh strategies and insights. I find that Leela and Alpha Zero in particular do a really good job at evaluating positions where they are down piece-wise, but the opposing pieces do not contribute.

[@liam314]

Thanks Jerri, love this series 👍

[@uprite88]

Nice pick of games, Jerry! which leads to moves never even considered.

[@bradc3402]

What an insanely deep move (B-c4). These AI's have an amazing ability to make these crazy sacs to put the opponent in an almost zewswang position. Amazing how they can calculate that the extra material is more then made up for in the opponent having all their pieces tied down. Very impressive chess!

[@KF1]

This was great! More games like this, please

[@trevorrogers95]

Jerry, you rock. Thanks again, man.

[@liammargetts]

Loving the daily uploads!

[@AnlamK]

Great video as always. And the quiz before Bc4 - I must say great trolling...

[@grandmasterofthrow6238]

Hi Jerry, this is everyone: We love you, Jerry!

[@natfrey6503]

More Leela reviews, please. Really mind-blowing chess games from "her."

[@GabrielGarcia-ni1qi]

Love the breakdowns or potential thought process for the game on uncertain or unforeseen moves throughout. Awesome video! Just subbed your channel 👍

[@sheikmohamedamanulaa3898]

A great promo like description for this video.....great effort and good commentary following u from 1 k subs........

[@chrisrichardson3206]

No way I saw bishop c4 😂 I definitely learned a lot from this game. Love your videos Jerry!

[@ima7mad]

Great content you’re makin lately Jerry. Keep it up, and I did actually predict the bc4 move.

[@ChessNetwork]

Nice 😊

[@peterpetrov6522]

Wowzers! Bc4! This type of sacrifice is out of this world!

[@peterhavord5984]

A recurring theme in some games for Leela and Alpha Zero is the way they go about paralysing some of their opponents pieces in the same way that Karpov did in some of his more famous games. However, Karpov seldom played the deep strategic sacrifices that Leela and Alpha Zero play.

[@mynameis1261]

I think, in such situations it is important to look through possibilities of black side to return gained material in order to avoid problems they faces in the game. For example, take one of the e-f white's pawns by black bishop. Anyway this piece almost useless, so black could do this. This "counter-sacrafice" can be done in different ways, some of them should be discussed But anyway, video is great as always, thank you :)

You mean an inaccuracy?! This is chess after all, inaccuracies are going to happen eventually

[@wooncheeleong7224]

These are just phenomenal players. Smarter than human beings

[@darioscumburdis2568]

Amazing game. Thanks Jerry

[@sciencetube4574]

I was actually thinking about Bc4 because I was looking for a way to defend against the discovered check and to disrupt the black passed pawns at the same time. And because you were saying stuff like "you will never guess this move", I was looking for crazy ways to do that. No chance I could have seen whether it was a good move, though, and no chance I would have ever even considered it while playing a game. This is a "you get it because you know it's a special move" type move.

[@ChessNetwork]

Well said ST 😊

[@ulbsualbrykya7141]

a mistake by Stockfish 6 in this game was after b4 by leela, sf6 replied with c5-c4. Evaluation was +1.82 at depth 33. a5 should've been played in reply to b4

[@Dundee1]

Very in depth and teaching, detailed to every grain, but i cant watch the whole thing without being on 1.5 speed as my only criticism is how some sections of explanation are drawn out although you teach me a lot.

[@SvetoslavBatsoev]

Great game, and great analysis, thanks.

[@ChessNetwork]

Thank you Svetoslav.

[@papashirt]

that was thrilling, thank you!

[@esamudani2845]

I most definitely didn't see that sacrifice, wow! What a move

[@V8SupersQirreL]

What a quiz at 6:30! No one would play like this!

[@willianbueno7293]

I don't know how long it will take but it is very clear to me that Leela it is on its way to be an alpha zero. thanks for the video Jerry

[@echoes6092]

I'm looking at this again two years later and I still didn't find Bc4. Wow. What a move!

[@NantucketSlim]

Finally figured out the Bishop move at 13:30. Awesome!!

[@IvarHuisman]

These vids are fun thank you!

[@TheKirkster96]

13:20 Jerry does one of his fancy bishop diagonals again!

[@richardschaffer5588]

Ms Zero loves her pawns! Leela seems to have figured out how to value her pawns and pieces depending their mobility in the actual position. That’s not a sacrifice of a bishop it’s a trade, an average bishop for a monster pawn pair. The hardest thing for us humans is to compare apples to oranges, AI no problem.

[@thelazymanatee2506]

When you ask for pop quizes I always check the weirdest moves, because I'm always a bit suspicious. And I actually saw Bc4, but thought that was totally insane, so I just clicked play again to see what it would be, knowing I was wrong anyway. In a game I would never even come up with this, not even close. But in a pop quiz the craziest moves are on my radar haha

[@russellfroggatt]

Another great game keep em coming

[@Scylaite]

13:19 bishop, seems legit

[@apostolosvrontos5792]

We die for those vids

[@filippostella6578]

That Bishop sacrifice is really "not human" =)

[@ashfan80]

I like the way the opening code and name stated in the given PGN

[@AnacondaHL]

13:19 that's quite the line for that dark square bishop!

[@LaukkuPaukku]

I briefly considered the Bishop-to-c4 move, but guessed h3 to scare away the knight instead.

[@francessavage7347]

Probably the most instructive game ever. This is my mums account I just had to say this. Hahaha . I know its engines and stuff but didn't leela have a chance to trap the queen or potentially completely upset the queens side pawn structure at an early point in the game. Pawn a4 threatening pawn b4 to trap the queen. Stock fish would have to push there a pawn to stop the a5 white pawn push. Suppose there is more important things on the table Haha.

[@francessavage7347]

1:50

[@Koillisaivo]

The bishop sacrifice reminded me of a move korchnoi played with black pieces against sairewan. Quite a cool game actually

[@Adam-hj1hc]

With it being Leela, I was thinking of ridiculous moves, and thought of Bc4 for that very reason of blocking the discovery check and coordination with the Knight. I would never consider this in a game, but wowee.

[@WarriorsCherub999]

very ! very good game and commentary😊

[@MrGyges]

Thanks Jerry. I didn’t spot the sacrifice ( rabbits rarely do ). Leela is most enticing, though my love of her doesn’t rival yours.

[@Fatalotti]

I came up with the Bc4 move, but only because I saw that the black c pawn could be pushed with check, and I realized that sacrificing the bishop there could stop that advance. However, I did not come close to working out the rest of the calculations.

[@sabelonsele68]

I come to think about this move Bc4 ! More and more as I watch this games by Leela same as the one of pawn invading space !

[@sabelonsele68]

Also if you'd notice from this games this sacrifice and ideas of advancing pawns always cramps the opponent pieces. Leela always gains and initiatives of relative force and flexible piece. In you last video of pawn invading space the Rook of h8 was just there chilling for the whole game , in this video the bishop is not flexible resulting to the whole rook on a8 just sitting there. So in a sense black is down a whole two pieces 😂😂😂 fuck what a beautiful chess !

[@doctorspock1930]

I found it!! But rather than claiming an easy victory (! but actually this move accomplishes a lot. There's the downside of dropping a bishop for zero material, but it's so forcing for black's play that it has to be at least a candidate move), I'd like to point out that in the commentary, 18. Bd4 looked out to me as a rather mysterious move even before the quizz. it's begging for black to activate a rather strong duo, almost immediately engages into a bishop exchange proposal, and it's a move that offers zero flexibility, the game continuation is almost forced and if white didn't have that 20. Bc4!! ressource, I think it's a refutation that Stockfish is headed into. So, found it, but only because Leela put my hands on her bishop. Take that, Stockfish!

[@stevenperry124]

It's possible I would have found the Bishop move if you gave me 100 guesses... but I couldn't have told you why. Nice analysis, by the way.

[@MrStarchild3001]

Wow! This was quite something.

[@arthurashworth6264]

Very interesting game! I found Bc4 only by guessing the most mysterious-looking move ;)

[@one_uniform]

Great caster!
